摘　　要：由于现实生活中有些特殊商品(如彩电,计算机等),在被市场逐步认同的过程中,需求率是呈线性递增的,由于科技日新月异,产品很快推陈出新,顾客对此类商品的需求当呈线性递增到一个顶峰的时候会逐步减小,但周期内需求减小的速度是先减小的很快,然后慢慢变小[1].故本文对需求率随时间分段变化的库存模型分段建模和求解。In the real life,the demand rate for some special products（such as color televisions,computers,etc.） is linear-increasing in the process of gradual market identification.The technology has been making continuous progress,products develop new from the old very quickly,and the demand of the customers increase linearly to the peak time then will be gradually reduce.However,the reduced speed decreases rapidly at first in the period,and then becomes slow.Therefore,this paper is demanded for modeling and solving the inventory model of demand rate in time segments.
