Improvement study of the Overall Equipment Efficiency in a resin plant

Abstract

The resin plant from AkzoNobel Coatings S.L. detected several delays between the production process and the production planning. For this reason, the Production Manager has started a project to reduce the Overall Equipment Efficiency or O.E.E., which is a percentage that correlates total production hours in a year with all the stops, programmed or not. In order to analyse the causes of the delays, the different production times have been studied in different level detail: The general production times for all the resins in a defined period. The reason of the delays for the resins that have reach more rotation in the production planning. Application of the last two points in the implementation of the transferred resin from England. The first part of the thesis studies the reactors responsible for the polyester resins, this study is stopped when the results of the different operations in the process are obtained. The reason for this change is the priority of an important resin from another reactor, the study of the polyester resins serves still as a guide in the new project. In the implementation of the transferred resin the times are studied and the corrective measures are applied to obtain a considerable time reduction in their process. A process with an average occupation time of 36 hours is reduced to 30 hours and thus, affecting the O.E.E:
