Abstract :
The main objective of the allocation algorithm to determine the proportion of the various parts of the site is to reduce the cost of shipping the piece. This study presents an algorithm to reduce the cost of data transfer when allocating parts is, in such a manner that First of all, parts of the of the site, it should be, second reduce the cost of transmission components sites should Third update costs for all components that are present at the site should be optimized, However, all the conditions for the transfer of part of the site is selected, so that the reliability and availability of the site increases. In this study, the assignment of parts to a site in a distributed database system is done using genetic algorithms, Efforts to reduce the cost of data transmission. To review and consider the advantages of the previous method, the initial population, we have tried to better optimality of previous approaches is the initial population And a genetic algorithm to select the best chromosome instead of two parameters, the three parameters used. Analytical study shows that the proposed algorithm to other algorithms, the benefits and availability of data and reduce costs in the allocation of parts.
