Research And Development Of SOA-Based Logistics Route Optimization System

As one of the important industries for China's economic development,the logistics industry has been developing very rapidly in recent years.In the traditional logistics distribution business,route planning is performed manually in a high degree.Inefficient operations can not adapt to the rapid growth of enterprise business.According to the actual demand for transportation,automatic route planning is a key problem to improve the logistics efficiency and service quality.Therefore,research and development of a logistics management business system that supports automatic route planning has become one of the urgent needs of logistics companies.Aiming at solving the above problem,the thesis develops a logistics route optimization system based on the service-oriented architecture(SOA).Firstly,the system development requirements are analyzed including functional and non-functional requirements.Against the issue involved in logistics companies' distribution routes in the same city,we defines the distribution conditions,constraints,and distribution goals.In terms of information management,the factors such as staff,drivers,management personnel,and vehicles are considered,and the business model and process are pointed out.Secondly,the algorithms and applications related with route optimization are studied.On the one hand,the logistics issues are discussed in depth,mainly covering regional division and vehicle routing problems,and the common algorithms for solving these problems are analyzed and compared.On the other hand,the key technologies used in system development are introduced,including the Web Development Framework,Baidu Map API,and Android Application Development.Thirdly,the system design scheme is proposed.Based on the overall architecture design,the system is divided into three parts: route optimization algorithm module,business function module and database design.The algorithm module mainly covers the analysis of actual problems,the establishment of mathematical models,and the selection and evaluation of algorithms.The business function module mainly includes system management,data management and business management.The database design is given and shown in the form of E-R charts and database tables.Finally,the system development is completed based on the JAVA Web SSM framework.The route optimization algorithm provides external services in the form of Web service interfaces,loosely coupled with the rest of the system.This thesis fulfills the concurrent execution of optimization tasks in a multi-threaded mode.The logistics route optimization system supports the management of company employees and role/rights,the management of sales point,vehicle and driver,and the planning and adjustment of routes.In addition,we make full use of the Baidu Map API to visualize distribution routes on Web maps.The mobile application has functions such as point-of-sale inquiries and route inquiries,which make it easier for drivers to complete delivery tasks.The final system is tested,and the test results show that the developed system has achieved the expected goal,and will promote the distribution business of logistics enterprises.
