recently, lotfi et al. [10] established an equivalence model between the output-oriented dual ccr model and multiple objective linear programming (molp) and used an interactive method for finding target unit on efficiency frontier such that the decision maker preferences can be taken into account. however their method is not applicable for situations in which some outputs are undesirable and ne...

Peskun ordering is a partial ordering defined on the space of transition matrices of discrete time Markov chains. If the Markov chains are reversible with respect to a common stationary distribution π, Peskun ordering implies an ordering on the asymptotic variances of the resulting Markov chain Monte Carlo estimators of integrals with respect to π. Peskun ordering is also relevant in the framew...

Lead time is one of the major limits that affect planning at every stage of the supply chain system. In this paper, we study a continuous review inventory model. This paper investigates the ordering cost reductions are dependent on lead time. This study addressed two-echelon supply chain problem consisting of a single vendor and a single buyer. The main contribution of this study is that the in...

 In this paper, we study stochastic comparisons of order statistics of independent random variables with proportional hazard rates, using the notion of variance majorization.

A new path ordering for showing termination of associative-commutative (AC) rewrite systems is deened. If the precedence relation on function symbols is total, the ordering is total on ground terms, but unlike the ordering proposed by Rubio and Nieuwenhuis, this ordering can orient the distributivity property in the proper direction. The ordering is deened in a natural way using recursive path ...

inventory models play an important role in determining the optimal ordering and pricing policies. much work has been reported in literature regarding inventory models with finite or infinite replenishment. but in many practical situations the replenishment is governed by random factors like procurement, transportation, environmental condition, availability of raw material etc., hence, it is nee...

A salient feature of cooperative work in modern work settings is that multiple actors so to speak interact ‘through’ a large collection of artifacts of various kinds. An actor may for example place a document in a location where others can see it and use it. The actor may place it there for his or her own later use, but at the same time others may access it too, or the actor may place it there ...

It has often been assumed that ordering problems form a special class of problems amenable to a largely uniform treatment. Since successful ordering Genetic Algorithms (gas) have been deened for optimization of some ordering problems, it has become customary to assume that ordering problems are well solved by ordering gas tted with standardd operators. The success of the standard ordering gas o...
