【Abstract】 This paper presents the joint optimal product quantity model for manufacturing firms aimed to maximize profit, proves that object function is concave, and sets up the method for getting solution. In optimization model, Input Output model is used for analyzing the relationship between different demand items within manufacturing firms using Input Output model. The punish costs caused by difference between planning output quantity and stochastic demand is considered in object function.更多还原
