【摘要】：随着我国经济的发展和人们消费需求的转变，冷链物流产业迎来了广阔的市场发展前景。由于冷链物流产品容易腐烂变质、保存期限短，因此冷链物流对时效性要求极高，对流通过程中的各个环节之间的协调衔接要求也较高。冷链物流配送中心以及冷链仓储系统作为目前物流领域内的一种新型特殊仓储系统，在冷链物流过程中发挥着十分重要的作用。针对冷链物流及其仓储系统建立其作业流程模型，并进行模型分析和优化，可以帮助管理者发现并解决流程中存在的问题，，提高冷链物流及其仓储系统的运行效率，增加企业竞争力。本文应用多色集合和统一建模语言的复合建模方法，以某企业冷链物流及其仓储系统为研究对象，研究作业流程建模及分析优化问题、模型的组织资源配置问题，并进行冷链物流及其仓储流程的原型系统开发。主要的研究内容和创新点如下：（1）将多色集合和统一建模语言复合建模方法运用到冷链物流及其仓储作业流程建模中。结合某企业冷链物流实际运营情况，利用统一建模语言的基本建模元素和多色集合围道矩阵对冷链配送中心作业流程、成品库出入库作业流程进行建模和分析，提出作业流程优化措施，建立新的冷链物流配送中心及仓储系统出入库流程模型。通过对比优化前后作业流程模型的期望执行时间，验证模型优化的有效性，并完成变更优化后相应的实例迁移。（2）在分析冷链配送中心作业流程组织资源关系的基础上，建立多色集合层次结构模型从活动节点到组织资源的推理过程，为模型中的各个活动进行资源配置，实现冷链物流作业流程模型与组织资源模型的对应。（3）应用Visual C#编程语言和数据库支撑环境，开发冷链物流及其仓储流程过程原型系统，实现复合建模方法理论部分的演示和验证。在对系统基本需求进行分析的基础上，建立原型系统的总体结构，并依次介绍各个模块的主要功能，通过用户界面演示系统作业流程图形化建模、模型映射、结构分析、实例迁移的过程。
[Abstract]:With the development of our country's economy and the change of people's consumption demand, the cold chain logistics industry ushered in a broad market development prospect. Because the cold chain logistics products are easy to rot and deteriorate, the preservation period is short. Therefore, cold chain logistics has a high demand for timeliness. Cold chain logistics distribution center and cold chain storage system is a new type of special storage system in the field of logistics. In the cold chain logistics process plays a very important role. Cold chain logistics and its warehousing system to establish its operational process model, and model analysis and optimization. It can help managers to find and solve the problems existing in the process, improve the efficiency of cold chain logistics and storage system, and increase the competitiveness of enterprises. In this paper, multi-color set and unified modeling language are used to study the modeling and optimization of the operation process, taking the cold chain logistics and its storage system of an enterprise as the research object. The organizational resource allocation problem of the model, and the prototype system development of cold chain logistics and its warehousing process. The main research contents and innovations are as follows: 1) applying the method of polychromatic set and unified modeling language to the modeling of cold chain logistics and its warehousing process, combined with the actual operation of a certain enterprise cold chain logistics. Using the basic modeling elements of the unified modeling language and the polychromatic set path matrix, the operation flow of the cold chain distribution center and the product storehouse were modeled and analyzed, and the optimization measures of the job flow were put forward. Establish a new cold-chain logistics distribution center and warehousing system out and out process model. By comparing the expected execution time before and after optimization, verify the effectiveness of model optimization. The corresponding instance migration is completed after the change optimization. 2) on the basis of analyzing the relationship of organizational resources in the operation process of cold chain distribution center, a multi-color set hierarchy model is established for the reasoning process from active node to organizational resource. The resource allocation is carried out for each activity in the model to realize the correspondence between the cold-chain logistics process model and the organizational resource model. The prototype system of cold chain logistics and storage process is developed by using Visual C # programming language and database supporting environment. Based on the analysis of the basic requirements of the system, the overall structure of the prototype system is established, and the main functions of each module are introduced in turn. The process of graphical modeling, model mapping, structure analysis and instance migration is demonstrated by user interface.
