In which of the areas above operations research applications, particularly linear programming, are now used as a standard method for decision making?

If the objective is minimization which product is the right choice according to minimax regret method?

Which of the following is a feasible solution to this linear program: "Minimize Z=x+3y subject to the constraints: y ≤ 2x, x+y ≤ 10, x ≥ 0, y ≥ 0.

If decision maker has a pessimistic approach, the Criterion of Pessimism can be used. According to this criterion, the decision maker thinks that the ------- outcome for each alternative will be realized.

"Linear programming is only effective if the model you use reflects the real world."

Which of the following is not a common characteristics of decision making?

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

Which of the following is the end process of the decision making?

1. The foundation of operations research is mostly cited to studies and applications in the U.S. Army right before The World War II.
2. Leonid V. Kantorovich is recognized as the first to explore operations research area.
3. In 1939, Kantorovich published a paper on a method for a production plan which he claimed to be the optimal way.
4. 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.
5. Tjalling C. Koopmans, who built a model for ship routes, was another contributor to the field.
6. 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?

1. In the minimization models, the objective function is alternatively named profit function.
2. The ultimate goal of minimizing something is to reduce loss or “cost”.
3. In the minimization models, a line is drawn parallel to the objective function and near to the origin.
4. This line should contain at least one point of the feasible region.
5. The coordinates of this point are found by solving the equations of the drawn line and the boundary line(s) of the feasible region.
