This paper deals with two bi-objective models arising from competitive location problems. The first model simultaneously intends to maximize market share and to minimize cost. The second one aims to maximize both profit and the profit margin. We study some of the related properties of the...

This paper proposes an approach for setting parameters of the control of balance by card-based navigation (Cobacabana). On the one hand, a commercial software ARENA was used in a simulation phase. On the other hand, Antcoba was utilised in an optimisation phase. The main objective of the paper...

We propose an algorithm to optimise a sum of products of revenue and credit information in TV advertising. This algorithm exploits the credit information of the advertiser and the ant colony system. To evaluate the performance of the algorithm proposed in this research, we conduct numerical...
