Bulk input queues with quorum and multiple vacations
Yellen, Jay; Dshalalow, Jewgeni H. (1995)The authors study a singleserver queueing system with bulk arrivals and batch service in accordance to the general quorum discipline: a batch taken for service is not less than r and not greater than R(≥r). The server ... 
Current Trends in Random Walks on Random Lattices
Dshalalow, Jewgeni H.; White, Ryan T. (202105)In a classical random walk model, a walker moves through a deterministic ddimensional integer lattice in one step at a time, without drifting in any direction. In a more advanced setting, a walker randomly moves over a ... 
Discrete and Continuous Operational Calculus in Stochastic Games
Iwezulu, Kenneth Ibe (201612)First, we consider a class of antagonistic stochastic games between two players A and B. The game is specified in terms of two "hostile" stochastic processes representing mutual attacks upon random times exerting casualties ... 
First excess levels of vector processes
Dshalalow, Jewgeni H. (1994)This paper analyzes the behavior of a point process marked by a twodimensional renewal process with dependent components about some fixed (twodimensional) level. The compound process evolves until one of its marks hits ... 
A First Passage Problem and its Applications to the Analysis of a Class of Stochastic Models
Abolnikov, Lev M.; Dshalalow, Jewgeni H. (1992)A problem of the first passage of a cumulative random process with generally distributed discrete or continuous increments over a fixed level is considered in the article as an essential part of the analysis of a class of ... 
A first passage problem and its applications to the analysis of a class of stochastic models
Abolnikov, Lev M.; Dshalalow, Jewgeni H. (1991)A problem of the first passage of a cumulative random process with generally distributed discrete or continuous increments over a fixed level is considered in the article as an essential part of the analysis of a class of ... 
First passage processes in Queuing system MX/Gr/1 with service delay discipline
Abolnikov, Lev M.; Dukhovny, Alexander M.; Dshalalow, Jewgeni H. (19920201)This article deals with a general singleserver bulk queueing system with a server waiting until the queue will reach level r before it starts processing customers. If at least r customers are available the server takes a ... 
Fixed point theory for Mönchtype maps defined on closed subsets of Fréchet spaces: the projective limit approach
Agarwal, Ravi P.; O'Regan, Donal; Dshalalow, Jewgeni H. (2005)New LeraySchauder alternatives are presented for Mönchtype maps defined between Fréchet spaces. The proof relies on viewing a Fréchet space as the projective limit of a sequence of Banach spaces. 
A FuriPera theorem in Hausdorff topological spaces for acyclic maps
Agarwal, Ravi P.; O'Regan, Donal; Dshalalow, Jewgeni H. (2004)We present new FuriPera theorems for acyclic maps between topological spaces. 
Generalized Random Measures on Topological Spaces
AlObaidi, Ali Hussein Mahmood (201905)Our work deals with classes of random measures on σcompact Hausdorff spaces perturbed by stochastic processes. We render a rigorous construction of the stochastic integral of functions of two variables and show that ... 
Lajos Takács and his work
Dshalalow, Jewgeni H.; Syski, Ryszard (19941001)This paper, written in honor of the 70th birthday of Lajos Takács, addresses his life and work, and includes some personal observations and appreciation of his contributions. In particular, it includes a short biography, ... 
Maintenance in SingleServer Queues: A GameTheoretic Approach
AlMatar, Najeeb; Dshalalow, Jewgeni H. (2009)We use antagonistic stochastic games and fluctuation analysis to examine a singleserver queue with bulk input and secondary work during server's multiple vacations. When the buffer contents become exhausted the server ... 
A nonmarkovian queueing system with a variable number of channels
Rosson, H. T.; Dshalalow, Jewgeni H. (2003)In this paper we study a queueing model of type GI/M/m̃a/∞ with m parallel channels, sonic of which may suspend their service at specified random moments of time. Whether or not this phenomenon occurs depends on the queue ... 
On a duality principle in processes of servicing machines with double control
Dshalalow, Jewgeni H. (1988)This paper examines a doubly controlled process of servicing machines. The classical system treated by Takács is equipped with m+1 unreliable machines served by one repairman. In the present modification of this model, the ... 
On a first passage problem in general queueing systems with multiple vacations
Dshalalow, Jewgeni H. (1992)The author studies a generalized singleserver queueing system with bulk arrivals and batch service, where the server takes vacations each time the queue level falls below r(≥1) in accordance with the multiple vacation ... 
On a multichannel queue with state dependent input flow and interruptions
Dshalalow, Jewgeni H. (1989)This paper deals with a multichannel queueing system with a finite waiting room but without losses. The latter is achieved by a temporary interruption of the input flow activity until the waiting room is ready to place a ... 
On a multichannel transportation loss system with controlled input and controlled service
Dshalalow, Jewgeni H. (1987)A multichannel loss queueing system is investigated. The input stream is a controlled point process. The service in each of m parallel channels depends on the state of the system at certain moments of time when input and ... 
On a singleserver queue with fixed accumulation level, state dependent service, and semimarkov modulated input flow
Russell, Gary; Dshalalow, Jewgeni H. (1991)The authors study the queueing process in a singleserver queueing system with state dependent service and with the input modulated by a semiMarkov process embedded in the queueing process. It is also assumed that the ... 
On applications of excess level processes to (N,D)policy bulk queueing systems
Dshalalow, Jewgeni H. (1996)The paper deals with queueing systems in which N and Dpolicies are combined into one. This means that an idle or vacationing server will resume his service if the queueing or workload process crosses some specified fixed ... 
On applications of Little's formula
Dshalalow, Jewgeni H. (1993)In classical Little's formula L=λW used in queueing, the parameter λ serves as the intensity of the input process. In various applications this parameter may not be known. The author discusses important classes of modulated ...
