1. The process of optimization in the engineering design is considered as avery important and in the same time complicated task for engineers to dealwith.
2. The problems of this type are mostly nonconvex, nonlinear andcomputationally expensive, including several conflicting objectives. Solvingmentioned design optimization problems, which mostly referred to black-
box optimization problems, is not a simple task.3. Black-box optimization problems with multiple objectives can be solved in
several different ways. And there have been more than hundredsalgorithms developed
4. However most of these algorithms, due to some difficulties related to theusage, havent been applicable
5. we introduced the challenges and suggested the solutions , in particular inshape optimization
6. we introduced the effective methods and evaluate them via real-lifestudycases

As engineers would prefer to pick up and utilize the simplest
technique.
1.They do it by try and error (STMicroelectronics FP7 project end
June 2010) after performing an statistical approach
2. Recently focused on multiobjective optimization, Design SpaceExploration utilizing Design of Experience(DoE); I would call it anoptimization assisted try and error method

1. Utilizing statistical method of Design Space Exploration(DSE) by a tool calledM3Explorer , just 5000 points are selected and evaluated by the ST computer
farm simulator faculties and a Pareto optimal solutions including 10,000 pointsare suggested( it took 3days)
2. Utilizing the Design of Experience (DoE) algorithms, From the abovesimulations results evaluated the design space is reduced from 10,000 to 500
utilizing ( DoE)
