An objective approach for generating the functional specification of manufacturing planning and control systems

Outlines an objective model based approach for the functional specification of manufacturing planning and control (MPC) systems. It is based on the premise that there is factual information (company characteristics and management concerns) which can be used to make recommendations about suitable functionality of appropriate MPC systems. A generic MPC system architecture, applicable to medium‐sized batch manufacturing companies, is used to organise the information within the model. The model describes the relationships between the inputs (objective company characteristics and subjective management concerns) and outputs (MPC functional activities). The functional activities have been defined at a level of detail which represents significant choices in functionality and are useful for the functional specification of MPC systems. The model provides reasoning which describes the relevance of the activities in individual cases. Uses field studies to validate and test the elements of the model (inputs, outputs and reasoning). Uses the model output to create an outline functional specification at each of the field study sites. Concludes that the model can be used to obtain an objective view of necessary functionality in MPC systems in medium‐sized batch manufacturing companies. The output from the model can be used as the basis for the development of a final, detailed functional specification. Use of the model results in time savings.
