APPGE08a1 1
Utilization Rate APP Functionality
= Scheduled operations = Operation to be scheduled
Example A - resource 1, utilization rate: 100% or no. of resources: 1
Time
Example B - resource 1, utilization rate: 50% or no. of resources: 0.5
Time
Adjusting norm times via work centers and/or resources Models the effects of, for example:
- New or old machines- Different operator experience

Maximize and Protect Flow APP Functionality
Link order release to finite capacity Schedule based on the bottleneck’s
capacity Use a time buffer before a
bottleneck to ensure it is kept busy Use inventory buffers only in
strategic places to protect throughput, e.g., before bottleneck and assembly W/C resources
