Abstract The demand of automobiles is continuously increasing in the automobile sector of Pakistan. Keeping in view the increasing demand of the automobiles, this research work is done in a well-known automobile assembling plant. Objective: The aim of the research is to improve the productivity of an automobile assembling plant with special focus on quality and quantity. The paint shop of the plant is considered as the major bottleneck in low productivity. Therefore, it is selected as the case to improve productivity and fulfill the market demand. Methodology: Takt time of the identified process is recorded on the standard sheets. The major causes of low productivity are identified by cause and effect analysis. The alternative measures to improve the productivity are identified and compared. The alternates are proposed to the company. Results and Conclusions:
The annual data is collected from Pre-treatment Electrode Deposition Line (PT-ED Line). Takt Time in one of the process of PT-ED Line of paint shop is reduced from 2.04 mins to 1.78 mins. This is done with the help of electrodes replacement and increasing of amperes of the electrodes in the Cathode Electrode Deposition (CED) process. This reduction in takt time increased the daily production of paint shop from 245 units to 280 units. This improvement in production somehow will fulfill the market demand of the selected automobile plant. The calculations are made for each type of shift operations at current, future and ideal conditions.
