The problem of multi-criteria decision making under conditions of insufficient information about the importance of criteria is considered in the paper. To solve this problem, a modification of the COPRAS method (complex proportional estimation) is proposed, which includes interval weights and introduces the concept of a fuzzy COPRAS solution. To demonstrate the application of the approach, an example of choosing a steam boiler is solved.

摘要

The problem of multi-criteria decision making under conditions of insufficient information about the importance of criteria is considered in the paper. To solve this problem, a modification of the COPRAS method (complex proportional estimation) is proposed, which includes interval weights and introduces the concept of a fuzzy COPRAS solution. To demonstrate the application of the approach, an example of choosing a steam boiler is solved.
