摘要
在工程项目竞争性投标中,对于承包商来说,投标决策是一个多风险因素综合评价的问题,既要考虑自身实力,业主情况等主观条件,又要考虑项目的复杂性、自然条件等客观条件,同时还要兼顾经济、社会、环境、安全等各种因素。结合我国当前建设市场的现状和国内外相关文献,构建了工程项目投标风险因素评估系统层次结构和指标体系。针对在多因素指标的综合评价问题上,建立相互独立的指标比较困难和人们的主观评价往往存在非线性的特点,在模糊测度的基础上,提出一种基于Choquet模糊积分的新的工程投标多风险因素综合决策算法,详细论述该算法的计算步骤,并通过案例验证该方法的可行性、有效性和实用性。结果表明,该方法可以对多个项目进行投标风险评估排序,并且计算简单,可适用多种综合评价问题。
In the bidding/tender process of construction projects, bidding decision-making for the contractor consists of comp,＇ehensive evaluation of many factors, not only subjective factors such as owner and self strength, but also objective ones such as project complexity, natural condition, etc., while striking a balance between economic, social, environmental, security, and other various factors. Combining the present situation of the construction market in China and relevant literature, a hierarchical structure index system is established to assess risk factors for bidding of construction projects. To overcome the difficulty in comprehensive environment, and considering that people establishing independent indexes under the multi-factor ＇s subjective evaluations often have nonlinear characteristics, a new tender decision algorithm involving more risk factors based on the Choquet fuzzy integral is presented. The algorithm is described in detail, and the feasibility, effectiveness and practicality are verified via test cases. The results show that the algorithm can be used for tender risk assessment and project ranking, simple to use and applicable to various comprehensive evaluations.
