Process model construction method, diagnosis and treatment method, system, equipment and medium

The invention provides a process model construction method, a diagnosis and treatment method, a system, equipment and a medium. The construction method comprises the following steps: acquiring a plurality of pieces of initial activity track data in a preset medical process; wherein each piece of initial activity track data comprises a plurality of activities of the corresponding patient in the preset medical process and time corresponding to each activity; performing homogeneity evaluation on the initial activity trajectory data based on a preset index to obtain target activity trajectory data; and constructing a process model based on the target activity trajectory data. According to the method, the homogeneity evaluation is performed on the initial activity trajectory data of the plurality of patients in the preset medical process through the preset indexes to obtain the target activity trajectory data, and the process model is constructed according to the target activity trajectory data, so that the qualit
