Simultaneous optimization of time, cost, and utilized resources in a construction project is vital. This paper presents a GA based model for determination of the best combination of the time, cost, and resources in a multiple resource constraint problem. The proposed model considers both resource allocation and leveling simultaneously. Since the problem is assumed to be resource constraint, res...

Resource discovery in a Grid environment is a critical problem and also a fundamental task which provides searching and locating necessary resources for given processes. Based on the domain and resource routing nodes, a grid resource discovery model of multilayer overlay network is given in this paper. And on this basis, using a linear combination of the block distance and chessboard distance i...

Web-based geospatial technology provides the means to enhance the decision making of natural resource managers and the education of natural resource users. This paper discusses the development of a web-enabled application that allows the temporal and spatial representation of raster, vector, and tabular data for natural resource processes and uses through spatially dynamic time series animation...

introduction ownership is an important element for sustainability development in natural resource management. rangelands vegetations are important factor for produce in traditional herding therefore recognition of different utilization methods and management of this vegetation resource production for animal grazing and rangelands condition is very important. so this research carried out in 2009...

The Gene Ontology (GO) project is the largest resource for cataloguing gene function. The combination of solid conceptual underpinnings and a practical set of features have made the GO a widely adopted resource in the research community and an essential resource for data analysis. In this chapter, we provide a concise primer for all users of the GO. We briefl y introduce the structure of the on...

This paper develops an econometric framework to investigate the structure of codependences across markets and to test whether it changes over time or across market conditions. Our approach is based on the computation, over both a test and a benchmark period, of the conditional probability that the returns on one market are lower than a given quantile, when returns on the other market are also l...

A general multi-resource queueing system is defined to be a single congestion point associated with a number of different resource types and having arrivals which require some combination of the system resources simultaneously for the duration of their processing times. Such a system is characterized by a variable processing rate which is a function of the combination of Jobs being concurrently...
