STOCK MANAGEMENT DEVICE MOUNTING REQUIRED AMOUNT CALCULATION METHOD FOR MAXIMIZING EXPECTATION VALUE OF SALES PROFIT

摘要

PROBLEM TO BE SOLVED: To calculate a required amount which maximizes an expectation value of sales profit, even when a sales possible period of a commodity is longer than one required period.SOLUTION: A function w(s) of a dead stock loss amount per one commodity is a monotone increasing function to a required amount s(s≥0) in a sales possible period and a demand distribution, and the function in which, the loss amount per one commodity which is a dead stock increases by monotone increase to the required amount, is used, thereby an approximate solution of a stock amount for maximizing an expectation value of the sales profit is determined by numerical calculation using an approximation method, one by one.
