Integrated maintenance and production control of a deteriorating production system
(Kluwer Academic Publishers; Springer Science+Business Media, 2002-05)
We consider a make-to-stock production/inventory system consisting of a single deteriorating machine which produces a single item. We formulate the integrated decisions of maintenance and production using a Markov Decision ...
Feature signature prediction of a boring process using neural network modeling with confidence bounds
(Springer Verlag; Springer-Verlag London Limited, 2005-11-18)
Prediction of machine tool failure has been very important in modern metal cutting operations in order to meet the growing demand for product quality and cost reduction. This paper presents the study of building a neural ...
Control of a manufacturing system with random product yield and downward substitutability
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-09)
We consider a manufacturing system where the quality of the end product is uncertain and is graded into one of several quality levels after production. We assume stochastic demand for each quality level, stochastic production ...
Reducing work-in-process inventory in certain classes of flexible manufacturing systems
(Elsevier, 1986-08)
In this paper, we establish that maintaining a balanced workload on each machine over time stochastically minimizes the work-in-process inventory in certain types of flexible manufacturing systems (FMSs) with finite or ...
Heuristics for minimizing tool switches when scheduling part types on a flexible machine
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-08)
This article considers a tool loading problem whose objective is to minimize the number of tool switches over time in order to process several parts on a flexible machine. New heuristics are presented and compared. Some ...
Integrated design of run-to-run PID controller and SPC monitoring for process disturbance rejection
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-05)
An integrated design methodology has been developed for a run-to-run PID controller and SPC monitoring for the purpose of process disturbance rejection. In the paper, the process disturbance is assumed to be an ARMA (1,1) ...
Interactive computer modules for undergraduate chemical engineering instruction
(John Wiley & Sons, Inc., 1992)
Interactive computer modules have been developed for four of the core courses in the Chemical Engineering curriculum: Introduction to Chemical Engineering, Fluids/Transport, Separations, and Kinetics. These modules generally ...
The GLRT for statistical process control of autocorrelated processes
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-12)
This paper presents an on-line Statistical Process Control (SPC) technique, based on a Generalized Likelihood Ratio Test (GLRT), for detecting and estimating mean shifts in autocorrelated processes that follow a normally ...
Continuous approximation schemes for stochastic programs
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1995-12)
One of the main methods for solving stochastic programs is approximation by discretizing the probability distribution. However, discretization may lose differentiability of expectational functionals. The complexity of ...
Decentralized simultaneous stabilization and reliable control using periodic feedback
(Elsevier, 1992-01)
In this note we consider the simultaneous decentralized stabilization problem for linear, periodically time-varying, discrete time systems. We show that a finite number of periodically time-varying systems can be simultaneously ...
