<p><P>PROBLEM TO BE SOLVED: To automatically decide the lowest-price system configuration of a computer having necessary processing performance in a short period of time. <P>SOLUTION: The system configurations are expressed by four parameters (CPU performance, the number of CPUs, a main storage capacity, and I/O processing speed). The most inexpensive four parameters are derived through the use of a numerical solution by Lagrangian indterminate multiplying method, etc., under a fixed restricting condition concerning the response time of a transaction processing. Besides, the number of jobs to be simultaneously performed by one of the CPUs arranged in the system is also optimized. As shown in Fig., the system configuration is derived, by which the minimum price is obtained, and probability of the response time being not less than A is not more than B. <P>COPYRIGHT: (C)2004,JPO</p> |
