The optimal action \(a_{1}^{*}\) (left) and \(a_{2}^{*}\) (right) vs. queue states b 1 and b 2 when g 1=1 and g 2=5. p 1=p 2=0.5, λ=0.05, τ=1, η=1, ξ o =4, and β=0.97. In this case, ξ o ≥2λ+η+τ and \(\beta \leq \frac {2(\tau -\lambda)}{\tau +\eta }\). According to Corollary 4.14, Theorem 4.13 holds. Therefore, both \(a_{1}^{*}\) and \(a_{2}^{*}\) are nondecreasing in (b 1,b 2)
