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 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.

ISO 10303-239 Activity Model Definitions

ISO 10303-239 Activity Definitions

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

Arrange support element provision

action to arrange provision of required resources, in the required quantity and state, at the specified location, on the specified date as required by a resource schedule

NOTE This activity assumes the availability of a standard transaction set that can be used to achieve provision of the necessary human and material resources required by scheduled tasks. The transaction set is assumed to include sufficient requests and responses to complete the planning (activity A4.1) and execution (activity A4.3) of support activities.

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.

Execute authorized task

action to execute each released task by performing the steps specified by the task procedure, including any associated data reporting

ISO 10303-239 ICOM Definitions

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

Error: no icom_inc (authorised_task) found in the AP

maintenance need

work request identifying additional support tasks that may be needed to restore products to serviceable conditions

request for task procedure

request for the development of a task procedure for an intended task not addressed by the support solution definition

required resources

identification of the resources needed to support scheduled work at one or more support opportunities

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.
