Abstract Combination of geometric programming (GP) via integer variables is one of the interesting and significant subjects in many optimization areas that has been attracted the attention of many researchers in last few decades. Since practically and in the real problems we can not consider only real variables, therefore integer variables play a very important role in such problems.Our goal in this paper is to consider a multi-objective geometric programming problem (MOGPP) with integer variables. We convert the problem in to a mixed integer non-linear programming problem on using the piecewise linear technique. In this approach each of the objective function in MOGPP is approximated on using the piecewise linear approximation. Then we solve the problem by using the weighted method and find the integer solution to the problem by applying the non-linear branch- and – bound method. Keywords: geometric programming, multi-objective programming, mixed integer non- linear programming, branch-and-bound algorithm | ||
