Using simulation to solve design and operational problems

One of the most challenging problems facing industrial engineers concerns the design and operational planning of today’s sophisticated production systems. The need for a detailed quantitative analysis is far more apparent than ever before. The application of discrete-event simulation has been growing rapidly in the analysis of production systems. This is because no other quantitative methods can provide the flexibility, realism and predictive accuracy offered by the simulation technique. Although the important role that simulation can play in analysing production systems has now been generally realised, its use is not necessarily straightforward. The successful implementation of simulation projects usually depends on several factors which include, inter alia, the availability of simulation expertise and the ability of the available simulation software to model readily and accurately the environment under consideration. The areas of production systems where simulation can be applied are outlined. The essential considerations which must be studied when applying simulation are also discussed. An overview of simulation modelling environments that are currently used is then taken. Recommendations for future work of importance from the system analysis viewpoint are highlighted.
