Progressive design methodology for complex engineering systems based on multiobjective genetic algorithms and linguistic decision making

Data mining for decision making in engineering optimal design

Often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. Instead it is obtained by some numerical analysis such as FE structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. Yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

Genetic Algorithms for Multiobjective Controller Design

Multiobjective optimization strategy so-called Physical Programming allows controller designers a flexible way to express design preferences with a ’physical’ sense. For each objective (settling time, overshoot, disturbance rejection, etc.) preferences are established through categories as desirable, tolerable, unacceptable, etc. assigned to numerical ranges. The problem is translated into a un...

Using genetic algorithms for investment decision-making

learning techniques, such as neural networks, genetic algorithms and fuzzy logic, are achieving more acceptance because of significant advances in information technology. Until recently, these computer algorithms were considered too timeconsuming and computationally hungry to be practical. During the past decade, however, a number of financial institutions have successfully applied these method...
