Analysis on the Procurement Cost of Construction Supply Chain based on Evolutionary Game Theory

The selection of building materials plays an important role in the control of engineering projects. The subject of this paper is to study the problem of balancing the relationship between the general contractor and building material suppliers in the construction supply chain. Firstly, to solve the problem, this paper from the perspective of material quality safety analyzes the problems between material suppliers and construction general contractor. Then, under the constraints of information asymmetry and bounded rationality, the evolutionary game model of material suppliers and construction contractors is constructed to study the strategy selection in the process of product quality supervision. Finally, the system simulation is carried out by using MATLAB software to demonstrate the evolutionary equilibrium strategy of the model when different parameters change. The results show that the strategy selection of material suppliers and construction contractors is affected by multiple factors such as supervision cost, material cost, risk probability of accident occurrence and penalty amount.
