This paper identifies the need for a formalized approach to the assessment of the integrity of stone masonry bridges and develops the concept of the use of a computer database and suitable software to support the practising bridge engineer in the decision-making process (decision support software, DSS).

The different standard techniques of assessment of masonry bridges are outlined and their limitations described. The common faults associated with masonry structures are discussed and the problems of identifying these faults are described. The part played by the individual components of a masonry arch bridge is outlined and the significance of faults on the individual components of the structure is discussed.

Database development and operation of the DSS are detailed and their value to the bridge engineer is discussed. The system is illustrated with a demonstration run.  相似文献

A decision support system (DSS) was developed on a personal computer for the economic design of steel structures. The DSS contains six various-type single-criterion and seven multicriteria optimization methods. The economic design of the asymmetric main box girders of overhead travelling cranes was realized by considering four objective functions and sixteen nonlinear inequality constraints according to BS 2573 and BS 5400. Constraints on static and fatigue stress, on local buckling of flange and web plates, as well as on static deflection, are considered. Numerical computations show the effects of material, welding, surface preparation and total cost on each other. Use of higher strength steel may result in savings on the cost of materials, depending on the cost factor employed.  相似文献

Recent disasters have shown that road tunnels are especially complex environments for decision making. A fast and effective response to emergencies in road tunnels is a key factor for life safety. This paper presents a decision support system (DSS) for emergency management in road tunnels. Based on a specific methodology, the system provides the operator with decision recommendations to deal with the emergency in real time. Furthermore, the system uses predictive tools to estimate the severity of the accident or incident, as well as rescue and evacuation times. This information is very useful during the first stages of an emergency when information is scarce, incomplete and inaccurate, yet the tunnel operator is required to make the right decisions under a high level of stress. The DSS reduces the decision circle and allows the operator to make critical decisions based on dynamic alternatives. The system has been tested in various hypothetical emergency cases based on the Tunnel of Lantueno in the A-67 Highway, Spain. The application cases show that the DSS provides reasonable and consistent results.  相似文献

A decision support system (DSS) devoted to water–quality planning is described. The DSS is based on a graphic multiple–criteria technique called generalized reachable sets (GRS) method, which provides experts and decision makers with objective tradeoff curves among cost and pollution criteria. The information improves their understanding of the problem and helps to identify wastewater treatment strategies that provide reasonable balance between cost and pollution. These strategies are starting points for further negotiation between governmental agencies, private and state–owned enterprises, and regional and local authorities involved in wastewater treatment. The DSS is implemented on personal computers.  相似文献

A decision support system (DSS) is introduced for evaluating and comparing a wide range of privatisation schemes for infrastructure facilities. The methodology identifies the preferences of the main stakeholders involved, along with all the environmental, political, technical and economic criteria that need to be considered in privatisation decisions. A DSS is then developed and tested on a case study involving the privatisation of a wastewater project. The system provides decision support through three steps: (1) screening of infeasible decisions using the elimination method of multiple criteria decision analysis; (2) determining the most stable decision by analysing the actions and counteractions of the stakeholders using conflict resolution and stability analysis; and (3) evaluating the robustness of decisions under varying levels of uncertainty using information gap theory. The DSS is useful for practitioners involved in infrastructure privatisation decisions for a variety of infrastructure systems such as transportation, water and energy.  相似文献

How to provide construction managers with information about and insight into the existing data, so as to make decision more efficiently without interrupting the daily work of an On-Line Transaction Processing (OLTP) system is a problem during the construction management process. To solve this problem, the integration of a data warehouse and a Decision Support System (DSS) seems to be efficient. ‘Data warehouse’ technology is a new database discipline, which has not yet been applied to construction management. Hence, it is worthwhile to experiment in this particular field in order to gauge the full scope of its capability. First reviewed in this paper are the concepts of the data warehouse, On-Line Analysis Processing (OLAP) and DSS. The method of creating a data warehouse is then shown, changing the data in the data warehouse into a multidimensional data cube and integrating the data warehouse with a DSS. Finally, an application example is given to illustrate the use of the Construction Management Decision Support System (CMDSS) developed in this study. Integration of a data warehouse and a DSS enable the right data to be tracked down and provide the required information in a direct, rapid and meaningful way. Construction managers can view data from various perspectives with significantly reduced query time, thus making decisions faster and more comprehensive. The applications of a data warehousing integrated with a DSS in construction management practice are seen to have considerable potential.  相似文献
