In social interaction, customers can observe the number of other customers receiving service and select queues with more customers. Simultaneously, customers in the queue anticipate waiting times and worry about utility loss. This study explores the impact of loss aversion psychology on customer queuing strategies, service provider pricing, and rev...

In social interactions, customer decisions are often influenced by the behavior of others. When multiple customers make the same purchasing decision within a socially interactive environment, their perceived utility of the service increases. Additionally, customers develop a reference time utility based on their patience time and the expected waiti...

Some online retailers, based on traditional channels, have launched live-streaming channels. To study the optimal live-streaming choices of online retailers, this paper models the supply chain composed of a manufacturer and an online retailer by establishing three modes: no live-streaming mode, influencer live-streaming mode, and retailer self-live...

Nowadays, in live streaming e-commerce, brands have two live-streaming modes, i.e., the brand self-live streaming mode(S model) and the influencer live-streaming mode (I model). In this paper, considering the perceived difference of consumers in product dispatching time and the resulting return behavior, we construct a game model to study the optim...

Purpose Customers will develop a stronger desire to purchase when more people are waiting in line for service due to the herding effect. However, this also leads to longer queue times, causing customers to experience a waiting patience time. This study examines these two psychological aspects of delay-sensitive customers in service systems, conside...

The authors consider an M/M/1 queue with two types of customers, where customers are classified into two categories according to their psychological feelings when facing uncertainty about queue information. In the unobservable queue, experienced customers could accurately calculate their expected utilities, while first-time customers are loss-avers...

Waiting is a major factor influencing the perception of delay-sensitive customers in the service industry. In the process of queueing, some customers often have a psychological expectation of waiting time in the face of uncertain delay information, so that customer service utility depends not only on the actual waiting time, but also on the relativ...

In many service settings, customers are usually unaware of service-related information. Therefore, in such service systems, customers can only resort to online ratings posted on the review platforms to obtain the user-generated service information and make their joining/balking decisions depending on their service value assessment (consumption util...

As the mobile Internet improves by leaps and bounds, the model of traditional offline used car trading has gradually lost the ability to live up to the needs of consumers, and online used car trading platforms have emerged as the times require. Second-hand car price assessment is the premise of second-hand car trading, and a reasonable price can re...

In this paper, we focus on a kind of many-to-many matching system which is applicable to many real-life matching systems. We use customers and servers to represent the inputs at both ends. To portray the inputs’ behavioral features in many actual matching service systems, we introduce the customer impatience and flexible matching mechanism. Conside...

The application of blockchain technology solves the trust problem between core enterprises (CEs), small and medium-sized enterprises (SMEs), and commercial banks, facilitating CEs and commercial banks to provide guarantee for SMEs and finance them, respectively. This study considers a three-level supply chain composed of a manufacturer, a distribut...

In service industries, especially in some ticket windows at scenic spots, affected by congestion, some customers often find excuses or ask the acquaintances in the queue so as to jump the queue and complete their corresponding service as early as possible. In this paper, we model the queueing phenomenon in the ticket windows at scenic spots as a sp...

An increasing number of manufacturers are introducing voluntary carbon emission reduction (VCER) mechanisms, such as clean development mechanisms (CDMs), to reduce environmental pollution and fulfill their social responsibility goals. In this paper, we build and compare two types of competitive supply chain models, specifically, a model with a mono...

In this paper, we study the equilibrium strategies of heterogeneous delay sensitive individuals in matching systems. Take customers as the research object. The priorities hinge on the magnitude of customers’ admission fee. Before entering the system where there are no servers, customers will make a two-stage strategy. First, customers should determ...

In recent years, queueing models with service interruption have been studied extensively due to their widespread applications. This paper is devoted to the study of an M/M/1 queue with a particular service interruption discipline under two types of the maintenance activities, namely the reactive maintenance and the planned maintenance. In the proce...

During the past few years, batch service systems have attracted considerable attention due to their wide area of applications. In this present paper, we study a special batch service polling system (the so-called Israeli queue) with priorities. Different from the previous papers which focus on the performance analysis, we aim to investigate the str...

The existing tollbooth systems with multi-type vehicles in transportation literature typically assume the servers are either dedicated for each vehicle type or generic for all vehicle types. Conversely, in this paper, we focus on studying two similar systems both with skill-based servers, i.e., each tollbooth can handle a given subset of vehicle ty...

This study examines a matching queue problem (double-sided matching queue) where customers are loss-averse with respect to their waiting times. We first set the reference point and construct the loss-averse customers' utility function, then we investigate the customers' strategic behaviour regarding their joining or balking dilemma, with reference...

In some queueing systems, customers are frequently asked for giving a service quality feedback for their service at their service completion instants. Based on this phenomenon, in this paper, we model this type of queueing systems as clearing queues with service quality feedback and system maintenance. Once the system receives an unsatisfied (negat...

Purpose This paper aims to consider a single server queue with system disasters and impatience behavior are evident in our daily life. For this purpose, authors require to know the general behavior of these systems. Transient analysis shows for us how the system will operate up to some time instant t . Design/methodology/approach In this paper, au...

