2. Editor of research object: Operational research mainly studies the planning and management problems that can be expressed quantitatively in economic activities and military activities. Of course, with the development of objective reality, many contents of operational research not only study economic and military activities, but also go deep into daily life. Operations research can get various results through mathematical analysis and operation according to the requirements of the problem, and finally put forward comprehensive and reasonable arrangements to achieve the best results.
3. Historical Origin Editor: As a modern science, operational research was first developed in Britain and America during the Second World War. Some scholars describe operational research as a scientific means to make decisions on various operations of organizational systems. P.M. Morse and G.E. kimball define operational research as: "Operational research is an applied science, which uses mathematical methods to make overall planning and decision on problems that need to be managed in the management field." Another founder of operations research defines operations research as "a scientific method that people who manage systems must use in order to obtain the optimal solution about system operation." It uses many mathematical tools and logical judgment methods to study the organization and management, planning and scheduling of people, money and things in the system. In order to maximize the benefits.
4. Editor of subject characteristics: 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; Operational research not only carries out 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. 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.
5. Editing of research methods: extracting essential elements from real life situations to build mathematical models, so as to seek solutions related to decision makers' goals; Explore the structure of the solution and deduce the solution process of the system; Seek the optimal solution of the system from the feasible scheme.
