Abstract

This research work details the development of a material requirement plan for a medium-sized company in the textile sector, which is dedicated to the manufacture of underwear for men, women, boys and girls, located in the Santa Rosa parish. , from the province of Tungurahua. Various industrial engineering techniques focused on the field of production planning are applied, such as: time study, calculation of forecasts with trend factor, calculation of production capacity, analysis and calculation of production costs, aggregate planning, a production master plan. Within a structured list of materials, costs for acquisition and supply of material, costs per order and delivery times are involved, information of great importance for the development of an MRP, which has been carried out at three levels, 1) determination of an aggregate production plan through the analysis of three traditional models corresponding to leveling capacity with inventories, matching demand and subcontracting, the latter being the most suitable for the company based on its economic activity, internal capacity, available labor and number of orders by the customer with a cost of $128,980.20, 2) a master production plan, in which the batch size to be produced per week in a period of 3 months is determined and whose feasibility is determined by the capacity requirement calculation and 3) a list of the gross material requirements to cover the monthly demand, resulting in a p issued whose releases consist of exact amount and date. The application of this MRP system allows greater coordination and control in the management and supply of raw material and supplies for the manufacture of articles, optimizes material and economic resources, generating with the proposed model an improvement of 11% corresponding to economic savings. of $102,124.18 in relation to production costs.
