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 assist understanding of the scope and information requirements defined in AP239. The model is presented as a set of figures and a set of definitions of the activities and their associated information flows.

This DEX will support a subset of the activities and information flows. These are highlighted in yellow in the figures Figure 1 and Figure 2.

The information flows marked with an asterisk are not explicitly represented within ISO 10303 239 PLCS. The information is handled by a document.

ISO 10303-239 Activity model definitions

ISO 10303-239 Activity definitions

The following terms are used to label activities:

Analyze support feedback

analysis of support feedback from individual tasks to determine exceptions from the support solution, exceptional maintenance needs, the impact on operations, and suggestions for improvement

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:

Extract & collate information

action to extract and collate information from operation and support activities into a form that complies with the information management rules

ISO 10303-239 ICOM definitions

The following terms are used to label ICOM arrows:

APSI

set of information, subject to configuration change management, that is established to develop and deliver support for a product in focus

NOTE   

This term corresponds to the EIA 649 term "product configuration information" which includes:

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.

configuration record

record of the configuration of a realized product

NOTE    Records of configuration status may be required following incorporation of a configuration change, the removal of a serialized item, the replacement of a serialized item or the performance of a configuration audit task.

information to system operator *

information provided to the user or operator of a product needing support regarding the condition of the supported product

NOTE   

Such information can include:

operator feedback *

information provided to support authorities by operators including information on product health and usage, and equipment problems discovered by operators

NOTE    Such feedback can include trouble reports, log books and other data from on-board recording systems, passed to support authorities for analysis. The operator feedback is structured to conform to the information management rules by activity A4.4 and is communicated within this model by the support feedback arrow.

product status

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

product status record

observations, measured characteristics or a record of the state of a product needing support

NOTE    The state of a product can include the existence of fault, an operational state or a status in relation to recognized steps or stages of a support process such as awaiting test or ready for dispatch.

product usage record

information of the past use of an operational product

NOTE    Product use can be quantified against any usage parameter in any pre-defined operational or usage state such as product life, number of landings or hours spent above 50% power. Product use records can be contained in, or extracted from, log books or electronic records, such as tapes or discs, as provided by product operators or other personnel.

resource usage record

information on the past use of a resource in the course of performing one or more support tasks

NOTE    Resource usage includes the consumption of spares or consumables, time spent by human resources in performing support tasks and the usage of support locations or facilities. Usage may also be measured by other parameters such as elapsed time, number of starts or cycles of operation.

support element status record

observations on the condition, measured property or status of a support element that has been, or is being used, as a resource for a task

NOTE   

Possible states of a support element include:

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:

support issue

request for action to resolve, or an expression of concern about, a problem arising from working on a product needing support

NOTE    This may include requests to modify the product or support solution definition.

support task record

information on the state of a current or completed activity, including reports of completion of individual task steps

task feedback *

information, in any form, derived from observation of a realized activity including progress, findings or resource use, prior to the capture of this information in the format required by the information management rules

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.
