Here is my take on that:
Factors to be considered:
• Span of model
- Factory level planning and control operations.
- Individual manufacturing cell model.
• Accuracy requirements
- Accurate throughput estimate is required.
- Compare two systems - which one gives more
output.
• Variables and policies of interest in the study
Macromodel
-- Inventory control policies
-- Scheduling policies
-- Buffer inventories
-- Part batch sizes
-- Model changeover strategies
Micromodel
-- Number of machines
-- Labor requirements
-- Layout of manufacturing cells
-- Material handling equipment requirements
Hope this helps.
