The optimality of an (s, S) hiring policy on a workforce planning problem with fixed recruitment costs and binomial turnover
Zhen Chen, Roberto Rossi, Belen Martin-Barragan +1
We study a finite-horizon nonstationary workforce planning problem in which staff turnover in each period follows a binomial distribution whose parameters depend on the post-hiring…
A computational study for the inventory routing problem
Yasemin Malli, Marco Laumanns, Roberto Rossi +2
In this work we compare several new computational approaches to an inventory routing problem, in which a single product is shipped from a warehouse to retailers via an uncapacitate…
An (R, S) Based Heuristic Model for the Stochastic Joint Replenishment Problem
Mengyuan Xiang, Roberto Rossi, S. Armagan Tarim
This paper considers the periodic-review stochastic joint replenishment problem (JRP) under Bookbinder and Tan's static-dynamic uncertainty control policy. According to a static-dy…
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…
A comparison of non-stationary stochastic lot-sizing strategies
Gozdem Dural-Selcuk, Onur A. Kilic, S. Armagan Tarim +1
We consider the non-stationary stochastic lot sizing problem with backorder costs and make a cost comparison among different lot-sizing strategies. We initially provide an overview…
