Study On Harmonious Of Maritime Dangerous Chemicals Transportation System

As to dangerous chemicals transportation, merchant service has been taking a major part of cross-country, cross-regional carriage. The nature of the dangerous chemicals and the complex shipping environment will inevitably increase the risk to the cargo transportation. Generally, the transportation system of the dangerous chemicals consists of five sub-systems (human, ship, cargo, environment and the management) which are affected by several indexes. Under the nonlinear interaction, the difference of the sub-systems and the indexes can generate the negative effect which affects the safety of the cargo transportation. In connection with the cause of the negative effect in question, this paper studied the systematic compatibility from the view of the theory of harmony in order to enhance the transportation safety.For the purpose of eliminating the effect from the difference of the elements of the transportation system, this paper studied "the synergy of cargo" and "the harmony of human", based on which, the concepts of the emergence mechanism and synergic evolution mechanism were put forward, and then, the synergic evolution mechanism diagram was got; also, this paper studied the harmony of the transportation system while in process of concertedness coherence, proposed the idea of the harmonious mechanism of the dangerous chemicals transportation, and then drew the harmonious mechanism map of the transportation system.In view of the theory of harmony, the harmony of a system can be divided into composition harmony, organization harmony, internal harmony and external harmony, and based on which, the measure model was built up; in order to explain the evolutionary process of the systematic harmony states, the idea of the harmonious quadrilateral rule was brought up and the criteria were obtained; in connection with the characteristics of the dangerous chemicals transportation system, the assessment index system was built up, and each single index value was obtained by structuring membership functions of indexes; in order to get the overall harmony degree within certain space and time, a matrix of systematic harmony was constructed; also, this paper made MATLAB simulation to the harmony value for different space and time, receiving images of the harmony states of the transportation system while at sea, and proving that the harmony states has a strong connection with the safety of the system.This paper, from the view of the entirety of a complex system, studies the system of the dangerous chemicals transportation based on synergy theory, nonlinear theory and the harmony theory, replenishing the previous study on the dangerous chemicals transportation.
