In flexible manufacturing environments, the performance of a production system is often affected by the sequence of operation. While performance evaluation, improvement and lean design of production system have been studied extensively, the joint effect of productivity and quality parameters on operation sequencing remains practically unexplored. Indeed, determining the optimal operation sequen...

Multiobjective optimal control strategy is pursued here for finding feedback control laws used in controlled suspensions for automotive vehicles. The balanced vehicle ride and handling performances are the main concern of this paper. The ride performance (car body performance) is characterized by an 2 system norm, and the handling performance (wheel performance) is characterized by an system no...

This paper presents a review on techniques for signal reconstruction without phase, i.e. when only the spectrogram (the squared magnitude of the Short Time Fourier Transform) of the signal is known. The now standard Griffin and Lim algorithm will be presented, and compared to more recent blind techniques. Two important issues are raised and discussed: first, the definition of relevant criteria ...

A consumer contest is a sales promotion technique that requires participants to apply certain skills as they compete for prizes or awards. This article is the first to employ a game-theoretical approach to investigate consumer contest design issues, including prize structure, segmentation, and handicapping. First, the authors find that both skill distribution and the number of contestants play ...

An original maintenance decision making tool based on Bruss theorem has previously been investigated by the authors to select the optimal last production stoppage convenient to operate a maintenance action on a component according to its conditions of degradation. This stoppage is optimal with respect to the combination of antagonistic criteria such as maintainability and reliability. The appro...

For a system with a dispatcher and several identical servers in parallel, we propose a policy consisting of modified multi-layered round robin routing followed by shortest remaining processing time scheduling. We show that this policy has a heavy traffic limit that is identical to one in which there is a single queue (no routing) and optimal scheduling. Under light traffic, this policy is asymp...

In this work, optimal control theory is used to derive the optimal production rate in a manu‐ facturing system presenting the following features: the demand rate during a certain period depends on the demand rate of the previous period (dependent demand), the demand rate depends on the inventory level, items in inventory are subject to deterioration, and the firm can adopt a periodic or a conti...

This paper presents a performance metric for the document structure extraction algorithms by finding the correspondences between detected entities and ground truth. We describe a method for determining an algorithm’s optimal tuning parameters. We evaluate a group of document layout analysis algorithms on 1600 images from the UW-III Document Image Database, and the quantitative performance measu...

We review in this article pure quantization methods for the pricing of multiple exercise options. These quantization methods have the common advantage, that they allow a straightforward implementation of the Backward Dynamic Programming Principle for optimal stopping and stochastic control problems. Moreover we present here for the first time a unified discussion of this topic for Voronoi and D...
