Grouped Multi-Attribute Bid Evaluation Decision Method Based on Difference Degree of Experts Scoring

Abstract

With the development of information technology and the strong promotion of Internet Plus, online centralized procurement has been increasingly used by the government and enterprise groups, the design of the winning bid evaluation decision-making method is particularly important. During the multi-attribute bid evaluation decision, due to the strong negative correlation between technical attributes and business attributes, the bid evaluation process may bring irrational influence and opportunistic behavior under the premise of the accumulation of experience and bounded rationality of bid evaluation experts. Considering the unfair decision of experts in the bid evaluation process, this paper proposes a method to determine the attribute weights based on difference degree of the scoring, and the weight between groups is determined according to the scoring similarity. Finally, the effectiveness and applicability of this method are verified by an example, which provides some decision guidance for the centralized procurement.
