Lot streaming in open shops
We study lot streaming in shops in which the order the jobs are to be processed is immaterial. For a single job case, the properties of the optimal routing is determined. For the multi job case, two machine shops are ...
On testing independence with right truncated data
Inference with bivariate data gained considerable interest recently, See eg.,,. All of these studies howrver consider estimation of the bivariate distribution function under various bivariate censoring models. ...
Scheduling with neural networks: A review of the literature and new research directtions
(Taylor & Francis, 1998)
Artificial neural networks ( ANNs) attempt to emulate the massively parallel and distributed processing of the human brain. They are being examined for a variety of problems that have been di cult to solve with current ...
A stability concept for zero-one knapsack problems and approximation algorithms
(Taylor & Francis, 1995)
The concept of reducing the feasible range of decision variables or fixing the value of the variables is extended for the knapsack problem to include sets of variables. The ease of fixing these variables is measured by a ...
Residual lifetime distribution and its applications
(Pergamon Press, 1994)
Let T be a continuous positive random variable representing the lifetime of an entity. This entity could be a human being, an animal or a plant, or a component of a mechanical or electrical system. For nonliving objects ...
A characterization of the optimal set of linear programs based on the augmented lagrangian
(Taylor & Francis, 1999)
It is proved that in a certain neighborhood of the optimal set of multipliers, the set of minimizers of the augmented lagrangian nmction generates a new characterization of the optimal solution set of the linear program.
Performance evaluation models for single-item periodic pull production systems
(Palgrave Macmillan, 1996)
A number of pull production systems reported in the literature are found to be equivalent to a tandem- queue so that existing accurate tandem-queue approximation methods can be used to evaluate such systems. In this study, ...
On the Hajek projection for truncated and censored data
(Scientific Publishers, 1993)
Large sample properties of the product-limit estimators for truncated or censored data are usually achieved via the empirical cumulative hazard function estimators. Hajek projection of the empirical cumulative hazard ...
Restoration of space-variant global blurs caused by severe camera movements and coordinate distortions
(IOP Science, 1998)
We show that a broad class of image recovery problems where an object undergoing an arbitrary two-dimensional, time- and space-variant, non-separable, nonlinear global coordinate distortion, is imaged for a certain duration, ...
