This paper aims to show how the proposed approach (two analytic hierarchy process [AHP] models) may allow dealing with the best tender selection process in an organic and simple way and ensure the consistency check of the judgements, the necessary step for having reliable results. At first, this paper highlights some critical issues regarding the weighted sum model (WSM) and the algorithms frequently used to evaluate the most economic advantageous tender. Then, it proposes to extend the AHP approach to the evaluation of both the qualitative and quantitative components of a public procurement award. Finally, the WSM and the AHP are applied to the same case study to show, step by step, some criticisms of the former and some advantages of the latter.,This paper proposes to apply two AHP models to evaluate both qualitative and quantitative components of a public tender. The quality and cost models allow to identify and select the tender associated with the highest quality/cost ratio.,The assessment of the WSM and the AHP models, and some differences between them, build upon their application as an example of public procurement. A case study is used as a teaching device (Yin, 2003) to highlight why the AHP may provide different results. In particular, an important issue concerning the evaluation of qualitative requirements is explored: the consistency of judgements expressed by the committee members.,This approach provides analytical tools for public management that allow appropriate implementation of their management function and allow a realisation of the strategic objectives of European Union law and Italian legislation on public procurement. It would help managers to prioritise their goals and criteria and evaluate them in a scientific way. The model integrates multiple qualitative and quantitative criteria, simplifies the selection process, achieves optimal use of funds and leads to cost savings. It allows to reduce the discretional power of both the contracting issuer, in the choice of the formula to adopt for calculating the coefficients, and the committee members, allowing tender evaluation to have more trust and ensure the fairness of public procurement matters and quality of the object purchased.,This paper proposes the use of two hierarchical models to evaluate qualitative and quantitative requirements and provide the ranking among several tenders.

多标准方法选择最具经济优势的投标

本文旨在说明所提出的方法（两个层次分析法[AHP]模型）如何能够以一种有机且简单的方式处理最佳投标选择过程，并确保对判断的一致性检查，这是获得可靠结果的必要步骤。首先，本文重点介绍了有关加权和模型（WSM）以及经常用于评估最经济有利投标的算法的一些关键问题。然后，它提议将AHP方法扩展到对公共采购奖励的定性和定量组成部分的评估。最后，将WSM和AHP应用于同一案例研究，以逐步展示对前者的一些批评和对后者的一些优势。本文建议应用两种层次分析法模型来评估公开招标的定性和定量组成部分。质量和成本模型允许识别和选择与最高质量/成本比率相关的投标。WSM和AHP模型的评估以及它们之间的一些差异，建立在它们作为公共采购示例的基础上。案例研究被用作教学手段（Yin，2003），以突出为何AHP可能会提供不同的结果。特别是，探讨了有关质量要求评估的一个重要问题：委员会成员表达的判断的一致性。这种方法为公共管理提供了分析工具，使他们能够适当地执行其管理职能，并实现欧洲联盟法律和意大利关于公共采购的立法的战略目标。这将有助于管理人员确定其目标和标准的优先次序，并以科学的方式对其进行评估。该模型集成了多个定性和定量标准，简化了选择过程，实现了资金的最佳利用并节省了成本。它可以降低签约发行人在选择用于计算系数的公式和委员会成员时的酌处权，从而使招标评估获得更多信任，并确保公共采购事项的公平性和质量。购买的物品。，
