Modelo de gestión basado en la metodología DDMRP para el aprovisionamiento de materiales en la industria del calzado

Abstract

EXECUTIVE SUMMARY This study allowed to apply DDMRP methodology in footwear industry, it is based on planning of material requirements based on demand that consists of modeling, pulling and managing entire supply chain in real time, this way of managing resources originates from the growth of organizations since there is greater complexity in planning of material supply, production scheduling and distribution networks. The purpose of the DDMRP is generate synergy of processes around flow of materials and relevant information, focusing all processes on a common objective, the execution of the DDMRP methodology is based on the knowledge of real demand (qualified) , added to the control points such as strategic positioning of buffers, the generation of alerts such as: average physical inventory level that is an indicator that shows amount of stock that organization is willing to manage, out-of-stock alert projected, this indicator shows possible shortages that can be generated and finally management of buffers that visually show their behavior for making timely decisions, with all this congregation of information, the necessary policies were established to manage all the resources of supply chain, with the application of this methodology, emergencies were reduced due to exhaustion and the supply level was improved. A comparison was made between the TOC and DDMRP methodologies, the parameters that were examined are the amount of inventory and the level of turnover, TOC suggests 174, 497 pairs of boots as monthly average inventory, in the case of DDMRP the inventory value recommended is 194,782 pairs of boots, when reviewing the turnover rates there is an obvious difference between the two methodologies.
