‘Horses for Courses’ in demand forecasting

Petropoulos, Fotios; Makridakis, Spyros; … - In: European Journal of Operational Research 237 (2014) 1, pp. 152-163

Forecasting as a scientific discipline has progressed a lot in the last 40years, with Nobel prizes being awarded for seminal work in the field, most notably to Engle, Granger and Kahneman. Despite these advances, even today we are unable to answer a very simple question, the one that is always...

A simulation based approximate dynamic programming approach to multi-class, multi-resource surgical scheduling

Astaraky, Davood; Patrick, Jonathan - In: European Journal of Operational Research 245 (2015) 1, pp. 309-319

This paper presents a model and solution methodology for scheduling patients in a multi-class, multi-resource surgical system. Specifically, given a master schedule that provides a cyclic breakdown of total OR availability into specific daily allocations to each surgical specialty, the model...

A family of composite discrete bivariate distributions with uniform marginals for simulating realistic and challenging optimization-problem instances

Reilly, Charles H.; Sapkota, Nabin - In: European Journal of Operational Research 241 (2015) 3, pp. 642-652

We consider a family of composite bivariate distributions, or probability mass functions (pmfs), with uniform marginals for simulating optimization-problem instances. For every possible population correlation, except the extreme values, there are an infinite number of valid joint distributions...
