As on the stage systems and networks operation, part of the parameters which are taken into consideration in the design process change its meaning, the project formed earlier can not satisfy the requirements. It is necessary to respect a variability at the time of selected system or network characteristics in the design process. The authors propose a method introducing an indeterminacy to the design process: design criteria, input parameters and model itself. It allows to obtain not one but a set of design solutions which specify given requirements and it is possible to take a human factor into consideration in the solution search process. Systems and networks change incessantly their parameters in the evolution process. With reference to the systems these changes involve mainly increase of system capacity which is essential for solving of computational tasks with the higher and higher complexity. The changes observed in the networks are related to the increase of communication channel capacity. These changes allow to use the new services in the networks and those of multimedial transmission (1). Until recently the basic method of capacity computer systems characteristics improvement was the increase of running rate elements base. With time it turned out that the results obtained in this way are insufficient. Therefore structural methods of capacity improvement based on using parallel processing found application. These methods, owing to combination of many computational elements with the aid of additional partition and task migration procedures allowed to increase computer system capacity. Along with the increasing frequency of process elements working in the computer systems, the new problem has appeared - communication problem between the processing elements. In the modern parallel systems, the information transmission times between the system components were surpassing delays resulting from the computation process (1). In the case of computer networks the basic restrictions were a result of coarse-grained computational tasks granulation and thus of significant |
