This special issue of Concurrency and Computation: Practice and Experience contains selected highquality papers from the Second International Workshop on Workflow Management in Service and Cloud Computing (WMSC2010) that was held on 11–13 December 2010 in Hong Kong [1]. The WMSC workshop series aims to provide an international forum for the presentation and discussion of research and developmen...

This paper presents the advances in developing a dynamic scheduling technique suitable for automating digital publishing workflows. Traditionally scheduling in digital publishing has been limited to timing criteria. The proposed scheduling strategy takes into account contingency and priority fluctuations. The new scheduling algorithm, referred to as QB-MUF, gives high priority to jobs with low ...

Workflow management systems should efficiently manage workflow constraints such as time, resource, and cost during workflow executions. Especially, workflow time management is important in timely scheduling of workflow process execution, avoiding deadline violations, and improving the workflow throughput. Though there have been some studies on the dynamic deadline management in a workflow, the ...

The need for scheduling algorithms arise from the requirement to perform multitasking, essentially for modern computing systems. Scheduling is the greatest cause that optimizes the objective function that involved with the selection of resources. In scheduling, every aspect of execution is based on decision(s). The general objective of scheduling algorithms is to effectively use the available p...

Recently cloud computing has gained popularity among e-Science environments as a high performance computing platform. From the viewpoint of the system, applications can be submitted by users at any moment in time and with distinct QoS requirements. To achieve higher rates of successful applications attending to their QoS demands, an effective resource allocation (scheduling) strategy between wo...

Scheduling tasks with precedence constraints on a set of resources with different performances is a well-known NP-complete problem, and a number of effective heuristics has been proposed to solve it. If the start time and the deadline for each specific workflow are known (for example, if a workflow starts execution according to periodic data coming from the sensors, and its execution should be ...

Cloud computing is outsourcing of computing resources over the Internet where we can be connected to remote locations and can use the services over the Internet at another location to store our important information. The cloud service requirements provide access to advanced software applications. In cloud computing, the network of remote servers is used to process data. Workflow scheduling is o...

One of the key applications of operational research in health systems management is to improve the mechanism of resource allocation and program planning in order to increase the system efficiency. This study seeks to offer an innovative method for the planning and scheduling of health service units with the aim of reducing the patients' Length of Stay (LOS) in the Cardiac Surgery Ward of Razavi...
