A stochastic card balance management problem with continuous and batch-type bilateral transactions

Barron, Yonit - In: Operations research perspectives 10 (2023), pp. 1-11

We study a stochastic continuous-review card balance management problem with two transaction patterns, namely, continuous and batch-type bilateral transactions, both in a Markovian environment. Motivated by the Autoload program used in public transit systems, the card is managed using a...
