We study the design of a healthcare appointment system with a single physician and a group of patients whose service durations are stochastic. The challenge is to find the optimal arrival sequence for a group of mixed patients such that the total expected cost of patient waiting time and...

We demonstrate that lottery markets can exhibit the “hot-hand” phenomenon, in which past winning numbers tend to receive a greater share of the bets in future draws, even though past and future events are independent. This finding is surprising, as works by Clotfelter and Cook (1993) and...

This paper studies how to schedule medical appointments with time-dependent patient no-show behavior and random service times. The problem is motivated by our studies of independent datasets from countries in two continents which unanimously identify a significant time-of-day effect on patient...

This paper deals with the modeling of stochastic processes in long-term multi-stage energy planning problems when little information is available on the degree of uncertainty of such processes. Starting from simple estimates of variation intervals for uncertain parameters, such as energy demands...
