Sally Hemings Children
Sally Hemings' Children When James Thomas Callender published allegations in 1802 alleging that Sally Hemings was not just Thomas Jeffersons slave, but his concubine, it was the beginning but not the end of public speculation on the parentage of Hemings children. Sally Hemings Own Genealogy Sally Hemingsà wasà a slave owned by Jefferson who came to him through his wife,à Martha Wayles Skelton Jefferson. She may have been Martha Jeffersons half-sister, fathered by Marthas father, John Wayles. à Sallys mother, Betsy (or Betty), was herself the daughter of a white ship captain and a black slave woman, so Sally may have had just one black grandparent. à Nevertheless, the laws of the time made Sally, and her children no matter who was the father, also slaves. Birth Dates The birth dates of six children of à Sally Hemingsà were recorded by Thomas Jefferson in his letters and records. Descendants of Madison Hemings and Eston Hemings are known. The evidence is mixed for a son who may have been born to Hemings when she returned from Paris. Descendents of Thomas Woodson claims that he was that son. One way to look at the likelihood of Jefferson as the father of the Hemings children is to see whether Jefferson was present at Monticello and whether that is within a reasonable conception window for each child. The following chart summarizes the knownà birth dates and the dates of Jeffersons presence at Monticello within that conception window: Name Birth Date Jefferson atMonticello Death Date Harriet October 5, 1795 1794 and 1795 all year December 1797 Beverly April 1, 1798 July 11 - December 5, 1797 probably after 1873 Thenia? aboutDecember 7, 1799 March 8 - December 21, 1799 soon after birth Harriet May 1801 May 29 - November 24, 1800 probably after 1863 Madison January (19?), 1805 April 4 - May 11, 1804 November 28, 1877 Eston May 21, 1808 August 4 - September 30, 1807 January 3, 1856 What Happened to These Children and Their Descendants? Two of Sallys documented children (a first Harriet and a girl possibly named Thenia) died in infancy (plus, possibly, the child named Tom who was born shortly after the return from Paris). Two othersââ¬â¢Beverly and Harrietââ¬â¢ran in 1822, were never formally freed, but disappeared into white society. Beverly probably died after 1873, and Harriet after 1863. Their descendants are not known, nor do historians know what names they used after their escape. Jefferson spent minimal effort to track them after their departure, lending credence to the theory that he let them go purposely. Under an 1805 Virginia law, if hed freed them or any slave, that slave would not be able to remain in Virginia. Madison and Eston, the youngest of the children, both born after the 1803 Callendar revelations, were freed in Jeffersons will, and were able to remain in Virginia for some time, as Jefferson had requested a special act of the Virginia legislature to permit them to stay contrary to the 1805 law. Both worked as tradesmen and musicians, and ended up in Ohio. Estons descendents at some point lost their memory of being directly descended from Jefferson and from Sally Hemings, and were unaware of a black heritage. Madisons family includes descendents of three of his daughters. Eston died January 3, 1856 and Madison died November 28, 1877.

