A combinatorial approach to a class of parallel-machine, continuous-time scheduling problems.
March 1, 2002... ********** Konstantin Kogan (1) Eugene Khmelnitsky (2) Eugene Levner (1) The paper analyzes a manufacturing system with N non-identical, parallel machines continuously producing one product type in response to its demand....

Optimal leadtimes planning in serial production systems with earliness and tardiness costs.(Statistical Data Included)
March 1, 2002... ********** We consider a production system consisting of N processing stages. The actual leadtimes at the stages are stochastic. The objective is to determine the planned leadtimes at each stage so as to minimize the expected total...

Learning in tele-operations.(Statistical Data Included)
March 1, 2002... ********** Joseph Bukchin (1)(*) Ruth Luquer (1) Avraham Shtub(2)(+) Tele-operation is used when a task has to be performed in a hostile, unsafe, inaccessible or remote environment. Examples of teleoperation include the...

Dynamic release policies for software systems with a reliability constraint.(Statistical Data Included)
March 1, 2002... ********** We discuss the optimal release problem of computer software. A conditional non-homogeneous Poisson process model is used to describe the software reliability growth behavior. By formulating with Markov decision programming, we...

Analysis of wafer fabrication facilities using tour variations of the open queueing network decomposition model.(Statistical Data Included)
March 1, 2002... ********** John Miltenburg (1)(*) Chun Hung Cheng (2) Houmin Yan (2) We analyze three wafer fabrication facilities with four open queueing network decomposition models -- Whitt (1983, 1985), and Bitran and Tirupati (1988),...

Neural network prediction in a system for optimizing simulations.(Statistical Data Included)
March 1, 2002... ********** Manuel Laguna (1) Rafael Marti (2) Neural networks have been widely used for both prediction and classification. Back-propagation is commonly used for training neural networks, although the limitations associated with...

A best-first search approach for determining starting regions in simulation optimization.(Statistical Data Included)
March 1, 2002... ********** Loren Paul Rees (1) Alldn G. Greenwood (2)(*) Fernando C. Siochi (3) Many simulation optimization approaches assume that a "good" starting point is identified, that the design grid (i.e., spacing of runs for...

An investigation of the relationship between problem characteristics and algorithm performance: a case study of the GAP.(Statistical Data Included)
March 1, 2002... ********** Marne C. Cario (1) John J. Clifford Raymond R. Hill (3))(*) Jaehwan yang (4) Kejian Yang (5) Charles H. Reilly (6) We compare synthetic Generalized Assignment Problems (GAP) generated under two...

Neural networks to model dynamic systems with time delays.(Statistical Data Included)
March 1, 2002... ********** Nazario D. Ramirez-Beltran (*) An algorithm is proposed to identify a neural network model that represents a nonlinear dynamic system with a multivariate time delay response. The algorithm consists of two major parts. The...

Fundamentals of Systems Engineering. (Book Reviews).
March 1, 2002... C. Jotin Khisty Jamshid Mohammadi Prentice-Hall, 2001, 475 pages, ISBN 0-13-010649-6 Some systems engineering textbooks for undergraduate students are so specific that their niche in the engineering profession is not so clear....

Intelligent Optimization Techniques. (Book Reviews).
March 1, 2002... D.T. Pham and D. Karaboga Springer Verlag, London 2000, 302 pages, ISBN 1-85233-028-7 This book explores four well-known meta-heuristic approaches for solving complex optimization problems that arise in engineering and industry....

Arc Routing: Theory, Solutions and Applications. (Book Reviews).
March 1, 2002... Moshe Dror (editor) Kluwer Academic Publishers, 2000, ISBN 0-792-37898-9 In 1736, in a communication presented at the St. Petersburgh Academy, Leonhard Euler, probably the most emblematic mathematician of the 18th century, presented...

Simplicial Algorithms for Minimizing Polyhedral Functions. (Book Reviews).
March 1, 2002... M.R. Osborne Cambridge University Press, 2001, 247 pages, ISBN 0-521-79133-2 This book explores geometric concepts to optimize polyhedral functions via simplicial algorithms that approach an optimum via a vertex to vertex descending...
