Purpose The impact of supply disruptions from unplanned events can cause goods shortage, limited responsiveness and high opportunity cost thus compromising development aid programmes' achievement targets. These situations force humanitarian agencies to develop new strategies for effectively managing their supplies. purpose this paper is illustrate the foundation chain resilience through an adap...

    Abstract   Extended Oligopoly models will be introduced and examined in which the firms might face capacity limits, thresholds for minimal and maximal moves, and antitrust thresholds in the case of partial cooperation. Similar situation occurs when there is an additional cost of output adjustment, which is discontinuous at zero due to set-up costs. In these cases the payoff functions of the...

in this paper, a multi-period and multi-resource operating room (or) scheduling and rescheduling problem with elective and semi-elective (semi-urgent) patients is addressed. a scheduling-rescheduling framework based on the so-called rolling horizon approach is proposed to solve the problem. the core of the proposed framework is a novel proposed mixed-integer linear programming (milp) model with...

Given a graph with edge costs, the power of a node is the maximum cost of an edge leaving it, and the power of a graph is the sum of the powers of its nodes. Motivated by applications in wireless networks, we consider several fundamental undirected network design problems under the power minimization criteria. The Minimum-Power Edge-Cover (MPEC) problem is: given a graph G = (V, E) with edge co...

 In this paper, we present a novel eyelash detection model based on three criterions: 1) separable eyelash condition, 2) non-informative condition and 3) connective criterion. The first condition handles separable eyelash and the second condition manages multiple eyelashes. The last criterion avoids misclassification of strong iris texture as a single and separable eyelash. A number of images ...

The autocorrelation function and the run structure are two basic notions for binary sequences, and they have been used as two independent criterions to characterize the randomness of binary sequences for more than 30 years. In this paper, we establish a run series expansion formula for autocorrelation function of the binary sequence and show that the autocorrelation function is in fact complete...

In 1927, Lehmer presented criterions for primality, based on the converse of Fermat’s litte theorem [2]. This work formalizes the second criterion from Lehmer’s paper, a necessary and sufficient condition for primality. As a side product we formalize some properties of Euler’s φ-function, the notion of the order of an element of a group, and the cyclicity of the multiplicative group of a finite...

In this paper, stability analysis of the PDCbased Takagi-Sugeno (T-S) fuzzy impulsive control systems by using the extended Lyapunov stability theory is investigated. Some sufficient conditions and criterions are derived for stability of T-S fuzzy impulsive control system in terms of linear matrix inequalities (LMIs). Finally, control schemes are successfully applied to stabilize a predator-pre...
