Research On The Established Method Of Case Representation Module In Case Based Reasoning System Of Line Engineering

China's long-term large-scale transport infrastructure construction,built a large number of different conditions of the project,and in a variety of complex and volatile conditions to carry out the design work has accumulated a wealth of experience.At present,many research results through the mining line project case data,summed up the design experience,the interdisciplinary thinking into the line design,to explore a number of new design and new lines location design.In view of the need of line design development,this paper introduces case-based reasoning(CBR)into line design work,and explores the case expression with line characteristics.The main purpose of the study is to provide new theories and methods for the design of inherited empirical lines,to solve the problem of expressive feedback of line design defects exposed to the operation of line cases,to adapt to the rise of cloud computing and large data for digital design,intelligent and multi-line Interdisciplinary change requirements.In order to achieve the above goal,this paper studies the characteristics of different cases of line cases,analyzes the characteristics of different cases,constructs the case element set,establishes the case representation module and builds the theory and implementation method.In-depth exploration and research,the main research content and results are as follows:(1)to study the main theory of case-based reasoning,to explore its feasibility of the application of line design,combined with the basic principles of case-based reasoning and method,the advantages and disadvantages of case-based reasoning system analysis.(2)the case under different environmental conditions as a follow-up project reference objectives,from a wide range of multi-angle comprehensive display case features.The feature attribute of the line case is classified according to the factor,and the feature set is established according to the principle of knowledge expression.(3)the main focus of the main types of data types,to explore the case library system to build the main technology and implementation.Using the relationship database technology and the related technology of geographic information system,the combination of line case and case reasoning method is completed,and the establishment of case representation module is completed,and the case input and display are realized.The study of the method of establishing case study module can provide effective case reference for design work,effectively solve the problem of design defect design expression in operation,and meet the requirements of data mining and interdisciplinary interdisciplinary,which enriches the optimization method of line design,Line project case-based reasoning system,and even promote the case reasoning in the extensive use of line design has a certain role in promoting.
