Maintenance Windows in Small Production Chains
The ongoing project compares maintenance rules on an abstract three-station line and asks how they affect throughput and waiting times.
Problem
Local maintenance decisions can enlarge queues elsewhere. The benefit of a rule at one station therefore cannot be judged in isolation.
Research question
How do different maintenance rules change the throughput of an abstract three-station line? The whole line is considered, not only the station being maintained.
Method
The project uses discrete-event simulation with documented failure assumptions and several random seeds. The runs take place in the modelling workshop.
Evaluation criteria
Throughput, waiting times, downtime and variability are assessed, not merely a single favourable run. Results are not yet available.
Expected outcome
A comparison scenario with a reproducible experimental set-up is expected. The project is ongoing; results are outstanding. Methodologically it connects to P03 without anticipating that project's start.
Limits
The model is not a real factory twin, and no cost savings are claimed.
