On-Demand Services Composition and Infrastructure Management
نویسندگان
چکیده
This paper presents several engineering applications that involve distributed software services. Due to the complexity of these applications, an efficient and flexible service composition framework is needed. A reference service composition framework is introduced to address two issues prevailing in current service composition: interface incompatibility and performance. The reference framework applies active mediation to enhance efficient execution of applications employing composed services. As the number of services becomes large, the composed application imposes challenge on the service infrastructure management. A reliability model is introduced for building an automatic infrastructure management paradigm.

متن کاملStrategies to Overcome Network Congestion in Infrastructure Systems
Networked Infrastructure systems deliver services and/or products from point to point along the network. Demand for the services provided by such systems is typically cyclic, creating inefficiencies in capacity utilization. Congestion pricing provides incentives to shift demand from peak time periods to lower demand periods. This effectively increases the capacity of the system without the need...

متن کاملIdentification of the Healthcare Services with Potential Induced Demand
Background and Objectives: Induced demand in healthcare is referred to as provision of unnecessary services or the patient by health services providers, while the patient is not aware of their unnecessity. Apart from being unethical, this practice can potentially disturb the supply and demand balance in the health market, pose financial load on the patient, thread the patient’s health by imposi...
