Proposal for Using Semantic Technologies as a Means to Store and Exchange Subject-Oriented Process Models

This article re-investigates the idea of using the semantic-web-technologies for formally describing subject-oriented process models. It proposes improvements to previous knowledge models for subject-oriented process description and discusses why process models should directly be described in the web-ontology language, instead of only using it as secondary meta concept with the overall goal to enable interoperability between various S-BPM tools.

Automatic Tool Support Possibilities for the Text-Based S-BPM Process Modelling Methodology

In the sister paper to this work1 we proposed a method for using natural language text as the working basis of business process management efforts, especially incorporating the subject-oriented business process management and modeling (S-BPM) paradigm. The texts then would function as the basis to derive formal process models from. The methodology alone, especially when executed manually, may not have enough advantages over classical direct description-to-formal-model approaches. Consequently, in this paper we examine the possibilities, but also the limitations, of using state of the art computer linguistic tools to automate and support the derivation process.

Abstract Layers in PASS – A Concept Draft

In this paper we present a first draft for a concept of using abstract layers to extend the modeling capabilities of the subject-oriented graphical process-modeling language PASS. The concept is nonintrusive to existing PASS specification. It is argued how the Abstract Layered PASS (ALP) concept can be used to manage and integrate challenges and requirements found in subject-oriented and general process management research. Also a holistic discussion of similar or related approaches within and outside S-BPM is given.

Working with Natural Language Texts for Process Management: Proposal and Analysis of a Process Analysis Methodology

In this paper we present a method that describes what steps have to be performed in order to derive executable subject-oriented process models from natural language descriptions with the goal to simplify the information exchange between process practitioners and BPM experts. After laying down the necessary formal foundation and the proposed methodology itself, the methodology will be evaluted with a use-case scenario, taken from the area of energy management in electro mobility.

Using the arbitrator pattern for dynamic process-instance extension in a work-flow management system

This paper presents the idea of using the Arbitrator Pattern, a concept from the field of robotics, and applying it to the domain of business process model interpretation, using it as a mechanism to allow dynamic adaption and extension of process instances at runtime. The idea is discussed and a formal specification is given using ASMs to detail the concept that was derived in the process of exploring the problem so far. Furthermore the non-trivial questions and issues are raised that will need to be addressed for this just started work-inprogress to advance.

An Editing Concept for PASS Layers

In this paper we present a graphical editing concept to extend the capabilities of the subject-oriented process-modeling language PASS. The concept builds up on the arbitrator-pattern-inspired PASS-interpreter and clarifies its ad-hoc instance extension and exception handling mechanisms. The paper thereby proposes the arbitrator pattern as a possible alternative for the PASS guard mechanism.

Mapping PASS Graphs to Petri-Nets: Possibilities and Limits for Converting PASS Graphs to Petri-Nets

This paper presents a concept for mappings that can be applied to form a Petri-Net-Graph from the information of a business process model created with the Parallel Activity Specification Schema (PASS). Furthermore the possible uses as well as the shortcomings of this approach are discussed. In the appendix a formal specification for such a converter is given.

Sisi in the ALPS: A Simple Simulation and Verification Approach for PASS

Originally developed as a simple static computation tool (Simple Sim - SiSi), in this paper we describe the principle behind a pragmatic approach that is not only practical for simple calculation of lead times for process models in Abstract Layered PASS (ALPS), but also can serve as tool of structural soundness verification for the distributed and somewhat fractured descriptions of this subject-oriented process modeling language. It is the foundation for the first deployed tool that can handle soundness verification all of PASS including the multi-subject construct.

The Semantic Exchange Standard for Subject-Oriented Process Models

After the first general concept about using ontologies for the exchange of subject-oriented business process models in 2014, a concrete proposal for using the Web Ontology Language (OWL) and the semantic web technology framework as a concrete and direct means was made in 2017 including a proof of concept and proposal for a first standard. Based upon this work a standardization committee has formed and further developed the concept, brought in or reduced definitions, and discussed and agreed on specific controversial topics. In this paper we describe the progress made in 2017 and the current state of the OWL-Standard for the Subject-Oriented Parallel Activity Specification Schema (PASS) modeling language. We present the current state and argue for the made conventions.

Neue Wege durch Service Prototyping : Verbesserte Kommunikation und Entscheidungsfindung in der Dienstleistungsentwicklung durch den Einsatz von Prototyping

Kurzfassung Service Prototyping dient primär dazu, Dienstleistungen im Entwicklungsstadium erlebbar zu machen. Das Projekt dimenSion strebt somit an, ein praxisorientiertes Verfahren bereitzustellen, das auch von KMU mit einem guten Aufwand/Nutzen-Verhältnis eingesetzt werden kann und den Erfolg entwickelter Dienstleistungen absichert. Durch den Einsatz von Service Prototyping sollen Unternehmen dabei unterstützt werden, ihre Entscheidungsfindung zu verbessern und Alternativen besser bewerten zu können.
