An Aspect-Oriented Service Orchestration for Nursing Scheduling Problem

Nursing scheduling problem (NSP) has been verified NP-Complete. The Nursing scheduling is a dynamic process interacting with parties iteratively to reflect the revised expectations and constrained rules. It is an orchestrating process which needs not only the scheduling algorithms and shifting methodologies but also the interaction and coordination. Based on web service orchestration in the NSP domain, it will provide a powerful solution to integrate human interactive chain and physical system process. For this reason, we propose a service orchestrating model for NSP that features: (1) Aspect-Oriented weaving; (2) Web Service Orchestration; and (3) scheduling expectation algorithm. In this model, it will weave expectation into scheduling process iteratively, and then provide an adaptable mechanism to fit the scheduling variability from repeatedly interaction.
