ABSTRACT : This paper analyzes an MX/G/1 queueing system where the server is subject to random breakdowns and the server applies the D-policy in providing the service. The steady-state queue size probability distribution is obtained using the...
ABSTRACT : In this paper, dynamic duopolistic Cournot models are investigated with discrete time scales under the assumption of unknown inverse demand function and linear cost. With this motivation, we consider different types of models: bounded...
ABSTRACT : In literature, several studies have been made to study conflict among duopolistic Cournot game with incomplete information. This paper attempts to investigate equilibrium stability of a nonlinear Cournot duopoly game on which cooperation...
ABSTRACT : We make further attempts to investigate equilibrium stability of a nonlinear Cournot duopoly game. Our studies in this paper focus on the cooperation that may be obtained among duopolistic firms. Discrete time scales under the assumption...
ABSTRACT : Isoelastic demand function have been used in literature to study the dynamic features of systems constructed based on economic market structure. In this paper, we adopt the so-called Cobb–Douglas production function and study its impact...
ABSTRACT: A high variance of the quality of High School Assessment System (HSAS) is posing challenges for higher education institutions to estimate the level of rigor of high school curriculum by examining students’ performance obtained through High...
ABSTRACT : The current paper introduces a discussion between two different scenarios of Cournot games. Based on parameters time-dependent, a price function and discrete time scale are used to establish two Cournot models. The first model which we...
ABSTRACT : We consider in this paper a bulk service, or quorum, queueing system. The server is unreliable and may break down while providing service. The admission to the system is controlled and some arrivals may be denied admission. The queueing...
ABSTRACT : In this paper, we investigate the bulk service queue with Bernoulli vacation schedule and restricted admissibility introduced and studied by Madan and Abu-Dayyeh, [Revista Investigacion Operacional, Vol.24, No.2, pp.113- 123, 2003]....
ABSTRACT : We present an iterative scheme based on the fixed-point approximation method, for the numerical calculation of the time-dependent mean number of customers and blocking probability functions in a nonstationary queueing network with multi-...
ABSTRACT : The nonstationary Erlang loss model is a queueing system consisting of a finite number of servers and no waiting room with a nonstationary arrival process or a time-dependent service rate. The Erlang loss model is commonly used to model...
ABSTRACT : Circuit-switched communication networks have been analyzed extensively in the stationary case, i.e. where the arrival and/or service rates are independent of time. In this paper, we study a circuit-switched network where the rates of...
ABSTRACT : We present a survey of the main results and methods of the theory of retrial queues, concentrating on Markovian single and multi-channel systems. For the single channel case we consider the main model as well as models with batch arrivals...
