### Maximum on a random time interval of a random walk with infinite mean

Let $$\xi _1,\xi _2,\ldots$$ξ1,ξ2,… be independent, identically distributed random variables with infinite mean $${\mathbf {E}}[|\xi _1|]=\infty .$$E[|ξ1|]=∞. Consider a random walk $$S_n=\xi _1+\cdots +\xi _n$$Sn=ξ1+⋯+ξn, a stopping time \tau …

### Limiting the oscillations in queues with delayed information through a novel type of delay announcement

Many service systems use technology to notify customers about their expected waiting times or queue lengths via delay announcements. However, in many cases, either the information might be delayed or customers might require time to travel to the …

### Batch service systems with heterogeneous servers

Bulk-service multi-server queues with heterogeneous server capacity and thresholds are commonly seen in several situations such as passenger transport or package delivery services. In this paper, we develop a novel decomposition-based solution …

### Stability of JSQ in queues with general server-job class compatibilities

We consider Poisson streams of exponentially distributed jobs arriving at each edge of a hypergraph of queues. Upon arrival, an incoming job is routed to the shortest queue among the corresponding vertices. This generalizes many known models such …

### Stein’s method for diffusive limits of queueing processes

Donsker’s theorem is perhaps the most famous invariance principle result for Markov processes. It states that, when properly normalized, a random walk behaves asymptotically like a Brownian motion. This approach can be extended to general Markov …

### Über diese Zeitschrift

Queueing Systems: Theory and Applications (QUES) is a well-established journal focusing on the theory of resource sharing in a wide sense, particularly within a network context. The journal is primarily interested in probabilistic and statistical problems in this setting.

QUES welcomes both papers addressing these issues in the context of some application and papers developing mathematical methods for their analysis. Among the latter, one would particularly quote Markov chains and processes, stationary processes, random graphs, point processes, stochastic geometry, and related fields.

The prospective areas of application include, but are not restricted to production, storage and logistics, traffic and transportation, computer and communication systems.
