COMPARISON OF INFORMATION-SYSTEMS FOR ENGINEER-TO-ORDER AND MAKE-TO-STOCK SITUATIONS

This paper investigates the nature of information systems for the support of production management. It provides a comparison between these information systems in two cases: (i) the case of make-to-stock production; and (ii) the case of engineer-to-order production. Databases with basic product and process information have quite a different nature for these two cases. For make-to-stock production, such as classical MRP systems, the basic information should be complete, consistent and up-to-date. This information is used by planners to generate materials and capacity plans in an automated way. For engineer-to-order production, it should be allowed that basic information is incomplete, partly inconsistent, or not up-to-date. This is due to the fact that these data are used by engineers as reference data for the creation of customer-specific solutions.
