E-MAIL: C. Lynn Jenkins, C.L.JENKINS@larc.nasa.gov. NASA/LaRC plans to issue a Request for Offer (RFO) for a safety assessment tool, Aeronautical Analytical Safety Tool (ASSAP), that will address the increased complexity of aircraft systems expected in the 21st century and provide a large system level analysis capability (i.e., the entire aircraft) where subsystem failure independence is eliminated. This will be accomplished through a common analysis framework where large system models will be handled in an automatic divide and conquer approach, utilizing analytical and simulation capabilities. The ASSAP software tool should contain the following integrated minimal capabilities: (a) an automatic (done via software) modular approach to identify independent subtrees (static and dynamic) to be solved analytically or via simulation (b) solution of static subtrees using the Binary Decision Diagram (BDD) or equivalent technique (c) solution of dynamic subtrees using a Markov solution technique (d) solution of constant probabilities, Weibull, exponential, andappropriate other time to failure distributions (e) static and dynamic coverage modeling (f) simulation using the Monte-Carlo approach with importance sampling (g) phased-mission analysis The above capabilities shall be integrated by the Contractor with a Commercial Off-The-Shelf (COTS) based graphical user interface. The ASSAP software tool shall operate and function in a Windows NT server environment. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. The SIC Code and Size Standard are 7373 and $18M respectively The DPAS Rating for this procurement is DO-C9. The provisions and clauses in the RFOand model contract are those in effect through FAC 97-06. All qualified responsible sources may submit an offer which shall be considered by the agency. The anticipated release date of the RFO is on or about November 25, 1998 with an anticipated offer due date of on or about January 4, 1999. An ombudsman has been appointed -- See Internet Note "B". The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in Microsoft Office Suite (Word 6.0, Excel 5.0, PowerPoint 4.0) format and will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application. The WWW address, or URL of the NASA/LaRC Business Opportunities home page is http://procurement.nasa.gov/EPS/LaRC/class.html. Prospective offerors shall notify this office of their intent to submit an offer. It is the offeror's responsibility to monitor this site and/or the CBD for the release of the solicitation and amendments (if any). Potential offerors will be responsible for downloading their own copy of the solicitation and amendments (if any).
