In this paper, a newsboy model is developed under uniformly distributed lead-time and demand that is an appropriate assumption in obtaining optimal relief inventory of humanitarian disasters. It is noteworthy that limited historical data are in hand on relief operations. Hence, analytical and approximate solutions for optimal relief order quan­tity were derived. The effect of lead-time uncertai...

The coefficient of variation (CV), also known as relative standard deviation, has been used to measure the constancy Weber fraction, a key signature efficient neural coding in time perception. It long debated whether or not duration judgments follow Weber's law, with arguments based on examinations CV. However, what largely ignored this debate is that observed CVs may be modulated by temporal c...
