A new class of queueing networks with \negative and positive" customers was introduced and shown to have a non-standard product form 4]; since then this model has undergone several generalizations 5, 6, 7, 8]. Positive customers are identical to the usual customers of a queueing network, while a negative customer which arrives to a queue simply destroys a positive customer. We call these genera...

Negative customers are an accepted means of removing jobs from systems in queueing theory. A lack of synchronization with causal events can adversely affect results. We introduce a formulation for a queue with unreliable servers in which the arrival of negative customers is synchronized with the processor breakdown. Probabilistic re-sampling on repair can also be modelled, resulting in an inter...

We consider a continuous review perishable (s, S) inventory system with a service facility consisting of a waiting line of finite capacity and a single server. Two types of customers, ordinary and negative, arrive according to a Markovian Arrival Process (MAP). An ordinary customer joins the queue and a negative customer removes some ordinary customers from the queue. Unlike the conventional me...

This paper investigates to what extent a recently developed new product form result for queueing networks with positive and negative customers fits into the class of product form queueing networks that satisfy a notion of partial or local balance. As such this paper investigates whether this new product form is still a consequence of an appropriate notion of local balance. To this end a new and...

In this paper, we consider an MAP/G/1 queue with MAP arrivals of negative customers, where there are two types of service times and two classes of removal rules: the RCA and RCH, as introduced in Section 2. We provide an approach for analyzing the system. This approach is based on the classical supplementary variable method, combined with the matrix-analytic method and the censoring technique. ...

This article considers a continuous review perishable (s,S) inventory system in which the demands arrive according to a Markovian arrival process (MAP). The lifetime of items in the stock and the lead time of reorder are assumed to be independently distributed as exponential. Demands that occur during the stock-out periods either enter a pool which has capacity N(<∞) or are lost. Any demand tha...

Intentional service failures (e.g., overbooking or overcharging) have received little scholarly attention, despite their regular occurrence and immense costs. Using a multi-method approach combining experimental field data from online reviews, it was found that intentional (vs. unintentional) lead to greater negative word of mouth (nWOM) patronage reduction. This research extends these findings...

The ongoing proliferation of digital technologies is reshaping the customer-firm relationship by providing new possibilities for companies and customers to interact with each other. Companies try to involve customers in firm-sponsored online customer networks to connect them more deeply with the brand. In this context, the impact of positive social influence induced among customers on their val...