Heres How to Make Non-Toxic Homemade Tattoo Ink
Here's How to Make Non-Toxic Homemade Tattoo Ink The earliest tattoo inks came from nature. You can use non-toxic natural ingredients to make your own homemade tattoo ink. One common tattoo ink recipe is simple and has been used in various forms for thousands of years. Its sometimes called wood ash ink,Ã carbon black tattoo ink, or a poke-and-stick tattoo. How to Make Tattoo Ink The earliest tattoo inks were prepared by mixing ashes from completely burned wood together with water. The wood ashes were nearly pure carbon, which yielded a black to brown tattoo. While carbon is the base for modern tattoo inks, its not a great idea to use water as the liquid to suspend the ink (the carrier). While a homemade tattoo ink may be prepared using sterile distilled water, poking the ink into the skin will force bacteria on the skin into the deeper layers. A non-toxic disinfectant, such as vodka, is a better choice. Vodka is a mixture of alcohol in water. Any other white alcohol, such as rubbing alcohol or tequila, will also work. Prepare the ink from: one cup carbon black ashes (completely burned wood)just enough vodka to create a slurry Prepare the ink by mixing the carbon black and vodka in a blender (15 minutes to an hour). If the mixture is too thin, add more carbon pigment. If the mixture is too thick, thin it with a little more vodka. It is best to prepare fresh homemade ink for each use, though the ink could be stored in a sealed container away from sunlight and blended again. Its a good idea to wear a mask and gloves when applying a tattoo to prevent the spread of infectious agents. The tattoo can be applied using a pin or quill that is dipped into the ink and poked into the skin. Notes About Wood and Paper Some people make this ink by burning wood in a heat-proof bowl. The advantage of using paper is that it produces fine carbon particles. The disadvantage is that some types of paper are treated with chemicals (e.g. heavy metals) that may remain in the ashes.If youre using wood, be aware youll get slightly different results depending on the species of wood you burn.If you know youll need multiple batches of ink to complete a tattoo, its a good idea to use the same source for the carbon each time and to keep track of how much ash and liquid youre using. Careful measurement will help ensure each batch has the same particle density, which translates into color intensity. Tattoo Ink Safety Notes While you can prepare your own ink and give yourself or a friend a tattoo, this is not a good idea for most people.Ã Professional inks are much more consistent in quality and safer to use, so they will give you better results with less chance of a reaction to the ink. Also, tattoo professionals are trained in aseptic techniques, so you will have much less chance of getting an infection or accidentally puncturing a blood vessel if you get your tattoo inked by a trained artist.

Modern Business Research Methods Essay Example | Topics and Well Written Essays - 1500 words
Modern Business Research Methods - Essay Example through research. Research is all about fact gathering, relating facts with a focus idea, analysis, drawing conclusion and lastly acting and implementing. Over time, with technology emerging new avenues have been developed to collect data; each and every method of research is suited to particular requirements and factors and is used as per the benefit cost analysis of the situation. Some aspects of the past are studied either by perusing documents of the period or by interviewing individuals who have lived or have experienced during that time. An attempt is then made to study why certain things happened during that time and to explain as to why they happened. The documents that are generally consulted include newspapers, journals and magazines that were published and especially the data government and other private agencies maintain for both commercial and own use. The idea of conducting historical research does not indicate that it is unstructured; in fact, it is systematic process of searching for facts and then using the information to describe, analyse and interpret the past. The purpose of this research is to make people aware of what happened in the past so that they may learn from past failures and successes and to see whether they are applicable to present day problems and issues. It also assists in prediction and testing hypothesis concerning relationships or trends. FOCUS GROUPS: Focus groups are mainly interviews that let open discussion of the topic. They are generally used to develop new ideas. It has an objective and does not generally allow the discussion to deviate from it. People in focus groups openly share their thoughts, feelings, attitudes and ideas on the topic under the discussion. Generally, the focus group consists of 6-10 people at a time and a moderator who is responsible for facilitating the debate. The main advantage of focus group includes that views of many different people are gathered at one place. Since it is less formal than the structured interviews thus participants feel comfortable sharing their perspectives. Some of the drawbacks of focus group include that the views of individual participants are generally influenced by other participants and may indulge in group think. Moreover, it is difficult to gather people in one common location at a time. SURVEYS: This method involves asking the individuals questions which might be open or close ended. Surveys can be orally done or through written questionnaires. It is helpful in gathering primary data through a large number of audiences. The best part of using survey as a method of research is that they can be done face-to-face, via telephone, emails, fax etc. And thus it helps the researcher reach a mass number of respondents to gather information. Surveys can be cross-sectional or longitudinal Surveys are generally done to gather informa

