Information processing apparatus, information processing method, and non-transitory computer readable medium

An information processing method comprising:

• providing a data set including
• a plurality of first pairs each including both a set value and an evaluation value, the set value being a value set for a parameter of a system in operation or a product to be manufactured and the evaluation value being a value obtained by evaluating a result of testing the system or the product where the set value is set for the parameter or
• a plurality of second pairs each including both the set value and an evaluation value variation obtained in a case where the set value is set for the parameter in the system or the product wherein the evaluation value variation indicates a variation of respective evaluation values obtained in a case where a plurality of values included within a neighborhood range of the set value are set for the parameter in the system or the product, the neighborhood range including a first range of values larger than or equal to the set value and a second range of values smaller than the set value;
• estimating a first relationship expression expressing a relationship between the set value and the evaluation value variation based on the data set, or estimate a second relationship expression expressing a relationship between the set value and the evaluation value and a third relationship expression expressing a relationship between the evaluation value and the evaluation value variation;
• determining, based on the first relationship expression or a pair of the second relationship expression and the third relationship expression, a recommended set value which is a set value recommended to a user for the parameter in the system or the product;
• and
• outputting the recommended set value visibly to the user,
• the method further comprising
• iterating processes until a termination condition is satisfied, the processes including
• acquiring an evaluation value by evaluating a result of testing the system or the product for which the recommended set value to the user is set to the parameter,
• updating the data set using the recommended set value and the acquired evaluation value, and
• estimating the first relationship equation or estimating the second relationship expression and the third relationship expression using the updated data set, and
• determining a recommended set value which is a set value recommended to the user, and
• selecting, when the termination condition is satisfied, an optimum set value to be set for the system or the product from among a plurality of set values that have been set for the parameter of the system or the product so far, based on the evaluation value variation corresponding to each of the plurality of set values, wherein the selected optimum set value is set to the system or the product.

A non-transitory computer readable medium storing a program that causes a computer to perform a method comprising:

• reading, from a memory, a data set including
• a plurality of first pairs each including both a set value and an evaluation value, the set value being a value set for a parameter of a system in operation or a product to be manufactured and the evaluation value being a value obtained by evaluating a result of testing the system or the product where the set value is set for the parameter or
• a plurality of second pairs each including both the set value and an evaluation value variation obtained in a case where the set value is set for the parameter in the system or the product wherein the evaluation value variation indicates a variation of respective evaluation values obtained in a case where a plurality of values included within a neighborhood range of the set value are set for the parameter in the system or the product, the neighborhood range including a first range of values larger than or equal to the set value and a second range of values smaller than the set value;
• estimating a first relationship expression expressing a relationship between the set value and the evaluation value variation based on the data set, or estimate a second relationship expression expressing a relationship between the set value and the evaluation value and a third relationship expression expressing a relationship between the evaluation value and the evaluation value variation;
• determining, based on the first relationship expression or a pair of the second relationship expression and the third relationship expression, a recommended set value which is a set value recommended to a user for the parameter in the system or the product;
• and
• outputting the recommended set value visibly to the user,
• the method further comprising
• iterating processes until a termination condition is satisfied, the processes including
• acquiring an evaluation value by evaluating a result of testing the system or the product for which the recommended set value to the user is set to the parameter,
• updating the data set using the recommended set value and the acquired evaluation value, and
• estimating the first relationship equation or estimating the second relationship expression and the third relationship expression using the updated data set, and
• determining a recommended set value which is a set value recommended to the user, and
• selecting, when the termination condition is satisfied, an optimum set value to be set for the system or the product from among a plurality of set values that have been set for the parameter of the system or the product so far, based on the evaluation value variation corresponding to each of the plurality of set values, wherein the selected optimum set value is set to the system or the product.
