The suppliers selection is a multiple attribute decision making (MADM) problem. Since the decision maker (DM)s like preferences on alternatives or on attributes of suppliers are often uncertain, and thus the selection of good suppliers becomes more difficult. Grey theory is one of the methods that are used to study uncertainty, it is superior in mathematical analysis of systems with uncertain i...

To finding appropriate recycling methods for plastic materials is a critical research issue and the effectiveness of new method being tested in this problem. Decision-making under conditions ambiguity can be difficult due to lack understanding incomplete information. The objective study enhance process selecting most suitable method. address uncertainty group decision-making, essay proposes usi...

In multiperson decision making situations, it is quite natural that different decision makers who may have different background and knowledge will provide their preferences by different kinds of preference relations. This paper proposes a linguistic multiperson decision making model (LMDMM) based on linguistic preference relations, integrating fuzzy preference relations, different types of mult...

The purpose of stock portfolio selection is how to allocate the capital to a large number of stocks in order to bring a most profitable return for investors. In most of past literatures, experts considered the portfolio of selection problem only based on past crisp or quantitative data. However, many qualitative and quantitative factors will influence the stock portfolio selection in real inves...

In this paper we give conditions for a tuple of commutative bounded linear operators which holds in the property of the Hypercyclicity Criterion. We characterize topological transitivity and semi-hereiditarily of a dynamical system given  by an n-tuple of operators acting on a separable infinite dimensional Banach space .

In the literature, Information Technology Infrastructure Library (ITIL) methodology recommends determining priority of incident resolution based on impact and urgency interactions. The RFID model, parameters Recency, Frequency, Importance Duration in incidents, provides an individual assessment a clustering customers these factors. We can improve traditional concept waiting queues for customer ...

In economic development, in addition to comparing the gross domestic product (GDP) between nations, it is critical assess quality of life gain a holistic perspective their different aspects. However, index (QOLI) subjective term that can be difficult quantify. Although this composite typically calculated using universal weights proposed by experts aggregate indicators, such as safety indexes, h...

A typical problem for a parallel processing system involves broadcasting large amounts of data from a master to several worker programs. This paper describes a reliablemulticast method to reduce the communication costs of this distribution. Our solution relies on a tuple-space mechanism as implemented in the Synergy system. We present results showing that even a simple implementation of reliabl...
