A -- INTEGRATED FEM, FUZZY LOGIC AND NEURAL NET CAPABILITY FOR STRUCTURAL OPTIMIZATION. FOLLOW-ON EFFORT. POC Laszlo Berke, Program Manager, M.S. 6-1, (216) 433-5648, Christopher Signorino, Contracting Officer, M.S. 500-319, (216) 433-2767. NASA Lewis Research Center anticipates increasing the value of Contract NAS3-27257 with Expert System Applications, Inc., of Solon, OH, to accomodate Phase II of Probabalistic Learning Automation Networks (PLANS) as described by the following: ''Integrated FEM, Fuzzy Logic and Neural Net Capability for Structural Optimization''. Integrate finite element structural analysis that is capable of probabilistic and fuzzy representation of data uncertainty, with a neural net simulation and an optimization capability. The resulting analysis and optimization capability should utilize the fast executing trained neural net, and its derivative for sensitivities in computationally fast optimization and risk assessment of structures of medium complexity. Interested parties should contact Dr. Berke or Mr. Signorino within 15 calendar days of publication. This effort is set aside for 8(A) companies. (0086)
