Abstract

Genetik Algoritma (GA) doğal seçim mekanizmasına dayalı olan ve çözüm dizilerinden oluşan bir başlangıç topluluğunu kullanan optimizasyon tekniğidir. Bu çalışmada, kafes sistemlerin minimum ağırlıklı boyutlandırılması için değer kodlaması kullanarak ayrık tasarım değişkenleri ile bir GA programı oluşturulmuştur. FORTRAN bilgisayar programlama dilinde yazılan bu GA programı gerilme, stabilite ve yerdeğiştirme sınırlayıcılarını dikkate almaktadır. Kafes sistemlerin analizi için Matris Deplasman Yöntemi kullanılmıştır. Oluşturulan GA programının etkinliğini göstermek üzere tasarım örnekleri çözülmüş ve elde edilen sonuçlar literatürde verilen sonuçlarla karşılaştırılmıştır. Bu çalışmadan elde edilen sonuçlar genetik algoritmada değer kodlaması kullanılarak hazırlanan programın kafes sistemlerin optimum tasarımında etkin bir şekilde kullanılabileceğini göstermektedir.

Abstract

Genetic Algorithm (GA) is an optimization technique based on mechanism of natural selection and uses a population consisting of solution string. In this study, a GA program by using value encoding with discrete design variables developed for the least weight design of truss structures is presented. GA program coded in FORTRAN includes stress, stability and displacement constraints. For the analysis of truss structures, Matrix Analysis of Structures is used. To demonstrate the efficiency of GA program, design examples are solved and results obtained in this study are compared with the results given in the literature. It is concluded that the program coded by using value encoding in genetic algorithm can be effectively used in the least weight design of truss structures.
