多種生產週期時間產品之定價策略

Abstract

晶圓代工廠中，顧客對產品交期之急迫性有不同的需求。交期急迫性的訂單，以往皆以緊急插單方式進入生產線，此種插單方式會造成生產線的管理失序，且代工廠往往不知其代價。本研究將顧客對多種生產週期時間產品之需求納入接單管理之規劃，進而探討不同生產週期時間產品對產出及生產週期時間的影響，將此影響反映在相對價格上。 本研究在產品組合給定的情況下，發展系統化的方法訂定各種產品合理的生產週期時間及其產出；另考慮插入短生產週期時間產品對生產績效之影響，並訂定各種生產週期時間產品之相對價格。

This research proposes that IC foundries can provide multiple cycle time product service in order to meet the customer requirements. Multiple cycle time product service is that, wafer lots are assigned different committed manufacturing cycle time based on customer’s demands. For example, wafer lots are groups into three classes: shorter cycle time lots, regular cycle time lots, and longer cycle time lots. Customers can place their orders with a particular cycle time and price. Based on this idea, this research proposes a systematic approach to determine various committed cycle time and the corresponding relative prices. This research uses the APS software, Adexa MCP, and the semiconductor manufacturing line simulator, ASAP, to determine the appropriate level of throughput and the reasonable committed cycle time with a given product-mix. Then, we use ASAP to analyze the impact of different percentage of shorter cycle time lots on the following cases: (1) the decrease of throughput with the given committed cycle time and a given delivery rate; and (2) with the given throughput, the decrease of lots that are made within the committed cycle time. Then we define a new committed manufacturing cycle time with that a given delivery rate can be satisfied. Based on these impacts, we can define the relative prices among various cycle time products.
