Some mathematical properties of a DEA model for the joint determination of efficiencies
收藏 引用
JOURNAL OF THE OPERATIONAL RESEARCH SOCIETY 1997年 第1期48卷 51-56页
作者: Molinero, CM Tsai, PF The University of Southampton
This paper explores the Kuhn-Tucker conditions and convexity issues in a non-linear DEA model for the joint determination of efficiencies developed by Mar Molinero. It is shown that the usual convexity conditions that... 详细信息

Allocating tolerances to minimize cost of nonconforming assembly
收藏 引用
ASSEMBLY AUTOMATION 1997年 第4期17卷 303-+页
作者: Wei, CC Chung Hua Polytech Inst Dept Ind Engn & Management Hsinchu Taiwan
Tolerance assignment plays a vital role in reducing the manufacturing cost, and most optimization models for assigning the tolerances lend to ignore the process capability of the machine. Therefore, the quality loss d... 详细信息
