Comparative study on seru production . cases of Japan, USA, and China

本研究调查了日本、美国和中国的血清生产情况。在参观了许多工厂后，我们发现日本电子制造商面临着困难。我们证明了SERU是一个高度灵活、高效和敏捷的制造组织，它为工业带来了巨大的利益。应用seru系统是通过准时制组织系统（JIT-OS）实现大规模定制的一种方法。设计一个健壮的JIT-OS是成功管理一个串行系统的关键。我们表明，设计问题的JIT-OS是NP难的。本研究建构一个在随机生产需求与不确定产品型态下，以最大化期望利润为目标之动态准时制作业模式。通过详细的计算，我们得出结论，seru系统不仅是鲁棒的，但也可以在动荡的商业环境中繁荣。

This research investigated seru production situation in Japan, USA, and China. After visiting a lot of factories, we found difficulties fronted by Japanese electronics makers. We show that seru is a highly flexible, productive, and agile manufacturing organization, which has brought huge benefits to industries. Applying a seru system is an approach to achieve mass customization via a just-in-time organization system (JIT-OS). Design a robust JIT-OS is the key for successfully managing a seru system. We show that the design problem of a JIT-OS is NP-hard. This research constructs a dynamic JIT-OS model to maximize expected profit under stochastic production demands and uncertain product types. By detailed computation, we conclude that seru systems are not only robust, but can also prosper under volatile business environments.
