Implications of Formal Production Information Systems for Production Management

Production systems are becoming more and more information intensive activities. Production management is faced with new challenges which demand an overall information approach to production information systems planning. However, production systems are not all alike. Each system presents different information implications for system selection and operation. An information systems view of production information systems is offered. The analysis is based on principles central to systems thinking in general, with specific reference to production systems. Various such systems, including hierarchical, MRP, JIT, OPT and FMS, are then examined from a major aspect of systems design, the concept of system guarantors. Each of these systems has proved successful in certain production environments. However, from an information systems point of view, the question is not always one of net return or claims of increased productivity, but rather who or what will in the final analysis guarantee the system's results.
