Enabling Resource Assignment Constraints in BPMN

چکیده
Due to the critical role humans play in automated business processes, a BPEL extension has been recently released BPEL4People and WS-HumanTask to express issues like authorization to execute a task. However, there is currently little support to human resource allocation to tasks in high level modeling languages such as BPMN. In this paper, we show how resource allocation can be captured in BPMN. We extend the meta model to hold the information needed and we use Object Constraint Language (OCL) to express resource allocation constraints. Using OCL enables us to directly reflect the assignments and constraints on the model level in order to automatically propagate them to the execution. Thus, we benefit from a model driven approach in the area of business process management.

In this paper, a due date assignment scheduling problem with precedence constraints and controllable processing times in uncertain environment is investigated, in which the basic processing time of each job is assumed to be the symmetric trapezoidal fuzzy number, and the linear resource consumption function is used.The objective is to minimize the crisp possibilistic mean (or expected) value of...
متن کاملExtended Resource Perspective Support for BPMN and BPEL
This work provides support to the modeling and execution of the Resource Perspective of Business Processes with BPMN and BPEL. It is based on an extension developed to BPMN 2.0 in order to define and visualize the Resource Structure, Work Distribution and Authorization aspects of this perspective. This work proposes a mapping of extended BPMN process models to BPEL processes applying the BPEL4P...
متن کاملRAL: A High-Level User-Oriented Resource Assignment Language for Business Processes
An important task of business process design is the definition of what and how members of an organization are involved in the activities of the business processes developed within it. In this paper we analyse the capabilities of BPMN 2.0, the de-facto standard for business process modelling, in this regard. The conclusion is that, although it provides some mechanisms to assign resources to busi...
متن کاملA THEORETICALLY CORRECT RESOURCE USAGE VISUALIZATION FOR THE RESOURCE-CONSTRAINED PROJECT SCHEDULING PROBLEM
The cumulative resource constraints of the resource-constrained project scheduling problem (RCPSP) do not treat the resource demands as geometric rectangles, that is, activities are not necessarily assigned to the same resource units over their processing times. In spite of this fact, most papers on resource-constrained project scheduling mainly in the motivation phase use a strip packing of re...

Organizations need to manage the responsibility of their employees with respect to all the activities that are daily carried out within them. Process-oriented organizations need to do it, in addition, in accordance to the business processes their members participate in. However, powerful mechanisms to manage responsibility in combination with business processes are missing in current modelling ...
