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…
A multi-period multi-product stochastic inventory problem with order-based loan
Zhen Chen, Ren-qian Zhang
This paper investigates a multi-product stochastic inventory problem in which a cash-constrained online retailer can adopt order-based loan provided by some Chinese e-commerce plat…
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…
Capital flow constrained lot sizing problem with loss of goodwill and loan
Zhen Chen, Ren-qian Zhang
We introduce capital flow constraints, loss of good will and loan to the lot sizing problem. Capital flow constraint is different from traditional capacity constraints: when a manu…
Single item stochastic lot sizing problem considering capital flow and business overdraft
Zhen Chen, Roberto Rossi, Ren-qian Zhang
This paper introduces capital flow to the single item stochastic lot sizing problem. A retailer can leverage business overdraft to deal with unexpected capital shortage, but needs…
