We study multi-period inventory control systems in which managers face seasonal demands with unknown distributions and make inventory decisions based on past demand data. It can be shown that a data-d...
Theoretical research indicates that natural selection will increase existing seasonal imbalances between the supply of nectar from flowers and the demand from bees and other insects.
Sand, spanning miles of beaches, carpeting vast oceans and deserts, is a visual metaphor for limitless resources. Yet researchers in this week’s journal Science seize another metaphor – sand in an ho...
Virtual 3D models of cities are now being extensively employed for the estimation of thermal energy demand at varying spatial and temporal scales. Efforts in preparing and management of the datasets r...
The Emilia 2012 sequence featured seven events of moment magnitude (M) >5, five of which occurred between May 20 and May 29, 2012. These earthquakes were structurally damaging over a wide area. The da...
In India, water resources are governed by the southwest monsoon. The water demand is increasing day by day due to population growth, rapid urbanisation, and multiple cropping practices. Due to changin...

Bertrand competiton has been a prominent paradigm for the empirical study of differentiated product markets for at least twenty years. Firms engaged in Bertrand competition maximize profits by choosi...
This article contains order level inventory models for deteriorating items with quadratic demand. The finite production rate is proportional to the demand rate and the deterioration is time proportion...
This paper deals with the development of an inventory model for Weibull deteriorating items in quadratic demand market when delay in payments is allowed to the retailer to settle the account against t...
This paper deals with development of an inventory model when the deterioration rate follows Weibull two parameter distributions. Here it is assumed that demand rate is a function of selling price and ...
Pontryagin minimum principle (PMP) is applied in this paper to find the optimal control of the reverse logistics model of a production inventory system with deteriorating items. The total cost of the ...
Using on-demand coherence conversion via optical locking in conventional stimulated (three-pulse) photon echoes, ultralong, ultraefficient photon storage has been observed in a rare-earth Pr3+ doped Y...
We propose a scalable neutral atom quantum computer with an on-demand interaction. Artificial lattice of near field optical traps is employed to trap atom qubits. Interactions between atoms can be tu...
