This study incorporates risk assessment and risk management methodologies in the analysis of four separate case studies involving VDOT assets. The results of this study provide insight not only as to how to manage the cascading effects of interdependent infrastructures within the individual case studies, but are applicable to the state of Virginia, as a whole.

The modern fixed satellite service provider seeks improved methods to optimize the amount of service demand that is accommodated by capacity available on its satellite network. A mixed-integer programming (MIP) model is proposed for the solution of the problem, as part of a decision support tool. Such a tool integrates three system components, which are: a mathematical optimization model, an optimization algorithm, and a graphical user interface.

The U-line arranges machines around a U-shaped line in the order in which production operations are performed. Operators work inside the U-line. We address the Type 1 U-LBP using heuristic rules adapted from the simple LBP. Then these heuristic approaches are compared with the optimal solutions obtained from the previous published research work. Finally the heuristic rules are used as genes to find optimal or near optimal solutions using a genetic algorithm adapted from the simple LBP genetic algorithm proposed by Ponnam-balam, Aravindan, and Mogilesswar (2000). The results showed that some very simple heuristic rules produced optimal or near optimal solutions.

These weekly-structured documents have no rigid structures, and often called semistructured data. Hence, there have been increasing demands for efficient methods for discovering patterns in large collection of semistructured data. We study a data mining problem of discovering frequent subtrees in a large collection of XML data, where both of the patterns and the data are modeled by labeled ordered trees. We present an efficient algorithm RSTMiner that computes all rooted subtrees appearing in a collection of XML trees with frequent above a user-specified threshold using a special structure Me-tree. In this algorithm, Me-tree is used as a merging tree to supply scheme information for efficient pruning and mining frequent subtrees. The keys of the algorithm are efficient pruning candidates with Me-Tree structure and incrementally enumerating all rooted subtrees in canonical form based on a extended right most expansion technique","PeriodicalId":287496,"journal":{"name":"Proceedings of the 2004 IEEE Systems and Information Engineering Design Symposium, 2004.","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130807085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a survey method that combines logistic regression and usage statistics to examine technology adoption. This method was used to evaluate the effect of preference and usability factors on crime analysts' adoption of a Web portal for information sharing. The initial decision to adopt was assessed by survey results, usage statistics and user feedback. The portal did not succeed because of the following reasons: lack of time to use it; having only recently gained access to it; low Internet usage; and poor usability.

This new version, called the Tactical Tomahawk Missile, requires en route monitoring, control, and oversight by human operators. Previous research led to the design, implementation, and testing of a graphical multiuser interface system for human supervisory control of a missile \"strike\" (multiple missile fired together to various targets). The purpose of this study was to test the merits of a decision matrix as a high-level decision making aid, to validate previous findings about how missile load affects performance. Forty-two University of Virginia students participated as subjects. Missile level varied between 8, 12, and 16 missile, and interface type varied between having the decision matrix or not. The results confirmed that the decision matrix is a useful tool, but they failed to verify previous missile loading estimates","PeriodicalId":287496,"journal":{"name":"Proceedings of the 2004 IEEE Systems and Information Engineering Design Symposium, 2004.","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117160595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This initiative will clear approximately 500,000 square feet on the Manufacturing Center campus that was previously allocated for direct materials storage. The focus of this project is to determine the most efficient and effective way to allocate the newly available space. Two strategies were developed to determine the optimal layout for the Manufacturing Center. First, a manual heuristic, strategic layout planning, uses department adjacency requirements to determine the order to place departments into the layout, creating multiple layouts. Second, a mathematical optimization program using CPLEX and AMPL determines the optimal layouts that minimize material flow costs and maximize department adjacencies. Each developed layout is evaluated on both meeting desired department adjacencies and minimizing the material flow cost per week.
