One of the main problems attracted researchers' attentions in recent years is Vehicle Routing Problem (VRP). This paper tends to minimize the covered distance, total travelling time, number of vehicles, delay and transportation costs, and to maximize consumers' satisfaction by utilizing...

We develop a hybrid algorithm using Genetic Algorithms (GA) and Simulated Annealing (SA) to solve multi-objective step function maximization problems. We then apply the algorithm to a specific economic problem which is taken out of the corporate governance literature. -- numerical computation ;...
