E-MAIL: Sandra J Tetley, sandra.j.tetley1@jsc.nasa.gov. NASA/JSC plans to issue a Request for Quotation (RFQ) for the development of software tools which use advanced model correlation algorithms for use on Shuttle payload math models including the following: Generalized Error Locator algorithm; implementation of Genetic Algorithms for optimizing model updating using Bayesian objective functions; Non-sensitivity-based model updating based on Structural Dynamics Modification theory. In addition, the selected vendor shall develop pre-test planning software tools implementing Maximum Average Kinetic Energy, Eigenvector Product, and QR Decomposition instrumentation locating algorithms and FRF and Mode Indicator Function Excitation-evaluating algorithms. The vendor shall deliver Matlab-based software programs to conduct pre-test planning and model correlation utilizing outputs from COSMIC NASTRAN and software tools developed under this contract. The software delivered under this contract must be demonstrated on a model of a P6 payload. The vendor shall investigate combining multiple model and static test results into one model correlation process, write and deliver a final report on such. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/JSC intends to obtain this work and resulting software from Ztech Engineering Services in Friendswood, Texas. Ztech key personnel have developed many of the methods called for by this procurement and has been instrumental in previously coding some of these algorithms. Ztech is the only company which has used advanced dynamic model correlation tools to update complex NASA payloads such as the P6. This unique knowledge is required to develop the COSMIC NASTRAN model updating capability. Therefore, it is in the best interest of the Government to obtain this expertise and Ztech Engineering Services is the only known qualified source. In accordance with FAR 6.302-1 and U.S.C. 2304(c)(1), a Justification for Other than Full and Open Competition stating a unique source is being prepared. Technical questions should be directed to the Technical Monitor for this procurement, Michael Grygier at (281) 483-6398. The Government intends to acquire a commercial item using FAR Part 12. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on July 19, 2000. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
