Erp-planning garbage: Realizing and preventing

Abstract

MRP II is still the planning core of most ERP-software systems and practically usage with well known but often ignored weaknesses. These weaknesses and their reasons are described in detail. Most APS are concentrated only on partial planning aspects with insufficient results. Until now all well known OR methods prove as unsuitable to solve the high complex planning ERP tasks for practical use. Rolling Detail Planning (RDP) is an approach, which changes fundamentally ERP-MRP II philosophy. TPS is an innovative alternative software system based on simulation techniques and fuzzy logic by realizing RDP. It claims to avoid the faults of MRP II based software systems and to get over the weaknesses in calculation, concepts, transparency, and cost of OR based APS.
