Retracted

Mathematical Problems in Engineering has retracted this article. The article was found to contain a substantial amount of material, without citation, from the following published article: “Cho, B. R., Choi, Y. & Shin, S. Int J Adv Manuf Technol (2010) 49: 839. doi:10.1007/s00170-009-2455-3” [2]. The authors stated that the previous article used censored data and the current article used noncensored data, which require different techniques to manage. The authors say that in the previous work, type 2 right-censoring schemes were developed and implemented in the robust design context, and thus the basic goals posed and the methods developed in the articles are entirely different. However, much of the text of the articles is the same, including most of the Introduction, Section , and Conclusions and parts of Sections and .
