    Abstract
    Mixed integer nonlinear programming (MINLP) refers to mathematical programming with continuous and discrete variables and nonlinearities in the objective function and constraints. This dissertation has presented active constraints trategy for achieving integer feasible solution from a class of non-convex mixedinteger nonlinear programming problems has a structure characterized by a subset of variables restricted to assume discrete values, which are linear and separable from the continuous variables. Solving the problem used a strategy of releasing nonbasic variables from their bounds, combined with the active constraint and the notion of superbasic variable. This strategy is used to force the appropriate noninteger basic variables to move to their neighbourhood integer points. Successful implementation of these algorithms was achieved on a process system synthesis problem test
     
    Program tak linier integer campuran (Mixed integer nonlinear programming (MINLP)) mengacu kepada program matematika dengan variabel kontinu dan diskrit, dan ketidaklineran dalam fungsi objektif dan kendala. Dalam disertasi ini dipaparkan strategi kendala aktif untuk memperoleh solusi integer layak dari suatu kelas pada masalah MINLP tak konveks dengan struktur dan subset variabel terbatas dan diasumsikan variabel diskrit terpisah dari variabel-variabel kontinu. Pemecahan masalah digunakan suatu strategi untuk menge- luarkan variabel nonbasic dari batas-batasnya dengan kombinasi kendala aktif dan konsep variabel superbasic. Strategi ini digunakan untuk mendorong variabel basis non-integer yang tepat bergerak ke sekitar titik-titik integer. Implementasi dari algoritma yang dibuat berhasil untuk tes masalah proses sistem sintesis.
