Firstly, brief introduction about the concept of comprehensive transportation is given to indicate that comprehensive transportation is an open complex giant system, which thus MSA is applied to exploring its constructing in China. A group argumentation environment （GAE） is applied to facilitate group divergent thinking process about what the concerned topics are in the project and acquire qualitative hypotheses for meta-synthetic system modeling. A multi-agent system model is constructed to analyze competitive relations of passenger transport between railway and highway as a demonstration of modeling by rule, one of 6 strategies of meta-synthetic system modeling. An evaluation support system is developed to integrate a variety of indicators and their related measure methods by a framework of input-output-outcome of comprehensive transportation to facilitate consultants to monitor current state of operation and management of transport system and generate alternatives of a set of indicators to evaluate efficiency or effectiveness of the whole system or its elements on demand.展开更多

With an analysis of various impacts on support system, the spares demand rate forecast model is constructed. According to systemic analysis method, spares support effectiveness evaluation indicators system is built, and then, initial spares configuration and optimization method is researched. To the issue of discarding and con-sumption for incomplete repairable items, its expected backorders function is approximated by Laplace demand distribution. Combining the （s-1, s） and （R, Q） inventory policy, the spares resup-ply model is established under the batch ordering policy based on inventory state, and the optimi-zation analysis flow for spares configuration is proposed. Through application on shipborne equipment spares configuration, the given scenarios are analyzed under two constraint targets：one is the support effectiveness, and the other is the spares cost. Analysis reveals that the result is consistent with practical regulation;therefore, the model＇s correctness, method＇s validity as well as optimization project＇s rationality are proved to a certain extent.展开更多
