Study Phases in Engineering Models



The main design activities in a Concurrent Design study are performed by the design team within the frame of an Engineering Model. This section describes the different Study Phases that an engineering model can have and the different allowed actions for these phases.

More information is given in the related topics of developing engineering models, and how combinations of Model Kinds and Study Phases can be typically used in engineering models.

Different Types of Study Phases

Engineering models can be in different Study Phases, according to the design process in a Concurrent Design Activity. Model Kinds can be of the following types1:

Using Study Phases in Engineering Models

A main reason for the Study Phase of engineering models is to provide an indication to the users of its status and by extension also the status of the design information contained in it. The Study Phase loosely linked to the concept of the Model Kind of an engineering model.

The study phases are mainly applicable to an engineering model that is of the Model Kind Study Model. For this, an engineering model would start in the Preparation Phase to perform preliminary engineering tasks with a core team.

Typically, while performing the Concurrent Design Activity on this model, it will go through the consecutive phases, i.e. the Design Sessions Phase and the Reporting Phase. Note that an engineering model has to be in the design sessions phase to be able to create iterations.

After the Concurrent Design Activity has ended, it can be set to Completed Study. This will indicate to all users that have access to this engineering model that it has gone through the full design process cycle. It can therefore be expected to contain a full model with identified options, element definitions and usages, defined states, parameters (and their subscriptions) with the corresponding values for which the publications and iterations provide an audit trail for their evolution.

Such a Completed Study engineering model may well provide a basis for e.g. Template Models, provide new inputs to existing or newly created Catalogue Models, or copied to create a new Scratch or Study Model.

For more details, see the description of their typical use in engineering models.

Edit Study Phase for an Engineering Model Setup

A person with the access right Modify on the class Engineering Model Setup is allowed to edit the Study Phase of an engineering model.

To edit the Study Phase of an engineering model, select the Edit Engineering Model Setup imgicon or in the context menu select Edit. On the Basic tab, edit the Study Phase. After making the required changes, click Ok.

For the impact of changing the Study Phase, see the description of their typical use in engineering models.
