Next Generation Supply Management Defined
Basic aspects

The end phase of an OR study is to implement the system as agreed by the management. The completion of this phase depends on the assistance of both top management and operating management. Mostly students are not finding core concept and good materials for operation research subject and topics, We at TutorsGlobe prepare world class study materials and provide you freely on web.

Our tutors are working for students giving those benefits of higher education teaching experience. Get solved problem just in time by professionals and compare yourself, you will get easy to solve same kind of problems in future. Start Excelling in your courses, Ask an Expert and get answers for your homework and assignments!! Defining the problem and collecting data 2. Creating a mathematical model 3.

Obtaining solutions from the model 4. Checking the model and its solutions 5. Preparing to execute the model 6. Defining the problem and collecting data The first job is to analyze the relevant system and formulate a well-defined statement for the problem.

This comprises determining appropriate objectives, interrelationships, limitations and alternative course of action. The OR team generally works in an advisory capacity. The team carries out a thorough technical analysis of the problem and then provides suggestions and recommendations to the management.

Ascertaining the appropriate objectives is a highly significant aspect of problem definition. Some of the objectives contain maintaining stable price, increasing the share in market, profits, enhancing work morale etc. OR team normally spends large amount of time in collecting important data. To get precise understanding of problem To give input for next phase.

OR teams' takes use of Data mining methods to find large databases for interesting patterns that may direct to useful decisions.

Creating a mathematical model This phase is to recreate the problem in mathematical symbols and expressions. Objective function - It is a measure of performance profit which is expressed as mathematical function of decision variables.

Optimization The solution of the model gives the values of the decision variables that maximize or minimize the value of the objective function and also satisfying all the constraints of that particular system.

Example Maximize the gain of the production oriented company. Minimize the losses of the trading company. The advanntages of using mathematical models are - Explain the problem in brief Makes whole structure of problem understandable Provide help to reveal significant cause-and-effect relationships Mentions clearly about what additional data are relevant for analysis Creates a bridge to use mathematical technique in computers to examine 3.

Obtaining solutions from the model This phase is to create a process for deriving solutions to the problem. To find the solution, the OR team uses Heuristic procedure which is a designed procedure and does not guarantee an optimal solution is used to get a good suboptimal solution. Metaheuristics which provides both general structure and strategy guidelines for developing a precise heuristic procedure to fit in a particular kind of problem. Post-Optimality analysis is the analysis done after getting an optimal solution.

It is also known as what-if analysis. It comprises of conducting sensitivity analysis to find out which parameters of the model are most significant in determining the solution.

Checking the model After deriving the solution, it is tested and analyzed as a whole for errors if any. Preparing to execute the model After the ending of testing phase, the next step is to implement a well-documented system for practically implementing the model.

Final Execution or Implementation The end phase of an OR study is to implement the system as agreed by the management. Deriving Solution from the Model 4. Testing the Model and the Solution Derived from it 5. Establishing Controls over the Solution 6.

Implementation of the Solution. Quantitative basis for decision making is provided to managers by O. Operation research, like a scientific research is based on scientific methodology which involves following steps. In formulating a problem for O.

Out of the above four components environment is most comprehensive as it provides a setting for the remaining three. The operation researcher shall attend conferences, pay visits, send observation and perform research work thus succeeds in getting sufficient data to formulate the problems.

Once the project is approved by the management, the next step is to construct a model for the system under study. The operation researcher can now construct the model to show the relations and interrelations between a cause and effect or between an action and a reaction. Now the aim of operation researcher is to develop a model which enables him to forecast the effect of factors crucial to the solution of given problem.

The proposed model may be tested and modified in order to work under stated environmental constraints. A model may also be modified if the management is not satisfied by its performance. A solution may be extracted form a model either by conducting experiments on it i. No model will work appropriately if the data is not appropriate.

Such information may be available from the results of experiments or from hunches based on experience. The date collection can clearly effect the models output significantly. Operation researcher should not assume that once he has defined his objective and model, he has achieved his aim of solving the problem. The required data collection consumes time to prepare if data collection errors are to be minimized. As has been pointed out earlier a model is never a perfect representation of reality.

Privacy FAQs

In an operational research project there are 5 phases, namely, problem identification, formulating problem, deriving solution validating model and lastly, the implementation of results. The first phase is to identify the problem through the observation of its symptoms if it is not obvious.
