PROBLEM TO BE SOLVED: To provide a stock transition calculation method capable of preventing occurrence of excessive stock or short supply by calculating stock transition according to the situation.SOLUTION: The stock transition calculation method includes the steps of: selecting an arbitrary stock factor and a value of a stock factor (S302, S303); creating a flow graph (S304); extracting a frequency component of the flow graph (S305); calculating a difference between the frequency component of a flow graph of the stock based on past performance and a frequency component of the extracted flow graph (S306); extracting a major frequency component (S307); repeating the above steps until the amplitude of the calculated frequency component becomes equal to or lower than a certain value by adding or reducing the stock factor or by increasing or reducing the value of the stock factor (S308); and calculating the stock transition by using the values of the stock factor and the stock factor at that time (S309). |
