Supply planning to reduce immobilized inventory in a mining explosives factory

One of the most important problems affecting companies that market explosives is excess inventory in warehouses and powders. The case study is presented in a company CAX S.A Peruvian explosives manufacturer that shows poor comprehensive supply chain planning. This leads to the form and increase of frozen inventory representing 15.6% equivalent to 6,172,436.76 and incurring storage costs, maintenance of inventories and final provisions with a value of 9,605,518.05, due to the following causes: inflated needs, lack of capacity constraints, unreported production orders, unplanned orders, lack of capacity constraints of stock security. All this is due to the main problem that proper comprehensive company planning is not carried out. The solution proposal consists of the application of the SCOR and SOP model, which redesign and configure the supply chain improving performance of the logistics processes. As a general framework the company introduced four stages for the development of SCOR: stage 1 Types of processes, stage 2 Process configuration, stage 3 process decomposition and Development of the SOP. The implementation was carried out by means of a pilot, based on the following indicators at the start of the Pilot Material Rotation (4.5). Inventory coverage (4.5 months), OTIF suppliers (93%), Needs level (94%), ERI (99%) e Fixed inventory ( 6, 172,436.76). At the end of the implementation, which was established within six months, the results were Material Rotation (5), Inventory Coverage (3.5), OTIF providers (94%), level of needs (96%), ERI (99%) and immobilized inventory ( 3, 537,634.10).
