Outputs may be used to create a Material Requirements Planning (MRP) schedule. A master production schedule may be necessary for organizations to synchronize their operations and become more efficient. An effective MPS ultimately will: Give production, planning, purchasing, and management the information to plan and control manufacturing [3]
A key character of scheduling is the productivity, the relation between quantity of inputs and quantity of output. Key concepts here are: Inputs : Inputs are plant, labour, materials, tooling, energy and a clean environment. Outputs : Outputs are the products produced in factories either for other factories or for the end buyer.
MRP allows for the input of sales forecasts from sales and marketing, or of actual sales demand in the form of customers orders. These demands determine the raw materials demand. MRP and MRPII systems draw on a master production schedule, the breakdown of specific plans for each product on a line.
Output 1 is the "Recommended Production Schedule." This lays out a detailed schedule of the required minimum start and completion dates, with quantities, for each step of the Routing and Bill Of Material required to satisfy the demand from the master production schedule (MPS). Output 2 is the "Recommended Purchasing Schedule."
MES may operate across multiple function areas, for example management of product definitions across the product life-cycle, resource scheduling, order execution and dispatch, production analysis and downtime management for overall equipment effectiveness (OEE), product quality, or materials track and trace.

Productivity is a standard efficiency metric for evaluation of production systems, broadly speaking a ratio between outputs and inputs, and can assume many specific forms, [47] for example: machine productivity, workforce productivity, raw material productivity, warehouse productivity (=inventory turnover). It is also useful to break up ...
The inputs could be: demand plans, sales/demand forecasts, demand impacts, marketing actions and sales actions, procurement and supply plan, supplier lead time, constraints from the supplier and other information, supply capacity, production and capacity plan, Inventory, work-force level, operational constraints, production lead time ...
Scheduling and choosing the actual work to be started in the manufacturing facility" [1] Setting up and delivering production orders to production facilities. [5] In order to develop production plans, the production planner or production planning department needs to work closely together with the marketing department and sales department.
