Abstract
The mine logistics transportation system with belt and surge links is often formed by a complex hybrid dynamic system that consists of continuous and discrete links, and these parts can have the complex changes along with the mining engineering going on. Studying the hybrid system with belt and surge links to fully realize its beneficial functions is very significant. Until now, there have been many references studying the logistics transportation hybrid system with belt and surge links, and many concepts about it have been set up. However, in these references, complicated real-time dynamic changes of the hybrid system usually is studied. This paper presents a novel approach to study real-time dynamic optimization analysis and simulation problems of complex mine logistics transportation hybrid system, which can be used to make optimization design for this kind of complex hybrid system. The proposed method considered expressly complicated real-time dynamic changing of the hybrid system comparing with some existing references and can solve some optimization design problems of the hybrid system. In addition, this paper used statistical data of a real logistics transportation system with belt and surge bin on simulation and gets some useful conclusions. The application result shows that the presented method is valid.

Links behind bin can continue transporting logistics of bin when links ahead of bin are in failure; on the other hand, links ahead of bin can continue transporting logistics to bin when links behind bin are in failure
Summary
In complex mine logistics belt transportation system, surge links are often set. The mine logistics transportation system with belt and surge links is often formed by a complex hybrid dynamic system. Setting surge bin can reduce the interacting of links ahead and behind bin to improve reliability of the whole hybrid transportation system. Where 1 is links ahead of bin, h is surge bin, and 2 are links behind bin. The function of surge bin can be discussed as follows. Setting surge bin can reduce the interacting of links ahead and behind bin to improve reliability of the whole transportation system. (2) Setting surge bin can buffer transporting flows to keep the uniformity, that is, can cut down high transporting flows and can fill up low transporting flows. (3) By setting surge bin, logistics can be classified and neutralized.
