Sorting Subcontractors’ Activities in Construction Projects With a Novel Additive-Veto Sorting Approach

Abstract

Selection processes in civil engineering infrastructure projects might require more time and effort than the decisionmakers involved in these projects are normally prepared to devote to running them. A novel approach is proposed to sort these activities into classes that represent their impact on the project, namely additive-veto sorting model, which should be considered before any bidding procedure. Therefore, problems regarding the client’s satisfaction caused by subcontractors can be avoided, and the decision-makers involved in the selection problem can devote to each class an effort compatible with the impact that activity might have on the project. The novelty of this method is that it was built to reflect the quasi-compensatory rationality of decision-makers in the construction industry; it provides them with insights on subcontractors’ activities, and it is grounded on and inspired by a real case study. The new parameters proposed within this model introduce the idea of vetoing an activity being assigned to a class when this activity is incompatible with the decision-maker’s preferences. By using this novel method, the authors succeeded in finding results that avoided a complete compensation amongst the factors considered, taking into account ranges that would be of significant importance in the decision process.

Pythagorean Fuzzy AHP Based Dynamic Subcontractor Management Framework

“…Koçak et al [17] have adopted an approach to create a new alternative to SC selection with the Additive Ratio Assessment Method, which is one of the multi-criteria decision-making (MCDM) techniques that can be more scientific, instead of traditional practices in the construction industry. Palha et al [18] have developed a method for pre-tender selection based on a real case study that provides insight into the activities of SCs. El-khalek et al [19] aims to identify, analyze and prioritize the most important criteria affecting the SC selection process using the statistical analysis approach.…”

Uma Proposta Para Priorização De Projetos No Contexto De Uma Instituição Federal De Ensino Superior

“…A priorização de projetos é uma atividade complexa considerando a existência de múltiplos critérios de avaliação e as possíveis combinações de alternativas a serem priorizadas, podendo ser realizada através de um processo de escolha, ranking, classificação de prioridade ou portfólio (PALHA et al, 2019). Em outras situações, como apresentado por Palha (2019), este processo pode envolver além da seleção de alternativas através de múltiplos critérios, a compatibilização de vários decisores.…”
