Approximate Optimality with Bounded Regret in Dynamic Matching Models
summary
Proves that, under paired arrivals and a single critical bottleneck, a constructed H-max-weight with threshold policy achieves asymptotic optimality with bounded regret versus a workload relaxation; analysis uses a one-dimensional workload relaxation and reflected-Brownian diffusion to pick the threshold, compares to MaxWeight and FCFS, and shows numeric gains on an N–N example. Assumptions: linear holding costs, knowledge of the bottleneck, connectivity and technical continuity; useful if the model’s paired-arrival and heavy-traffic limits match the application.
