In summary this model provides to….
1. Define production cycle organization;
2. Formulate Common Performance Conditions;
3. Determine reliability range of MTO and identification of
control modes (strategic, tactical, opportunistic, scrambled);
4. Identify actions to be implemented to improve reliability,
with numerical evaluation in terms of error probability.
