2. Methodology

The process of developing the proposed methodology (Fig. 1) begins by setting up and gathering the required information related to form the project scheduling network diagram. Furthermore, the multiple modes of each activity must be determined considering the unavoidable constraints viz. the resource limitation and the resource usage plans, technology limitations, various construction methods, etc. Duration (time), as well as the cost and quality of each activity can be quantified. The MOGA with NSGA-II procedure is tailored to guide the algorithm to converge the global Pareto optimal front. Each objective (e.g., time, cost, and quality) will have different relative normalized weights. These can be obtained using the Shannon’s entropy technique. In order to relate the aforementioned objectives to the overall performance criterion, a hierarchical structure can be developed with associated computed weights to show how the overall performance can be evaluated. In subsequent steps, the ER approach helps DMs evaluate each alternative (Pareto solutions), assign overall utility scores indicative of their degree of satisfaction with each alternative, while considering all criteria simultaneously. Eventually, the Pareto solution with the highest corresponding utility score is selected as the best solution.
