Multistage Manufacturing System (MMS):
LQGP Problem Example
MMS Numerical Example and Results
- Graphs are for MMS with 3 stages with planning horizon of 40 hours
and production goal of 10,000 pieces.
- These graphs are for second stage with 3, 4, and 5 operational machines.
- Surplus aggregate level is assumed zero for entire planning horizon.
- Production level is utilization of all operational machines
for a given stage.
- Virtual static production level is rate of production not
influenced by repairs or failures in the remaining time of planning
horizon.
- Production level adjusted with regular control anticipates
repairs and failures in remaining time of planning horizon.
- Time is measured from beginning of planning horizon.
- State ID describes number of operational machines for all
stages. See "State ID Table".
- If production level is greater than 1, a physically unrealizable
situation, then production level is set to 1 and surplus
aggregate level is adjusted to for shortfall.
