Ron Wood kicked off the meeting since Jim Mays had travel problems. Tony Fry attended the WG 3 Opening Plenary, Annex C contains that report. Annex A contains acronyms used in the T 23 minutes and annexes.
The first item was to review and update the agenda presented in Annex B.
Project status reports were provided.
Will conclude May 2003, goals final approval of AP215, 6 and 8. AP216 the first Ship AP to reach IS and is in Geneva. We are waiting for approval by ISO for national standards bodies to distribute it. AP218 unanimously passed its IS ballot. Should be ready for convener review by April 2003. AP215 unanimously passed its IS ballot. Document should be ready for convener by April 2003. See Annex M.
See presentation Annex F. Doing translators for APO 218 structures and AP 227 piping. Also doing coordination with the ISO TC184/SC4/WG3/T23 group. Doing 215/216/218 AIM translations for:
AP 227 piping data exchange is being supported by
E-STEP has produced a set of test data for the Torpedo Weapons Retriever (TWR).
A significant demonstration will be performed next month involving all systems and translators. The demonstration will be presented at:
World Ship Maritime Conference in
Working on a proposal to do AP 227 HVAC, Electrical, AP 215 Arrangements, and AP209 Composite and metallic structural analysis and related design.
See Presentation Annex D. The project will develop a pilot to enable exchange of steel fabrication work. It Builds on Integrated Shipbuilding Environment (ISE) and adds Mfg Rule base, CAM Interfaces. Technical lead of the project is NGIT, although Northrop Grumman Ship Systems is the project manager. Atlantec and STEP Tools will do STEP related work. Phase 0 is requirements development.
See presentation in Annex L. AP227, plant special configuration. AP updated to provide functionality of piping, HVAC, cable trays, and now mechanical systems.
See Thursday minutes for presentation.
Concentrating on AP227. There has been some discussion about
updating the EMSA ARM based translators (EMSA Protocols), but this needs to be
done against the latest version of the ARM models. The current BBs logged into the server are only the DIS versions. Currently there is no funding to update the
BBs to IS. Pete Lazo estimates that it
would take 2 weeks to do so, however most of the change are editorial and not
to the model. EMSA has 4 new academic
members from the former
No report at this meeting.
Action items were reviewed and updated. See Annex E for the updated action list and new actions from the San Diego meeting.
Project
Briefings -
Module/Modular
AP Status - Meeting on process and guidelines held Sat 08/03/2003 the results
of which were presented at the Opening Plenary. Test case and examples aspects need to be raised with
Advance SC4
Resolutions - Non of special interest to WG3
Items for
PPC + Conveners meeting - As reported at the Opening Plenary effective Sept
this year deadlines for production of AP changes to 5 years (was 7) and Stage
to Stage reduced to 2 years (was 3).
Reference Dictionaries
- Problem: any engineering properties measured by any engineering device is
vast and needs to be controlled within a standard. Suggest this is achieved by reference dictionaries and based on
Mil handbook 5. Concern that these
dictionaries are not held in a structure and produced on a ad hoc basis with no
relationship to one another. Needs a
full meeting (joint WG2/WG3) on this in Stuttgart.
A problem
of maintaining these dictionaries has be identified, hence sustainability and
funding need to be considered.
Rule
Writing - Recommendations for writing EXPRESS rules were presentated by Jochen
Haenisch. Style produce based on QUERY
statement to reduce the amount of memory.
Proposed a better rule writing style using a ”function”. Recommendations:
Jochen
Haenisch to write up a White Paper on this and issue within one month to be
discussed further in Stuttgart.
Procedures - All teams to
write minutes within sated timescales.
Requirements for off site meetings are to be brought to closing
plenary. Abstracts needed for TS, FDIS and IS. Communications should use the exploders.
Other Issues - Raised issue re liaison with SC10 on CAD definition.
Team Leaders - EXPRESS Server needs copy of EXPRESS for each of the WG3
APs:
The spreadsheet containing the list of Ship STEP products was reviewed. See Annex J for the current list posted on the T23 web page. Participants should review this and send any updates to Jim Mays.
Liaison WG2: Rob Schuler; PPC Burt; See annex H.
Rob Schuler discussed the TWR database. NSWC is collecting any examples of product model data for this ship for use in demonstrations. Technical manual is available. Tony Fry will investigate digitizing the documentation to also make it available on line. See annex I.
Burt Gischner provided summary of the advanced ballot comment workshop, the final ballot comment workshop planning.
Tim Turner discussed the mechanical systems comments against AP 227. 29 new entities, 3 new types and 5 modifications to existing entities. Of the 29 new entities 5 are key, 2 are utility, and 22 are mirrored logical entities similar to piping.
Burt Gischner gave a summary of the meeting. He described guidelines for the editorial changes and AP 216 conformity. No ‘no’ votes were recorded so an FDIS is not required for AP 218 or AP 215. See Annex P.
Jim Mays discussed the SEDS form in Annex K. The led to a discussion on a PDES, Inc. project for ships focused on a Plugfest. Jim Mays will get information from PDES, Inc on guidelines, lessons learned, costs, etc so we can discuss planning a T 23 Plugfest in collaboration with PDES, Inc and/or NSRP. Jim Mays presented the form for submitting SEDS on AP 216 and the other T 23 APs as the are tested and used. See Annex K.
Much of the discussion was on harmonization with ISO 14649. The representatives from the ISO 14649 were in favor of implementable ARM. The 10303 community argued the benefits of using an AIM implementation. The most STEP NC AP 240 effort has been made in milling (and this seemed to be the example used in the harmonization discussions). Turning will be addressed later. The Integrated Steel Production Environment (ISPE) was briefed. The thrust is to develop commercial tools that will take AP 218 data and manufacture steel structural parts. This means NC plate cutting information will also be available for consideration in AP 240. Electro-Discharge Machining (EDM) was also mentioned. NC pipe bending is important for the shipyards. It has unique characteristics like wall thinning, spring back (function of material type, thickness, induced stress that would be accounted for in the NC model) and a defined working envelope to avoid collision with other equipment. CSG may be required in AP 240. We will propose a pipe bending briefing with manufacturing in Stuttgart. There are strong similarities between pipe bending and sheet metal bending.
The following are within the scope of the system engineering application protocol:
a) products with conformity to the concept of a system;
b) system definition data and configuration control data pertaining to the design and the validation phases a system’s development;
c) requirements and requirement analysis data;
d) functional and functional analysis data including functional behaviour specifications.
e) physical architecture and synthesis data priving a high level view on the system under specification;
f) elements for representing the tracing of requirements and allocation of functions.
AP 233 is in the process of dividing the AP requirements into modules. Modules under discussion are:
Other non-AP233 modules that can be used for Systems Engineering are:
The AP 233 team is still discussing definitions, clause 3 information.
T23 will start in updated project plan identifying Systems Engineering AP 233 and Product Lifecycle Support AP 239 as APs that will support important ship industry data exchange needs.
John Kendall attended. ???????????????
Gerry Radack attended the PLIB meeting. They are working on setting up libraries now that their standards are finished. Chinese are working on a dictionary for fasteners part 511 and Japanese are working on measuring instruments part 501. T 4 is working on a cutting tools library and liaison with TC 93.
See Annex N. Yong-Dae Kim provided the STEP Center report for Korea.
Joint Manufacturing liaison should include a T23 presentation on pipe bending. Tony Fry will take the lead. See Annex O for Stuttgart agenda. Annex Q contains the closing plenary report.
