Domain Extensions of the Erlang Loss Function: Their Scalability and Its Applications to Cooperative Games

Abstract: We prove that several extensions of the classic Erlang loss function to non-integral numbers of servers are scalable: the blocking probability as described by the extension decreases when the offered load and the number of servers s are increased with the same relative amount, even when scaling up from integral s to non-integral s. We use this to prove that when several Erlang loss systems pool their resources for efficiency, various corresponding cooperative games have a non-empty core.

“…Hence, by Theorem 3, the proportional allocation P ( φ ) is a coalitionally rational allocation for the associated single‐attribute game ( N , c φ ) . This result was also derived by Karsten et al using an alternative proof. ◊EXAMPLE (EOQ games): Consider a set N of players (e.g., retailers) who have to meet deterministic demand for items (e.g., office supplies) occurring at a constant rate.…”

“…As pointed out by Özen et al , many of them fit the framework of an elastic single‐attribute situation. We mention EOQ inventory situations , ( S 1 , S ) inventory situations , M / M / s queueing situations , and M / G / s / s queueing situations . They are described in more detail in Section 2.3.…”

“…Some papers have considered resource pooling in the context of cooperative games, see e.g., Anily and Haviv (2010), Chakravarthy (2016), Karsten (2013), Karsten et al. (2009, 2011), Timmer and Scheinhardt (2013) and Yu et al. (2015).…”

“…Another line of literature treats each coalition as a multi-server loss system- Karsten et al (2012) considers the case where the number of servers with each player is fixed apriori, and Özen et al (2011), Karsten et al (2014) consider the case where a coalition optimizes the number of servers it operates. Finally, Karsten et al (2015) analyses the setting where each coalition is an M/M/s queue (Erlang C); they consider both the above mentioned models for the service capacity of a coalition.…”

“…Naturally, the resulting aggregate payoff must be divided between the providers in a stable manner, i.e., in such a way that no subset of providers has an incentive to 'break away' from the grand coalition. Such stable payoff allocations have been demonstrated in a wide range of settings, including single/multiple server environments, and loss/queue-based environments (see Karsten et al (2015Karsten et al ( , 2014 and the references therein). a significant extension; it includes an impossibility result under classical notions of stability (Section 3), an analysis of stable configurations under an extension of the Shapley value for partition form games (Section 4), a complete characterisation of stable configurations in heavy and light traffic regimes (Section 5), and a comprehensive numerical case study (Section 6).…”
