After sales services for repairable parts with service level agreements
… inventory systems for repairable-parts with service level consideration are studied. The first study develops a multi-parts inventory system and transportation decisions. A failed part might be repairable at the stock location, or at repair facilities, or it might be non repairable, which …

A Management System for Service level Agreements in Grid based Systems
… management is needed to support Quality of Service (QoS) requirements. The Distributed Aircraft Maintenance Environment (DAME) is an example of a Grid based system in which users wish to attach application QoS requirements. In light of this, an adaptive SLA (Service Level Agreement) …

Improving service level agreements for a job scheduler by visualizing simulations
… do not have a good way to generate suitable Service Level Agreements (SLAs), which means that they cannot accurately communicate their intentions to the job scheduler. This means that the owner's job might not finish on time or at all. The solution described in this thesis helps users …

Ensuring Service Level Agreements for Composite Services by Means of Request Scheduling
Building distributed systems according to the Service-Oriented Architecture (SOA) allows simplifying the integration process, reducing development costs and increasing scalability, interoperability and openness. SOA endorses the reusability of existing services and aggregating them into new service …

QUANTIFYING THE COST OF DATA CENTER COOLING APPROACHES INCLUDING SERVICE-LEVEL AGREEMENTS
… penalties associated with downtime defined in Service-Level Agreements (SLAs). This research addresses this gap by creating a model that integrates capital and operational costs with a stochastic discrete-event simulator for maintenance, failures, repairs, and availability. By quantifying …

The BabelNEG System - A Protocol-generic Infrastructure for Electronic SLA Negotiations in the Internet of Services
Visions of the next-generation Internet of Services are driven by digital resources traded on a global scope. For the resulting economic setting, automated on-line techniques for handling services and resources themselves, for advertising and discovering as well as for the on-the-fly negotiation of …
