针对一类有保鲜期的易腐品——时滞变质物品,考虑需求受价格、广告投入及存货陈列量的影响,在允许缺货和不同的短缺量拖后率下建立该类物品的库存与运输联合优化模型,并针对模型特点设计出一种启发式算法,从而得到最优库存策略及运输策略。给出算例,利用MATLAB7的最优化求解功能容易求出模型的最优解。结果表明：引入由价格、广告和存货陈列量共同决定的需求率,不仅更符合实际,而且有利于将复杂模型转化为关于多项式的问题来处理,大大降低了求解难度,同时节约了求解时间。

The inventory and transportation integrated optimization problem for deteriorated goods is addressed.To make the study applicable to reality,it considers that demands are affected by price,advertisement investment,and displayed stock level（DSL）.Under the assumptions that shortage and backlog with a variable rate are allowed,a mathematical model is presented for this problem.Based on this model,a heuristic is proposed to solve the problem.With the help of MATLAB 7,a numerical example is given to show the application of the proposed method.Result shows that the proposed method is not only more realistic than the existing ones,but also makes the problem solvable by polynomial algorithm.
