Modeling and analysis of multi‐stage transfer lines with unreliable machines and finite buffers
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-01)
This paper models and analyzes multi‐stage transfer lines with unreliable machines and finite buffers. The machines have exponential operation, failure, and repair processes. First, a mixed vector–scalar Markov process ...
A Finite Algorithm for Solving Infinite Dimensional Optimization Problems
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-01)
We consider the general optimization problem ( P ) of selecting a continuous function x over a σ-compact Hausdorff space T to a metric space A , from a feasible region X of such functions, so as to minimize a functional c ...
A simple proof of a primal affine scaling method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
In this paper, we present a simpler proof of the result of Tsuchiya and Muramatsu on the convergence of the primal affine scaling method. We show that the primal sequence generated by the method converges to the interior ...
Stochastic scheduling of parallel queues with set-up costs
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1995-12)
We consider the problem of allocating a single server to a system of queues with Poisson arrivals. Each queue represents a class of jobs and possesses a holding cost rate, general service distribution, and a set-up cost. ...
Call Center Staffing with Simulation and Cutting Plane Methods
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-03)
We present an iterative cutting plane method for minimizing staffing costs in a service system subject to satisfying acceptable service level requirements over multiple time periods. We assume that the service level cannot ...
The primal power affine scaling method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
In this paper, we present a variant of the primal affine scaling method, which we call the primal power affine scaling method. This method is defined by choosing a real r >0.5, and is similar to the power barrier variant ...
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 ...
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 ...
Adaptive inventory control models for supply chain management
(Springer-Verlag, 2005-10)
Uncertainties inherent in customer demands make it difficult for supply chains to achieve just-in-time inventory replenishment, resulting in loosing sales opportunities or keeping excessive chain-wide inventories. In this ...