International education Essay Example | Topics and Well Written Essays - 1000 words - 1
International education - Essay Example Relevant t the above, it is important to note that the Australiaââ¬â¢s International Education Industry accounts for the fourth largest export industry in the region (Davis and Makintosh, 2011). On this perspective, the nation has been getting more than 15 billion dollars annually due to the international education programmes. The industry has been experiencing massive growth due to the stronger influence of the international higher education. Other than the issue of being considered one of the most crucial export industries, the Australian International Educational Industry is estimated to host approximately eighty per cent of the students from Asia (Loras, 2011). This has contributed massively in ensuring that the country enjoys prestige as well as recognition in the international arena. The educational quality offered in the Australian institutions of higher learning has been one of the best. The standards have been termed world class (Mukerji and Tripahi, 2014). As such, several people have always been in need of joining these Australian international institutions. This follows that most students always like to associate themselves with institutions of higher learning that offer the best qualities in the world. The fact that the educational standards in these institutions have been of good international reputations has made several foreign students to join these institutions of higher learning in the region (Bretag, 2015). It is of crucial significance to note that the Australiaââ¬â¢s International Education Industry has massively contributed towards raising of the Australiaââ¬â¢s profile, as well as the Australiaââ¬â¢s global standing (Ramar et al, 2013). The education in the Australian institutions has really contributed towards increasing opportunities for business as well as promoting the issue of research activities. This has led to strengthening of many sectors within the country. Moreover, the

The Cases of Hirabayashi and Korematsu v United States Essay Example for Free
The Cases of Hirabayashi and Korematsu v United States Essay The United States, after the fatal attack of the Japanese in Pearl Harbor on December 7, 1941, was forced to enter World War II. There were a few of Japanese descent who, due to the immigration that begun since before 1885, were in the mainland America. Many feared what these Japanese-Americans would side on their home country of Japan that would possibly lead to a successful invasion of Japan. The fact that Japan has invaded one after another Pacific island where American forces were based did not help the public opinion of many regarding the Japanese on the United States. As a precautionary measure, President Franklin D. Roosevelt has enacted two executive orders to prevent incidents of subversions and espionage from Japanese-Americans. Two Japanese-Americans were found to be guilty of violating these laws which has ultimately brought their cases to the United States Supreme Court. On February 13, 1942, Roosevelt signed Executive Order 9066 which defined military areas in the United States and authorized the removal of Japanese-Americans within these military areas. The Order declared that ââ¬Å"the successful execution of the war requires every possible protection against espionage and against sabotage to national defense-material, national-defense premises, and national-defense utilitiesâ⬠(United States Supreme Court [USSC], 1944). It also provided assembly centers for those who will ultimately be transferred to evacuation camps. As a result, approximately 120,000 Japanese-Americans were in internment camps (Schaefer, 2008). While the evacuation carried out with little difficulty, there were those who militantly defied the order. The Japanese American Citizens League, an organization founded in 1924, hoped that cooperating with the American decision will lead to sympathetic consideration when the tension subsided. Of those who resisted the order was Toyosaburo Korematsu. Korematsu was a US-born Japanese-American who stayed in San Leandro, California and knowingly violated the Civilian Exclusion Order No. 34ââ¬âan order based upon the provisions of Executive Order 9066. The Civilian Exclusion Order No. 34, an order issued by the Commanding General of the Western Command, directed that ââ¬Å"all persons of Japanese ancestry should be excludedâ⬠from San Leandro, California (USSC, 1944). Korematsu was arrested and was found guilty of the violation. He challenged the constitutionality of the Order and held that it is in violation of the provision in the Fifth