Tour and Break Scheduling for Shift Operators in Hard Disk Drive Manufacturer

This research is conducted based on current condition of shift operator's schedule in Hard Disk Drive manufacturer. The schedules considered are break schedule and work pattern. It is revealed that break schedule violates regulation from Thailand's Ministry of Labor, and work pattern violates its customer regulation, and Electronic Industry Citizenship Coalition (EICC). Both break schedule and work pattern are developed by generating algorithm, building VB program on Microsoft Excel, and analyzing the result to fulfill all regulations. The first schedule developed is break schedule because output of break schedule becomes one of input on developing work pattern. Break schedule algorithm is generated based on current schedule and regulation from Thailand's Ministry of Labor. Otherwise, work pattern algorithm is generated based on current pattern, customer regulation, EICC, and Thailand's Ministry of Labor. The result shows that combination of breaks in break schedule needs to be revised into 45 minutes each respectively. Meanwhile, the best work pattern is same as the current regular work pattern but with new perspective on calculating workweek. It can be concluded that both developed schedules fulfil all regulations.
