Anonym2004, your model could be handled e.g by nonlinear/global optimization methods functions and packages. (I am the developer of MathOptimizer and MathOptimizer Professional.) If you are interested in a professional (commercial) solution, then please send along reasonably tight bounds for the parameters: these bounds are needed for all global solvers. If this is a one-time assignment, and you can provide at least minimal background regarding the need for solving this model, then I may do it as a courtesy. If you reveal your name, then I will acknowledge you for the example. Btw, your return address <anonym at bamboo.com> does not work... are we in some danger to solve this model? :-) Regards, Janos D.
