Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. In these environments, the required resources must be accessible for Grid applications on demand, which makes the resource discovery as a critical service. In recent years, various techniques are proposed to index and discover the Grid resource...

In this paper, a due date assignment scheduling problem with precedence constraints and controllable processing times in uncertain environment is investigated, in which the basic processing time of each job is assumed to be the symmetric trapezoidal fuzzy number, and the linear resource consumption function is used.The objective is to minimize the crisp possibilistic mean (or expected) value of...

Human resource management has increasingly become one of the most important challenging issues in the pharmaceutical industry in general and in developing countries in particular to increase the access of societies to needed medicines. In this study, an attempt was made to explore the challenges of human resource management practices surrounding pharmaceutical firms in Iran, as a developing cou...

introduction conventional operations in fields, soil and water management are not efficient and loss of and damage to the environment are considerable (lal, 2000). crop diversity and understanding the complex interactions between environmental and socioeconomic factors are approaches to make better use of limited resources (tengberg et al., 1998). the most diverse ecosystems have a higher produ...

Abstract Recent advances in quantum resource theories have been driven by the fact that many information protocols make use of different facets same physical features, e.g. entanglement, coherence, etc. Resource formalise role these important features a given protocol. One question remains open until now is: how quickly can be generated or degraded? Using toolkit speed limits we construct bound...
