The invention provides a multi-attribute automobile evaluation decision-making method and a multi-attribute automobile evaluation decision-making system considering index conflicts and dispersion, andrelates to the technical field of multi-attribute decision-making. According to the multi-attribute automobile evaluation decision-making method, two dimensions are fully combined on the basis of considering the index evaluation grade utility difference expressed by confidence distribution, a new method for determining index weights is disclosed, and the index weights can be determined more comprehensively and reasonably, so that an obtained evaluation numerical value sequence of an automobile social life cycle evaluation scheme is more accurate, the selected automobile social life cycle evaluation scheme conforms to the reality, and the decision cost of a decision maker is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of multi-attribute decision-making, in particular to a multi-attribute vehicle evaluation decision-making method and system considering index conflict and dispersion. Background technique [0002] The multi-attribute decision-making problem is a very common problem in real life, which widely exists in many fields such as complex product social life cycle evaluation, medical quality evaluation and enterprise management decision-making. [0003] At present, the weight of indicators is usually taken into account when making multi-attribute decision-making. For example, when evaluating the life cycle of automobile society, the CRITIC method is used to consider the standard deviation of indicators and the degree of conflict between indicators to determine indicators based on the obtained evaluation values of numerical indicators. Then use evaluation methods such as evidence reasoning, TOPSIS, etc. to fuse indic...
