一般生產者訂定規格的方法其考慮的對象僅及於自身,考慮的成本也
僅及於規格外不良品成本,故其所訂出的規格通常僅供自己檢驗之用,消費
者則另有一套檢驗規格,如此一來將造成雙重的檢驗成本,而且規格的功用
也會大打折扣. 基於上述的原因,本文擬應用品質損失函數和動態法訂
出一套應用於自動化連續生產系統之規格(所謂的動態法就是對變動的分
配訂定規格).本研究所建立之規格具有三項特色(創新),一 由於同時考慮
生產者及消費者在規格內規格外損失之成本,故此一規格不但為生產規格,
同時也是出廠檢驗規格(消費者進料檢驗規格).二 本套規格模型除了能導
求連續特性值,離散特性值之單一特性值外亦能同時導求雙特值規格.三
由於應用動態法之故,本套規格模型除了能導求出最小成本之輸入信號.
本文最後除了對金屬工業研究發展中心所發展中心所研究之自動澆鑄機實
例探討外,另外也對每一種生產情形之規格模型做範例探討得到一些結果,
祈能對工業界有所貢獻.

In general , establishment of specifications for a
manufactured products a matter of cost . The cost considered is
only related to producer's defect products . Traditionally ,
Consumer's loss is not included . The specifications thus far
defined is only utilized as outgoing inspection is set by
consumer themselves . Thus , we wolud like to use quality loss
function develoved by Dr. Taguchi to construct the
specifications for both producer and consumer simultaneously .
This paper studies the establishment of specifications for an
automatic die-casting system developed by Metal Industries
Research & Development Center (MIRDC) . IN Kaohsiung , Taiwan ,
R.O.C. Two characteristics of the quality measures are
considered , one is continuous type with normal distribution ,
the other one is discrete type with poisson distribution . Due
to the fact that the signal given to the automatic system is
dynamic , we develop a cost model related to the dynamically
changed data (continuous) . Minimizing that cost model , we find
the optimal specifications (signal) for the system . Examples
Are given to illustrate the model developed . Finally
verification is also made to ensure the specifications are
valid.
