Note—Comment on “A Perturbation Scheme to Improve Hillier's Solution to the Facilities Layout Problem”
指出Picone和Wilhelm解决的三个设施布局问题与Nugent等人的测试问题不同，因此与其他研究者的结果比较无效。
This note points out that three of the facilities layout problems solved by Picone and Wilhelm (Picone, C. J., W. E. Wilhelm. 1984. A perturbation scheme to improve Hillier's solution to the facilities layout problem. Management Sci. 30 1238–1249.) are different from the test problems given in Nugent, Vollmann and Ruml (Nugent, C. E., T. E. Vollmann, J. Ruml. 1968. An experimental comparison of techniques for the assignment of facilities to locations. Oper. Res. 16 150–173.). Comparison with results obtained by other researchers to these test problems is, therefore, not valid.
