The document discusses using complex event processing (CEP) to enable dynamic adaptation of business processes. It presents the CEVICHE framework, which integrates CEP into business process execution using plug-ins. CEVICHE consists of a user interface to create process definitions, plug-ins for different CEP engines, and an aspect manager to handle process adaptation. The framework facilitates CEP integration and allows non-static, dynamically adaptable processes without dependencies on specific CEP engines. An example of an online car rental process is provided to illustrate how CEP could maintain quality of service through optional task exclusion.

3. Introduction
• The Objectives in the paper are :
 To show why dynamic adaptation is needed in today’s business processes.
 To integrate CEP into business process to help in the decision making task
 To provide a framework that facilitates such integration by giving the users
a unique entry point to create dynamically adaptable business processes .

4. Motivation and Challenges
 Motivation
1. To show how CEP and CEVICHE can be used to maintain a high QoS.
2. We will present an on-line car rental service .
3. In this service , the client goes through a process of eleven steps to get car .

5. Motivation and Challenges

6. Motivation and Challenges
The client starts the
process by providing a valid license number,

7. Motivation and Challenges
The optional tasks that could be excluded from the business process of this scen
ario, without altering the main objective, are: the color select (step c) and the satisfa
ction survey (step j)

8. Motivation and Challenges
 Challenges
1. Lack of specification in the BPEL (Business Process Execution Language) to monitor
the business processes .
2. Adding a lot of unnecessary code to the core business process definition .
3. The business process definitions are static

9. Backgrounds
 Complex Event Processing
 CEP is an emerging technology for finding relationships be
tween series of simple and independent events from depen
dent source , using defined rules
 Example :
 ERP System

11. Backgrounds
 Business Process Execution Language
 BPEL is an XML-based language for composing service .
 It uses web services as a way to communicate with the different parties inv
olved in the business process .

13. CEVICHE Framework
 CEVICHE Architecture
- CEVICHE is composed of three main parts :
1. A User Interface to create the SBPL files
2. The plug –ins for each CEP engine
3. An aspect manager to deal with the process adaptation

14. A User Interface to create the SBPL files

15. The plug –ins for each CEP engine

16. An aspect manager to deal with the process adaptation

17. Conclusion
• To facilitate the integration of CEP into existing business
• CEVICHE
 Adaptation
 Dynamicity
 Integrate to business process
 Non-dependency to a specific
