PROBLEM TO BE SOLVED: To accomplish sensitivity analysis and goal seeking on the basis of a balance structure describing file without entailing heavy workload.SOLUTION: A business feasibility analyzing device stores a balance structure describing file. The business feasibility analyzing device accepts cause variables and result variables the user designates out of variables contained in the balance structure describing file. Then the business feasibility analyzing device, assuming that other variables are fixed variables, displays a graphic pattern showing the relationship between the cause variables and the result variables. Also, the business feasibility analyzing device accepts the user's designation of target variables, searched-for variables and restrictive variables the user designates out of the variables contained in the balance structure describing file. Then the business feasibility analyzing device, assuming that other variables are fixed variables, calculates searched-for variables that the target variables need in order to take the target value.SELECTED DRAWING: Figure 7
