Plan de producción para la optimización de recursos en una empresa artesanal de calzado

Abstract

The main objective of this research is to detail a proposed production plan in the artisanal footwear company Dy'Frans in Ambato city, in order to optimize resources and propose more profitable production strategies, using tools such as aggregate planning, master production plan (MPS) and production requirement plan (MRP). The project begins with a bibliographic search for topics of interest within production planning and tools related to industrial engineering for the evaluation and determination of the initial state of the company. Subsequently, we proceed with the calculation of the demand forecasts that are the basis for determining the production plan that best suits the company. The aggregate production plan corresponds to the first planning tool, which allowed evaluating seven production methods that can be implemented in the company, thus demonstrating that leveling capacity through overtime and variable workforce in the months with greater demand is the type of production that generates the lowest cost to the company. Within the proposal there is also the master production plan, the same one that assigns weekly units to be elaborated either in ordinary time and overtime. In addition, the handling of the quantity to be produced is determined by the lot-by-lot (LFL) rule. Finally, in the material requirement plan, most of the elements for the production of the 8084 model are shared in all its series with exception of the boxes, soles, pins and eyelets. For this reason, the MRP was prepared with 41 codes corresponding to materials and subunits of the shoe, resulting in a final cost of $ 13,299.70 that includes preparation costs, costs for supplier orders and immediate purchases, and costs for maintaining inventories.
