ANALYSIS AND OPTIMAL ALLOCATION OF TRANSPORTATION OPERATORS IN PRODUCTION LINE

Productivity improvement is necessary as a major strategy to remain competitive in a global market. Utilization of transportation operators was studied in a hard disk drive manufacturer. The problem found was an inappropriate number of transportation operators that had affected the idle time of operators. The objective of this study was to determine the optimal number of transportation operators in hard disk drive manufacturing processes. To solve such a problem, work study was conducted. Work elements of transportation operation were identified. Travelling distance was measured using a measuring tape, whereas transportation time was recorded using stopwatches. Then, standard time was determined. Finally, the minimum number of transportation operators was calculated using the standard time. The number of operators could be decreased 3 operators per shift or 6 operators per day. This results in 37.5% productivity improvement. It was concluded that work measurement was an important tool used for increasing productivity of transportation operation.
