The Manila Glass Plant is a subsidiary of the San Miguel Packaging Products division, which is in charge of producing high quality packaging product for the San Miguel Corporation. The Manila Glass Plant also dominates 70% of the total industry sales, which explains why it is considered as the number one manufacturer of glass containers in the Philippines. The group limited it's study to the procedures being done in the Operations Department's Glass Forming Division, because this is where the heart of manufacturing bottles occur. The main problem of the plant is the During the year 1997, there is deviation of 2.21% metric tons loss reducing the production output by 5,662,092 bottles. This problem proved to be initiated by the insufficient number of teams to perform the Job Change procedure, which resulted to waiting time. The group, through the use of an ARENA 3.0 simulation study, modeled the system to ensure that the results will represent the different alternatives enumerated by the group. An evaluation of alternatives was done in order to determine the best alternative, which is to add another shift to perform the Job Change procedure from 3:00 p.m. to 11:00 p.m. to support the only Job Change shift working from 7:00 a.m. to 3:00 p.m. Through results gathered from the simulation study, the production output of bottles increased beyond expectation of approximately 30% when implementing the proposed system. It minimized the metric tons loss resulting to an increase in the production output, such that, the target output of the company should be 114,991,327 bottles, which is 125% of the total output in 1997. An eight-week program schedule was also arranged for the effective implementation of the proposed system.
