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…
On the stochastic inventory problem under order capacity constraints
Roberto Rossi, Zhen Chen, S. Armagan Tarim
We consider the single-item single-stocking location stochastic inventory system under a fixed ordering cost component. A long-standing problem is that of determining the structure…
Controlling inventory on electric roads
Alejandro Gutierrez-Alcoba, Roberto Rossi, Belen Martin-Barragan +1
Electric road systems (ERS) are roads that allow compatible vehicles to be powered by grid electricity while in transit, reducing the need for stopping to recharge electric batteri…
Computing Optimal (R, s, S) Policy Parameters by a Hybrid of Branch-and-Bound and Stochastic Dynamic Programming
Andrea Visentin, Steven Prestwich, Roberto Rossi +1
A well-know control policy in stochastic inventory control is the (R, s, S) policy, in which inventory is raised to an order-up-to-level S at a review instant R whenever it falls b…
MILP Approximations for non-stationary stochastic lot-sizing under (s,Q)-type policy
Xiyuan Ma, Roberto Rossi, Thomas Welsh Archibald
This paper addresses the single-item single-stocking location non-stationary stochastic lot-sizing problem under a reorder point -- order quantity control strategy. The reorder poi…
A dynamic ordering policy for a stochastic inventory problem with cash constraints
Zhen Chen, Roberto Rossi
This paper investigates a stochastic inventory management problem in which a cash-constrained small retailer periodically purchases a product from suppliers and sells it to a marke…
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…
