The ISO 10303-239 PLCS Application Activity Model (AAM) is an IDEF0 representation of the business activities that set the scope and information requirements for the PLCS standard. The model is composed of a set of figures and a set of definitions of these business activities and their associated information flows.
IDEFØ provides a graphical notation for function modeling of an organization or system. Activities can be described by their inputs, outputs, controls and mechanisms (ICOMs).
This DEX supports a subset of these business activities and information flows. These are highlighted in yellow in the figure Figure 1.
The information flows marked with an asterisk are not explicitly represented within PLCS. This information is instead transferred by other means, e.g., handled by a document.
The activity labels in the AAM views above have the following definitions:
action to define the logical conditions that require a task to be done within a specific support solution definition and deployment environment, including a justification for the selection of the trigger, with appropriate reference to any analysis process that established the trigger condition
action to rationalize the set of necessary tasks and task triggers to develop a viable support plan for each product group, and support concept within a deployment environment
NOTE A further level of rationalization may be required across support plans and resource holdings across many product groups for the PIF as a whole. This activity is not made explicit in this AAM.
The ICOM arrow labels in the AAM views above have the following definitions:
context for which a support solution definition is created
NOTE A deployment environment identifies the set of products and defines the operating and support environment to which a support solution definition applies. A deployment environment may relate to the entire product in focus, or to a subset of it. A product in focus may thus give rise to several support solution definitions, each tailored to a different deployment environment.
possible support plan, corresponding to a specific support policy
set of requirements that shall be addressed during the development of a support solution definition in the context of a deployment environment
NOTE The requirement may include specified performance metrics for the support solution, with threshold or other tolerance values, defined in terms of agreed support characteristics.
relationship between a necessary task and the product element, or elements to which it applies
conditions that require a task to be done, in the context of its assignment to a specific product element within a support solution definition
