针对工程建设中工期优化问题,构建了立足于工程全生命周期角度的业主与承包商的收益共享谈判模型.设置了谈判双方均具有公平关切、仅业主具有公平关切、仅承包商具有公平关切三种实验情景,研究了主体公平关切程度对谈判可行域、谈判成功结果、谈判效率等方面的影响.实验结果表明:谈判双方的公平关切程度越高,谈判成功的可行域越小;主体适度提高公平关切程度,会导致工期优化幅度较大,但过度关注公平会导致双方成本大幅增长,不利于系统利润增长;主体不同的公平关切程度会对自身收益产生不同影响;双方保持适度公平关切能够提高谈判成功率,缩短谈判周期. In view of the optimization of construction period, this paper constructs a revenue sharing negotiation model based on the project life cycle perspective between owners and contractors. Both negotiation parties have fair concerns, only owners have fair concerns and only contractors have fair concerns The experiment results show that the higher the fairness concerns of both parties, the less feasible the negotiation is, the more moderate the subject is The level of fairness concerns will result in a large optimization period, but excessive attention to fairness will lead to a substantial increase in the costs of both parties, which will be detrimental to profit growth of the system. Different levels of fairness concern will have different impacts on their own earnings. Both parties will maintain fair and equitable concerns Negotiation success rate, shorten the negotiation cycle.
