Self-service technologies (SSTs) are defined as technological interfaces that enable customers to produce a service without direct employee involvement. Among various SSTs, self-checkouts are being tested by grocery stores across the world. However, while most studies focus on SST adoption, there is limited research on its impact on service quality, customer satisfaction, and retention. Our stu...

Background There is limited evidence on the course of health service costs before and after psychiatric inpatient treatment, which might also be affected by source of cost data. Thus, this study examines: i) differences in health care costs before and after psychiatric inpatient treatment, ii) whether these differences vary by source of cost-data (self-report vs. administrative), and iii) predi...

Service composition is an important research problem in service computing systems, which combines simple and individual services into composite services to fulfill users’ complex requirements. Service composition usually consists of four stages, i.e., service discovery, candidate selection, service negotiation and task execution. In self-organising systems, there is the fifth stage of service c...

Cloud computing is becoming an interesting alternative as a flexible and affordable on-demand environment for deploying custom applications in the form of services. In this work, a self-organizing system model based on dynamic relation network is proposed. In the model, autonomic element can self-adapted to the weight of the relationship under the guidance of the self-organizing policy. Based o...

A multi-server infinite buffer queueing system with additional servers (assistants) providing help to the main when they encounter problems is considered as model of real-world systems customers’ self-service. Such are widely used in many areas human activity. An arrival flow assumed be novel essential generalization known Markov Arrival Process (MAP) case dynamic dependence parameters MAP on r...
