PRODUCTION PLANNING AND CONTROL IN TEXTILE-INDUSTRY - A CASE-STUDY

This paper presents an interactive model based system for the manageme nt of production in textile production systems focusing on the Master Production Scheduling problem. Because of the special characteristics of the industry, that is mainly the multi-phase process with multiple units per phase, different planning horizons and different production requirements for each phase, the scheduling of these systems becomes q uite complex. Apart from a comprehensive presentation of the set of th e modules the system is composed of, together with their interrelation ships, the above characteristics are analyzed, and their impact on the production control system is explained. The system is also related to two well-known production control systems, namely MRP-II and Optimise d Production Technology. The system's attributes are presented with th e aid of data structure diagrams, while the complete algorithm concern ing the Master Production Scheduling module, in a pseudo-code form, an d the corresponding part of the database are illustrated in Appendix A .
