Newsvendor models with random supply capacity and backup sourcing
Papachristos I., Pandelis D.G. (2022)We consider newsvendor models with a primary supplier whose production is subject to random capacity. In order to hedge against this supply risk the retailer contracts with a reliable backup supplier to reserve capacity ... -
On the optimal use of a slow server in two-stage queueing systems
Papachristos I., Pandelis D.G. (2017)We consider two-stage tandem queueing systems with a dedicated server in each queue and a slower flexible server that can attend both queues. We assume Poisson arrivals and exponential service times, and linear holding ... -
Optimal Dynamic Allocation of Collaborative Servers in Two Station Tandem Systems
Papachristos I., Pandelis D.G. (2019)We consider two-stage tandem queueing systems with one dedicated server in each station and a flexible server that can serve both stations. We assume exponential service times, linear holding costs accrued by jobs present ... -
Optimal server assignment in a two-stage tandem queueing system
Papachristos I., Pandelis D.G. (2020)We study Markovian queueing systems consisting of two stations in tandem. There is a dedicated server in each station and an additional server that can be assigned to any station. Assuming that linear holding costs are ...
