In this paper, an algorithm for extracting information from raw, surveillance-style video of an outdoor scene containing a mix of people, bicycles, and motorized vehicles is presented. A feature extraction algorithm based on background estimation and subtraction followed by spatial clustering and multiobject tracking is used to process sequences of video frames into a track set. The resulting t...

The high complexity of the supply chain network and the characteristics of products made supply chain management of agricultural products were more susceptible to the risks emergence of loss. Therefore, it is required to develop a mechanism for price negotiation which distributes the risks fairly for each stakeholder in the supply chain. In addition it is necessary to identify and evaluate supp...

This paper presents two classes of propositional logics (understood as a consequence relation). First we generalize the well-known class of implicative logics of Rasiowa and introduce the class of weakly implicative logics. This class is broad enough to contain many “usual” logics, yet easily manageable with nice logical properties. Then we introduce its subclass— the class of weakly implicativ...

An integral component of Fuzzy ARTMAP's training phase is the use of Match Tracking (MT), whose functionality is to search for an appropriate category that will correctly classify a presented training pattern in case this particular pattern was originally misclassified. In this paper we explain the MT's role in detail, why it actually works and finally we put its usefulness to the test by compa...

Fuzzy measures are a generalization of probability measures for which additivity is removed and monotonicity is imposed instead. These measures have become a powerful tool in Decision Theory (see e.g. 12, the work of Schmeidler 21 and 3); moreover, the Choquet Expected Utility model generalizes the Expected Utility one, and this model offers a simple theoretical foundation for explaining phenom...

In this paper, we considered decision processes in which one decision is made in each process. We incorporate the utility function concept into the decision process, derived the utility function in fuzzy events and by the max-product operation obtained the utility possibility measure of the fuzzy events. In cases with numerous decision processes, the optimum action can be determined from the re...

Purpose-To determine whether the organisations more strategically committed to its stakeholders present better social and financial performance and, based on this relationship, know the state of the art of the Spanish sectors' approach to the sustainable development. Design/methodology/approach-This paper analyses the sustainability approach of a sample of 52 Spanish listed firms. This process ...

Financial evaluation of listed companies is realized by taking debt paying ability, profitability and operation ability as evaluation standards with the aim of investigating financial situations of companies comprehensively and systematically. The paper puts forward an improved TOPSIS decision-making method. In this method, opinions of more subjective policy makers have been involved: decision ...

In this paper we introduce an approach for solving multiattribute decision-making problems in which there are several decision-makers who individually and independently elicit their preferences. The preferences of each decision-maker are imprecise and represented by an imprecise additive multiattribute utility function. We allow for incomplete information on the component utility functions and ...
