This paper considers a supplementary supply-order system in a multi-period situation. In each period, the buyer first places an initial order based on the demand prediction; he has the opportunity to place a supplementary order with the supplier after the demand of that period is realized. The...

This study analyzes the impacts of climate change on maize yields using an econometric model that incorporates climate, economic, and technology variables. The major finding is climate change will not universally cause negative impacts of maize yields in the United States and China. The results...

This study replicates and augments a segmentation approach with overlapped schemes by examining the Chinese outbound travel market. A total of 1600 past and potential long-haul Chinese outbound tourists in three Chinese cities were surveyed and segmented into three groups with overlapped segment...

In this paper, we propose a novel Euclidean distance preferred model yielding small-world networks in the Euclidean space, on which the epidemics dynamics is investigated. A novel local region immunization strategy is proposed to suppress the epidemic prevalence on the Euclidean small-world...

This paper focuses on deriving optimal refill rules for a multi-purpose reservoir, and aims to maximize utilization benefits under the condition of flood control safety. The entire flood season is divided into multiple sub-seasons (i.e. pre-flood season, main-flood season and post-flood season)....

Biodiesel, an ideal alternative to fossil fuels, is very imperative for the sustainable development of mankind. Among its preparation technologies, biotechnological preparation is the most promising one. This study critically reviews the current progresses in biocatalysts (lipases),...

We study the acquisition and production planning problem for a hybrid manufacturing/remanufacturing system with core acquisition at two (high and low) quality conditions. We model the problem as a stochastic dynamic programming, derive the optimal dynamic acquisition pricing and production...

The stochastic pooling problem is a type of stochastic mixed-integer bilinear program arising in the integrated design and operation of various important industrial networks, such as gasoline blending, natural gas production and transportation, water treatment, etc. This paper presents a...

During anaerobic fermentation of waste activated sludge (WAS), the production of short-chain fatty acids (SCFAs), especially propionic acid which is considered as the most preferred carbon source for enhanced biological phosphorus removal, can be improved by controlling the suitable mass ratio...
