UMLTM for Systems Engineering RFP


RFP:

Refer to Chapter 6 and Appendix A.2 of the RFP for specific information on UML for SE. The other sections of the RFP provide general information for submitters.

UML for Systems Engineering RFP - ad/03-03-41 (28 March, 2003)

Objectives of This Request For Proposal (RFP):

This Request for Proposal solicits submissions that specify a customization of UML™ for Systems Engineering (SE). The customization of UML for systems engineering is intended to support modeling of a broad range of systems, which may include hardware, software, data, personnel, procedures, and facilities.

The customization of UML for SE should support the analysis, specification, design, and verification of complex systems by:

·        capturing the systems information in a precise and efficient manner that enables it to be integrated and reused in a wider context

·        analyzing and evaluating the system being specified, to identify and resolve system requirements and design issues, and to support trade-offs

·        communicating systems information correctly and consistently among various stakeholders and participants

A UML-based language for modeling systems will support the exchange of analysis, specification, design, and verification information using standardized notations and semantics that are understood in precise and consistent ways. This will improve communication among people who participate in the systems development process and promote interoperability among tools that support this process. The language may also establish a common modeling framework that can be further customized to meet specific needs. The use of UML as a base language will extend the user skills, tools, and knowledge that currently exists to additional users.

The customization of UML for systems engineering is being closely coordinated with a related ISO STEP effort known as AP-233, which is defining a data interchange standard for systems engineering. The combination of these two efforts is expected to provide a comprehensive framework for the exchange of systems information using standardized notations and semantics.

To the degree that schedules permit, UML for SE should be based on adoption in progress for a UML 2.0 specification.

The following are the references referred to in Section 6 of the RFP:

6.2        Related Activities, Documents and Standards

OMG Systems Engineering Domain Special Interest Group (SE DSIG),

6.2.1             International Council on Systems Engineering (INCOSE)

INCOSE is an international not-for-profit membership organization that develops and promotes the system engineering approach to multi-disciplinary product development. It worked with OMG to help launch the SE DSIG initiative, which held its kickoff meeting in September, 2001, and is helping to coordinate UML for SE-related activities with ISO and other groups. It also helps to develop, maintain awareness, and provide review for model-driven approaches within the systems engineering community.

 

6.2.2             ISO STEP AP-233 Effort

The SE DSIG effort is closely aligned with the on-going ISO AP-233 standard activity. AP-233 is focused on developing a data interchange standard for systems engineering, which is intended to provide a neutral data format to exchange systems engineering information among tools. The AP-233 project is a working group of ISO TC-184 (Technical Committee on Industrial Automation Systems and Integration), SC4 (Subcommittee on Industrial Data Standards), and is part of the larger STEP effort, which provides standardized models and infrastructure for the exchange of product model data. The result of this effort will be part of the existing ISO 10303 standard that will provide an “Application Protocol” for Systems Engineering. One of the joint SE DSIG and AP-233 tasks is the development of the Systems Engineering Conceptual Model, which is intended to help align the requirements for UML for SE and the AP-233 data interchange standard.

6.2.3             Requirements Analysis for UML for SE

This document (Version 0.4 dated November 12, 2002) was used as a basis for analyzing the various sources of requirements for UML for SE, for identifying perceived issues regarding gaps in UML 1.x related to systems engineering, and for exploring potential solutions for UML for SE.

6.2.4             SE Terms and Definitions

The UML for SE Definitions List provides a self-consistent set of systems engineering terms and definitions that are referenced in the requirements section of this RFP. This list defines many of the specialized systems engineering terms used in this RFP and appears under the SE Terms and Definitions heading on the UML for SE RFP page. A core subset of these definitions is included in the glossary in Appendix A.2. In addition, the UML for SE RFP page identifies other sources of definitions, including industry standard definitions, the definitions in the semantic dictionary that accompanies the SE Conceptual Model, and definitions from the UML specification. It is recognized that continued effort is required to fully harmonize all of these terms and definitions with each of their sources, including definitions used by the systems engineering user community and definitions used in the UML specification.

6.2.5             SE Conceptual Model and Semantic Dictionary

The SE Conceptual Model and Semantic Dictionary is a joint effort between INCOSE, AP-233, and the OMG SE DSIG to develop a top-level information model to characterize basic systems engineering concepts. Early versions were developed as part of the Systems Engineering Data Representation and Exchange Standardisation (SEDRES) project, a European consortium project that led to the formation of ISO AP-233.

6.2.6             Responses to UML for SE Request for Information (RFI)

The SE DSIG issued an OMG Request for Information (RFI) in February 2002 to collect input on existing experience and to gather requirements on the use of UML for SE. There were thirteen responses to this RFI, which were reviewed at the June and September 2002 meetings of the SE DSIG.  The complete set of RFI responses and presentations regarding these responses are available on the UML for SE RFP page. In addition, there were two RFI responses to the UML 2.0 RFI in 1999 that addressed the application of UML for SE, and which are also identified on below.

  • MDSD UML 2.0 RFI Response (ad/99-12-24)

  • OOSEM UML 2.0 RFI Response (ad/99-12-23)

6.2.7           Reference Papers

Several papers have been written on the use of UML for systems engineering, some of which provided some excellent insights to validate the requirements, and which also offer potential solutions.  In addition, there are some reference papers for non-UML based systems engineering approaches that may assist in assessing how UML for SE might support or contrast with these approaches. Some of these papers are available from the “Reference Papers” link of the UML for SE RFP page.

6.2.8             Systems Engineering Process Standards

The SE DSIG effort is focused on establishing standards for system modeling. System modeling should be an integral part of the activities and techniques defined by a systems engineering process and methodology. There are several standards for systems engineering processes, including ANSI/EIA 632, IEEE 1220-1998, and ISO/IEC 15288. Each of these process standards defines a set of primary activities that must be performed to implement systems engineering. There are also a variety of methodologies for implementing the systems engineering process, which include both structured and object-oriented methodologies. Some examples of systems engineering methodologies are referenced in the UML for SE RFI Responses, and many others can be found in the INCOSE systems engineering papers, journals, and handbook, as well as a broad array of systems engineering texts. These process standards and methodologies help to provide additional context on the variety of roles that a systems modeling language might fill.
