Search Approach

The evaluation of an organization’s environmental performance is an integral part of a corporate environmental management information system. This chapter considers an organization’s environmental impact assessment with respect to a water resource. It investigates formal approaches to the development of temporal monitoring designs for producing data sufficient to perform the assessment. In this study, simple random sampling, stratified random sampling, and designs obtained using greedy search have been investigated with respect to their compatibility with a corporate environmental management information system. All three approaches determine temporal monitoring designs with minimal costs and supply data sufficient for estimation of water quality indicators for a given level of uncertainty. It is shown that monitoring designs obtained using the greedy search approach will outperform other designs when the level of uncertainty in the estimate must be low. If high levels of uncertainty are tolerable, simple random designs become preferable due to their simplicity and effectiveness. The proposed approaches lead to automated procedures which can be easily integrated into a corporate environmental management information system.

Facing a great deal of materials and data in the process of design and manufacturing of clutch product, Quick and accurate knowledge extraction from the literature resources and web pages is a key to the design of vehicle clutch. The motheds of automatic knowledge acquisition based on literature and XML pages were proposed as well as specific algorithms and processes of knowledge extraction from documents and web pages were constructed.Techniques of knowledge element extraction, agent and ontology were applied to the intelligent type selection system.Practice tells that this intelligent type selection system can better assist intelligent type selection and design of vehicle clutch and knowledge management
