We propose a new method for evaluating the benefits of decision-oriented information systems. This method is based on a detailed analysis of decision processes. Using prescriptive decision theory, correct results are established for different sub-phases of the process and possible deviations from these results are analyzed. Systems are then evaluated according to their contribution to the elimi...

New class of methods is needed to support decision makers in complex and dynamically changing environments. Agent-based simulation combined with human-oriented machine learning provides robustness and efficiency, and at the same time ability to explain reasons for selected plans to decision makers. This makes the method ideal for decision support in healthcare, medicine, security, disaster plan...

Decision tree construction is an important data-mining problem. In this paper we introduce an approach of using cumulative information estimations for fuzzy decision tree induction. We present new type of fuzzy decision tree: ordered tree. This tree is oriented to parallel processing of attributes with differing costs.

Data warehouse is subject Oriented, included, TimeVariant and nonvolatile collection of data. This data helps in supporting decision making process by analyst in an organization. The Business intelligence is the delivery of accurate, useful information to the appropriate decision makers with necessary timeframe to support effective decision-making. This paper reviews the impact of metadata in d...

(2010) Value-oriented process modeling : integrating financial perspectives into business process redesign. Abstract Purpose – Financial information about costs and return on investments are of key importance to strategic decision-making but also in the context of process improvement or business engineering. In this paper we propose a value-oriented approach to business process modeling based o...

Requirements for database systems differ from small-scale stripped minimal database programs for embedded devices with minimal footprint to large-scale on-line analytical processing applications. For relational database management systems, two storage architectures have been introduced: a) row-oriented architecture and b) column-oriented architecture. In this paper, we present a query decomposi...

Decision making for crop production planning is essentially driven by location-based or more precisely by space-oriented information. Therefore, farmers and regional experts in the field mostly rely on new spatial-data-oriented decision making tools. IVIP is a prototype for a Web-based Spatial Decision Support System (WSDSS) demonstrating the benefits of location-based decision making using dig...

The promise of online assemblies has been present for years already, and a diversity of tools have attempted to fulfill it. This work aims to reapproach the issue from a novel standpoint that relies on a federated architecture, a real-time collaborative environment, goal-oriented software agents and a consensus-based methodology. Consensuall is a prototype of consensual decision-making collabor...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...
