Optimal design assistance device, method, and recording medium

A non-transitory computer readable medium that stores therein a computer program when executed by an optimal design assistance device causes the optimal design assistance device to perform a method of assisting in designing controllable design parameters of a computer system to which a plurality of Service Level Objects (SLOs) defining non-functional requirements of the computer system are specified, the method comprising:

• deriving a minimum value of a price of a system configuration of the computer system, as a relaxation solution evaluation value, by using a part of the SLOs, the relaxation value being determined at high speed without simulation;
• searching for a parameter set of design parameters using the derived minimum value of the price, which achieves all of said plurality of SLOs and minimizes the price of the system configuration;
• comparing the relaxation solution evaluation value with the minimum value of the price of the system configuration set in advance;
• and
• searching for the parameter set when the relaxation solution evaluation value is smaller than the minimum value of the price of the system configuration set in advance.
