The 9 principles of the Optimized Production Technology (OPT)

Optimized Production Technology is a method of production flow management. The OPT is mainly based on the identification, management and the resolution of bottle necks, root of useless stocks (mudas) in the production system. Like OPT, the Lean Manufacturing philosophy has a close relationship with the search for optimization by reducing waste. The aim of OPT is to obtain a maximum just-in-time flow through the whole chain, without producing any additional stocks.

The 9 principles of the OPT

1. Balance the flow and not the capacity

2. The use of a non-necking resource is not determined by its availability

3. Use and activation of a resource are not synonymous

4. An hour wins on a bottleneck resource, it's an hour won for the global system

5. An hour earned on a non-neck appeal is nothing, it's just a mirage.

6. The transfer batch may not be and often should not be equal to the processing batch

7. The processing batch must be variable and not fixed

8. The bottlenecks not only determine the flow of the entire system but also define their stocks

9. The programming of activities and productive capacity should be considered simultaneously and not sequentially. Lead-times are a result of programming and cannot be assumed
