Security investment problems are mostly highly-nonlinear and have huge operations, hence quantitative investment is applied to make decisions frequently. Considering the example of Medicine plate in Chinese stocks, fundamental indicators and technical indicators are combined, and then investment decisions are made and optimized stepwise based on rough set model, where generical gorithm is appli...

While enterprise collaboration has become a significant factor to achieve business success, the distributed structure of virtual enterprise environments still carries new challenges towards successful operation of business processes within these networks. As one group of business process, innovation processes do challenge virtual enterprises to a much higher degree, because new products and ser...

Further researching and development in the field of health and safety at work should be looking beyond traditional principles, on a quite new, innovative and contemporary approach. Changing the approach is natural, obvious and necessary regarding frequent technology improvement on all fields, emerging industrial facilities, big social, economical and demographic changes, as well as changes of w...

This paper synthesizes available information on five Category A pathogens (Bacillus anthracis, Yersinia pestis, Francisella tularensis, Variola major and Lassa) to develop quantitative guidelines for how environmental pathogen concentrations may be related to human health risk in an indoor environment. An integrated model of environmental transport and human health exposure to biological pathog...

The environment has emerged as an important determinant of the performance of the modern chemical industry. Process engineering in the 21 century needs to evolve to include environmental issues as part of the design objectives, rather than as constraints on operations. A frequently cited objection to the use of quantitative indicators of environmental performance in product and process design i...

This paper presents an approach for the integrated consideration of both technical and valuation uncertainties during decision making supported by LCA-type environmental performance information. Key elements of this approach include “distinguishability analysis” to determine whether the uncertainty in the performance information is likely to make it impossible to distinguish between the activit...

In this work, we propose extending the production planning decisions of a chemical process network to include optimal contract selection under uncertainty with suppliers and product selling price optimization. We use three quantity-based contract models: discount after a certain purchased amount, bulk discount, and fixed duration contracts. We propose the use of general regression models to des...

E xcess weight, particularly central obesity, is recognized to be a major determinant of diabetes risk in all populations, with the magnitude of the association reported as being stronger in Asians than whites (1–3). Consequently, indicators of overweight have been incorporated into several guidelines for the early identification of individuals with type 2 diabetes (4). However, the anthropomet...

Due to the deflection of light by density fluctuations along the line of sight, weak lensing is an unavoidable systematic uncertainty in the use of type Ia supernovae (SNe Ia) as cosmological distance indicators. We derive the expected weak lensing signatures of SNe Ia by convolving the intrinsic distribution in SN Ia peak luminosity with magnification distributions of point sources. We find th...

Mainstreaming adaptation in infrastructure development is a crucial component of building resilience to climate change impacts. This Insight presents an appraisal of economic projects to support the assessment of adaptation options to river and coastal flooding in the city of Bilbao in Spain. The economic methodology to incorporate uncertainty into decision-making processes considers three appr...
