A Context-aware Workflow System Framework and Scheduling Algorithm

In the pervasive and mobile computing environment, work∞ow and context information are closely linked, work∞ow management system have to interact with a variety of sensors. Therefore, the design and development context-aware work∞ow applications become complex and di‐cult to migrate to other platforms. In order to simplify the development of context-aware work∞ow applications and enhance its portability, a new context-aware work∞ow framework is proposed in this paper. This framework introduced into the context-aware middleware which shielded the various bottom sensors work details for the applications and make the work∞ow applications focus on using high-level context, so as to realize the intelligent work∞ow management. This framework also introduced into an ant colony optimization based scheduling algorithm for context-aware work∞ow. Performance test shows that the algorithm can quickly output scheduling results of the middle-scale problems.

Estimating operational risk indices for software services outsourcing industry: a case

Software Services Outsourcing (SSO) industry has grown rapidly in the last few decades in undertaking software projects. Projects are grouped with several other projects according to some similarity, for example same customer, same domain, same geography, or some other factor(s). When an SSO enterprise undertakes concurrent execution of multiple projects characterised by size, complexity, resource requirements, etc. in multiple locations, it is necessary to estimate 'generic risk factors'. Although generic risk factors are used in medical/actuarial science, so far they have not been applied in SSO industry and therefore have not been mandated in the existing IT-related standards; which currently focus on project-specific risk factors. In this paper, we demonstrate the use of generic risk factors by developing a computational and workflow system framework. Such a framework may be used to upgrade existing international standards on project risk management.
