dc.description.abstract一個晶圓代工廠的機台組合指的是工廠對產能的規劃及配置,換言之,工廠要決定機台種類及機台數量。對晶圓代工廠來說,因為機台非常昂貴,機台組合決策是一個相當重要的問題。以往的文獻大多將焦點放在,如何在預算限制下,最大化工廠產出量。然而,在晶圓代工廠中,週期時間是一個相當重要的績效指標,卻很少有文獻探討如何在及台組合決策中考慮週期時間限制的問題。 本研究的目標是建構晶圓代工廠機台組合及數量的決策機制。本機制的輸入條件包括(1) 產品組合或需求型態,(2) 產出限制或最低產出率,(3) 產品週期時間限制或最長平均週期時間。本研究的結果會產生一組機台組合及每個工作站的機台數量。這個機台組合不僅能夠在既定的產品組合之下,滿足上述兩個生產績效限制條件,還能夠使購置機台的成本最小化。 本文運用基本的空間搜尋演算法,配合四種簡單的規劃方法,找出晶圓代工廠應有的機台組合。測試結果發現,在這四種方法中,最佳和最差的機台組合在成本上的差距,可能會高達30億台幣以上。zh_TW
dc.description.abstractA machine-mix configuration denotes a factory capacity implementation plan which describes the number of machines and machine types for the factory. Determining machine-mix configuration is a very important problem for an IC foundry because the machines are quite expensive. Most previous studies on machine-mix configuration focus on developing methods for maximize throughput under budget constraints. In an IC foundry, short cycle time is a very important justification criterion, yet rarely included in previous relevant studies. The objective of this research is to develop a decision-making mechanism for designing the machine-mix configuration for an IC foundry. The input to the decision-making mechanism involves (1) product mix or demand pattern; (2) throughput constraint or the lowest production output rate; (3) cycle time constraints or the longest mean cycle time. The output tends to give a set of machine types and corresponding machine numbers which would satisfy the above two constraints in producing the given product mix, under the criterion of minimizing total investment. A basic design method together with four embellishments have been developed and tested. Testing results show that among the four proposed machine-mix configurations, the difference between the best and the worst solutions can be around 10 Million US dollars.en_US
