Abstract

Techniques are disclosed for modeling costs when editing a workflow process model. A request may be received to assign a cost factor to a workflow process step of the workflow process model, where the cost factor depends on a property of a processing environment that executes the workflow process model. Responsive to the request, the cost factor may be assigned to the workflow process step, such that a traversal of the workflow process step by a transaction invoking the workflow process model results in the cost factor being included in a total cost to be charged for executing the transaction.

Claims

1. A computer-implemented method, comprising:

providing a tool for editing a workflow process model comprising a plurality of workflow process steps, wherein the workflow process model is to be executed in a processing environment;

receiving, by the tool, a request to assign a cost factor to at least one workflow process step of the plurality of workflow process steps, wherein the cost factor depends at least in part on a property of the processing environment at a time that the workflow process model is executed in the processing environment; and

assigning the cost factor to the at least one workflow process step responsive to the request and by operation of one or more computer processors, such that a traversal of the at least one workflow process step by a transaction invoking the workflow process model results in the cost factor being included in a total cost to be charged for executing the transaction.

2. The computer-implemented method of claim 1, wherein the property of the processing environment characterizes a degree of resource utilization in the processing environment.

3. The computer-implemented method of claim 1, wherein the property of the processing environment comprises at least one of processor utilization, memory utilization, storage utilization, and network utilization in the processing environment.

4. The computer-implemented method of claim 1, wherein the cost factor further depends on a property of the transaction.

5. The computer-implemented method of claim 1, wherein the workflow process model further comprises branching logic comprising a precondition for traversing the at least one workflow process step.

6. The computer-implemented method of claim 5, wherein the total cost to be charged for executing the transaction is a function of which specific one or more workflow process steps of the workflow process model are traversed in executing the transaction.

7. The computer-implemented method of claim 5, wherein the precondition specifies that the cost incurred for traversing the at least one workflow process step, given the property of the processing environment, is limited to a cost threshold specified in a service level agreement (SLA) for a user requesting execution of the transaction.

8. The computer-implemented method of claim 7, wherein the cost threshold is specific to at least one of:

(i) the workflow process model and (ii) the at least one workflow process step.

9. A computer program product comprising:

a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code comprising;

computer-readable program code configured to provide a tool for editing a workflow process model comprising a plurality of workflow process steps, wherein the workflow process model is to be executed in a processing environment;

computer-readable program code configured to receive a request to assign a cost factor to at least one workflow process step of the plurality of workflow process steps, wherein the cost factor depends at least in part on a property of the processing environment at a time that the workflow process model is executed in the processing environment; and

computer-readable program code configured to assign the cost factor to the at least one workflow process step responsive to the request, such that a traversal of the at least one workflow process step by a transaction invoking the workflow process model results in the cost factor being included in a total cost to be charged for executing the transaction.

10. The computer program product of claim 9, wherein the property of the processing environment characterizes a degree of resource utilization in the processing environment.

11. The computer program product of claim 9, wherein the property of the processing environment comprises at least one of processor utilization, memory utilization, storage utilization, and network utilization in the processing environment.

12. The computer program product of claim 9, wherein the cost factor further depends on a property of the transaction.

13. The computer program product of claim 9, wherein the workflow process model further comprises branching logic comprising a precondition for traversing the at least one workflow process step.

14. The computer program product of claim 13, wherein the total cost to be charged for executing the transaction is a function of which specific one or more workflow process steps of the workflow process model are traversed in executing the transaction.

15. The computer program product of claim 13, wherein the precondition specifies that the cost incurred for traversing the at least one workflow process step, given the property of the processing environment, is limited to a cost threshold specified in a service level agreement (SLA) for a user requesting execution of the transaction.

16. The computer program product of claim 15, wherein the cost threshold is specific to at least one of:

(i) the workflow process model and (ii) the at least one workflow process step.

17. A system, comprising:

one or more computer processors; and
