Material requirements planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software-based, but it is possible to conduct MRP by hand as well. An MRP system is intended to simultaneously meet three objectives:
Manufacturing resource planning (MRP II) [1] is a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning, and has a simulation capability to answer " what-if " questions and is an extension of closed-loop MRP (Material Requirements Planning).
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]
Meanwhile, in the sixties, a different approach was developed by George W. Plossl and Oliver W. Wight, [27] this approach was continued by Joseph Orlicky as a response to the TOYOTA Manufacturing Program which led to material requirements planning (MRP) at IBM, latter gaining momentum in 1972 when the American Production and Inventory Control ...
A critical factor in production planning is "the accurate estimation of the productive capacity of available resources, yet this is one of the most difficult tasks to perform well". [7] Production planning should always take "into account material availability, resource availability and knowledge of future demand". [5]
The Gartner Group first used the acronym ERP in the 1990s [8] [9] to include the capabilities of material requirements planning (MRP), and the later manufacturing resource planning (MRP II), [10] [11] as well as computer-integrated manufacturing. Without replacing these terms, ERP came to represent a larger whole that reflected the evolution of ...
QRM criticizes commonly used material planning and scheduling systems such as Material Requirements Planning (MRP), Manufacturing resource planning (MRP II), and Enterprise resource planning (ERP) for not incorporating system dynamics in their analysis and not accounting for the cost of long lead times. [22]
