In order to protect city from intentional threats, the urban defense engineering has become an important part of urban planning and construction. Based on that, the security planning on urban infrastructure is required to be improved and corresponding security surveillance and early warning systems need to be enhanced. More importantly, the macro-level study of defense resource allocation should be given more considerations. In this study, a resource allocation model focusing on urban defense under the situation with intentional attacking is developed. In this resource allocation model, the rationality level of attackers, the interrelation among targets and other related problems under intentional attacks are all considered. Besides, this model is also validated by using an example, and in this example, the impact of several important parameters have been discussed. It is shown that the expected loss of the optimized resource allocation plan derived from this model is smaller than that of the population proportion-based allocation plan and average-based allocation plan. It also shows that the correlation coefficient of targets has a significant impact of the defense resource allocation. This model can provide the planners and decision makers of urban defense engineering with scientific basis for macroscopic decision making in responding to intentional threats.</p></div>","PeriodicalId":101207,"journal":{"name":"Systems Engineering Procedia","volume":"5 ","pages":"Pages 198-206"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.sepro.2012.04.032","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89441572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
