At present most of the scheduling software on the market provides a scheduling tool for enterprise planners, only helping planners gradually decompose and deal with single-level problems,and cannot really establish an efficient planning system for enterprises from the dimension of the upper system. SAPS can be a high-level supply chain planning system. In the process of transforming an enterprise from a single company to a group company, the cooperation of multi region, multi factory, multi department, multi country and upstream and downstream supply chains makes the original relatively loose supply chain structure change to a tight supply chain network alliance.SAPS covers the long and short-term plans of all activities in the whole supply chain, from procurement, transportation, production, distribution to customer demand.
