Abstract

An operating support system includes a control unit having: accepting the specifications required for a new case; searching a second database based on the accepted specifications; obtaining past cases similar to the extent that the specifications meet predetermined standards; extracting a record of the obtained case from a first database; determining the coefficient by which the presence/absence value is multiplied as the side effect degree for the extracted record; calculating the optimized side effect degree for each task of the obtained record, by calculating the sum of values obtained by multiplying the presence/absence value by the side effect degree for the tasks, and by calculating the difference between the calculated sum and the evaluation value; and comparing the magnitude relationship between the calculated side effect degree and a predetermined threshold to output the task corresponding to the side effect degree, as the task that is omittable in the new case.

a control unit,

wherein the control unit includes the steps of;

accepting the specifications required for the new case;

searching the second database based on the accepted specifications to obtain past cases which are similar to the extent that the specifications meet predetermined standards;

extracting the record of the obtained case from the first database;

determining the coefficient by which the presence/absence value is multiplied for the extracted record, as the side effect degree;

calculating the optimized side effect degree for each task with respect to the obtained case, by calculating the sum of the values obtained by multiplying the presence/absence value by the side effect degree for each task of the extracted record, and by calculating the difference between the calculated sum and the evaluation value; and
