this paper submitting the computation of optimize point of ordering in inventory control systems and particularly for continuous review of ordering system (r,q) by fuzzy logic method which similarly can be used for other ordering systems. since in the ordering models we cannot forecast the parameters like cost exactly, we have ambiguity. in this case using precise parameters may cause wrong dec...

We introduce an optimality theory for finite impulse response (FIR) filterbanks using a general algebraic point of view. We consider an admissible set of FIR filterbanks and use scalability as the main notion based on which performance of the elements in are compared. We show that quantification of scalability leads naturally to a partial ordering on the set . An optimal solution is, therefore,...

Disc jockeys are in some ways the ultimate experts at selecting and playing recorded music for an audience, especially in the context of dance music. In this work, we empirically investigate factors affecting track selection and ordering using mixes created for the Essential Mix. The Essential Mix is a well known weekly radio show on BBC Radio 1 that showcases various styles of electronic dance...

Interference alignment (IA) has recently emerged as a promising interference mitigation technique for interference networks. In this letter, we focus on the IA non-iterative transceiver design problem in a multiple-input-multiple-output interfering broadcast channel (MIMO-IBC), and observed that there is previously unexploited flexibility in different permutations of user ordering. By choosing ...

In this paper, we consider the problem of nding llpreserving ordering of a sparse symmetric and positive de nite matrix such that the reordered matrix is suitable for parallel factorization. We extended the unitcost ll-preserving ordering into a generalized class that can adopt various aspects in parallel factorization, such as computation, communication and algorithmic diversity. Based on the ...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...

Ordering clones from a genomic library into physical maps of whole chromosomes presents a central computational problem in genetics. Chromosome reconstruction via clone ordering is shown to be isomorphic to the NP-complete Optimal Linear Ordering problem. Massively parallel algorithms for simulated annealing based on Markov chain distribution are proposed and applied to this problem. Perturbati...

We consider an economic lot-sizing problem with a special class of piecewise linear ordering costs, which we refer to as the class of modified all-unit discount cost functions. Such an ordering cost function represents transportation costs charged by many less-thantruckload carriers. We show that even special cases of the lot-sizing problem are NP-hard and therefore analyze the effectiveness of...

Variable ordering heuristics are used to reduce the cost of searching for a solution to a constraint satisfaction problem. On real problems that have non-binary and non-uniform constraints it is harder to make the optimal choice of variable ordering because surprisingly little is known about when and why variable ordering heuristics perform well. In an attempt to address this problem we present...
