A multi‐criteria approach to contractor selection

Abstract

This paper describes a multiple-criteria decision support system (MCDSS) for the selection of the most appropriate contractor. The system can accommodate the unique characteristics of a project in addition to the quali®cations and capabilities of those contractors assessed. The system ®rst evaluates the list of contractors by matching their quali®cations with speci®c project conditions. A short list of eligible contractors is thus selected and further the MCDSS compares the current capabilities of the short listed contractors and their plans for the project under consideration, to select the most appropriate contractor.The Delphi method was used to evoke expertise and obtain reliable assessment values for all criteria related to the contractor quali®cation, while the analytic hierarchy process (AHP) was used to assess the speci®c project conditions. The system can be easily modi®ed to adopt speci®c conditions of the proposed project and also to facilitate the decision maker in explaining the reasons for the elimination of excluded contractor.

Designing for construction procurement: an integrated Decision Support System for Building Information Modelling

“…DSS have been developed and used for procurement decisions and even Public private partnership (PPP) strategies (Shalaby and Hassanein, 2019). Any decision-making for procurement or selection process has been of multi-criteria nature (Mahdi et al , 2002; Semaan and Salem, 2017). Therefore, identification and inclusion of the correct criteria, and parties involved are key for such DSS developments.…”

“…Initially the necessities of DSS for construction procurement were investigated through review of relevant literature form well respected sources. The literature search is the extension of previous work on construction procurement literature and focuses on decision-making tools Designing for construction procurement in particular (Jelodar et al, 2016a(Jelodar et al, , 2016bMahdi et al, 2002;Semaan and Salem, 2017;Shalaby and Hassanein, 2019). As the problem is multicriteria in nature, the literature findings focus on decisions types and corresponding criteria (Cheung and Suen, 2002;Zopounidis and Doumpos, 2017).…”

“…In addition, supplier and crew selection normally involves a range of quantitative and qualitative factors (Sanayei et al , 2008). Many factors and multiple criteria need to be considered for informed decisions in construction (Mahdi et al , 2002; Zhao et al , 2016). Tools which can assist this complex decision-making process genially known as Decision Support System (DSS) are gaining popularity (Cavalcante et al , 2017; Shalaby and Hassanein, 2019).…”

Ranked generic criteria for EPC contractor selection

“…Increasingly used in construction management research, the Delphi method is a structured communication technique originally developed as a systematic, interactive forecasting method that relies on a panel of experts answering questionnaires in consecutive Rounds until convergence, with the facilitator providing a summary of their judgments to the group in the form of the mean or median response in each Round: as uncertainties arise from the judgments of decision makers, this method accounts for interpersonal uncertainty and variability in one's opinion (Martin & Ramjarrie, 2021). Of particular relevance here is the increasing use of the Delphi method in such construction management research as graduate education (Pathuri et al, 2020), company performance (Mansour et al, 2020) and contract administration (Gunduz & Elsherbeny, 2020), as well as contractor selection (Mahdi et al, 2002), in terms of performance criteria (Gunasekara et al, 2021), safety criteria (Gharedaghi & Omidvari, 2019), public contract criteria (Hajek et al, 2017), effectiveness factors (criteria) (Lajimi et al, 2018), construction supply chain pre-qualification and selection criteria (Mahamadu et al, 2017), and project source criteria (Faraji et al, 2020).…”

Sustainable Winner Determination for Public-Private Partnership Infrastructure Projects in Multi-Attribute Reverse Auctions

“…This section identifies bid evaluation attributes for the selection of sustainable PPP project contractors by MARAs, based on the literature review and interviews with experts in PPP procurement. The bid evaluation attributes involved in the MARA can be categorized into three types: technical attributes (e.g., Mahdi et al [43]; Yasamis et al [44]), business attributes (e.g., Gao et al [23]), and sustainability attributes (e.g., Ugwu et al [31]; Rahman et al [45]), which represent a contractor's technical competency, business strength, and sustainable responsibility, respectively. All the three kinds of attributes are very important.…”
