Mean-Based Error Measures for Intermittent Demand Forecasting
S. D. Prestwich, R. Rossi, S. A. Tarim +1
To compare different forecasting methods on demand series we require an error measure. Many error measures have been proposed, but when demand is intermittent some become inapplica…
Piecewise linear approximations of the standard normal first order loss function
Roberto Rossi, S. Armagan Tarim, Steven Prestwich +1
The first order loss function and its complementary function are extensively used in practical settings. When the random variable of interest is normally distributed, the first ord…
Forecasting Intermittent Demand by Hyperbolic-Exponential Smoothing
S. D. Prestwich, S. A. Tarim, R. Rossi +1
Croston's method is generally viewed as superior to exponential smoothing when demand is intermittent, but it has the drawbacks of bias and an inability to deal with obsolescence,…
A unified modeling approach for the static-dynamic uncertainty strategy in stochastic lot-sizing
Roberto Rossi, Onur A. Kilic, S. Armagan Tarim
In this paper, we develop mixed integer linear programming models to compute near-optimal policy parameters for the non-stationary stochastic lot sizing problem under Bookbinder an…
