Using Electimize to Solve the Time-Cost-Tradeoff Problem in Construction Engineering
Construction optimization problems are difficult to solve due to the enormous number of parameters resulting from the booming in technology and the application of sophisticated systems in construction projects. In the past few decades, evolutionary algorithms (EAs) have served as good optimization techniques for solving these problems. However, many EAs are limited in their capabilities in reaching optimality due to their methods of evaluating candidate solution strings. This paper presents a newly developed evolutionary algorithm, named Electimize, with an application example on solving construction time-cost-tradeoff problem (TCTP). The new algorithm simulates the behavior of electrons moving through electric circuit branches with the least resistance. Specifically, the paper discusses: 1) the basic steps of optimization using Electimize, 2) TCTP modeling using Electimize, and 3) comparison between performances of Electimize and other EAs used to solve this problem. Electimize demonstrates an advantage over other existing evolutionary algorithms in the method used for evaluating solution strings, which is reflected by the better results obtained for the TCTP.
