Abstract

The invention discloses a multi-party decision-making credible method based on an evolutionary game in an industrial internet environment. The method comprises the following steps: constructing a decision model to obtain utility values of decision participants; calculating a parameter rho according to the utility value before and after the strategy is changed, and determining whether to change the strategy according to the parameter rho; according to the strategies of all the decision-making participants, whether overall strategy selection of the decision-making participants reaches an equilibrium state and an evolution stable proportion state or not is judged in sequence, and if the overall strategy selection reaches the evolution stable proportion state, it is indicated that credible multi-party decisions in the industrial internet environment have been achieved. According to the invention, a reputation mechanism is designed according to the game theory, and the reputation mechanism can seriously influence the utility value of the decision participant. When selecting a selfish strategy, a decision participant is seriously punished, the benefit of the decision participant is seriously lost, the decision participant is afraid of dishonesty, and the decision participant can consciously select a cooperation strategy to honesty submit decision data, so that multiple decision participants in the industrial internet can mutually trust, and the credibility of multiple decisions in the industrial internet environment is ensured.

Description

technical field [0001] The invention belongs to the technical field of industrial Internet, and in particular relates to a multi-party decision-making credible method based on evolutionary game in the industrial Internet environment. Background technique [0002] As an important cornerstone of the fourth industrial revolution, the Industrial Internet has flourished in many industries, enabling efficient communication and industrial intelligence between multiple parties. With the development of the industrial Internet, it has exposed problems in product traceability and multi-party trust. The blockchain records data such as transactions and communications in the network in a tamper-proof and completely orderly manner. It has the characteristics of decentralization, tamper-proof and traceability. Therefore, it has developed rapidly in the field of industrial Internet in recent years. Good applications provide a premise guarantee for traceability in the Industrial Internet, bu...
