Material requeriment planning: práticas de implementação em uma empresa de implementos agrícolas

Abstract

The search for cost reduction and efficient usage of resources in the production system requires companies to make a spotless management of their materials, main assets when talking about the production strategies of an organization. Even so, many companies still do not use tools and management techniques that are often simple but still bring great results. The target of this monography is to solve a practical problem of inventory control in a company that manufactures agricultural machinery, the method used is Material Requirements Planning (MRP), using tools such as ABC Analysis, Bill of Materials, Order Point and Inventory Levels. As results obtained, there was an improvement in the potatoes machinery's manufacturing processes, increasing the information efficiency in the sawing process by 73%, reducing the lead time from 2 days to 0,454 days. In the welding processes the lead time decreased from 3 days to 0,963 days, as a result, the final assembly time decreased from 2 days to 0,916 days. This improvement in processes reduced the lead time up to 51% of product manufacturing, which decreased from 8 days to 3,92 days, reducing the total lead time of the product from 32 days to 27,92 days.
