Infrastructure is a means to an end: it is built, maintained and expanded in order to enable the functioning of society. Present infrastructure operation is characterised by: governance based on unmanaged growing demand, which is both inefficient and ultimately unsustainable; lack of integration of the end-users, in terms of the variety of their wants, needs and behaviours; separate and paralle...

We present a novel approach for multi-channel operation (MCO) in vehicular communication systems, which allows for efficient utilization of the available bandwidth by asynchronous channel switching and enables dynamic service provisioning and usage by means of service advertisements. The proposed solution – Service-Actuated Multi-Channel Operation (SAMCO) – provides a logic that controls the pr...

The increasing need for support and the fragmented nature of the service system challenge us to develop services for children and their families. Child and family services are provided by the public, private and third sectors, which according to research have little or no reciprocal co-operation. The review produced information on co-operation interventions used by service providers in the fiel...

We study the problem of scheduling activities of several types under the constraint that at most a xed number of activities can be scheduled in any single time-slot. Any given activity type is associated with a service cost and an operating cost that increases linearly with the number of time-slots since the last service of this type. The problem is to nd an optimal schedule that minimizes the ...

Recent information systems have become large and complex by interacting with each other via networks. This makes assuring dependability of systems much more difficult than ever before. For this problem, we observe that requirement elicitation and risk analysis methods should be tightly connected with assurance methods. Furthermore, requirements should be ensured also in operation in such open e...

As a way to compose independent service together to fulfill a function, service composition is an important means for flexible and rapid information integration of complex distribution application in open and heterogeneous environment. However, the diversity of requirements makes it difficult to guarantee the correctness of service composition. This paper proposes a hierarchical dynamic service...

The current taxi operation mode features high ratio of vacant taxies roaming the streets, while lots of potential customers complaining being unable to find a taxi. The major reason for this inefficiency is that the current taxi dispatch system is incapable of exchanging information between taxi drivers, customers and the dispatch system in a real-time manner. This paper presents an approach to...

Service capability and matching degree of transfer facilities are directly related to the operational efficiency and safety of a subway station. Owing to differences in planning and construction, the transfer subway stations in developing countries have some defects in facility size and serviceability, which cause a decline in service performance, operation efficiency, and security level. In or...
