模糊多目标规划在制定最优竞标方案中的应用

An Application of the Fuzzy Multi-objective Programming in Optimal Bidding Strategy Design

【目的】针对已有文献提出的一类工程项目的招投标问题,给出了一种使用模糊多目标规划技术进行建模以制定最优竞标方案的方法。【方法】将投标方在利润上的基本目标及招标方所提出的对项目目标的要求作为必须满足的约束来处理,并将最大化投标方所获利润、项目质量等级、安全性能、环境性能,最小化投标方工程成本、项目所需时间作为模型目标函数。【结果】通过对每个目标函数引入分段线性满意度函数,建立了模糊多目标规划模型,并采用加权求和法进行求解。文中给出了具体实例以详细说明建模及求解的过程。【结论】模糊多目标规划技术可以为制定最优竞标方案提供有力工具。

[Purposes]A modeling approach based on fuzzy multi-objective programming techniques is proposed to design the optimal bidding strategy for the bidding problem in view of the existing literature.[Methods]This approach treat the basic objective on profit of the bidder and the project objectives of the tenderee as hard constraints,and set the maximization of profits of the bidder,project quality standard,project safety performance,and the minimization of project cost of the bidder,the project construction time as the objectives of the modelling problem.[Findings]A fuzzy multi-objective programming problem is then formulated by applying apiecewise linear satisfaction function to each of the objective functions.The weighting method is adopted to solve the formulated problem.A concrete example is given to illustrate the modelling and solving process in detail.[Conclusions]The fuzzy multi-objective programming techniques can provide a powerful tool in the optimal bidding strategy design.
