We study stochastic inventory planning systems with lost sales and censored demand under stationary and non-stationary settings. Contrary to classical inventory theory, we assume that no knowledge of demand is initially available, and lost sales in each period are unobservable. We take a non-parametric approach and propose adaptive inventory policies that generate a sequence of ordering decisio...

Policy makers have now recognised the need to integrate thinking about climate change into all areas of public policy making. However, the discussion of ‘climate policy integration’ has tended to focus on mitigation decisions mostly taken at international and national levels. Clearly, there is also a more locally focused adaptation dimension to climate policy integration, which has not been ade...

Most of the inventory control models assume that quality defect never happens, which means production process is perfect. However, in real manufacturing processes, the production process starts its operation in the in-control state; but after a period of time, shifts to the out-of-control state because of occurrence of some disturbances. In this paper, in order to approach the model to real man...

While the horror of the Nazi medical experiments has been unanimously acknowledged, debate continues over whether results of those experiments which are scientifically sound should be used and cited in publications and, by extension, over whether any ethically-suspect research should be cited or published. The author consulted persons in such diverse disciplines as medical journalism, Holocaus...
