MAMCTA Multi-Agent Model for Counter Terrorism Actions

Today, the world is affected by a new concept of war called terrorism. As plans to face conventional enemies have become unusual against terrorism, there are a necessity for innovative concepts and technologies. In order to support units,  we aim to upgrade the capability of leaders structuring their choices. In this paper, we offer a multi-agent architecture for the planning of actions against terrorist attacks. It is distinguished by decisive policy responses and methodical procedures for managing the situation, as well as by the flexibility to adapt a contingency scenario. We describe the relationship between actors during a terrorist attack in order to establish the best possible distribution of units to  neutralize the enemy.

Meta-heuristic algorithms for the multi-item transshipment problem

Differential Evolution (DE) and the Particle Swarm Optimization (PSO) are two evolutionary algorithms that confirmed their efficiency in resolving complex problems. In this paper, we intend to adopt these algorithms to resolve a complex inventory management problem, known in the literature by the transshipment problem.

This problem concerns network of collaborative retailers selling items and they collaborate by exchanging items between them.

The transshipment problem consists in deriving the optimal replenishment
quantity, for each retailer, while a transshipment policy is adopted.

A huge body of literature works has addressed this problem where several configurations are investigated. A few of them has addressed the multi-
item and the multi-location configuration because of its complexity. We focus in this paper on this complex configuration and we resolve it by the PSO and DE algorithms. Secondly, we compare between the performances of these algorithms according to a set of criteria. Thirdly, we analysis the impact of the studied transshipment parameters on the inventory system performance measures.
