The aim of this paper is to consider the supplier selection problem under a hierarchical decision system. With consideration of the inherent uncertainty, An decentralized bilevel optimization model under fuzzy random environment is developed for tracking a supplier selection problem with multiple items. For solving the bi-level programming model, an interactive fuzzy programming technique and an improved...
In this paper, we consider a class of linear bi-level programming with random fuzzy coefficients, which has no mathematical meaning because of the uncertain factors. In order to make it solvable, we introduced the linear bi-level model with expected objectives and chance constraints, and propose some theorems to obtain the equivalent models. Then we employ the interactive programming technique to...
In this paper, we introduce a series of perception experiments to measure the just noticeable difference (JND) in black level (BL) and white level (WL) for natural image content under common viewing conditions. Based on these experiments the JND in BL is determined for 13 images and the JND in WL for 18 images. In both cases the JND is found to be image content dependent. To model this image content...
The rapid growth of economy and improvement in living level of households in China require more input of energy, while more energy consumption causes severe environment pollution, which in turn affects environmental quality and economic development. Using grey relevancy analysis and these data about consumption of industrial energy and environmental quality from Henan province, we studied the impact...
MgO thin film is widely used as a protective layer for Alternating Current-type Plasma Display Panels (AC-PDPs) owing to its high anti-sputtering and secondary electron emitting abilities. In order to improve the secondary electron emission coefficient (γ) of MgO thin film, one successful way is to add some dopants into MgO. For example, ZnO, Si and CaO have been used as dopants in the experiments...
Shadow mask plasma display panel (SM-PDP) possesses several interesting features such as simple manufacturing process, low cost, short response time etc. However, its performance on the luminous efficacy, power consumption and production cost is still unsatisfactory Dielectric layers, formed on the front and rear panels, are in series connections with discharge space. The relative permittivity and...
