中文摘要：

一个先进的ATP订单承诺系统可以帮助企业有效增加客户订单承诺和履行的准确性,缩短订单交货期,进而提高客户满意度和企业核心竞争力。设计了一个面向供应链的ATP系统（SC-ATP）。与传统的ATP系统相比,其包含了三个核心模块ATP、CTP和PTP。首先分析了上述三个模块的相互之间的逻辑关系及各模块的计算方法,然后重点研究了双向CTP承诺算法的设计,并用具体的算例进行了验证。SC-ATP系统通过充分利用整个供应链的库存和空闲生产能力等信息完成客户提出的紧急订单承诺过程,可以确保承诺的准确性与可靠性。

英文摘要：

An advanced order promising system based on ATP can help enterprise to increase the accuracy of promising, to fulfill the customer orders, to reduce the lead time of the orders processing, and to improve the customer satisfactory and the enterprise core competitive power. In this article, an advanced ATP system for the Supply Chain（SC-ATP）, is designed. Compared with the traditional ATP system, the SC-ATP system has three main modules, which are ATP, CTP and PTP. Firstly the logic relationship among the three modules and their calculation procedures is analyzed,then the CTP algorithm is studied in detail, and finally it is verified by a numerical example. Using the inventory and the vacant production capacity of the whole supply chain for urgent orders form customers, this SC-ATP system can ensure the producer＇s promise much veracious and reliable.
