A system study on the production section of Polygon Manufacturing Corporation

Executive Summary. Polygon Manufacturing Corporation is the leading manufacturer of cast acrylic sheets. It is the only manufacturer of acrylic sheets certified by the International Standard of Organizations or ISO 9002 in the Philippines. The main goal of the company is to manufacture products of high quality and satisfy its customers. The group conducted a systems study on the production department of the said company particularly the problem on defect rates. The defect rate during the course of the study is 6.51%. The group was able to identify the top three defects of the acrylic sheets which include wrinkles, glass bites and color stains. After gathering data, conducting interviews and extensive study, the group generated alternatives to solve the problem. The alternatives were evaluated through Kepner-Tregoe Decision Analysis. Through these alternatives, the group was able to solve the problem on defect rates by increasing Class A yield by 7.15%. The proposed solutions recommended by the thesis group to the company are to assign QA personnel for viscosity control measurement and assign more specific pool retention time for each sheet thickness. The group also proposes to buy new sets of glass moulds and to modify the containers. Seminars and quality circles must also be implemented to ensure that the policies are being observed. The Net Present Value for the proposed solution was calculated at P 1,352,394.43 for 5 years. The group recommends the further studies be done by the company to improve its present system
