Discrete time-cost tradeoff with a novel hybrid meta-heuristic

In this paper, we present a new hybrid meta-heuristic (HMH) technique for solving multiobjective discrete time-cost tradeoff (TCT) problem in project scheduling. The proposed technique hybridizes a multiobjective genetic algorithm and simulated annealing, and is apposite for problems where generation of complete Pareto front, a TCT curve in this case, is essential for a decision-maker. Discrete TCT problem is known to be NP-hard. We solved two test problems of discrete TCT using HMH-on comparing the Pareto front results of HMH with those of analytical method, HMH performs well in terms of efficiency and accuracy
