Abstract


Multi Agent Based system (MAS) is a technology that has become more popular in E-manufacturing and is being used in a wide range of control applications including scheduling and planning. It enables a manufacturing company to be highly flexible, agile, and versatile.  In the paper a MAS is used to allocate parts to machines in a company with high excessive stock in which work in progress is accumulating in between work stations with an aim of improving scheduling of jobs, utilisation of machines and production throughput. The MAS was developed using Multi Agent System Engineering (MASE) methodology with Analytical Hierarchy Process (AHP) used to develop the decision making model for best machine selection. Each machine was assigned priority value according to time, cost and quality as the decision criteria for determining the best machine to perform the intended operation. Java Agent Development Environment (JADE) was used for the deployment of agents. Simulation of the existing production set up shows that the proposed MAS model will reduce the lead time of developing work order by 83%, machine utilisation is increased from 73% to 84% and prioritization of machines is increased from 0.193 using a human expert to 0.197 using the MAS.
