Faced with possible events in the future,policy makers often do not have sufficient information materials for investment programs to limit their ability to understand,lack a deep understanding of the various natural conditions of future events,complicated and changeable environmental factors,and the complexity of decision makers for decision-making.Subjective factors(subjective randomness is the most important factor),timeliness,etc.directly affect the decision-makers to make decisions correctly.For example,when people buy clothes,they will generally consider the following five factors: the color of clothes,clothes,The style,the quality of the clothes,the size of the clothes,the price of the clothes,this is a decision problem with five goals.Another example is the consideration of subsequent planning and management in the study of water resources systems。There are four general objectives to be considered: the economic aspect,the location of the local development,the quality of the environment,and social welfare.More complex systems,such as economic and social development systems,energy systems,and ecological and environmental systems,will require more inspections.In these complex decision-making tasks,different decision makers may choose different criteria to make decisions on the same uncertain decision-making problem,which may lead to different results.It is not surprising that there are some mistakes.Based on these factors,how to make decisions that are full,accurate,reasonable,effective,and timely is especially important for decision makers.It is particularly important to study the theory and methods of multi-objective decision-making problems and their application in practice。The existing literature usually divides decision-making issues into three categories: deterministic decision-making,risk-based decision-making and uncertain decision-making.This article introduces the current criteria for uncertain decision making and the applicable scenarios for each criterion.For example,the optimism criterion is a kind of extreme assumption.Only the best returns of each scheme are considered.The decision-makers are too optimistic about the future development of the decision.In the process of decision-making,this is often accompanied by loss as a cost..The compromise rule needs to take into account its optimism factor,as well as the two extreme states of the best and worst states of the decision.The consequence of this is that it is easy to ignore other relevant information of the decision matrix,and at the same time its optimism coefficient It is difficult to determine and there is a lot of people subjective.This paper studies the existing methods for solving multi-objective decision making.The easy-to-know nature of certain decision elements in the process of finding the optimal solution to a decision problem.In the known multi-objective decision-making criteria,the relative effectiveness analysis decision-making criterion is proposed as a method for solving a certain class of decision-making problems.The methods such as least-squares method,linear programming,and most-likelihood solution are used to optimize and apply them.Simulation test in Java program.
