scope:

This NASA Technical Standard establishes uniform practices in modeling and simulation to ensure essential requirements are applied to their design, development, and use, while ensuring acceptance criteria are defined by the program/project and approved by the responsible Technical Authority.

This NASA Technical Standard provides an approved set of requirements, recommendations, and criteria with which models and simulations (M&S) may be developed, accepted, and used in support of NASA activities. As the M&S disciplines employed and application areas involved are broad, the common aspects of M&S across all NASA activities are addressed. The discipline-specific details of a given M&S should be obtained from relevant recommended practices.

Purpose

The primary purpose of this NASA Technical Standard is to reduce the risks associated with M&S-influenced decisions by ensuring the complete communication of the credibility of M&S results. The requirements and recommendations contained herein provide a basic set of best practices applicable to any M&S. This NASA Technical Standard achieves this by establishing a minimum set of requirements for the key elements related to M&S, including development, maintenance, operation, results analysis, training, credibility assessment, and reporting. This NASA Technical Standard covers what needs to be accomplished and communicated, not how it is to be done. Discipline-specific recommended practice guides should be consulted for specific applications or methodologies.

Applicability

This NASA Technical Standard:

Is applicable (relevant and appropriate) to all M&S used by NASA, its contractors, and its partners.

  • Covers M&S used in design, development, manufacturing, ground operations, and flight operations.
  • Is highly recommended for M&S used in critical decisions or functions.
  • Any required application of this NASA Technical Standard is to be specified in program/project/organization/office directives and may be tailored (refer to section 1.3 for tailoring requirements).

[M&S 1] When conflicts exist between this NASA Technical Standard and voluntary consensus standards (VCS), this document shall take precedence, except in those cases where the VCS is invoked by applicable Government regulation.

This NASA Technical Standard is approved for use by NASA Headquarters and NASA Centers and Facilities and may be cited in contract, program, and other Agency documents as a technical requirement. It may also apply to the Jet Propulsion Laboratory and other contractors only to the extent specified or referenced in applicable contracts.

Verifiable requirement statements are numbered and indicated by the word "shall"; this NASA Technical Standard contains 39 requirements. Explanatory or guidance text is indicated in italics beginning in section 4. To facilitate requirements selection and verification by NASA programs and projects, a Requirements Compliance Matrix is provided in Appendix A.

intended Use:

The expected purpose and application of an M&S.
