Scheduling in Queueing Systems with Uncertain and Evolving Holding Costs

arXiv:2505.21331v2 Announce Type: replace-cross Abstract: In content moderation for social media platforms, the cost of delaying the review of a content is proportional to its view trajectory, which fluctuates and is apriori unknown. Motivated by such uncertain and evolving holding costs, we consider a queueing model where job states evolve based on a Markov chain with state-dependent instantaneous holding costs. We demonstrate that in the presence of such uncertain and evolving holding costs, the two canonical algorithmic principles, instantaneous-cost ($c\mu$-rule) and expected-remaining-cos

Why this matters
Why now

This paper addresses a fundamental challenge in AI applications like content moderation, where real-time costs are uncertain and dynamic, pushing the boundaries of existing queueing theory.

Why it’s important

Advanced scheduling algorithms handling uncertain evolving costs are crucial for scalable and fair operation of critical digital infrastructure, directly impacting platform efficiency and user experience.

What changes

The theoretical understanding and algorithmic principles for managing queues with non-stationary, state-dependent costs are refined, paving the way for more sophisticated AI-driven resource allocation.
