4 Information requirements

This clause specifies the information requirements for the Activity or state space application module.

The information requirements are specified as a set of units of functionality, application elements, and application assertions. These assertions pertain to individual application entities and to relationships between application entities. The information requirements are defined using the terminology of the subject area of this application module.

1. - A graphical representation of the information requirements is given in annex C.
2. - The mapping specification is specified in 5.1 which shows how the information requirements are met using the integrated resources of this International Standard. The use of the integrated resources introduces additional requirements which are common to application modules and application protocols.

4.1 Units of functionality

This subclause specifies the units of functionality (UoF) for the Activity or state space application module as well as any support elements needed for the module definition. This part of ISO 10303 specifies the following units of functionality:

• Activity_or_state_space_dimensionality;
• Fusion_of_activity_or_state_space;
• Product_for_activity_or_state_space.

This part of ISO 10303 uses the following units of functionality:

• Engineering_analysis_basics;

  NOTE - The Engineering analysis basics AM contains supertypes of the application objects in this AM. These supertypes have no attributes and merely clarify the meaning of the application objects. These supertypes have no impact on the MIM.

• Activity;
• Product_feature_space_dimensionality;
• State.

The units of functionality and a description of the functions that each UoF supports are given below.

4.1.1 Activity_or_state_space_dimensionality

The Activity_or_state_space_dimensionality UoF specified the nature of an activity or state space.

NOTE - An Activity within an Activity_or_state_space can be a finite component within a discrete event view of a larger Activity, in the same way that a Product_specification_or_set within a Product_volume_space can be a finite component within a lumped parameter view.

NOTE - A State within an Activity_or_state_space can be a finite component within a continuous view of an Activity, in the same way that a Product_specification_or_set within a Product_point_space can be an infinitesimal component within a continuous 3D volume view.

The following application objects are used by the Activity_or_state_space_dimensionality UoF:

• Activity_or_state_space;
• Activity_space;
• State_feature_space;
• State_space.

4.1.2 Fusion of activity or state space

The Fusion_of_activity_or_state_space UoF specifies:

• the relationship between an activity and the space of component activities or states within it;
• the relationship between a state and the space of component states within it;
• the relationship between a component activity or state and a space of which it is a member.

The following application objects are used by the Fusion_of_activity_or_state_space UoF:

• Activity_or_state_space_for_activity;
• Membership_of_activity_or state_space;
• State_feature_space_for_state.

4.1.3 Product for activity or state space

The Product_for_activity_or_state_space UoF specifies the space of features that:

• forms a 'product' (i.e. ´) space with an activity or state space; or
• defines a State_feature_space.

The following application objects are used by the Product_for_activity_or_state_space UoF:

• Components_of_product_feature_and_activity_or_state_space;
• Components_of_state_feature_space.

4.1.4 Engineering_analysis_basics

This UoF is defined in the Engineering_analysis_basics module. The following application entities from this UoF are referenced in the Activity or state space module:

• Classification;
• Components_of_physical_space;
• Fusion;
• Physical_space.

4.1.5 Activity

This UoF is defined in the Activity module. The following application entities from this UoF are referenced in the Activity or state space module:

• Activity.

4.1.6 Product feature space dimensionality

This UoF is defined in the Product_feature_space module. The following application entities from this UoF are referenced in the Activity or state space module:

• Product_feature_space.

4.1.7 State

This UoF is defined in the State module. The following application entities from this UoF are referenced in the Activity or state space module:

• State.
