Aplicación del control estadístico de procesos y diseño de experimentos para identificar condiciones óptimas de operación del proceso productivo de tableros contrachapados en la empresa Arboriente S.A. de la ciudad de Puyo.

Abstract

This final graduation work aimed to identify the optimal conditions of plywood production line in Arboriente S.A. company through the application of statistical control by processes and experiments design in compliance with the standards of continuous improvement by optimizing the process. The project began with an initial diagnosis to determine the current status of the production line of the board. Using the statistical control, the process variation and its capacity were determined, and, with the study of design experiments the special causes to solve were identified so the conditions for efficient operation of the process were established. As posible causes of variabilty, operators and the depth of cut used were identified. With the implementation of the statistical process control methodology and experiment design, the section of work that negatively affected in the optimization of the production line of plywood of the Company was optimized since a guide for the lathe section was applied. Operators were trained for the correct guide usage and to work in a better way considering quality criteria. In conclusión, the conditions for efficient operation in the development process of the blades were established; the development process was improved by getting intermediate sheets within specifications. Complying with the production requirements, the quality of board was improved, and the industrial dashboard was reduced to 9.58 %. Profits during the months of study increased by 2.37 per cent. It is recommended to study the feasibility for the implementation of a new log unrolling winch. It is also recommended a performance assessment for operators; and finally, it is recommended to train employees in order to work fulfilling the objective and quality principles.
