Synthetic Evaluation on Decision of Public Bidding for Construction Project

Public bidding is the international current practice to contract construction project. But the decision on the bidding often is made according to the qualitative evaluation based on the subjective opinion of specialists. Therefore, the fuzzy mathematics principle was applied and a synthetic evaluation model was established to provide an effective method for the development of quantitative bidding decision in this paper.

A Grey Decision Model Used in Bidding for Equipment Purchase

Bidding has long been used as a method for allocating and procuring goods and services. An acurrate and comprehensive evaluation of bidders is the key to make the bidding a successful one for tenderee. However, evaluation of bidders is a tough work and the result of evaluation is always affected by the evaluator's understanding of the standards set for evaluation, and the evaluator's expertise, experience and preferrence. We make an effort to find a method for selecting bidders as accurately as possible. A grey decision model is presented, and an example is illustrated to make the practioners know how to use the model.

This paper not only improved the tendering and bidding stage method of cost control in construction project in our country, and improves the method system of engineering cost control.

Research and Application of FAHP in Bidding Quotation for Petroleum Geophysical Prospecting Project

This paper mainly talks about the main layer analytical method, and fuzzy comprehensive evaluation, fuzzy hierarchical analysis (AHP) method of a deeper connotation, and further discusses its application in bidding quotation for petroleum geophysical prospecting project. Fuzzy analytic hierarchy process (FAHP) integrates many merits of AHP and fuzzy comprehensive evaluation organically. It determines the weight of each affecting factor using analytic hierarchy process at first, and then uses the fuzzy comprehensive evaluation method to determine each scheme index. FAHP can effectively enhance the decision-making efficiency.

Detection Tool for Unbalanced Bids

Unbalanced bidding is a cash flow management strategy that is recognized as an illegal/disqualifying practice by public owners;and unethical practice by most private owners. This practice provides the awarded bidder with unjustified advantages at the expense of the owner. Unfortunately, limited tools and techniques are currently available to identify and detect unbalanced bids during the evaluation process. This paper presents an innovative detection tool to identify unbalanced bids in unit price contracts during the bid evaluation process. The proposed technique develops BMDI graphs to visualize total markup variation patterns during the project lifetime to detect unbalanced bids. The proposed method also uses Monte Carlo simulation to take in consideration the impact of cost uncertainties and risks. An illustrative example was presented to show the capabilities and features of the proposed method in determining the status of submitted bids during the evaluation process.

Applying Fuzzy Matter-Element Model Based on AHP to Evaluating Bids of Water Saving Irrigation Project

Owing to overcoming the characteristics that there are many economic and technical indexes which are fuzzy and incompatibility to each other in evaluating investment project,a new method is proposed.The method is based on the matter-element analysis and combined with the concepts of fuzzy mathematics,which is called the method of fuzzy matter-element analysis.It constructs the compound fuzzy matter element with the investment projects,evaluation factors and their fuzzy value.Through establishing the best subjection degree (fuzzy value),complex fuzzy matter element of relational coefficient and weight aggregation of fuzzy matter-element model,the writer achieves on optimum order of the investment projects according to the calculated relational degree and finds the best project.In this paper,the calculation of weight adopts the analytical hierarchy process method(AHP).Through the actual example,it shows that the model is simple and its calculation is reliable.It is very significant for the engineering evaluated bid and investment decision.

Determining winner in multi-attribute procurement auction:a method based on technical and business experts' evaluation information

A method for solving the winner determination problem （WDP） in multi-attribute procurement auctions is proposed, based on technical and business experts＇ evaluation information. Firstly, on the background of procurements in China, a multi-attribute pro- curement auction mechanism is presented, where technical and business experts participate in the bid evaluation. Then, the concept of TOPSIS is used to determine the positive and negative ideal points of the WDP according to bid prices, the technical and business experts＇ evaluation information. Further, the closeness coefficient of each bidder （candidate supplier） is obtained by calculating the distances to the positive and negative ideal points. Thus, the winning supplier can be determined according to the closeness coefficients. Finally, a numerical example is used to illustrate the use of the proposed method.

高职院校推进全面从严治党在制度机制、“四风”问题、科研项目、招标采购等方面存在诸多问题。这需要省委、省纪委监委继续深化高职院校纪检监察体制改革,需要高职院校党委、纪委立足全面从严治党“两个责任”,从完善制度机制、巩固作风建设成效、强化科研项目监督、严格招标采购管理等方面综合施策、协同发力,从而更好地发挥党建引领高职教育发展效能,进一步营造风清气正的政治生态和干事创业的育人环境。

“最低评标价法”之探析

“最低评标价法”是一种国际通行的评标方式,旨在通过合理的价格竞争选择最优投标方案。然而,在我国的实践中,该方法经历多次修改,逐渐偏离初衷,导致最低投标报价与最低价中标二者概念混淆,非价格因素与评标逻辑冲突,从而影响了政府采购的公正与效率。本文明确区分“评标价”与“投标报价”,建立科学的评标体系,设计合理的评标标准,确保价格因素与非价格因素之间的平衡,以规范最低评标价法在政府采购中的应用。

论解决政府采购评委成员意见分歧的思考

政府采购过程是一个很长的链条,政府采购的最终结果,往往取决于评审结果,而评审结果又依赖于评标委员会成员意见。在实际评审中,评委成员难免出现意见不一情形,现行处理分歧的法规没有明确或相互冲突,为推进评审进程,实践中有些公共资源交易中心简单地采取多数决规则解决评委成员间关于共同认定事项的意见分歧,但是多数决规则有着诸多局限,并非所有意见分歧都能通过多数决方式解决,有必要重新界定多数决规则在评审中适用边界和适用规则。
