Patient assignment scheduling in a cloud healthcare system based on petri net and greedy-based heuristic

Integrated system has been identified as one of must-do strategies in future healthcare. This paper focuses on a cloud healthcare system, which is a novel integrated healthcare system by the technique of Internet in very recent years. A Petri net is presented to describe the relationship among medical process and resources in this integrated healthcare system. To allocate the bottleneck medical resource of this system efficiently, a patient assignment scheduling problem is investigated and studied, in detail, a mathematical model is established and a greedy-based heuristic algorithm is designed. Experimental results validate the effectiveness of the proposed model and algorithm.
