Abstract


With the development of simulation tools become more powerful, modeling work is not as boring and greatly reduce the difficulty of modeling , modeling workload is reduced a lot , it really brings to the modeling work convenient. But the modeling work in any course there are a lot of repetitive work , and when the mock object becomes complex , design and coding will greatly increase the workload of the modeling work has become very hard. Through the CBR technology, created with the needs of a similar model for reuse and re-development , modeling can effectively reduce repetitive work and improve the modeling efficiency. This thesis mainly around the Arena discrete model reusability conduct research , its main research work is as follows : in -depth study of Arena software and CBR methods and key technologies based on the combination Arena discrete model the characteristics of the Arena model parameterization, then identify the most suitable examples Arena model representation of the Arena model cases be represented . Arena models built using Microsoft Access database , using the data table relationships within the model to reflect the Arena association between attributes . Designed a three query strategy, test case library , and examples of case library for a preliminary screening to generate a smaller set of models , to improve the efficiency of similarity calculation . Arena models for a variety of attributes and attribute values ​​type, using the nearest neighbor algorithm for attribute similarity calculation ; Arena model modules based on the connection between property , the model is abstracted into a directed graph , similar to using a directed graph degree algorithm Arena model topology similarity calculation ; comprehensive two algorithms to derive the overall similarity Arena model calculation algorithm . And select the particle swarm algorithm (PSO) to achieve, finally tested the effectiveness of the algorithm .
