What is manufacturing resource planning

MRP I included the following three major functionalities: master production scheduling. bill of materials. inventory tracking.

Manufacturing resource planning is defined as 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 extension of closed-loop MRP.

Manufacturing Resource Planning (MRP II) is an integrated information system used by businesses. Manufacturing Resource Planning (MRP II) evolved from early Materials Requirement Planning (MRP) systems by including the integration of additional data, such as employee and financial needs.

The system is designed to centralize, integrate, and process information for effective decision making in scheduling, design engineering, inventory management, and cost control in manufacturing.

Both MRP and MRP II are seen as predecessors to Enterprise resource planning (ERP), which is a process whereby a company, often a manufacturer, manages and integrates the important parts of its business.

An ERP management information system integrates areas such as planning, purchasing, inventory, sales, marketing, finance, and human resources. ERP is most frequently used in the context of software, with many large applications having been developed to help companies implement ERP.

MRP II is a computer-based system that can create detailed production schedules using real-time data to coordinate the arrival of component materials with machine and labor availability. MRP II is used widely by itself, but it's also used as a module of more extensive enterprise resource planning (ERP) systems.

MRP II is an extension of the original materials requirements planning (MRP I) system. Materials requirements planning (MRP) is one of the first software-based integrated information systems designed to improve productivity for businesses.

A materials requirements planning information system is a sales forecast-based system used to schedule raw material deliveries and quantities, given assumptions of machine and labor units required to fulfill a sales forecast.

By the 1980s, manufacturers realized they needed software that could also tie into their accounting systems and forecast inventory requirements. MRP II was provided as a solution, which included this functionality in addition to all the capabilities offered by MRP I.

The answer is true a pertinent question is an appropriate question.
