傳統上，因為受限於資訊系統的透通性，通常是採用接單後才進行資源需求計劃，這樣子的接單風險則相對便高，除非是有很高的庫存否則準時交貨的機率不高。為了使訂單的回覆能更可靠更快速，本文採用所謂的進階訂單允諾的方法，將接單作業與資源需求規劃作結合；也就是將前端的訂單允諾與後端的訂單滿足的結合在一起。首先，採用主規劃的方法，預先做好資源需求規劃模擬成可以承諾顧客的數量，即配置可允諾量(AATP)。不同於傳統ATP只針對未承諾的完成品作允諾，本論文是以整個供應鏈能力為基礎來答覆訂單的數量與交期。同時，針對資源短缺狀況提供資源彈性策略，如供應商替代；在訂單允諾的接單策略上，亦針對顧客喜好提供訂單彈性策略，如替代品與部分達交策略。最後，經由模型的建構與情境模擬之驗證，這些方法與策略的使用可以提高顧客回應能力，使回覆更可靠更快速，同時也能提高公司的利潤。

Traditionally, because of the limited transparency of information system in each department, we perform the Resource Requirement Planning when received orders. In that case, the risk of receiving an order is relatively high. Unless the company has very high level inventory, the probability of “on time delivery” will be low.
In this paper, we use the methods and tools called Advanced Available to Promise to enhance order promising responsiveness and order fulfillment reliability. The traditional ATP only can search for uncommitted finished goods and decide whether to give a promise to the customer or not. Now, we can promise quotes based on capabilities of supply chain. Besides, we also add some strategies in case of shortage of finished goods or supply chain resources. The major goals are (1) the improvement of on time delivery by generating reliable quotes, (2) the reduction of number of missed business opportunities by searching more alternative ATP, (3) enhancement of revenue and profitability by categorizing customer relationships.