Amendment stating that no person shall ââ¬Å"be deprived of life, liberty, or property without due process of law, nor shall private property be taken for public use, without just compensation. â⬠The question of loyalty was not raised. Furthermore, the evacuees were forced, charged with no crime and could not leave without official approval (Schaefer, 2008). This is crucial in that, as Schaefer explained, the Japanese-Americans that were forced to resettle in evacuation camps were instructed that they were to carry only personal items. ââ¬Å"No provision was made for shipping their household goodsâ⬠and ââ¬Å"the federal government took a few steps to safeguard their belongings they left behindâ⬠(Schaefer, 2008). The Court (1944) decided that the need to protect against espionage from persons of enemy descent, of Japanese descent in Korematsuââ¬â¢s case, far outweighs their rights as provided for by the Fifth Amendment. The Court held that the military authorities were charged with the protection of the American soils. Furthermore, the Civilian Exclusion Order is in accordance to the provisions of the Congressional authority to the military allowing them to identify who should and who should not remain in areas threatened with invasion, espionage or sabotage. The court explained that they have no doubts that most of the evacuees were loyal to the United States. They reasoned that the exclusion of the entire Japanese-American population was brought upon the contention that the disloyal could not be immediately segregated from those who are loyal to the United States. The Court (1944) explained ââ¬Å"that there were members of the group who retained loyalties to Japan,â⬠a fact that ââ¬Å"has been confirmed by investigations made subsequent to the exclusion. â⬠It has been found that ââ¬Å"approximately five thousand American citizens of Japanese ancestry refused to swear unqualified allegiance to the United States and to renounce allegiance to the Japanese Emperor, and several thousand evacuees requested repatriation to Japanâ⬠(USSC, 1944). While the Court (1944) held that compulsory exclusion of large groups of citizens from their homes is inconsistent with basic governmental institutions, ââ¬Å"when under conditions of modern warfare our shores are threatened by hostile forces, the power to protect must be commensurate with the threatened danger. â⬠Finally, the Court (1944) explained that ââ¬Å"Korematsu was not excluded from the Military Area because of hostility to him or his race. He was excluded because we are at war with the Japanese Empire, because the properly constituted military authorities feared an invasion of our West Coast and felt constrained to take proper security measures, because they decided that the military urgency of the situation demanded that all citizens of Japanese ancestry be segregated from the West Coast temporarily, and finally, because Congress, reposing its confidence in this time of war in our military leaders-as inevitably it must-determined that they should have the power to do just thisâ⬠Another case wherein a Japanese-American has challenged the United States government, particularly of its military institution, was the case of Kiyoshi Hirabayashi v United States. This time, the guilty was found to be violating the Act of Congress of March 21, 1942 requiring all persons of Japanese ancestry to be in their place of residence between 8:00pm to 6:00am. The Act was also in accordance to Executive Order 9066. The Courtââ¬â¢s ruling was also in favor of the United States. While the Hirabayashi case was earlier decided, it has been greatly overshadowed by the Korematsu case due to the fact that exclusion was more extreme than that of the curfew rule. However, the Supreme Court decision made on the Korematsu case relied and affirmed the decision in the Hirabayahi case. Korematsu and Hirabayashi both challenged the constitutionality of the rules enacted based on Executive Order 9066. They claimed that the rules violated the provisions of the Fifth Amendment stating that no person shall be deprived of life, liberty or property without due process of lawââ¬âa provision that was violated when the military institution has apprehended Korematsu and Hirabayashi and all other Japanese-Americans without questioning and even the indication of treason or disloyalty to the United States government. Unsurprisingly, the United States Supreme Court ruled in favor of the federal government, giving precaution for espionage and sabotage from persons of enemy descent during the time of war as a justification for such rules imposed based on Executive Order 9066. They held that the rules were not insomuch as a racial prejudice against citizens of Japanese ancestry but was necessary for the war efforts to be successful. The Court, however, clarified that the rules based on the Order should only be imposed until such time when the war is over. The Japanese-Americans lost much of their property and were destroyed economically. After World War II, the United States federal government paid $35 million to the Japanese-Americans who were affected to compensate for the loss of property. However, the total loss was estimated to be worth up to $400 million. References Schaefer, R. (2008). ââ¬Å"Japanese Americans. â⬠In Racial and Ethnic Groups 11th Edition.

