Multi flex RNC Philippines Inc. was established in 1975 under RGC Group of Companies Philippines' largest manufacturer and marketer of full-range automotive and commercial polyurethane foam products. The company's main business involves manufacturing automotive seat parts which include Polyurethane (PU) Molded Foams, Integral Seat Foams, and Seat Assembly. The study focuses on the production department particularly in the production of molded foams for automotive seats. The production of this product involves two main production lines namely the Robotech Line and Finishing Line. The pertinent data used in this study is the period from June 2017 to June 2018. Using SWOT analysis, it was determined that there was an output efficiency of 92.998% obtained from the system which deviates a 2.002% from the standard output efficiency of 95%, gaining an opportunity cost of Php3,778,595. To address the problem, the researchers used a why why diagram as their tool to identify all the possible causes of the problem. These causes were then individually validated through pertinent data, relevant computations, thorough observations. Afterwards, a pareto chart was generated in order to identify which of the validated causes had the highest contribution to the problem. The root causes identified were an unbalanced output rate between the robotech and finishing line, there is no standard in execution of mold conditioning and demolding foams, and the incorrect computation of the capacity matrix which they use in computing for their production schedule. Solution generated for these were, in respective order, reduce sub-processes in the Finishing line in order to balance its cycle time with the Robotech line; create standard procedures on mold conditioning and demolding of foams; and correct their computation for capacity matrix cost-benefit analysis was conducted for each proposed solution. In reducing the sub-processes in the Finishing Line, a net benefit of Php1,195,520.50 is obtained. For the solution of creating standard procedures on mold conditioning and demolding, a net benefit of Php 898,076.03 is obtained. And lastly, for the solution of creating a new capacity matrix, a net benefit of Php1,200,08 I. 77 is obtained.
