Retail price fluctuations, as well as uncertainties in demand, may lead to difficulties in deciding order quantities for retailers. This paper establishes an ordering model under two-stage price-fluctuation sales and derives the analytical expression of the optimal order quantity. An algorithm is given for solving the approximate optimal order quantity for the discrete model, and the convergence of the algorithm is proved. Through the investigation on the sales data of a man's T-shirt, Monte Carlo simulation is used to get enough price and demand random number pairs, so as to carry out simulation experiments. The results show that when price fluctuation is small, the retailer's optimal ordering strategy is relatively stable. However, when the retail price fluctuation exceeds a certain threshold, the retailer should reduce the optimal order quantity appropriately, so as to obtain higher profits; the approximate optimal order quantity decreases with the increase of the uncertainty of demand. The retailer should sell more products at the normal stage, thereby increasing profits under two-stage price fluctuation sales.
