Business case study with operational research techniques solution

Thus for resource 1, this would be translated into the following mathematical statement 0. The key here is that O. The planning problem is very complex, since different grades of crude yield different concentrations of output streams and incur different costs, and since different end-products fetch different revenues and use different amounts of refinery resources.

Case Studies

The distinguishing feature of a heuristic technique is that it is one that does not guarantee that the best solution will be found, but at the same time is not as complex as an optimum-seeking technique. The studies had to do with improving the operational efficiency of systems an objective which is still one of the cornerstones of modern O.

On the other hand, there is also evidence to suggest that unfortunately the criticisms leveled against O. The bottom line is that an O. What is the least number of games that must be played to find a tournament winner?

How many light bulbs are there in the United States? The decision-maker then selects the combination of values for the decision variables that yields the most desirable performance.

This mathematical program tries to maximize the profit as a function of the production quantities G and Wwhile ensuring that these quantities are such that the corresponding production is feasible with the resources available.

Typically, the team will have a leader and be constituted of members from various functional areas or departments that will be affected by or have an effect upon the problem at hand.

Knowing where to draw such a line is precisely what determines a good modeler, and this is something that can only come with experience.

On the other hand, this comes with a price; these systems are also very complex and the process of planning and scheduling production on an FMS and then controlling its operation can be a very difficult one. Please provide the total weight of a fully loaded Jumbo Jet at the time of take off.

A model may be defined formally as a selective abstraction of reality. To illustrate how the steps might be applied, consider a typical scenario where a manufacturing company is planning production for the upcoming month. As some background, the distillation of crude petroleum produces a number of different products at different distillation temperatures.

Given the new diversity of product lines and the tremendous increase in the complexity of production planning, Harris was having a hard time meeting delivery schedules and in staying competitive from a financial perspective; clearly, a better system was required.

It was also determined that minimizing the makespan which is the time required to produce all daily requirements would be the best objective since this would also maximize as well as balance machine utilization.

In the orientation phase, the team typically meets several times to discuss all of the issues involved and to arrive at a focus on the critical ones. Examples include a globe, a scale-model car or a model of a flow line made with elements from a toy construction set.

Simulation models are extremely powerful and have one highly desirable feature: Such a problem can be solved efficiently by using techniques from network flow analysis. An assumption that might be made here is that all of the units produced can be sold.

From your initial review of the case information you determine the main parameters to consider are total revenues and total costs. Case building continues when the case builder proposes specific actions to address these objectives.

Case Study Interview Examples: Questions and Answers

Data typically comes from two sources — observation and standards. The final estimate would probably represent a compromise between the two that is acceptable to most team members.

At minimum you'll need to perform some basic arithmetic or mathematical calculations. Interviewers asking case study questions are primarily concerned with how effectively you can analyze a problem, determine key factors, brainstorm ideas, and propose workable, pragmatic solutions that are supported by your analysis.

How would you recommend the company address this problem? The other option is to use a technique designed specifically for multiple objectives such as goal programming.
