Therefore, this paper analyses changes in behavioural routines and governance structures in the maritime transport chain using a case study that depicts mutual projections of expected container transhipment moderated by a neutral third for reducing the uncertainty in planning within the whole maritime transport chain. The actors' different views on container transport are collected and directly confronted to an expert panel showing bounded rationality and thus asymmetric information can be circumvented The planning approach shows how actors' different internal planning can be improved and evident to the market. The whole maritime transport chain expects the future development in container transport which can be given by using collaborative Delphi-based planning. As a result, an overall picture for planning issues can be constituted, improving both individual planning of the actors and expected market growth.展开更多

The geometric state of the caisson, the stress of upstream and downstream anchorage cables, underwater topography, the drag forces of the caisson cutting edge and frictional resistances of the sidewall and etc. are monitored in real time. According to the synthesized data analysis and decision-making system, the spatial states of the caisson are adjusted in time to locate and embed the deep water caisson precisely. The offset error of the caisson is less than 30 cm and the vertical error is 1/363 at the final stage. The control technology for construction of large caisson under deep water is concluded and would be helpful for the construction of bridge foundation in the future.展开更多

It is well known that there are n disjoint paths connecting any two nodes in an n-dimensional hypercube (n-cube for short). In order to enhance the performance and reliability, several variants of n-cube networks have been proposed. The enhanced hypercube networks (denoted by Qn,k) is one of these variation. In this paper, its structural natures are obtained in detail and its properties and performance have been analyzed. The minimum transmission delay of enhanced hypercube Qn,k has been proved equal to k +q┌n-k+1/2┐.The one-to-one routing process is also concerned, this paper also proves that' thereexists n + 1 internally-disjoint paths between any two distinct nodes in Qn,k for k = 2. It follows that its connectivity and edge-connectivity are n + 1.展开更多

First, we briefly present (1) the general process of pre-embodiment design with SMFs, (2) the procedures of creating genotypes and phenotypes of SMFs, (3) the specific procedure of instantiation of phenotypes of SMFs, and (4) the procedure of system model management and processing. Then, the chunks of information needed for instantiation of phenotypes of SMFs are discussed, and the ISCs designed for instantiation presented. Afterwards, the information management aspects of system modeling are addressed. Methodologically, system modeling involves (1) placement of phenotypes of SMF in the modeling space, (2) combining them towards the desired architecture and operation, (3) assigning values to the parameters and checking the satisfac- tion of constraints, and (4) storing the system model in the SMFs-based warehouse database. The final objective of the reported research is to develop an SMFs-based toolbox to support modeling of cyber-physical systems (CPSs).展开更多

In this paper a maiden adoption of the matter-element is applied to combine with information entropy theory to analyze distributing the railway refrigeration container handling stations based on concerned literature and historical data, and a multi-objective decision-making model on analyzing distributing the railway refrigeration container handling stations is set up based on matter-element and extension model. Based on establishing sutra field and controlled field, we apply relating function of matter- element and extension set to get relating function value of the railway refrigeration container handling stations. Finally a case study is carried out to verify the validity, objectivity and applicability of this model through calculated and compared with traditional analysis methods. Practicality application indicates that this method can avoid subjectivity of weighting, but enhance the extensibility, the model mentioned above has guiding significance and applied value for analyzing distributing the railway refrigeration container handling stations.展开更多
