Although the clinical pathway (CP) predefines predictable standardized care process for a particular diagnosis or procedure, many variances may still unavoidably occur. Some key index parameters have strong relationship with variances handling measures of CP. In real world, these problems are highly nonlinear in nature so that it’s hard to develop a comprehensive mathematic model. In this paper, a...
Aimed at the variations of CP, combined modular modelling method and structure changing mechanisms, a modular colored Petri net with changeable structure (MCPN-CS) workflow modelling method is proposed. A new type of place, namely signal place, is added into the MCPN-CS to respond the variation states of CP. Meanwhile, a hybrid variation monitoring and an analyzing and reasoning controller are designed...
