Rapid increasing logistics demands call for high efficiency delivery in cities. Effective city planning of distribution centers is crucial. This paper first analyzes the current situation and constraint of Shanghai distribution centers. Then investment proposal is made for Shanghai distribution center relocation. The facility site selection and layout plan are proposed, and the commitment is ca...

In this paper, we analyse the proper curve $\gamma(s)$ lying on pseudo-sphere. We develop an orthogonal frame $\lbrace V_{1}, V_{2}, V_{3} \rbrace$ along curve, pseudosphere. Next, find condition for to become $V_{k} -$ slant helix in Minkowski space. Moreover, another $\beta(\bar{s})$ pseudosphere or hyperbolic plane heaving $V_{2} = \bar{V_{2}}$ which \bar{V_{1}},\bar{V_{2}},\bar{V_{3}} \rbra...
