Aviation project which always involves too many resources need to do resource leveling for enhancing the utilization of resources so as to reducing project cost. Intelligent optimization algorithms and heuristic approaches are inefficient and inflexible when solving large-scale aviation resource leveling problems. A hybrid algorithm based on Artificial Immune Algorithm (AIA) and Ant Colony Optimization...
Element method model construction, a new approach for product modeling, is to positively impact on the front-end modeling methods for product design through boundary-lines of design deriving from progressive constraints on different parameter conditions.
In this paper we analyze whether the two tasks of building and operating infrastructures used for the provision of public services should be bundled or not, by studying the investment incentives which are the core of the bundling issue. We present a basic model in a multitask environment considering both productive efforts and unproductive efforts in quality improvement and cost reduction. We then...
This paper presents some methods for constructing new resilient functions from old ones. These methods are significant generalizations of some previously known methods. Furthermore, we construct some infinite families of resilient functions with optimal nonlinearity which is particularly well-suited for combining linear feedback shift registers.
Land use/cover change is an important issue for global environmental research. Combined with the use of GIS, this paper explores the utilities of CBERS images to analyze the land use/cover changes in the city of Lianyungang, and analyzes the driving forces by the principal component analysis. Results show that during the past 8 years, the local land use pattern has changed greatly, especially for...
