【摘要】 本文在已有时差概念分析的基础上,提出了三个新时差概念,给出了同一工序不同时差关系,提出了标值算法,算出了不同工序时差传递量。对资源均衡优化问题的初始方案进行研究,给出了随机时标网络图的绘制方式,使网络技术的应用更具灵活性和实用性。在时差传递性的基础上,进一步对有资源限制的资源均衡优化方案进行研究,提出了基于赋值算法的优化调整方式,最后通过算例对该调整方式进行了验证。更多还原

【Abstract】 Based on the analysis of activity floats existed,three new concepts of float are proposed,intrinsic relation of the same activity’s float is offered,and label algorithm is given,moreover,float’s transitivity of different activities is computed.In allusion to the initial scheme of the problem of resource leveling,we protract the initial scheme stochastically.It is flexible and applicable for network planning.On the basis of activity float transitivity,the optimal scheme of the resource leveling problem is studied.Furthermore,considering the label algorithm,the proposed optimal adjusting mode is feasible and easy through example.更多还原
