Estudio de tiempos y movimientos para la optimización de los procesos productivos en la empresa Arboriente S.A.

Abstract

The purpose of this research is to conduct a time and motion study and subsequently propose improvements for the productive processes in the unwinding area of Arboriente S.A., a company located in the Pastaza province dedicated to the manufacturing and commercialization of plywood panels. The research begins with the collection of information about the company, a detailed description of the productive processes, and an initial diagnosis conducted in the unwinding area through non-structured interviews with area supervisors. To achieve this, process recording sheets, analytical flowcharts, and route diagrams were employed, facilitating the identification of the work method used in each activity. Subsequently, a time and motion study with corresponding analyses was conducted for each subprocess, determining the cycle time and production capacity. It was identified that there are excessive distances between work zones for material supply or waste collection, and it was observed that the debarking of logs in the Peeler and the unwinding process of logs in the Cremona Lathe have longer cycle times. As an improvement proposal, a redesign of the work zones for the storage and selection of logs is suggested, resulting in substantial improvements in efficiency, achieving a 25.87% saving in unproductive distances. Additionally, a new work methodology is proposed to eliminate unproductive activities and reduce idle times, leading to a percentage increase in the production capacity of the peeling machine and the Cremona lathe by 19.74% and 17.84%, respectively. Finally, a procedures manual was developed to instruct operators on the appropriate work method for standardizing their activities.
