考量交期及價格相依之需求訂定最適允諾交期及其價格

Abstract

顧客可依其對允諾交期和價格的偏好來分類，第一類顧客較注重產品允諾交期，而另一類顧客較重視產品價格。廠商可依不同類型顧客的需求，提供多種生產週期時間品服務，以提昇廠商收益。考量工廠的產出量與生產週期時間的關係，如何對兩類顧客分別訂定最適當的允諾交期和價格以最大化公司利潤，是值得廠商思考的課題。 本研究探討接單式生產的工廠面臨兩類顧客需求時，該如何訂定允諾交期與價格的問題。本研究，在已知客戶對價格及交期的偏好函數及工廠產能限制下，以最大化公司利潤為目標，構建利潤模式，以訂定兩類顧客最適單一允諾交期與價格。本研究另依客戶類型，構建利潤模式，分別訂定各類型客戶的最適允諾交期與價格，以最大化公司利潤。

This research presents a profit model to study time-based pricing policies for make-to-order manufacturing systems facing two types of customer demand. One type of customer demand is lead-time-sensitive and the other type of customer demand is price-sensitive. Each type of customer demand is denoted as a function of price and lead-time. In order to meet customer demand for each type, manufacturer might provide multiple lead-time services with different prices. The difference between these prices is relevant to the loss of throughput to shorten manufacturing cycle time for lead-time-sensitive customer demand. However, to define the relationship between throughput and manufacturing cycle time is difficult. In this research, we use simulation model to find the relationship between throughput and manufacturing cycle time. Based on this relationship and the given customer demand functions, we solve the proposed profit model to determine the appropriate committed lead-time and price for each type of customer demand, respectively.
