The maintenance of some sophisticated and complex equipment – for example, diagnostic equipment used in hospitals – is frequently outsourced to the original equipment supplier or another maintenance service provider. Companies that own such assets can either enter into a service agreement, or they can use service providers on a call-out basis. A fundamental problem for the provider of maintenan...

We analyze a single server queue with Poisson arrivals, two stages of heterogeneous service with different (arbitrary) service time distributions subject to random breakdowns and compulsory server vacations with general (arbitrary) vacation periods. After first-stage service the server must provide the second stage service. However, after the completion of each second stage service, the server ...

This article presents an explorative study of the impact of Communities of Practice (CoPs) on the success of a certain category of Knowledge Management Systems, hereafter called Expert Recommender Information Systems. They regroup Information Systems that identify and display individuals who have been qualified by the system as experts, and who are in a position to help users solve problems inv...

Present investigation deals with optimal management policy for Markovian queue with server breakdowns, vacations and setup. The customers arrive in Poisson fashion to get the service. The server may breakdown during the service and goes for repair immediately. By applying probability generating function technique queue length distribution is obtain for different states of the server. Further we...

This deliverable reports on the results of the WebSand work package on Secure Web Interaction. It provides a wording definition and technical specification of the term and builds the basis for the development of the server-side framework that achieves Secure Web Interaction.

This paper presents a new and efficient method to calculate point mobilities from subcomponents of a full structure. When performing dynamic analyses of subcomponents the result normally tends to strongly depend on the boundary condition selected for the component. The goal is to simulate the results one would have received if the full model would be analysed. Normally free or clamped boundary ...

This paper describes a study using mystery shoppers across multiple channels which investigated the traditional ‘line of visibility’ from service quality literature, and customer perceptions of organisational competencies “below the line”. We posited that in a multi-channel e-commerce environment, inconsistency or service breakdown above the line of visibility gives a negative impression of org...
