Maintenance function must be decentralised apart from the size of the manufacturing organisation for its better functioning
The component produced on completely automatic machines may be subjected to sampling inspection while parts produced on semi automatic and completely manually operated machines require cent percent inspection
In case of backward pass computation, the latest event time of the burst event equals the smallest of the difference between the latest event time of the head event less duration of the activity converging on the head event
The component produced on completely automatic machines may be subjected to sampling inspection while parts produced on semi-automatic and completely manually operated machines require cent percent inspection
Objective of work study is to improve productivity
root causes of many failures in meeting planned production can be attributed to poor medium / long range planning
The problems of congestion, bottlenecks and backtracking can not be visualised by using templates and models
