ISO 10303-239 Activity Model

ISO 10303-239 Activity Model Coverage

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).

IDEFØ Box and Arrow Graphics

This DEX supports a subset of these business activities and information flows. These are highlighted in yellow in the figure Figure 2.

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.

ISO 10303-239 Activity Model Definitions

ISO 10303-239 Activity Definitions

The activity labels in the AAM views above have the following definitions:

Collect data & provide feedback

action to collect and capture into the information technology infrastructure the data generated by support activities or by use of the product

NOTE

Feedback includes:

support task records, including product data collected by the task;
product state and usage records;
resource element state and usage records;
product configuration information;
any issues arising from work.

ISO 10303-239 ICOM Definitions

The ICOM arrow labels in the AAM views above have the following definitions:

APSI and related information

set of assured and related information used to develop and deliver support for a product in focus, including feedback from using and supporting the product over its life cycle

NOTE Related information includes records of the history of the usage or support of realized products, design and support analysis results and reasons why decisions were taken. Such information includes design and failure analysis records, logistic support analyses, running hours, environment descriptions, operating profiles; test results, records of maintenance activities, resources used, and faults found plus any other content deemed relevant to life cycle support.

Error: no icom_inc (information_to_system_operator) found in the AP

product status

notification of the current state of a product receiving support, as confirmed by the authority controlling the work

support feedback

observation on the condition or usage of a product receiving support and on the execution of support activities

NOTE

Support feedback is generated when tasks are performed on a product needing support. It includes information on:

the operation, usage and location of the product or support element receiving support;
the current configuration of the product or support element;
the condition of the product or support element receiving support, before, during or after the support activity, recorded as properties, states or observations;
the progress and status of work;
the resources used to perform work;
issues arising from work done, including proposals for change to the product or support solution.

Error: no icom_inc (task_feedback) found in the AP

work status

information on the progress of activities in relation to a support schedule

NOTE This information on status is transient and will change as the work progresses.
