چکیده
The paper deals with the distributed solution of simulation based nonlinear constrained optimization problems in engineering on a network of workstations. This type of non-linear optimization and control problems in engineering can be generally characterized as non{convex and non-smooth. Additionally, the involved simulation introduces certain numerical "noise\ to the solution process. These characteristics lead to very time consuming solution processes, because of long{running computations for simulation and the dif-culties in nding a global optimum. The resulting requirements for the corresponding software architecture and software integration of the simulation and optimization components are discussed. The implementation of this software architecture is presented using the OpTiX system for optimization , the nite-element package FEFLOW for simulation , and the Winner resource management system for load distribution in networks of workstations. Using this system, a test problem is solved to demonstrate the beneets of load distribution, and industrial applications from engineering are used to show the feasibility of the proposed distributed approach.
