Documentation of discrete event simulation models for manufacturing system life cycle simulation

The concept of life cycle simulation appeals to most production engineers. There is a problem with simulation models of manufacturing systems; they may be highly complex and time consuming to develop. They embrace a considerable experience, which is gained through the development process of the simulation model. It is therefore not enough to develop an accurate simulation model. The model must be understood, updated, re-used and adhered to by others. One way to achieve these goals could be through use of a standardised documentation, which in turn explains the model and how it has been developed. This paper presents a method for the way in which simulation models can be documented by standardised notations. The documentation is adapted to different users of the simulation model.

1 Introduction

The concept of life cycle simulation appeals to most production engineers, A manufacturing system has a life cycle, precisely as a product has its lifecycle. Normally the life cycle of the manufacturing system is much longer than the product life cycle. During its life the manufacturing system will go through a number of changes. The changes can be driven by various reasons: •

Introduction of a new product

•

Rationalization of the production

•

Changed legal provisions…