Bowling For Columbine :: Michael Moore Film Review
1. I think media has a great impact on how people behave. The media is defined as listening to music, watching TV, movies, reading magazines, and searching the internet. I think when people here about certain things in songs, or see things in movies or on television it has an effect on them. If there is violence in a TV show or on the news kids can think that's cool to do and do it. A lot of movies show fighting and violence and it effects people and they may do what they see. Television in the home is the greatest source of visual violence for children. Video games expose young children to a level of violence unimaginable. The news also creates fear . 2. I agree with Michael Moore's message in the documentary. I think there is way to much violence in our society, I also think there should be a restriction on guns. Children in our society today, see violence in their schools, on TV , their neighborhoods, and their homes. The daily new is rife with reports of child molestations and abductions. War in foreign lands along with daily reports of murder, rape and robberies also heighten a child's perception of potential violence. 3. I don't think the documentary was biased at all . I think Michael Moore showed both to sides every story he told about . He focused on both sides of the story rather than just one. 4. The NRA Civil Rights Defense fund was established by the NRA board of directors in 1978 to become involved in court cases establishing legal precedents in favor of gun owners. To accomplish this the fund provides legal and financial assistance to selected individuals and organizations defending their right to keep and bear arms. 5. I do not think it was appropriate fir the NRA to arrive in Denver for a convention after the Columbine massacre occurred. I think people were still in mourning and alls they wanted was to be left alone. The people in Denver probably wanted nothing but to ban guns, and here comes the N R A thinking everyone should have the right to have a gun in order to protect themselves. I think the N R A should have waited a great deal of time before going to Denver for a convention. 6. States with the largest increases in gun ownership also have the largest drops in violent crimes.

Scheduling Manufacturing Operations
ABSTRACT Without true finite capacity scheduling, any implementation for manufacturing execution, whether it is ERP, SCM, or MES, cannot realize the goal of enterprise efficiency and agility. All aspects of OM for manufacturing execution fall behind the lead of FCS, which is the bridge between planning and execution. Real tangible return on assets rests with FCS. INTRODUCTION Integrating a diverse collection of resources to accomplish a goal is an issue that has faced humankind since the first city arose and food and services needed to be provided to the populace.The modern challenge for operations management (OM) is the speed and volume that data is presented to OM systems. This explosion of data holds the promise of efficiency and agility unrealized in the past, but it forces the attention of analysts and engineers to convert the flood of data into a useable form to move from planning to action. All the systems such as MES, SCM, and ERP are information hungry beasts that must be fe d with the right information at the right time to direct enterprise resources. OM requires a well-coordinated dispatch of its resources to realize efficiency and agility.This paper addresses the need to look at OM from an information-centric perspective as a necessary complement to emerging process-centric views. This discussion moves to the execution systems, also treated from an information-centric perspective, and concludes with a discussion as to why finite capacity scheduling (FCS) is the key to OM for manufacturing execution. WHEN DATA BECOMES INFORMATION Despite the advances in information technology, notably object-oriented software, systems continue to be defined by functional decomposition.Functional decomposition creates complex definitions with fragile coupling and cohesion that are on one side of a great chasm from the reality of the methods that are used to build modern information systems. Information itself is an under designed component of modern systems. Informatio n is a series of objects made from atoms of data. Data becomes information only through context and inferences derived from context. A good example is the use of spreadsheets to attempt to understand data rather than the use of application software designed to with the operational context in mind. Figure 1: Hierarchy of Data Fusion InferencesFigure 1 shows the hierarchy of inferences through a process called data fusion. Data fusion simulates the cognitive processes used by humans to continuously integrate data from their senses to make inferences about the external world. Information systems collect data though sensors and other assets, and in the hierarchy of data processing, multiple data sources are combined to approximate or estimate the condition of some aspect of the enterprise operation. This is the first translation of data to a level of inference. Parametric