An environment-based methodology to design reactive multi-agent systems for problem solving

Abstract: Even if the multi-agent paradigm has been evolving for fifteen years, the development of concrete methods for problem solving remains a major challenge. This paper focuses on reactive multi-agent systems because they provide interesting properties such as adaptability and robustness. In particular, the role of the environment, which is effectively where the system computes and communicates, is studied. From this analysis a methodology to design or engineer reactive systems is introduced. Our approach is based on the representation of the problem's constraints considered as perturbations to stabilize. Agents are then defined, in the second place, as a means of regulating the perturbations. Finally, the relevancy of our proposition is justified through the development of two solving models applied to real and complex problems.

Multi-agent approach to dynamic pick-up and delivery problem with uncertain knowledge about future transport demands

Abstract: This work focuses on the dynamic Pickup and Delivery Problem with Time Windows (PDPTW) The transport requests should be performed using the available fleet of vehicles The vehicles move between the nodes of a road network The aim of this work is to propose a model which allows, during a transport plan creation, to take into account predictable events Particularly, we consider the frequency of requests at any node in the road network and the construction of vehicle routes that will allow new requests to be inserted without any significant route modification Therefore, we construct routes that pass near the nodes where transport requests are most frequently generated

Porosity content control of CoCrMo and titanium parts by Taguchi method applied to selective laser melting process parameter

Abstract: Purpose – The purpose of this paper consists in the optimization and understanding of the Selective Laser Melting (SLM) manufacturing process of biomaterials, such as T40 and CoCrMo, as scaffolds. Moreover, process optimization is also challenging, with regards to the huge number of parameters and their influence on the finished product. Design/methodology/approach – The paper opted for an exploratory study using Taguchi analysis method to precisely identify the most relevant parameters and justify the energy estimation. Findings – The study showed that SLM fits perfectly with the T40 and CoCrMo part manufacturing. This method allowed to have a complete overview of all the potential applications of SLM for implant manufacturing. Originality/value – With this research approach, the results may be generalized to other material and showed a good theoretical approach.
