Reproducibility of Science is considered as one of the main principles of the scientific method, and refers to the ability of an experiment to be accurately reproduced, by third person, in complex experiment every detail matters to ensure the correct reproducibility. In the context of the ICCS 2011, Elsevier organized the executable paper grand challenge a contest to improve the way scientific ...

Bluetooth security has become increasingly important since Bluetooth is going to be used as a standard technology in wireless personal communication. This is especially true for Bluetooth applications that require strong security policies, e.g. mobile commerce applications. In this paper, a Bluetooth service-level security that allows easy implementation of flexible access policies is proposed....

We propose an RDF-based language called SWCL to represent contracts, with a focus on service level agreements. The language came about due to a requirement in our research concerning reliable service delivery in domains containing virtual organizations, and we describe one such domain. Our language is built around a production rule system using RDF bindings and containing some contract-specific...

Cloud computing that provides cheap and pay-as-you-go computing resources is rapidly gaining momentum as an alternative to traditional IT Infrastructure. As more and more consumers delegate their tasks to cloud providers, Service Level Agreements(SLA) between consumers and providers emerge as a key aspect. Due to the dynamic nature of the cloud, continuous monitoring on Quality of Service (QoS)...

In this paper, we study a logistics problem arising in military transport planning. A military organization operates a large fleet of vehicles in a depot to serve the requests of various operational units. Each request has a fixed start and end time, and is served by a prescribed number of vehicles. We address the following two problems: (1) how many vehicles are at least needed to meet a given...

In order to reduce costs, many enterprises have started to focus on their core business processes. As a consequence non-central business processes more and more are outsourced to external service providers. The relelationships between service providers and the service consumers are laid down in legal contracts called Service Level Agreements (SLAs). It is the task of the Service Level Managemen...

This paper studies outsourcing decisions for a two-level service process in which the first level serves as a gatekeeper for a second level of experts. The objective of the system operator (the client) is to minimize the sum of staffing costs, customer waiting costs, and mistreatment costs due to unsuccessful attempts by a gatekeeper to solve the customer’s problem. The client may outsource all...

Cloud manufacturing is a new paradigm which has been under study since 2010 and a vast body of research has been conducted on this topic. Among them, service composition problems are of utmost importance. However, most studies only focused on private clouds meaning the objective function is defined for just one component of the supply chain. This paper attempts to consider service composition p...

To some the next iteration of Grid and utility computing, Clouds offer capabilities for the high-availability of a wide range of systems. But it is argued that such systems will only attain acceptance by a larger audience of commercial end-users if binding Service Level Agreements (SLAs) are provided. In this paper, we discuss how to measure and use quality of service (QoS) information to be ab...

Research in the field of evacuation management puts a strong focus on the development of optimal evacuation and control strategies. However, in operational evacuation management the means to monitor, manage, evaluate and control are limited. The authorities nevertheless have a strong need to understand the system, in order to properly guide evacuating traffic. This indicates the need for a simp...
