A hybrid estimation of distribution algorithm for joint stratification and sample allocation
Mervyn O'Luing, Steven Prestwich, S. Armagan Tarim
In this study we propose a hybrid estimation of distribution algorithm (HEDA) to solve the joint stratification and sample allocation problem. This is a complex problem in which ea…
A Grouping Genetic Algorithm for Joint Stratification and Sample Allocation Designs
Mervyn O'Luing, Steven Prestwich, S. Armagan Tarim
Predicting the cheapest sample size for the optimal stratification in multivariate survey design is a problem in cases where the population frame is large. A solution exists that i…
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…
