With China's rapid economic development, electricity supply is relatively shortage, and the contradiction of power coal supply and demand is prominent. In this context, using WITNESS logistics software platforms, this paper establishes a simulation model about a power coal ocean shipping logistics system of a transshipment port as the center, focusing on how to make full use of the existing res...

Infectious waste disposal is a crucial concern in many areas. Not only the obnoxious, but it can also pose vital risk to human health. Disposal of infectious incurs higher costs than general and must abide by stricter regulations. In this paper, formulated as multi-objective optimization model. The objectives encompass economic, social, environmental concerns. To save cost, transshipment facili...

A transshipment problem with demands that exceed network capacity can be solved by sending ow in several waves. How can this be done in the minimum number of waves? This is the question tackled in the quickest transshipment problem. Hoppe and Tardos 10] describe the only known polynomial time algorithm to solve this problem. Their algorithm repeatedly minimizes submodular functions using the el...

A new method namely, splitting method is proposed for finding an optimal solution to a transshipment problem in which all parameters are real intervals. With the help of a numerical example, the proposed method is illustrated. The splitting method is extended to fully fuzzy transshipment problems. Mathematical Subject Classification: 03E72

We consider an inventory model for spare parts with two stockpoints, providing repairable parts for a critical component of advanced technical systems. As downtime costs for these systems are huge, ready-for-use spare parts are kept on stock, to be able to quickly respond to a breakdown of a system. We allow for lateral transshipments of parts between the stockpoints upon a demand arrival for a...

In this paper, we address the optimal joint control of inventory and transshipment for a firm that produces in two locations and faces capacity uncertainty. Capacity uncertainty (e.g., due to downtime, quality problems, yield, etc.) is a common feature of many production systems but its effects have not been explored in the context of a firm that has multiple production facilities. We first cha...

Cross-border logistics is an important support for the rapid development of cross-border e-commerce. This paper expounds e-commerce and its status explores problems existing in distribution, such as high cost, low level information, credit evaluation system being not perfect, professional personnel shortage. Advanced cloud distribution mode introduced into logistics, network model built using p...

What is the best distribution strategy to ship materials from a source to multiple destinations on a regular basis? This is a common question confronting logistics planners in many industries. This paper examines this issue in the context of the ocean freight industry. In particular, we tackle the economics of freighting raw materials through a transshipment hub, and propose a method to synchro...

In modern rail-rail transshipment yards huge gantry cranes spanning all railway tracks allow for an e cient transshipment of containers between di erent freight trains. This way, multiple trains loaded with cargo for varying destinations can be consolidated to a reduced number of homogeneous trains, which is an essential requirement of hub-and-spoke railway systems. An important problem during ...
