A multi-criteria decision-making (MCDM) framework for prioritizing damaged infrastructure and services facilities in Egypt using sustainability objectives

摘要

This paper presents a multi-criteria decision-making (MCDM) framework that identifies and prioritizes significantly damaged Egyptian infrastructure and services facilities-after the January 2011 revolution-using sustainability objectives. First, literature review and interviews with key experts are conducted to develop taxonomy of infrastructure and services facilities' sustainability objectives that could be applied to Egypt. Second, a questionnaire-based survey solicited experts' opinions in rating the sustainability objectives based on their relative importance to the public, using a five-point Likert rating scale. The analytical hierarchical process (AHP) in MCDM is used to determine a relative importance weight factor of each expert, which incorporates the quality of experts in the prioritization process of each sustainability objective. The relative importance index (Rll) method is adapted to prioritize the sustainability objectives based on the rating scores assigned by experts, and their relative importance weight factors. Third, structured interviews with government officials and examination of damaged facilities' database helped in developing a comprehensive list of damaged facilities. Finally, a pilot survey was conducted that enabled experts to prioritize the damaged facilities relative to the sustainability objectives, using a five-point Likert scale; and a crisp facility sustainability priority index (FSPI) is computed using a weighted sum technique in MCDM that determines the priority of repair of each damaged facility. The decision-making framework presented in this paper offers a simple yet efficient evaluation technique to decision-makers with limited budgets that accounts for sustainability objectives in deciding on the repair priorities of damaged facilities.