This study examines service systems with transfers of customers in an alternating environment. We model the service system as a two-server two-parallel queue (primary and auxiliary queues), that has various applications especially in manufacturing and healthcare systems. We establish a sufficient stability condition, and based on the censoring tech...

In this paper we consider a batch matching system with impatient servers and boundedly rational customers, which is essentially a double-ended batch service system. Each server is responsible for a batch of customers and serves them instantaneously. Especially, we assume that the servers have the characteristic of ”impatience”, which will lead to i...

This paper considers a tollbooth system with two parallel heterogeneous servers and two vehicle types (say, cars and trucks), where one server collects tolls from vehicles of both types and the other only serves one type of them. With such characteristic, the system is referred to as “skill-based servers” for brevity in this paper. Meanwhile, vehic...

In this paper, we study the discrete-time MAP/PH/1 queue with multiple working vacations and finite buffer N . Using the Matrix-Geometric Combination method, we obtain the stationary probability vectors of this model, which can be expressed as a linear combination of two matrix-geometric vectors. Furthermore, we obtain some performance measures inc...

Do [European Journal of Operational Research, 247, 672-675] discussed a tollbooth tandem queue with two heterogeneous servers, where customers arrive the system according to a Poisson process and the service times at the two heterogeneous servers follow an exponential distribution. In this present paper, we aim to consider a tollbooth tandem queue...

In this paper, we consider a single-server multi-queue polling system with unlimited-size batch service (so called ‘Israeli queue’) operating in a multi-phase random environment. The polling system consists of a service region and a waiting region, and the external environment evolves through time, i.e., when the external environment is in state i,...

This paper is devoted to the study of a clearing queueing system with a special discipline. As soon as the server receives N negative feedbacks from customers, all present customers are forced to leave the system and the server undergoes a maintenance procedure. After an exponential maintenance time, the system resumes its service immediately. Usin...

This paper studies a single server queueing model in a multi-phase random environment with server breakdowns and geometric abandonments, where server breakdowns only occur while the server is in operation. At a server breakdown instant (i.e., an abandonment opportunity epoch), all present customers adopt the so-called geometric abandonments, that i...

This paper deals with an M / G / 1 queue with vacations and multiple phases of operation. If there are no customers in the system at the instant of a service completion, a vacation commences, that is, the system moves to vacation phase 0. If none is found waiting at the end of a vacation, the server goes for another vacation. Otherwise, the system...

This paper considers a single server queueing system with working breakdowns and delaying repair under a Bernoulli-schedule-controlled policy. At a breakdown instant, the system either goes to repair period immediately with probability p, or continues to provide auxiliary service for the current customers with probability q = 1 − p. While the syste...

In this paper, we study a limited clearing queueing model with an orbit and non-persistent customers, in which the space of service station is finite and the server can serve all customers in the service station simultaneously. If a customer (new arrival or retrial) finds the station is full, he/she will decide whether join the orbit or not with re...

Perel and Yechiali 2014 considered a multi-queue single-server retrial polling system with batch service of an unlimited size, i.e., the so called "Israeli queue" with retrial, where the system consists of a main queue and an orbit queue, and only the customer at the head of the orbit queue is allowed to try to access the main queue. In this presen...

This paper considers a multi-server polling system with batch service of an unlimited size, i.e., the so called "Israeli queue" with multi-server, where the service rate of each server switches between a low and a high value depending on the number of groups standing in front of the servers upon its service completion. By means of matrix geometric...

Melange et al. (2016) investigated a continuous-time queueing system with two types of customers each having their own dedicated server, where the two dedicated servers are in parallel and have different service rates, meanwhile, the system adopts a global First-Come-First-Served (gFCFS) service discipline, i.e., all new arrivals queue together in...

This paper studies a system consisting of two parallel queues with transfers of customers. In the system, one queue is called main queue and the other one is called auxiliary queue. The main queue is monitored at exponential time instances. At a monitoring instant, if the number of customers in main queue reaches L \((>K)\), a batch of \(L-K\) cust...

In this paper, we study a single server GI/M/1 queue in a multi-phase service environment with disasters, where the disasters occur only when the server is busy serving customers. Whenever a disaster occurs in an operative service phase, all present customers are forced to leave the system simultaneously, the server abandons the service and an expo...

In this paper, we consider a GI/M/1 queue in a multi-phase service environment with disasters and working breakdowns. When the server is working in any normal service phases, it may suffer disastrous interruptions, causing all present customers to leave the system. At an exponential failure instant, the system becomes defective, and goes directly t...

This paper studies an M/G/1 queue in a multi-phase random environment. When in operative phase i, , the system is subject to disastrous interruptions, causing all present customers (waiting and served) to leave the system. At an exponential failure instant, the server abandons the service and the system goes directly to repair phase. After an expon...

This paper studies a single server M/G/1 stochastic clearing queue operating in a 3-phase environment, where the time length of the first and third phase are assumed to follow exponential distributions, and the time length of the second phase is a constant value. At the completion of phase 1, the system moves to phase 2, and after a fixed time leng...
