Operational research is an important professional basic course of modern management. It is a new discipline developed in the early 1930s. Its main purpose is to provide scientific basis for managers' decision-making, and it is one of the important methods to realize effective management, correct decision-making and modern management. This subject is applied to the interdisciplinary research of mathematics and formal science, and uses statistics, mathematical models and algorithms to find the best or near-best solution to complex problems. Operational research is often used to solve complex problems in real life, especially to improve or optimize the efficiency of existing systems. The basic knowledge of operational research includes real analysis, matrix theory, stochastic process, discrete mathematics and algorithm basis. Application, mostly related to warehousing, logistics, algorithms and other fields. Therefore, operational research is related to applied mathematics, industrial engineering, computer science, economic management and other majors.
1, operational research has been widely used in the overall coordination of industrial and commercial enterprises, military departments, civil affairs and other research institutions, so its application is not limited by industries and departments.
2. Operational research not only conducts creative scientific research on various operations, but also involves the actual management of organizations. It has strong practicability, and should eventually provide constructive suggestions to decision makers and receive practical results.
3. It aims at overall optimization, and tries to solve the conflict of interests among all departments of the system in the best way from the perspective of the system. It can be regarded as an optimization technology to find the optimal solution and the best action plan for the studied problem, which provides an optimization method to solve various problems.
