Abstract: In order to improve the satisfaction of resources allocation of cloud manufacturing platform designed for manufacturing demand,a mathematical optimization model with the target of eliciting the manufacturing-quality,the manufacturing-cost,the manufacturing-time and the resource-utilization rate was presented based on the analysis of cloud manufacturing platform and related manufacturing resources virtualization and the consideration of the actual manufacturing production processes and manufacturing units.And the reasonable and practical model validated by the genetic algorithm that is sensitive with parameters with different genetic parameters has provide a solution for the problem of manufacturing resources allocation.

Key words: demand, cloud manufacturing, resources virtualization, resources allocation, genetic algorithm