data is processed to begin specific identification of a situation.As more parametric data are collected, different a spects of the situation come together to allow a contextual analysis of an increasingly complex set of conditions. Once integrated, the situation can be compared to the goals or desired state of the system. Parallel to the types of data processing are the types of inference. With raw data an inference can be made of the general condition. While this level of inference rarely points to a specific correction action, it does begin to isolate what subsystems require attention. The next level of inference will reveal a specific characteristic behavior of the system.With more integrated data, the identity of an operational system or process is revealed. The next inference is the behavior of a process, which then leads to an assessment of a situation. At the highest levels of inference, the performance is assessed to determine the deviation from the performance goals, acceptable risks, or desired state. Data fusion is not a new concept, having its origins in simple scouting, but has come i nto its own since WWII. The use of data fusion systems as an information springboard for systems design places execution aspects of OM firmly into a modern framework of information systems engineering.WHAT WAS OLD IS NEW AGAIN As mentioned in the introduction, operations management has been, and remains, one of the greatest organizational challenges throughout history. OM arises from the need to coordinate diverse resources to meet the needs of a complex system. The concept of the plan-execute-control model, a ââ¬Å"discoveryâ⬠made by analysts in the late 1990ââ¬â¢s, appears in the historical records of systems management, one of the earliest mentions circa 4th century BC in China. One of the more versatile models in modern systems management appeared in 1977 as a result of a joint effort between Dr J.S. Lawson of the Naval Electronic Systems Command and Dr. Paul Moore of the Naval Postgraduate School. Figure 2 shows the Lawson-Moore model, adapted by the author for genera l resource management. SENSE is the collection of raw data or other collateral information about the observed environment. PROCESS takes the data through the inference hierarchy, integrating data within the context of the tasks required of the managed resources. The situation as best can be determined with the resources is then compared to the DESIRED STATE.The DESIRED STATE is the result of planning, which drives the allocation of resources to tasks. The plan exists in generalities, except for enterprises where goals are achieved with simple tasks assigned to few or uncomplicated resources. DECIDE is the point where the comparison of the situation to the goals will dictate what corrective actions are needed to bring the performance of the enterprise in line with the plan. ACT is the direct management of resources to alter enterprise performance to close the gap between the current state and the DESIRED STATE.The Lawson-Moore model is a closed-loop execution model, continuously inte grating data, making inferences about the environment, and managing resources to meet goals of the plan. The Lawson-Moore model does not address planning, but it does unite planning and execution. To develop an execution system, it is important to understand the distinction between planning and execution. Figure 2: Lawson-Moore Model (aka Lawson Model) PLANNING AND EXECUTION Planning and execution are related, but not one and the same.Planning does not occur during execution; the plan should be formulated to allow for variations and alternate execution strategies. Business (or manufacturing or service) processes are set in place, serving as doctrine that unites actions within the enterprise. Processes should be compiled for all resource management, and serve as a set of procedures designed to achieve the best results from a united enterprise, while allowing for inspired actions and initiatives. The enterprise doctrine exists so that laborious planning for each individual operation n eed not repeated with every new plan.The more complex or unstable composition of enterprise resource, the greater the need for standardized procedures. This becomes the foundation of repeatable performance, reducing human variations to the least contributor of performance variations. Planning cannot deviate greatly from doctrine, and execution will fail without doctrine. It is possible that execution will look so different from the plan that the uninitiated will see no similarity, but if the goals of the plan are achieved, then the execution is successful.The next section will unite the inference model with the Lawson-Moore model to develop an information-centric execution model. DATA FUSION AS OPERATIONS MANAGEMENT SYSTEM Figure 3 shows the execution system that arises from merging inference and the Lawson-Moore model. For main components exist in this system: information collection, execution environment, human-machine interface (HMI), and evaluation. Information collection includ es sensors and all other information gathering, and is a critical component to the resources managed by