Modelo de programación de producción basado en simulación en una empresa de papel higiénico

Abstract

EXECUTIVE SUMMARY This study objective is to design a simulation-based programming model in a company that produces toilet paper. Initially, an analysis of the current situation is carried out and the production process of the Grupo Familia S.A of Ecuador specifically Rodumat Line for institutional paper is characterized. Activities with constant machine cycle times and activities with variable cycle times due to labor intervention are identified. In the latter, the adjustment of the probability distributions is obtained and all the parameters that intervene in the simulation model are detailed, such as programming assumptions, production line, measurement units and production capacity. Three output variables of main interest are defined: throughput or production capacity, logs in the accumulator or work in process, and use of workstations. Subsequently, the model is designed in FlexSim 2019 and a dashboard is linked to obtain results, based on quantitative comparison, a final precision error of 0.017 percent and an adequate number of replicates of 12 are calculated. Finally, it is experimented with 7 different programming strategies that are classified in three approaches: staggered start-up, capacity aggregation and dynamic constraint. In each one, the values of the output variables are obtained, descriptive comparison and comparison are made using Bonferroni from which the best programming strategy is chosen by means of 8-hour staggered start-up. The results show an increase in production capacity of 6.34 percent, so the proposal is effective.
