The dynamic production scheduling is a very complex process that may arise from the occurrence of unpredictable situations such as the arrival of new orders besides the ones already accepted. As a consequence, companies may often encounter several difficulties to make decisions about the new orders acceptance and sequencing along with the production of the existing ones. With this recognition, a mathematical programming model for the regenerative scheduling problem with deterministic processing times is formulated in the present paper to evaluate the economic advantage of accepting a new order in an engineer to order (ETO) manufacturing organization. The real case of an Italian ETO company which produces hydraulic marine and offshore cranes is afterwards presented.

动态生产计划是一个非常复杂的过程，它可能是由于不可预知的情况（例如已经接受的新订单的到来）的出现而引起的。结果，公司可能经常会遇到一些困难，难以就新订单的接受和排序以及现有订单的生产做出决策。有了这种认识，本文针对具有确定的处理时间的再生调度问题建立了数学编程模型，以评估在工程师对订单（ETO）制造组织中接受新订单的经济优势。随后介绍了一家意大利ETO公司生产液压船用和海上起重机的真实案例。
