Manufacturing adapter of distributed simulation systems using HLA

In this research, a distributed simulation system to easily evaluate a very large manufacturing system by synchronizing several different simulators is developed. We designed the distributed simulation system using the High Level Architecture (HLA) as the IEEE1516 standard. A manufacturing adapter to connect manufacturing system simulators with HLA using a plug-in style is proposed. The developed distributed simulation system is confirmed using a case to evaluate a hypothetical manufacturing system which produces motors. Three major commercial based manufacturing system simulators, QUEST, SIMPLE++, and GAROPS, are connected using the developed manufacturing adapter. The storage model method to connect simulation models and synchronize the simulators is used in the case study. A case study is then carried out to evaluate the performance of the cooperative work.

The development of an object-oriented simulation system based on the thought process of the manufacturing system design

The purpose of this research is to develop an integrated evaluation environment for manufacturing system designs. In this paper, we analyzed the thought process of manufacturing system design, and proposed a manufacturing system model for planning and evaluation by using a thought process model. The model evaluates a manufacturing systems design from the abstracted design phase to the detailed design. Finally, a prototype system for simulation using an object-oriented methodology was developed and implemented for a flow shop type manufacturing system design applying the proposed simulation model.
