Autorzy podkreślają potrzebę systemowego podejścia do zarządzania produkcją. Prezentują rozwiązanie w postaci komputerowego systemu, obejmującego projektowanie technologii, planowanie produkcji, monitorowanie, pomiar procesu i wyrobu, weryfikację planów, analizę danych dla potrzeb podejmowania decyzji. Komentowana jest metodyka planowania oraz struktura i tabele baz danych.

The paper presents computer aided production process management system in metal processing business developed by a team of technologies, computer scientists, automatics, and specialists in management working in Mechanical Working and Theory of Metals Department. The most important conditions of construction, implementation and maintenance of the System have been described. It is highlighted that the System: - provides coherent, transparent, complex, standard based management of production, which reduces probability of erroneous operational and strategic decisions, - allows reliable appraisal of processes and their results, - based on relevant models and available operational data implements a process control loop: production preparation - planning of material flow and resources - supervision of performance (monitoring and measuring of processes and products) - evaluation of results and verification of plans, - integrates the existing local solutions, if needed, - is especially useful in compound production systems in metal processing business, - ensures optimization of internal solutions, upgrades effectiveness and rationalises the use of resources and increases production abilities. Planning related problems in compound production systems have been identified. The need of description of quasi-continuous system has been mentioned. Production campaigns in particular elements of the line are organized in this system, and sequence of production units is imposed. A design of System database has been described. Constant and variable data have been mentioned. Principles of collection and verification of constant technological, planning related data including limitations and parameters of the models have been given. Variable data of the System are included in tables of orders (e.g. requirements) and in monitoring results. An example of implementation in a car body sheet rolling mill with extremely complex production system. Conditions for implementation of tube production and processing have been described.
