Contractor selection is a crucial aspect of construction projects, with significant impact on project success. However, traditional methods may not effectively handle the complexities and uncertainties involved in decision-making. To address this, advanced techniques like Multi-Criteria Decision-Making (MCDM) have been developed. In this study, we propose new approach based two uncertain method...

This approach has proved to be useful and practical when a decision problem under consideration includes multiple criteria, which are of both a quantitative and qualitative nature. In this type of problem, a major difficulty is how to aggregate numerical data and subjective...

Evaluating contractors’ performance is a multiple attribute decision making process consisting of vagueness and imprecision.

In this paper we propose and test a contracting mechanism, Multi-Contract Cost Sharing (MCCS), for use in the management of a sequence of projects. The mechanism is intended for situations where (1) the contractor knows more about the true costs of various projects than does the contracting agency (adverse selection), and (2) unobservable effort on the part of the contractor may lead to cost re...
