The goal of the thesis was to elaborate a production planning model which would allow to combine all demand sources within one production schedule and to decrease spare parts stock with simultaneous production of identical components (spare parts

The proposed production planning model has been based on the classical stock management theory and material requirement planning methods. It results in merging production management and stock management in a one coherent material flow

The model has been verified through its implementation and resulted in a decrease of spare parts stock by nearly 50%.摘要，本文提出了作者，同时应用规划与生产相同成分的自己的组装需要及在机械工业设备备件的库存补货模型古
5、典模型的生产。该论文的目标是制定生产规划模型，允许在一个结合生产计划，所有的需求来源，并减少与生产相同成分的同时库存备件（零件，组件的自己组装的需要）和备件。拟议的生产规划模型，基于传统库存管理的理论和物料需求计划方法。在合并在一个连贯的物质流管理系统的生产管理和库存管理，它的结果。该研究是在格兰富 POMPY有限公司公司。 RUNDFOS 是世界上最大的泵生产商之一。该模型已核实通过实施该计划和今后一个备件库存减少，导致了近 50。I.

THE ASSUMPTIONS OF THE PRODUCTION PLANNING MODEL:二。生产规划模型的假设：The production planning model with simultaneous production of identical components for the need of own assembly and as spare parts should be

This means that there is a mutual correlation between the method of production and the adopted system of stock replenishment. It is particularly crucial in plants with the developed distribution network of final products. T

The method of material requirement planning is applied to production planning from the moment of generating spare parts requirement in the decoupling point.2) The spare parts demand is treated as independent demand. Repeated production aimed at a diverse group of receivers is assumed. The producer has a limited influence on the final products users, thats why the failure of particular parts take place at random.3) The spare parts stoc
