New generation APS systems for demanding planning environments
The paper examines strategically important management tool - Advanced Planning and Scheduling systems (APS systems) and their efficiency in Demanding Planning Environment. The key characteristics of Demanding Planning Environments are systematized: the uniqueness of the technological processes; high complexity and scope; limited ability to describe and low predictability; high volatility and change sensitivity. The new generation of APS systems is defined. The comparative analysis of the planning systems of several generations (MRP II, APS I, APS II) is provided. Finally, examples of implementations of the new generation APS systems at Trinicke Zelezarny, Czech Republic; TimkenSteel, USA; VSMPO-AVISMA Corporation, Russia are provided.
