SCP和APS智能排程系统之间的主要区别是，SCP更多的是一种管理手段为了整体供应链的决策，而APS是一旦战略重点已经确定，用于详细的系统优化。 SCP是聚焦模拟各种管理优先效应的工具; APS智能排程系统是广泛用于计划和控制的工具。 SCP的管理供应渠道的限制，找到最佳的成本，与主要供应商提供安全沟通，形成整个供应链的开始和结束一个特设的基础网络。 APS智能排程系统的重点是详细工厂级的约束，通过多工厂和同步与工作负荷能力。当然，这些系统有很大的重叠功能。

Advanced tools and analytical applications help planning at all levels but are generally tightly focused rather than broad. The advanced tools covered here are supply chain planning (SCP) and advance planning and optimization/scheduling (APS).
The key difference between SCP and APS is that the SCP is more of a management tool for making holistic supply chain decisions while APS is used for detailed system optimization once those strategic priorities have been set. SCP is a narrowly focused tool for simulating the effect of various management priorities; APS is broad set of planning and control tools. SCP manages supply channel constraints, finds optimal cost, provides secure communication with key suppliers ,and forms networks across the supply chain that can be started and ended on an ad hoc basis. APS addresses granular constraints at the plant level across multiple plants and synchronizes capacity with work load . However ,these system have overlapping functionality, which is covered first.
SCP and APS use analytical applications such as mathematical and heuristic modeling and optimizing techniques and simulations. Both usually include user-friendly planning tools such as interactive scorecards and drag-and-drop functionality in their interfaces. These advanced tools help plan at the strategic, tactical, and operational levels but do not perform transactions themselves.
At the strategic level, these systems perform logistics network design. For a manufacturing company, this would include determining the location of factories, warehouses, and distribution centers, including which aspects of the supply chain will be owned and which will be contracted from a third party.
At the tactical level, supply chain master planning helps optimize production and distribution by maximizing the use of transportation and inventory across the supply chain. Supply chain master planning seeks to maximize profit and minimize cost while taking seasonality, promotions, the competition, capacity, and demand into consideration. The output of the medium- and short-term optimization and simulations becomes the supply chain master plan. This planincludes optimizations for production planning and feeds a detailed sequence of events to the transactional systems, It ensures the availability of materials and capacity and synchronizes their flow. Feedback from these plans helps continuously improve supply chain planning.
At the operational planning level , advanced tools create demand forecasts, demand plans, inventory plan, and transportation plans and help optimize daily production seheduling .These systems remove pressure from bottlenecks in systems as they occur or in simulations. There is a great deal of overlap with these systems and tools such as SCEM. This area also includes collaborative planning, forecasting, and replenishment (CPFR).
-SCV (supply chain visibility) link directly with SCEM(supply chain event management)
-Strategic network design
-Product life cycle management tools
-Resource and materials optimization using business rules
-Simulation using memory-resident technology to provide fast turnaround of results and multiple “what-if” scenarios
-Synchronization of operation
-Finite scheduling (recognizes capacity constraints)
-Dynamic lead time calculation following business rules and compensating for complex systems
-Simultaneous material and capacity consideration to ensure that both are available as needed.
-Penalty management –the cost for using non-optimum routing or equipment.
