Cost-e!ectiveness and computational time are the traditional criteria for evaluating lot-sizing techniques. However, in evolving environments, frequent revisions of demand forecasts may induce various degrees of instability in planned orders, depending on the selected lot-sizing technique. In poorly #exible production systems, the cost of implementing these alterations may overcome the bene"ts ...

Increasing evidence shows that real-world systems interact with one another via dependency connectivities. Failing connectivities are the mechanism behind the breakdown of interacting complex systems, e.g., blackouts caused by the interdependence of power grids and communication networks. Previous research analyzing the robustness of interdependent networks has been limited to undirected networ...

CDMA Timing and phase offsets tracking remain as one of considerable factors that influence the performances of communication systems. Many algorithms are proposed to solve this problem. In general, these solutions process separately the chip sampling offset and phase rotation. In addition, most of proposed solutions can not assure a compromise between robustness criteria and low complexity for...

In this report, the objective is to study how to tune PI controllers in a decentralized control structure for multivariable systems. Robustness with respect to (i) parameter changes, (ii) multivariable interactions including opening and closing other loops and (iii) input saturation are tuning criteria. The SIMC tuning rules are extended to the proposed ‘robust’ SIMC settings which takes expect...

Technology selection is an important part of management of technology. Recently Karsak and Ahiska (2005) proposed a novel common weight multiple criteria decision making (MCDM) methodology for selection of the best Advanced Manufacturing Technology (AMT) candidates based on a number of attributes. However, Amin et al. (2006), by means of a numerical example demonstrated the convergence difficul...

We propose an algorithm-independent framework for rigorously comparing digital watermarking algorithms with respect to bit rate, perceptual quality, computational complexity, and robustness to signal processing. The framework is used to evaluate five audio watermarking algorithms from the literature, revealing that frequency domain techniques perform well under the criteria.

The design of public interfaces follows other criteria as that of mobile or desktop applications. Performative elements enhance the interface and additional requirements of physical robustness are to be taken care of in the design process from the very start. Here, we report on how these two aspects impacted the design of a novel interface called PlazaPuck, created for everyday life on public p...

This paper studies several discriminative models for spoken language understanding (SLU). While all of them fall into the conditional model framework, different optimization criteria lead to conditional random fields, perceptron, minimum classification error and large margin models. The paper discusses the relationship amongst these models and compares them in terms of accuracy, training speed ...
