Investigating Delay Factors in Electrical Installation Projects using Fuzzy TOPSIS

The common objective of most of studies that have investigated causes of project delays was to prioritize delay factors in a specific country by conducting opinion surveys of contractors, clients, and/or consultants using a Likert scale and simple ranking methods ignoring the fact that prioritization of delay factors is a multi-criteria problem that is subject to vagueness and uncertainty. To overcome this limitation, this paper proposes the use of fuzzy TOPSIS. The usefulness of this method is demonstrated by investigating delay factors in electrical installation projects carried out by an organization in the United Arab Emirates.
