1. A user evaluation apparatus, comprising:
- a failure information storage to store a failure information counting result for a plurality of repaired machines having the same characteristics as a plurality of machines to be measured;
a repair rate calculation module configured to calculate repair rate estimated values for the respective repaired machines based on the failure information counting result;
a first storage to store the repair rate estimated values;
a measurement data receiving module configured to receive measurement data associated with usage statuses of the plurality of machines to be measured;
a second storage to store the measurement data;
a weight value determination module configured to determine weight values used to cancel differences of the repair rate estimated values among machines respectively for the plurality of machines to be measured;
a weight storage to store the weight values respectively for the plurality of machines to be measured;
a parameter determination module configured to determine parameters of a user evaluation model required to calculate a degree of usage influence so as to maximize a target function, wherein the target function is defined using the weight values, the measurement data, and the failure information counting result;
a fourth storage to store the parameters of the user evaluation model;
a user evaluation module configured to calculate the degree of usage influence using the measurement data and the parameters of the user evaluation model; and

Abstract
A user evaluation apparatus includes a parameter determination module which determines parameters of a user evaluation model required to calculate a degree of usage influence so as to maximize a target function. The target function may be defined using weight values, measurement data, and a failure information counting result. The apparatus also includes a user evaluation module which calculates and displays the degree of usage influence using the measurement data and the parameters of the user evaluation model.
