To Control or not to Control
Odysseas Kanavetas, Camiel M. P. Koopmans, Floske M. Spieksma
We introduce a model with control vacations instead of standard queueing control systems with permanent control. The researched model is an M/M/1 queue with temporary periods of se…
The Value of Temporary Control for the M/M/1 Queue
Odysseas Kanavetas, Camiel M. P. Koopmans, Floske M. Spieksma
In this article, a one-off option for temporary service rate control for the M/M/1 queue is considered. After taking this option, during a single exponentially distributed period,…
Two-Product Make-to-Stock System: Strategic Joining and Optimal Inventory Levels
Odysseas Kanavetas, Ekaterina Kosarevskaia
This paper analyzes a two-product make-to-stock queueing system where a single production facility serves two customer classes with independent Poisson arrivals. Customers make str…
Ameso Optimization: a Relaxation of Discrete Midpoint Convexity
Wen Chen, Odysseas Kanavetas, Michael N. Katehakis
In this paper we introduce the Ameso optimization problem, a special class of discrete optimization problems. We establish its basic properties and investigate the relation between…
Inventory Policies for Two Products under Poisson Demand: Interaction between Demand Substitution, Limited Storage Capacity and Replenishment Time Uncertainty
Apostolos N. Burnetas, Odysseas Kanavetas
We consider a two-product inventory system with independent Poisson demands, limited joint storage capacity and partial demand substitution. Replenishment is performed simultaneous…
