The main key technique for resolving the Fuzzy Linear Complementarity Problems is presented in this chapter (FLCP). Also, the issue of linear complementarity with neutrophil triangular fuzzy numbers is resolved. It is an essential tool for NP hardstructured and non-convex optimization problems. It finds applications in many fields in scientific, technical and economics. This section also presents a novel method to addressing the problem of Fuzzy Quadratic Programming (FQPP). Intuitionist triangular triangle numbers indicate the cost coefficients, restricted coefficients and the right-hand coefficients. We are solving the FLCP issue of quadratic scheduling using intuitionistic three-way fluid numbers and the implementation of the complementary pivot technique, which reduces it to an intuitionist, linear complementarity problem (IFLCP) .
