A system study was conducted on CNRGI Inc., a company that provides painting services to automotive manufacturers in the Philippines. The study focuses on CNRGI's line 2 operations, the painting of small automotive plastic parts, for the study period November 2013 to October 2014. Based on the company's specific goals for production quality and employee performance, the line was evaluated to determine its strengths, weaknesses, opportunities, and threats. After the evaluation, a WOT-SURG situation appraisal was conducted on the present system and it was determined that CNRGI's greatest problem is the 85% operational efficiency, or 95 deviation from the target operational efficiency, which results in an annual opportunity loss of Php727,956.94. The problem was further invested, and the identified root cause of the inefficiency is the frequent occurrence of line stop, specifically line stop due to clogged gun, lack of paint, and oven overload. In order to address these issues, multiple solutions were evaluated based on a set of criteria. The proposed system is an integrated resource management and production planning system. The proposed system is a combination of solutions that tackle each of the root causes. The recommended solutions include a semi-automated painting supply monitoring system, a periodic review inventory model, the allocation of a buffer space, a capacity-based production scheduling policy, the purchase of a new spray paint gun, and an instant switch procedure for clogged paint spray guns. A simulation model was designed with ARENA simulation software to better see the impact of the solution. Based on the results of the model, the proposed system will meet the company's target operational efficiency. Additionally, the solution has a net present value of at least Php311,424.40 and expected payback period of under two months.
