Saturday, September 12, 2009

The meeting was called to order by Tim Wilmering at 9:41 am.

Agenda was reviewed and approved as modified by affirmation.

Chair’s Report

P1636.2 is nearly complete, only requiring the EXPRESS model to be completed and reviewed. P1232 ballot resolution is progressing well. P1445 reaffirmation is about to close (if it hasn't already).

Secretary’s Report

Minutes of 09-C meeting were reviewed and approved.

Action Items and Open issues were reviewed.

Liaison Reports

Les Orlidge reported that the NDIA is looking at other techniques for board-level test and diagnosis. As an outgrowth of that initiative, they may be considering other industry standards to assist, including other commercial standards. It is possible that this initiative could lead to other “unforeseen” standards being developed.

Brief Presentations

Simon J. presented a summary of ISO standards on PHM and how they might related to AI-ESTATE. His presentation is recorded as Log #487.

Joe S. presented a brief overview of the MAI demonstration that will be shown during AUTOTESTCON. His presentation is recorded as Log #488.

P1445 Reaffirmation Status

83% return. 100% approval. Two comments: one on the status of the IEEE dictionary and one on the status of a referenced draft. Neither comment needs to be addressed. The ballot closes at midnight (eastern time) on September 12 (today).

Follow-up: After the ballot closed, the statistics did not change.

P1636 Publication Status

No change since the July meeting. Awaiting an update from Mark K.

P1232 Ballot resolution

The subcommittee moved into working group status to resolve ballot comments. Some recommended changes were made to a “DISNEY” model.

Subcommittee Officers

DMC officers will be determined at steering tomorrow. The secretary position will become open with the appointment of Tim and John to the co-chair positions. Matilde Olea and Michelle Harris are going to check with their management to determine if they would have support for taking on the position.

Attendees

Action Item Summary

Old Action Items

• Action Item 07A-3: Darryl B. to obtain a description of the operational/environmental information from recording devices for a commercial platform relevant to diagnostics.

  Status: OPEN This action item is in support of possible new 1636.x Operational Context standard. Tim W. will take an action to attempt to acquire a publicly available DFDAU and FOQA data frame specification.

• Action Item 08D-17: John S. to examine the OASIS DEX on Aviation Maintenance as it relates to SIMICA (including operational context?).

  Status: OPEN

• Action Item 09B-01: Joe S. to arrange for NAVAIR Craig M. (or other stakeholder) to attend DMC meeting to discuss obsolescence model for SIMICA.

  Status: OPEN

• Action Item 09B-02: John S. to create an information model for SIMICA Common, create references to SIMICA Common from the MAI information model, and provide the two resulting information models to Tony Alwardt for inclusion in the MAI revision.

  Status: OPEN The Common model has been completed and is in the process of being integrated with the main MAI model.

• Action Item 09C-01: Mike Seavey to draft the operating procedures for the DMC, to be reviewed, edited, and approved at the 90-2 SCC20 meeting.

  Status: CLOSED

New Action Items

• Action Item 09D-01: John S. to post the new DMC Policy and Procedures document to the DMC website and forward a copy to David Droste for posting on the SCC20 website.

  Status: OPEN

Open Issues

• Issue 07B-1: The current order constraint in 1232-2002 is difficult to understand and, therefore, difficult to use. The DMC decided to “minimalize” the order constraint to focus only on preconditions and added actions to the model. It is recognized that this minimalist construct is at best suboptimal and possibly “broken.” Unfortunately, timing prevents a new construct being included in the model, and the DMC felt something needed to be there to address ordering. For the next revision, a more expressive and usable order constraint facility needs to be incorporated into the model, replacing the current minimalist construct. One proposal on hand is Log #451.

  Status: OPEN Medium Priority

• Issue 07C-1: Need to perform a trade study to determine what new services are actually required. This is essential for establishing a usable scope for the service specification. The focus here is for the next revision of the standard. In particular, an examination of higher-order services should be included.

  Status: OPEN Medium Priority

• Issue 08A-1: Craig M of NAVAIR suggested several additions to the SIMICA model at the 08-A meeting. One of those suggestions was to add a subtype of Design Model: Obsolescence Model. The question is whether the Obsolescence Model can be used a basis for triggering a maturation event and thereby affecting the Diagnostics Model.

  Status: OPEN Low Priority (Need to have meeting with Craig or other stakeholder to determine way forward.)

• Issue 08D-02: Carry S., Erol, Alicia, Darryl, Tony A., John S., and Steve B. to document problems, issues, concerns, and/or difficulties in using the AI-ESTATE standard. Information will be used in the development of the User’s Guide document.

  Status: OPEN High Priority (John S. and Steve B. part done. Erol E. and Pat K. have become Simon J. who has become Myra T.)

• Issue 09B-01: Post-2009 revision of AI-ESTATE to include constructs, facilities, and services to support PHM (especially prognostics). Specific examples that must be covered include gray-scale health and time-to-fail.

  Status: OPEN Medium Priority

• Issue 09C-01: It is unclear that the subcommittee has the resources, knowledge, background, etc., necessary to standardize on “operational context” for either diagnostics or prognostics. For that matter, given that context is domain specific, we are not sure that it is even possible.

  Status: OPEN Low Priority
