Abstract—Advances in computing applications in recent years have prompted the demand for more flexible scheduling models for QoS demand. Moreover, in practical applications, partly violated temporal constraints can be tolerated if the violation meets certain distribution. So we need extend the traditional Liu and Lanland model to adapt to these circumstances. There are two extensions, which are...

a r t i c l e i n f o The literature on short-selling restrictions focusses mainly on a ban's impact on market efficiency, liquidity and overpricing. Surprisingly, little is known about the effects of short-sale constraints on herd behaviour. Since institutional investors have come to dominate mature stock markets and rely extensively on short sales, constraining these traders may influence the...

In this paper, we are interested in non parametric density estimation under constraints. It generalises a previous paper which was devoted to density estimation with non-positive kernels. The resulting density approximation improves the estimation (by reducing the bias) but provides negative values. Therefore, we have proposed a projection method on the space of probability densities and an alg...

The basic aim of this paper is to an application of triangular intuitionistic fuzzy numbers(TIFNs) to a single non-cooperative bi-matrix games. Firstly, the concept of TIFNs and their cut sets are introduced as well as the inequality relations between two TIFNs. Secondly, a bi-matrix game with payoffs of TIFNs is considered and an attempt is made to conceptualize the meaning of a Nash-equilibri...

This paper describes a set of experiments performed with an artiicial futures market simulation. The non-rational market participants, which evolve simple strategies using genetic algorithms, compete against each other to make proots by buying and selling futures contracts. The dynamic and equilibrium behavior of the participants is studied under a variety of conditions. The results suggest tha...

This paper introduces a general, set-theoretic model for expressing dynamic integrity constraints, i.e., integrity constraints on the state changes that are allowed in a given state space. In a managerial context, such dynamic integrity constraints can be seen as representations of ``real world'' constraints and business rules. This topic has important practical applications in many business ar...

Use of constraint-based techniques in interactive graphics applications poses a variety of unique challenges to system implementors. This paper begins by describing how interface concerns create demands on interactive, constraint-based, graphical applications. We will discuss why such applications must be able to handle systems of non-linear constraints, and survey some of the techniques availa...

Housing markets experience substantial price volatility, short term price change momentum and mean reversion of prices over the long run. Together these features, particularly at their most extreme, produce the classic shape of an asset bubble. In this paper, we review the stylized facts of housing bubbles and discuss theories that can potentially explain events like the boom-bust cycles of the...

This paper presents a mathematical model of inventory control problem for determining the minimum total cost of multi-item multi-objective inventory model with fuzzy estimated price dependent demand, fuzzy deterioration and possible constraints. Here, three constraints we have taken; they are warehouse space constraint, investment amount constraint and the third constraint is the percentage of ...

We consider a model in which any investment opportunity is described in terms of cash flows. We don’t assume that there is a numéraire, enabling investors to transfer wealth through time; the time horizon is not supposed to be finite and the investment opportunities are not specifically related to the buying and selling of securities on a financial market. In this quite general framework, we sh...
