Sistema de planificación de la producción mediante un plan Agregado de producción, para el mejoramiento de la Productividad

Abstract

Through research, a production planning system has been designed through an aggregate production plan to improve productivity. Before the design of the system an analysis of the current situation of production planning is carried out measuring its current productivity which is at 74.39 %, by means of a statistical analysis with the Pareto diagram it is determined that 82.44 % of the sales of greater rotation are the circular saw machines of 600 mm, 450 mm planer and 330 mm edger, of these three types of machines a forecast of future demand is made through a linear regression model from the historical sales of the periods 2017 to 2020, the estimated demand is used as input for the calculation of the three types of aggregate production plans that it is proposed to develop, the three ways with which it is proposed to carry out the production are: Plan 1: variable labor force and exact production, Plan 2: constant labor force and variable inventory and Plan 3: constant labor force and extra time, with the use of Excel software the calculations for these plans are made and it is obtained as a result that Plan 2: constant workforce and variable inventory is the most economical with 170.043.87 dollars with respect to Plan 1 with a cost of 17.0985,34 dollars and Plan 2 with a cost of 176.874.86 dollars, in conclusión Plan 2 is the one that best fits the conditions of the production design and resources of the company, then a production master plan is developed to meet the estimated future demand in this research, and finally productivity is measured after the design of the planning system obtaining an increase in productivity by 12.64%.
