With the development of SaaS, the business process is also provided to tenants as a software service, and the business process provided in the SaaS mode needs to ensure that a plurality of tenants share one business process system, but can provide the business process meeting the personalized requirements of the tenants according to the difference of their business requirements. The solutions commonly used for business process customization at present mainly include a customization method based on variable points, a customization method based on templates and a customization method based on variability models. The method for customizing based on the variable point designs a part needing to be customized in the process into the variable point, the variable point comprises a plurality of selectable items, and the tenant can select the selectable items according to the self requirement to finally form the complete business process; the template-based customization method comprises the steps that a template flow is obtained from a flow template DB, then a flow customization module carries out customization operation on customization points, the customization operation range is limited in customization constraints and comprises a node addition range, a node dependence rule, whether nodes can be deleted and the like, and after customization is finished, a customized flow is stored in the customization flow DB for a tenant through a deployment module; a customization method based on a variability model designs variation points and variants in the model, tenants select the variants to generate a process configuration file object, and specific business process instances are derived during operation.

step 3.1 for variability task nodes, analysis selectionTask node T in certain business sub-processiThen, the subsequent flows are divided into several mutually exclusive categories according to the actual requirements of the services, and a regular expression is set for each category as the judgment of the gateway branches;
step 3.2, setting different weights for the variable task nodes according to the hierarchy of the business sub-processes, wherein the weight of the first business sub-process is 1, then increasing by a multiplying power of 10, setting the weight for each sub-process in sequence, and setting a natural number weight for the task nodes in the business sub-processes, wherein 1 is taken as an initial value from top to bottom and the natural number weight is increased in sequence;
and 3.3, adding a routing node in the business process model according to the condition of the divided variability task nodes.
9. The method according to claim 6, wherein the matching degree calculation formula in step 4 is:
Wherein wiIs the weight, v, of the selected ith business sub-processijFor the jth task node T in the selected ith business subprocessijAnd (4) corresponding weight values.
10. Step 3 according to claim 8 further comprises a sub-step, characterized in that, in step 3.1, a regular expression is set for each category, the regular expression is a character string shaped like ". times.11", and 1 is used to match whether a certain business sub-process is selected.
