Executive Summary. This paper is a systems study on Scorpioline production, one of several products lines manufactured by The Ropemakers Company. The production of this synthetic rope involves three stages, namely extrusion, twisting and laying. The data used in the study were generated from September 1997 to September 1998 involving the man, machine, method and materials of the system. Based on gathered data and its analysis, the proponents determined that the company experiences an extrusion excess wastage of 1.21% on the average of the allowable 2%. This excess extrusion wastage incurred revenue losses for the company amounting to PhP 101,010.47, extrusion excess wastage amounting to PhP 42,385.53 and additional start-up wastage. Based on the identification and validation of possible causes, the proponents found out that the root causes of the problem are machine breakdowns, workers not weighing the proper amount of colorant and resin for desired ratio and no preventive maintenance done on machines. The proposed solutions to resolve the problem are 1) Preventive maintenance on extrusion lines 1 & 6 and 2) Re-orientation of workers regarding Quality and Operational Procedures. Iteration was used to determine the optimal preventive maintenance schedule using Microsoft Excel 97. The optimal preventive maintenance schedule was determined as that giving the highest net benefit from the Present Downtime Cost. Computation results proved that machine breakdown would be eliminated by 100% of implemented and the net present value of the proposed solutions is PhP 1,383,611.15.