the OM system.The HMI is the primary means by which operators interact with the OM system. Evaluation is the component that applies performance measurements and other measures of effectiveness to determine the degree to which the execution system is meeting the goals of the plan. The execution system performs the data fusion, situation definition, and resource management. Figure 3: Data Fusion as Execution Environment Data flows from sensors contained in resources through data filtering to begin building inferences. Filtered data enters three levels of information processing.Level 1 processing aligns data in time, insures consistent units of measure, and accounts for any other physical aspects of the data. Data from different sources are aligned or correlated in order to develop meaningful inferences (e. g the color of the box has little to do with its volume, but its height, leng th, and width has a direct bearing on computing volume). The final function of Level 1 is identifying the situation for further processing in Levels 2 and 3. Level 2 assesses the situation within the context of the fusion process in use and available information from Level 1.Level 2 may require algorithms to augment sparse or missing data. Level 3 evaluates the situation and may direct actions to modify the use of resources to minimize deviations from plan goals. The communications between the three processing levels is continuous, forming an information loop within the execution environment to adapt to changes in the external environment. Short term and long term (historical) databases form the decision support system for the OM system. Corrective action can be automatic or require operator intervention as dictated by operation procedures.THE COMMON DENOMINATOR The integrated systems view for the enterprise is emerging as analysts focus on process-centric models and away from produ ct- and information-centric models. Evidence is the REPAC model from AMR, shown in Figure 4. Recognizing the shortcomings of the functions intense MES and SCOR models, AMR developed a model that is focused on the business processes while supporting component assembly. Comparing that process-centric model with the information-centric model, common elements emerge.The main theme in REPAC COORDINATE is the need to schedule detailed activities from PLAN, utilizing feedbacks from EXECUTE and ANALYZE. These are the same themes addressed by the Lawson-Moore model. In both models, the key element is the ability to manage resources at the individual operations to achieve the goals set by the plan. This level of resource management is achieved by dynamic capacitated scheduling, supported by the real-time data from the environment and comparisons to the desired state established by the plan. Figure 4: AMR REPAC Model FCS: THE KEY TO OPERATIONS MANAGEMENTWhether OM is approached from a process- or information-centric model, finite capacity scheduling drives how resources are deployed to perform the tasks required to achieve the goals of the plan. The sequence of operations, the materials and labor required for operations, and the output of the operations all require supporting resources to act in sync with the business of implementing the plan. Finite capacity scheduling with the ability to account for multiple resource constraints and complex scheduling goals will be scalable to schedule both the lowest level of operation and the supporting resources.Planning is at best an approximation of the resource needs because planning cannot develop a precise quantification of labor, material, or time to meet the goals. Execution cannot begin until the set of actions, well matched to the available resources, is developed to load the operations and develop a timeline for the actions. Execution cannot continue unless the scheduling component can receive the feedback from the resourc es and develop alternative sets of actions that will best meet the goals of the plan.Only true finite capacity scheduling, design for real-time use, can integrate the planning and execution together to meet the enterprise objectives. CONCLUSION For manufacturing OM to achieve the goals of efficiency and agility, all aspect of planning, execution, and control are necessary to create an effective system. The bridge from the plan to the actions of the organization is dynamic resource management. For an organization with any degree of complexity, procedures need to be in place to establish the general guidelines of operations. In this imperfect world, the plan and procedures must be flexible enough to adapt.The control side provides data and accepts corrective action, but a dynamic element must exist in the OM system that allows for accepting a situation assessment and rapid response to degrading performance. The planning side requires feedback from the OM layer to create future plans. The baseline provided by planning drives the selection of enterprise operations, but the synchronization of these operations, and the alternative actions needed when the exceptions arise, comes from the power of true finite capacity scheduling. FCS is the means by which OM for manufacturing execution becomes a reality.
