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. ...

The paper describes a prototype decision support/expert system for contractor prequalification, CP-DSS. The system firstly evaluates contractors' capabilities according to the project specific criteria. It then identifies any risk that may be caused by contractors. Finally, contractors are appraised according to their likely performance, management capability, reputation, resources, progress, c...

Abandoned coal mine spoils can result in severe pollution and have aesthetic on the local environment. A range of reclamation techniques is available for substrate but only through the use of vegetation to stabilize coal mine spoils can complete long-term rehabilitation be achieved. Experimentation has been undertaken at coal mine sites to attempt to elucidate and overcome limitations to vegeta...

Despite the growing need for decision support in the digital age, there has not been an adequate increase of interest in research and development in Decision Support Systems (DSSs). In our view, the vision for a new type of DSS should provision a tighter integration with the problem domain, and include implementation phase in addition to the traditional intelligence, design, and choice phases. ...

Congestion has plagued air traffic in the US and in Europe for nearly 20 years. To protect air traffic control from overloads, air traffic flow management tries to anticipate and prevent overloads and limit resulting delays. This paper focuses on understanding the requirements for developing re-routing decision support systems (DSS). It identifies participants in re-routing decisions and invest...

This paper deals with the specification of a Decision Support System (DSS) that has to manage the flow of goods and the business transactions between a port and a dry port. The paper investigates the case of the broader area of Trieste port and specifies the DSS that manages the import flows of freights between dry port and seaport. An integrated approach is designed for the tactical level deci...

This paper outlines the features of an automated Decision Support System (DSS) developed to optimize the logistics of maritime transportation for a large chemical company. The paper focuses on the design and implementation of an optimization module to complement a DSS architecture including dynamic databases, decision heuristics, and dynamic process simulation, for the systematic generation of ...

The tobacco distribution in China is organized by the tobacco company in the unit of city. The distribution cycle is commonly a week with five fixed distribution districts started from the center depot, and the routes in each district are fixed for the vehicles and drivers. This method with low efficiency and high cost has continued for several decades because of the poor technology and economi...

Decision support systems (dss) are used for the solution of a wide range of environmental related problems. In order to use dss more efficient it is necessary to divide them according to specific purpose types. Classic dss can be applied to situations in order to investigate the change of a system under certain one-time actions. Because of usual complex initial situations and huge demand of dat...

Agricultural models and decision support systems are becoming increasingly available for a wide audience of users. The Great Plains Framework for Agricultural Resource Management (GPFARM) DSS is a strategic planning tool for farmers, ranchers, and agricultural consultants that incorporates a science simulation model with an economic analysis package and multi-criteria decision aid for evaluatin...
