【摘要】：目前我国经济发展存在不均衡的状况,这主要是由我国广阔地域上的差异性物流通道造成的。中西部地区普遍缺乏便捷的国际物流通道,使物流成本无形中增加,进而降低了其出口商品的竞争力,这是造成中西部地区发展落后和制约其经济发展的主要原因。国际陆港的建立对中西部地区意义重大,有助于发展对外贸易,打通与国外的物流通道,增强优势产品的国际竞争力;另外,从国家层面来说,在内陆地区建立国际陆港,有助于推进中部崛起及西部大开发等战略举措的实施。国际陆港所构成的物流系统是一个不断变化与发展着的系统,需要多部门进行多极参与。企业在体现整个系统的合力中饰演着不可或缺的角色,物流企业在国际陆港的形成和发展中发挥着积极重要的促进作用,同时也是促进国际陆港中各类集成力形成合力的关键所在。港区内的物流企业进行联盟,有利于相互进行资源互补,协同运作等。这样,就可以使联盟体形成一种集成力,提升了物流企业联盟整体在国际陆港中的竞争力。首先,本文从定义、特征以及功能等方面对国际陆港和物流企业联盟进行了梳理,分析了国际陆港及物流企业联盟的发展现状和未来发展趋势,并对国际陆港视角下物流企业联盟的必要性进行了分析。其次,基于层次分析法和遗传算法,通过对国际陆港的理解和对相关文献的阅读,确定了国际陆港中物流企业联盟伙伴的选择影响因素,从宏观的层面上确定了影响因素的指标评价体系,经过层次分析法的处理并与遗传算法相结合构造出了适应度函数,采用MATLAB仿真软件,搜寻到了适合联盟的物流企业。再次,基于元胞自动机的理论,模拟了国际陆港中物流企业之间组成的复杂系统,将各个影响因素转化到元胞自动机模型中,采用MATLAB软件和控制变量的方法,对每个影响因素进行递增取值,得到了每种影响因素的变化对物流企业联盟总数影响的仿真曲线,从曲线中可以看出每种因素对联盟企业总数的影响趋势及变化范围,并通过引入平均变化率指标,找到了各个影响因素对整个系统的影响大小。最后,基于Shapely值,从国际陆港中两个物流企业的角度出发,确定了影响双方利益分配的4个关键性影响因素,即联盟双方投资比重、分摊风险系数、契约的执行力度和对项目的贡献程度。以这4个因素为研究对象,构建了修正Shapely值模型,通过对修正前后分配额度的对比,可以看出修正后的利益分配方案更加贴近于现实场景,更加具有公正性、客观性。该模型考虑的因素更加全面,有效的化解了因利益分配不均而产生的联盟内部矛盾,为国际陆港中评价体系的完善提供了一定的理论依据。本文属于理论研究范畴。主要以物流企业联盟作为理论基础,结合国际陆港的现状及发展趋势,依照事件的发展顺序,分别对国际陆港中物流企业联盟的建立、运行、评价三个方面进行了一系列的建模仿真分析,为国际陆港中物流企业联盟的研究提供了方法和思路,具有一定的指导意义,同时也为国际陆港未来的发展提供了科学合理的理论支撑。
[Abstract]:At present, China's economic development is unbalanced, which is mainly caused by the differences of China's vast regions of the logistics channel. The Midwest lack international convenient logistics channel, increase the logistics cost of intangible, and reduce its export competitiveness, which is the main reason causing the development of the central and western regions and backward restricting the development of its economy. The establishment of the international land port in the central and western regions of great significance, contribute to the development of foreign trade, open and foreign logistics channel, enhance the international competitiveness of the advantages of the product; in addition, from the national level, the establishment of the international land port in the inland areas, the implementation of strategic initiatives to help promote the rise of central China and the development of Western China. The logistics system of the international land port which is a continuous change and development of the system, need multi sectoral participation. Enterprises in the multipole reflect the whole system Plays an indispensable role in the force, plays an important role in the formation and development of the international inland port logistics enterprises, but also to promote all kinds of international land port integrated force formed key force. Within the port logistics enterprise alliance, in favor of mutual complementary resources, collaborative operation. That can make the alliance to form a integrated force, enhance the overall competitiveness of the logistics enterprises alliance in the international inland port. The first, from the definition, characteristics, function and other aspects of the review of the international land port and logistics enterprise alliance, analyzes the development status and future development of the international land port and logistics enterprise alliance trend and necessity of logistics alliance from the perspective of the international inland port is analyzed. Secondly, AHP and genetic algorithm based on the international inland port and understanding of Xiang Guanwen Their reading, determine the factors in the international inland port logistics enterprise alliance partner selection, from the macro level to determine the impact factors of the evaluation index system, through AHP and the combination of genetic algorithm and the fitness function is constructed, using MATLAB simulation software, to search for the alliance logistics enterprises. Thirdly, based on the theory of cellular automaton simulation, complex system composed of logistics enterprises between the international land port, the impact of various factors to the transformation of the cellular automaton model, using MATLAB software and control variables, each of the influencing factors of increasing value, the simulation curve changes of influence factors on the total number of Logistics Enterprises Alliance each kind of influence, the curve can be seen in every kind of influence factors on the total number of enterprises alliance trend and change range, and by introducing the average change rate, Find the size of the impact of various factors impact on the whole system. Finally, based on the Shapely value, starting from the two international inland port logistics enterprise perspective, to determine the impact of 4 important factors affect both the distribution of interests, namely the alliance investment, risk sharing coefficient, contract enforcement and contribution to the project. With these 4 factors as the research object, construct the modified Shapely value model, by comparing the amount of distribution before and after the correction, can see profit distribution scheme revised closer to the real scene, with more impartiality, objectivity. The models considered more comprehensive and effective to resolve internal conflicts and alliances due to the uneven distribution of benefits, provide a theoretical basis for the international inland port in the evaluation system. This paper is the theory research category. Mainly in the logistics enterprise alliance as a theory The foundation, combined with the status quo and development trend of the international land port, in accordance with the sequence of events in development, to establish logistics enterprise alliance, international land port in operation, the three aspects of the evaluation of modeling simulation and analysis of a series of research in the international inland port logistics enterprise alliance provides methods and ideas, has a certain the significance, but also provides theoretical support for the scientific and reasonable international inland port development in the future.
