Note—Comment on “The Dynamics of Plant Layout”
为Rosenblatt（1986）研究的动态工厂布局问题建立了一类最佳可能的上界，使用原论文的符号体系。
This note establishes a class of best possible upper bounds for the Dynamic Plant Layout Problem (DPLP) examined by Rosenblatt (Rosenblatt, M. J. 1986. The dynamics of plant layout. Management Sci. 32 76–86.) in this journal. We use the notation of that paper.
