Much is heard today speak of the ERP, but few know where you come from. The ERP began its history originally (Manufacturing Planning and Control MPC) manufacturing planning and Control systems that existed since the early days of the industrial revolution, to automate several tasks and improve accuracy, reliability and predictability of the manufacturing. Then they had greater importance under the heading of point of reordering (ROP), these systems were automated with the introduction of mainframes in the late 1950 and early in 1960 then arrived the MRP that had its origin during the second World War when United States use specialized programs to organize and control the logistics of their units. MRP systems allowed to introduce tools to generate basic computerized production reports, and these were used to evaluate the viability of plans and against forecasted demand. In the years 60-70, MRP systems have evolved to help the companies to reduce their levels of inventories, because at the plan your inputs requirements based on what really demanded them, costs were reduced.
In the early 1980s, Manufacturing Resource Planning systems, changed to MRP II (manufacturing resource planning), these systems developed with management capabilities based on the demand of the MRP, adding the capacity of the planning of requirements (CRP), capabilities to create an integration. MRP and MRP II systems that eventually evolved were characterized by using mainframe computers, hierarchical databases and complex transaction processing systems, adjusting mainly towards the management of a production environment of a few products, with high volumes, under conditions of constant demand. It was in the 1990s when the term ERP (Enterprise Resource Planning) was assigned to these systems. Achieving that the ERP will generate a better degree of horizontal integration of the companies now. ERP systems marked a point significant in the development of the MPC systems since they are enabled to the companies towards the global guideline for continuous improvement of the processes of chain with the suppliers through flexible management with customer.
