A new layout of the U-shaped automated terminal is more convenient to connect between and railway. In this study, a sort cluster scheduling method for multiple equipment yard railway proposed. The innovation points are as follows: (1) Considering that rail gantry crane (RGC), intelligent guided vehicle (IGV), double cantilever (DCRC) usually work in groups, they grouped cluster-scheduled. (2) h...

We propose a dynamic model for optimizing the ows of atcars that considers explicitly the broad range of complex constraints that govern the assignment of trailers and containers to a atcar. The problem is formulated as a logistics queueing network which can handle a wide range of equipment types and complex operating rules. The complexity of the problem prevents a practical implementation of a...

The logistics operation of container terminal can be exploded into several subsystems which are correlative, these subsystems connect by some handling facilities. This paper study the coordinated scheduling of three main kinds of facilities-Quay Crane(QC),Yard Truck(YT) and Yard Crane(YC), use multidisciplinary variable coupling design optimization method(MVCDO) to build YT coordinated scheduli...

Fix an odd integer d ≥ 1 and let Fd ⊂ R2 denote the real Fermat curve defined by the equation xd + yd = 1. Here we prove that Fd has the following property: Let X ⊆ Rn be any real algebraic variety. Then there exists a “one-parameter isotopic Nash modification” X̃t of X such that X̃0 = X and each real algebraic variety X̃t, t = 0 may be biregularly embedded into (Fd). Mathematics Subject Classific...

We consider the situation of rearranging freight trains in a shunting yard with a hump and several tracks. Here, an elementary shunting operation is to push a all cars of one track over the hump. On the way back to the tracks the cars can be guided individually to an arbitrary track. The goal is to create one or several trains that have their cars in a particular order. We measure the efficienc...
