Operations Research RIU Test

Lesson number 1.

Question No. 1. What categories of methods for analyzing empirical data are there?
1) heuristic and algorithmic;
2) mathematical and statistical;
3) graphic and analytical.

Question No. 2. What is the essence of a systematic approach to research?
1) dividing a complex task into easier ones;
2) reducing the problem to a standard one by simplifying it or by removing some factors from consideration;
3) deliberate expansion of the conditions of the problem until all the essential relationships are not taken into account.

Question No. 3. What are the distinguishing features of operations research as a science?
1) a systematic approach, a mixed composition of scientific groups, a scientific method;
2) system analysis, observation and experiment;
3) scientific team, scientific method, scientific approach.

Question # 4. At what stages of the “ideal decision” scheme are operations research methods applied?
1) identifying the problem and collecting empirical data;
2) numerical assessment of various possible solutions to the problem;
3) making a decision and putting it into effect.

Question No. 5. The main purpose of operations research is:
1) offering various solutions;
2) calculation of the efficiency indicator and construction of a mathematical model;
3) numerical evaluation of each possible option and identification of the optimal one.

Question number 6. What is the essence of the concept: "mixed team"?
1) uniting people of different age categories;
2) uniting people with different levels of education;
3) uniting people with different professional backgrounds.

Question No. 7. What historical event caused the active development of operations research as a scientific discipline?
1) the development of a market economy in Europe;
2) World War II;
3) the development of applied mathematics.

Question # 8. Choose a false judgment:
1) in the event that the researcher cannot influence the course of the process that is investigating, the observation method is applied;
2) in the case when the researcher can plan the process that is investigating, and even change its course, use the experimental method;
3) observation is used to test the truth of a hypothesis or a causal relationship between phenomena.

Question No. 9. What is the essence of the scientific method in research work?
1) the application of a set of methods generally accepted in a particular science;
2) the application of the methods proposed by the head of the research group;
3) the application of deductive reasoning in the processing of empirical data.
