We consider a finite-horizon, periodic-review system for a perishable product at a retailer that faces stochastic, age-dependent demand and loses excess demand, if any. For this system, we build three models that capture two sources of unfilled demand, insufficient inventory and inappropriate...

Cloud bursting is a hybrid computing resource model in which a firm firstly uses its own internal computing resources and then bursts to a public cloud for extra resources as needed. This paper develops quantitative models to examine whether a firm who has on-site capacity can be benefited from...

This paper introduces the connotation of Human Development Index (HDI) and its dimensional indices, as well as the HDI comprehensive evaluation method based on entropy weight. And the specific formula and steps for calculation are put forward. This paper also selects the HDI dimensional indices...

We investigate intraday seasonality in, and relationships between, informational efficiency, volatility, volume and liquidity. Platinum and gold, both traded in overlapping sessions in Tokyo and New York, provide an interesting comparison because Tokyo is an internationally important trading...

A latent heat thermal energy storage (LHTES) system, which uses phase change materials (PCMs) as thermal storage medium, has attracted interests over the past decades due to its high energy storage density. However, a computationally efficient heat transfer model, which is essential for...

The efficient removal of arsenic from wastewater is still a challenge. In this paper, a heterojunction consisted of in-situ carbon-doped TiO2 and nitrogen deficiency g-C3N4 (C/TiO2@ND-C3N4) has been constructed, which can completely oxidize As(III) (10,000 μg/L, 40 mL) to As(V) within 12 min...
