Method, program storage device, and apparatus for optimizing and analyzing efficiency of equipment

An apparatus for analyzing an equipment efficiency, comprising:

• a basic data database which stores performance loss times as basic data, the performance loss times corresponding to items independent of dynamic variables, the dynamic variables having values that change according to the operational environment of a provided equipment among a plurality of performance loss items modeled with respect to the provided equipment;
• an equipment simulator which receives values corresponding to the dynamic variables input by a user and the basic data from the basic data database, the equipment simulator capable of simulating the operation of the equipment, and calculating target values for the performance of the equipment;
• a surveyed value calculator which calculates surveyed values for the performance of the equipment from the measured actual equipment running time data of the equipment, the surveyed values corresponding to the target values for the performance of the equipment;
• and
• an evaluation output unit which calculates and outputting the gaps between the target values input from the equipment simulator and the corresponding surveyed values input from the surveyed value calculator.

A method for analyzing and optimizing equipment efficiency, the method comprising:

• subdividing equipment running time into a valuable operating component and at least two performance loss components;
