The Value of Queueing Theory—A Case Study

The case study described here was carried out in 1971 to supplement a 20-hour introductory course on OR methodology and techniques which was organized within a large Greek company. The specific problem to be studied was chosen by the plant manager in the major factory of the company, the one engaged in the manufacture of electrical appliances, and it involved the study of the operation of the internal transport system.

It appeared that the study had two major objectives to meet: (a) to educate the participants of the course on how a real world problem could be analyzed and formulated in terms of a model, and (b) to assist in resolving the conflict within the plant by providing quantitative information on the advantages and disadvantages of increasing the size of the fleet. Senior management regarded the study as an opportunity to enhance the spirit of team work within the company and backed it with their full support.
