Managing an assemble-to-order system with after sales market for components

Elhafsi, Mohsen; Hamouda, Essia - In: European Journal of Operational Research 242 (2015) 3, pp. 828-841

In this paper, we consider an assemble-to-order manufacturing system producing a single end product, assembled from n components, and serving an after sales market for individual components. Components are produced in a make-to-stock fashion, one unit at a time, on independent production...

A Tabu Search heuristic procedure in Markov chain bootstrapping

Cerqueti, Roy; Falbo, Paolo; Guastaroba, Gianfranco; … - In: European Journal of Operational Research 227 (2013) 2, pp. 367-384

Markov chain theory is proving to be a powerful approach to bootstrap finite states processes, especially where time dependence is non linear. In this work we extend such approach to bootstrap discrete time continuous-valued processes. To this purpose we solve a minimization problem to partition...

‘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...

Factor screening for simulation with multiple responses: Sequential bifurcation

Shi, Wen; Kleijnen, Jack P.C.; Liu, Zhixue - In: European Journal of Operational Research 237 (2014) 1, pp. 136-147

in a realistic simulation experiment. A specific method is sequential bifurcation (SB), which is a sequential method that …) second-order polynomials are adequate approximations of the input/output functions implied by the simulation model; (ii) the … important second-order effects either (heredity property). This paper examines SB for random simulation with multiple responses …

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...
