Since the early nineties business processes have been coming more and more into the focus of IS research. As a consequence numerous approaches to process modelling have been developed such as Event-driven Process Chains (EPCs, ARIS House of Business), Semantic Object Model (SOM), Bonapart and INCOME/STAR. Many of these approaches concentrate on the socio-technical dimension of business processe...

Event-Driven Process Chains (EPC) is a business process modeling language developed in a joint effort between SAP and the Institute of Information Systems of Saarbrücken in the context of the Architecture of Integrated Information Systems (ARIS) framework (Keller, Scheer, & Nüttgens, 1992). One of the initial purposes of EPC was to configure workflows in ERP software such as SAP R/3. As the lan...

This paper reports on ongoing work towards a framework to automatically rewrite business process models and, thereby, correctively enforce adherence to regulatory compliance and security policies. Specifically, the paper first motivates the need for rewriting mechanisms as a means to enforce a particular class of properties. Second, it describes the main building blocks of ReWrite, the framewor...

In this paper we propose new methods for ordering the Web pages returned from search engines. Given a few search keywords, nowadays most search engines could retrieve more than a few thousand Web pages. The problem is how to order the retrieved Web pages and then to present the most relevant Web pages first. We propose new factors to allow relevant Web pages to be ranked higher. The factors inc...

Abstract The production of hybrid components involves a long process chain, which leads to high investment costs even before machining. To increase safety and quality during finishing, it is necessary provide information about the semi-finished parts geometry for machining identify defect at an early stage. This paper presents investigation predict variations in dimension cavities inside materi...

Almost no construction project performs totally as planned as dynamic changes are frequently needed. These changes can be ascribed to the high uncertainty, which is evaluated as potential causes of risks and risks is in turn are evaluated as potential causes of plan changes. Several concepts from the Business Process Modeling domain are adopted to build an explicit processoriented knowledge doc...

Process mining techniques enable the analysis of processes using event data. For structured processes without too many variations, it is possible to show a relative simple model and project performance and conformance information on it. However, if there are multiple classes of cases exhibiting markedly different behaviors, then the overall process will be too complex to interpret. Moreover, it...

The formalization of process definitions has been an invaluable aid in many domains. However, noticeable variations in processes start to emerge as precise details are added to process definitions. While each such variation gives rise to a different process, these processes might more usefully be considered as variants of each other, rather than completely different processes. This paper propos...

In the present work, we consider spectrally positive Lévy processes (Xt, t ≥ 0) not drifting to +∞ and we are interested in conditioning these processes to reach arbitrarily large heights (in the sense of the height process associated with X) before hitting 0. This way we obtain a new conditioning of Lévy processes to stay positive. The (honest) law Px of this conditioned process is defined as ...
