Unplanned downtime losses covered with the time
spent for setup time, jig change or unloading and the
waiting time for the material, we are look into the big
picture of the loading process as shown in Figure 4.2 as to
identify the wastages of time spent on the sub-processes
respectively due to the time spending in the process show
bottleneck in the VSM which contribute 129.67 minutes of
non-value added time to the overall lead time of 152.92
minutes. During the loading section, the total set up time is
extremely high which contribute with a value of 123.47
minutes to the loading process. While the changeover time,
inspection time and travel time are lesser compared to the
total set up time
