Evaluation of safety-based performance in construction projects with neutrosophic data envelopment analysis

Abstract

PurposeThe main purpose of this paper is to create a suitable structure based on neutrosophic numbers to evaluate the safety performance in construction projects in such a way that the shortcomings can be highlighted with the reasoned measurement and possible strategies can be recommended.Design/methodology/approachData envelopment analysis (DEA), which is a useful tool for performance appraisal, along with neutrosophic logic, which is one of the most complete tools for handling uncertainty phenomenon, has been used to evaluate the safety performance of construction projects. With this hybrid model, a new strategy is considered as an indicator for safety performance and comparisons are made between different units.FindingsA total of 35 Chinese organizations with construction projects lasting between 1.5 and 2 years were selected for comparison. After processing the data into neutrosophic numbers and using the NN-DEA model, it can be found that projects that pay more attention to safety issues such as training and equipment are more efficient.Originality/valueSince in the real world, there are uncertainties with different contradictions, and neutrosophical data can handle many of these challenges, using DEA model with neutrosophic numbers to evaluate the performance of construction projects from a safety perspective, can provide significantly better results. Therefore, considering that no study has been presented in this field so far, the authors will deal with this topic.

Guest editorial: Preface to the special issue on the neutrosophical approach: applications in management decision and organizational research methods

“…NN consists of a crisp parameter and a value with a literal indeterminacy parameter (I), and can explain the restricted confident and restricted indeterminate information using formula A 5 a þ bI. To evaluate the safety performance in building projects, Li et al (2023) suggested a framework based on the combination of data envelopment analysis (DEA) and NN to expose deficiencies with the rational measurement and recommend possible strategies. This hybrid model evaluates a new approach as an indicator of safety performance, and several units are compared.…”

“…The new concepts of IVFNG are employed to find the best materials that are used for making dental implants in the case of smokers. There are many researchers developed and studied different types uncertainty sets and their application in Multi-Criteria Decision-Making (MCDM) (Duran et al, 2021;Ejegwa et al 2022;Mohanta et al, 2020;Li et al, 2022;Smarandache, 2020;Smarandache, 2022;Wang et al, 2022;Zhang et al, 2022). Mahesh et al (2022), made a comparative study Author Contributions: Conceptualization, S.B and F.S; methodology, S.B., M.T., and A.B; software, R.S.…”

Evaluation and Analysis of Land Input-Output Comprehensive Benefit Based on Fuzzy Mathematics and Analytic Hierarchy Process

“…With the development of evaluation methods, some combinatorial evaluation methods based on fuzzy mathematics are applied more successfully [30][31][32]. This paper intends to combine the analytic hierarchy process, particle swarm optimization algorithm, and fuzzy mathematics comprehensive evaluation method, through the subjective and objective mutual combination of methods, a comprehensive evaluation of the comprehensive benefits of the land.…”
