Development of integrated product model for supporting production monitoring system on an automobile assembly industry

Making a good production planning is a first step to produce products in effective and efficient ways. A good production planning needs information about the real conditions in the shop-floor. Without knowing the actual conditions in the shop-floor, it will be difficult to plan production well. In order to know the conditions of the shop-floor, a production monitoring system is needed. This paper deals with development of integrated product model for supporting production monitoring system on an automobile assembly industry. The integration of information between the production controls with the shop-floor is needed to build a production monitoring system. One way to integrate the two systems is by using a product model that is a representation of a real product. In general, the research method used in this research is the development of product models and other related models. The modelling concept used in this research is object oriented modelling. After that, this research also has developed a database in accordance with the developed models and interfaces used to manipulate them. The main proposed models in this research are the product type model and the product model. The product type model is the product model that represents the product designs. On the other hand, the product model is a model that represents the actual products. If the data on the product type model is relatively static, then the data on the product model is dynamic depending on the state of the real product. Each product model will have production sequence processes in accordance with the sequence processes of the represented product. Each time a process of real product is finished, and then the related process model in the product model will be updated. The condition of the processes that has occurred in the shop-floor will be known by manipulating data of the product models
