1. A method for evaluating operability of a completed appliance at a designing stage, comprising the steps of:

  • forming a function-operation correspondence table which includes functions that the completed appliance is supposed to have, operational parts to exert each of the functions, and a number of times each of the operational parts is actuated to exert each of the functions;

    finding a total number of times each of the operational parts is actuated to exert all the functions in a case where all the functions are selected one time each, by using the function-operation correspondence table;

    adding up all the total numbers of times;

    calculating a ratio of the number of times each of the operational parts is actuated to the total numbers of times all the operational parts are actuated to exert all the functions;

    finding unbalance of using frequencies among the operational parts, from the calculated ratio and the number of the operational parts; and

    evaluating the operability of the appliance, based on the unbalance found.
