3. Model Mgmt Objective Problems of Model Mgmt:
Snapping & maintaining a baseline
Managing the decomposition of models—functions, logical, interfaces, etc. How do we treat as part of baseline. Who owns the parent-child relationship (what can the child model do, etc. who controls what). Who owns allocations? (is it functions?) What is the span of control—top-down and horizontal (how does this work in CM; in assembly;). How is CAD model mgmt different than Matlab model mgmt? Who owns it and what do they own? How do you breakup models, etc. (discuss how we are trying to do this today at our next meeting)
Manage shared models…same model across multiple programs (manage interdependencies across models). Changes to models on one program that affect others. How to manage model merging. How are these models different than CAD models? Can we use software CM environments for this? Clearcase vs PLM—logical vs physical
How to manage the variant of the model. How to model a variant? V8 vs V6, high fidelity vs low fidelity, version of a product vs versions of models.
(Related subject) How much modeling is enough? What level of fidelity is sufficient?
Exchange of information among models. Model data dictionary? Model structures (what goes along with the model—model supporting information) . Establishing a framework for exchanging model information…model architecture; how to manage associated data.
Traceability across models across levels of fidelity (what level of traceability).
Matching fidelity of the model to the use. Mix and match models.
Tracing through models…what parameters flow through a series of models. Where did the data come from. External files used with a model
