【Abstract】 In this paper a piecewise linearization global Optimization Algorithm is proposed for the linear multiplicative programming,which has a lot of important applications in various areas such as financial optimization and economy plan.Firstly,the original program is transformed into the equivalent problems.Second,utilizing piecewise linearization technique,linear underestimates of the objective and constraint functions,linear relaxation programming for linear multiplicative programming is established over a rectangle,and the proposed global optimization algorithm is proposed that can converge to the globally optimal solution.And finally the numerical experiments are given to illustrate that the proposed algorithm is effective and feasible.更多还原
