Integrated Modeling and Application of Standardized Data Schema

Application of discrete event simulation has been widely accepted in the manufacturing industry forshop floor capacity and flow analysis. Often the models are made to analyse a limited aspects ofthe system behaviour that abstract only few factors for the sake of simplicity in the expense ofmodel accuracy. One of the prohibitive reasons for a detailed and multi objective model is thecollection and management of the input output simulation data.In this work an integrated and detailed simulation model of a machining line has been built for thepurpose of a multi objective analysis and optimization with application of thestandard simulation data schema for data management. The model incorporates detailed capacityand flow related factors as well as sustainability factors (energy usage in machine tools), Theabstraction level of the model is sufficiently low to capture the effect of operators’ movements inthe shop floor and setup procedures. To support modeling of such a detailed model enhancemodel reusability, the Core Manufacturing Simulation Data standard XML schema was used. Thisneutral format of data will also help to build model with less effort, reuse the information, andcommunicate with different application tools. A case study is carried out to illustrate the methodsand run a multi objective optimization. The results of the optimization work are reported in anotherpaper.
