Solving Dynamic Resource Allocation Problem Using Decentralised Multi-agent Systems
Date: 19 Jan 2009 - 19 Jan 2009
Venue: Training Room 1, SIMTech Tower Block, Level 3
Dynamic Resource Allocation Management (DRAM) has been conceived to specifically deal with situational developments in the production shop floor. It is perceived as a supplement to manufacturing execution systems to respond effectively to any unplanned shop floor events that are disruptive to the production schedule. DRAM problem is a very complex NP (Non Polynomial) issue with many variations, particularly when it takes place in a dynamic environment. Multi-agent system is a good approach to solve dynamic allocation problem. A decentralised multi-agent system designed for dynamic resource allocation problems will be presented in two parts, namely (i) Agents Movement System and (ii) Agents Management System.
The Agents Movement System is used to govern the movement of agents and manipulates the task scheduling and workload equalising among machines. A hybrid 'Roam-Space' movements of the decentralised multi-agent system will be discussed. The Agent Management System is proposed to handle dynamic events and provide an environment for agents' negotiation. This presentation will introduce a new dynamic resource allocation problem that considers machine degradation. Based on the proposed decentralised multi-agent system, simulation results from a number of case studies for different types of resource allocation problems will also be discussed.
