CAD SYSTEMS DATA ACCOMMODATION IN "CLOUD" OPTIMIZATION PROBLEM FORMALIZATION
It is considered formalized statement of optimization of the accommodation data of the system of CAD in the «cloud» according to the offered hierarchical representation of the structure complex CAD system in this article. The basic stages and problems of the decision of the given problem at several of the system organization levels are defined and described. Input data are declared. Required constraints are introduced in each stage of the optimization problem decision. Mathematical model of the data accommodation is designed for the relationship between levels of functional and hardware configuration and data fragments accommodation. It is chosen efficiency criterions and deduced a formula complex efficiency criterion for the problem of the optimization of the data accommodation in «cloud» hosts.
