DETAILED PLANNING IN A MILK POWDER FACTORY A CSP MODELLING APPROACH
In this paper we will focus on the modelling aspect. We will identify and discuss important and obvious modelling choices, which are usually encountered when designing an object oriented constraint based model for a real world planning situation. For illustrating purposes we will construct several models of a milk powder factory. This factory has many characteristics that are relevant in food industry, which is the broader scope of our research.
In the second section we will describe the factory, products that are made and processes that take place. In the third section we will describe the input of the detailed planning system and the desirable outputs. Various modelling choices and possible consequences are discussed in section four. The last section outlines the results of implementing the models using ILOG tools.
