工程分包JIT采购均衡优化法及在矿业中应用

Optimization of project subcontract JIT procurement with a Nash equilibrium model and its application in mining project

为解决工程分包JIT采购买卖双方利益的均衡最大化问题,研究了工程分包JIT采购过程中买卖双方的博弈机理。建立了工程分包JIT采购的博弈论模型,确定了工程分包JIT采购博弈效用函数,给出了求解工程分包JIT采购博弈模型的均衡优化算法。结合煤矿工程分包JIT采购进行了应用分析,得出了买卖双方利益均衡最大化的数值解,结果表明模型和算法都有效和准确。

To solve the problem of equilibrium benefit maximization of both seller and buyer in project subcontract just-in-time （JIT） procurement, the game mechanism in project subcontract just-in-time （JIT） procurement is proposed. Based on the game mechanism, a complete information dynamic game model for equilibrium optimization of project subcontract JIT procurement was built. The payoff functions for the model were determined according to the benefits and costs of both the seller and the buyer. A sub game perfect Nash equilibrium algorithm for optimization of JIT procurement is given. The model and the algorithm were used in mining project subcontract JIT procurement and the result indicates the model and the algorithm are effective and accurate.
