Soru 11:

The foundation of operations research is mostly cited to studies and applications in the U.S. Army right before The World War II. Leonid V. Kantorovich is recognized as the first to explore operations research area. In 1939, Kantorovich published a paper on a method for a production plan which he claimed to be the optimal way. The systematic solution which is called “simplex algorithm” was introduced by George B. Dantzig, who had planning experience in the U.S. Army Air Force. Tjalling C. Koopmans, who built a model for ship routes, was another contributor to the field. Tjalling C. Koopmans and Kantorovich shared 1975 Nobel Prize in economics for their studies on the optimal allocation of resources. Which of the statements above about the historical development of operations research are correct?

A) I and II B) II, III and IV C) III, IV and V D) I, II, III, V and VI E) I, II, III, IV, V and VI

Soru 12:

Which method is defined as the difference between the optimal and the actual pay-off?

A) Criterion of pessimism B) Criterion of optimism C) Criterion of realism D) Equally likely E) Minimax regret

Soru 13:

A) Only I B) I and II C) II and III D) I, II and III E) I, II, III and IV

Soru 14:

Soru 16:

"An airport ground operations firm seeks to minimize the cost of human resource for its passenger services. The airport runs 7/24 and the number of passengers fluctuates with the time of the day. To maintain the quality of the service, the operations manager keeps the passengers-to-service personnel ratio at a threshold level. Hence the number of personnel needed has to be optimized as the number of passengers change. The personnel works eight successive hours a day only with five-shift schedule starting at 4 a.m., 8 a.m., 12 p.m., 4 p.m. and 8 p.m." The problem given above is an example of which of the following?

A) Manpower planning B) Inventory control C) Production planning D) Nutrition problem E) Agricultural planning

Soru 17:

E1, E2, E3 show the events and A1, A2, A3 show the alternatives. The profit values of each event are given in the table above. Which is the most appropriate decision according to the Equally Likely Method?

A) A1 with 3.33 B) A2 with 5.33 C) A2 with 6.33 D) A3 with 3.67 E) A3 with 5.67

Soru 18:

What is the process of choosing the most appropriate one of the alternatives called?

A) Information B) Number of alternatives C) Objective D) Outcome E) Decision making

Soru 19:
