内容简介:

We investigate an online learning and optimization problem for queueing systems in a data-driven environment, i.e. the model parameters are unknown a prior. Service provider’s objective is to seek the optimal service fee and service capacity so as to maximize the cumulative expected profit (the service revenue minus the capacity cost and delay penalty). We develop a framework to developing online learning algorithms that effectively evolve the service provider’s decisions utilizing real-time data including customers’ arrival and service times for a variety of queueing systems. Effectiveness of these online learning algorithms is substantiated by (i) theoretical results including the algorithm convergence and analysis of the regret, i.e. the cost to pay over time for the algorithm to learn the optimal policy, and (ii) engineering confirmation via simulation experiments of a variety of representative examples. The talk is based on joint works with Yunan Liu from NCSU and Guiyu Hong from CUHK-Shenzhen.
