摘　　要：本文研究的是按订单生产模式企业面对需求不确定条件下的生产决策问题.这类企业经常会遇到如下情形:客户的产品订单需求变动具有不可预期性,同时生产单批产品的固定成本较高,企业在承担一定的延期惩罚费用的条件下可以延期交货.因此需要考虑采用某种适当的生产策略来减少成本损失,即需要研究在未来产品订单需求不确定的条件下确定在什么时间对哪个产品进行生产使得总的固定生产成本及延期惩罚成本最优的决策问题.以往的研究一般都是假设包括订单到达时刻和订单需求量等需求信息是随机波动的,而实际情况中这些信息常常是不可预测且不能用概率分布刻画的.因此,本文从占线理论出发考虑了未来订单需求信息未知情形下的最优生产决策问题,构造了相应的数学模型,设计了一个竞争策略,证明了其具有较好的常数竞争比.数值分析进一步验证了该策略的有效性.The production decision-making of a Make-to-Order enterprise in which the demand is uncertainty is studied. Such enterprises frequently face a scenario that the customer’s product order demands varies unpredictably over time,while the set-up cost for producing a single batch of products is high,but enterprises can delay the delivery by paying some delay penalty. An appropriate production strategy to reduce the cost loss,i.e.,the decision-making of when to produce which product under uncertain future order demand to optimize the total set-up production cost and delay penalty cost should be of crucial importance. Previous studies have generally assumed that demand information,including order arrival time and order size,fluctuates randomly.However,in reality,such information is often unpredictable and cannot be characterized by probability distribution. Therefore,this paper considers the optimal production decision-making in the case of unknown future order demand from the perspective of online theory. A corresponding mathematical model is constructed,and a competition strategy is designed. It is proved that there is a superior constant competition ratio. Numerical analysis further validates the effectiveness of the strategy.
