abstract = {Management of business processes is typically performed on multiple levels,
each with different granularity, language constructs, and abstraction. Starting
from an initial sketch of the activities to be performed, several refinements
are made to entirely specify the business process, its artifacts, and
participants. Then, information relevant for process execution can be added to
enable efficient automation in the context of a service-oriented architecture
(SOA). However, dealing with changes initiated by business or technology is a
key difficulty in this approach. If change management is not performed properly
then process models become out of sync which results in losing the alignment of
business and IT. To address this challenge, we propose a synchronization method
based on model element correspondence that considers change management between
process models on different abstraction levels. We show how synchronization can
be established and changes are propagated using a change queue for
synchronization continuity. Finally we present a prototypical implementation of
the key concepts.},

abstract = {In recent years scientific workflows have been used for conducting
data-intensive and long running simulations. Such simulation workflows have
processed and produced different types of data whose quality has a strong
influence on the final outcome of simulations. Therefore being able to monitor
and analyze quality of this data during workflow execution is of paramount
importance, as detection of quality problems will enable us to control the
execution of simulations efficiently. Unfortunately, existing scientific
workflow execution systems do not support the monitoring and analysis of
quality of data for multi-scale or multi-domain simulations. In this paper, we
examine how quality of data can be comprehensively measured within workflows
and how the measured quality can be used to control and adapt running
workflows. We present a quality of data measurement process and describe a
quality of data monitoring and analysis framework that integrates this
measurement process into a workflow management system.},

abstract = {The number of applications and services hosted in the cloud grows steadily,
because of significant advantages in cost, flexibility, and scale compared to
traditional IT. However, major difficulties in this field are (i) the migration
of existing applications into the cloud and (ii) the increasing vendor lock-in
which denotes the inability to leave a certain cloud provider without
significant effort. Current approaches do not offer a holistic solution: Either
they require the user to provide the application in a certain standardized way
or they are only able to migrate one specific type of component. As a
consequence, the migration of composite applications with different types of
components is not supported. To overcome this limitation we propose the Cloud
Motion Framework (CMotion) which leverages existing application models and
provides support to migrate composite applications into and between clouds.
Based on the application model, the framework evaluates alternative ways to
host each component. CMotion assumes that the dependencies of components are
modeled explicitly and the components are self-contained.},

more attraction for enterprises today. Many enterprises are on the gap of
installing workflow systems within their premises. During this process they
need to make sure that several regulations, coming from governments or
enterprise-internal institutions, are obeyed. We argue that the compliance
regulations, enterprises are faced with today, can be built using a number of
atomic compliance requirements. We studied literature and identified new atomic
requirements in our work with industrial use case partners taking part in
research projects founded by the European Union, as well as projects with
customers that face the same challenges. The atomic compliance rules, we
identified, can be divided into two groups, data-related and
control-flow-related compliance rules. The main contribution of this paper is a
collection of patterns implementing complex compliance rules which consist of
atomic control-flow related and data-related compliance rules. We show how
these atomic rules must be applied to a business process in order to implement
the desired behaviour, intended by a complex compliance rule. We extended an
existing collection of recurring atomic compliance rules with a new set of
data-related compliance rules. These compliance rules contain variabilities
which need to be filled when they are applied to a business process model.},

increasing adoption of Business Process Management (BPM) in organizations,
efforts are being made to also enable a green rethinking and change of BPM.
However, in order to be capable of performing business in a green manner, the
“delta” has to be known that distinguishes green business process management
from the conventional one. In this paper, we investigate key perspectives of
conventional BPM and compare them to requirements originating from an
environmental perspective. The key perspectives we refer to are the business
process lifecycle, key performance indicators, BPM architectures, and business
and strategy. We highlight aspects that need to be extended, newly developed,
or refined in order to achieve a holistic green BPM approach.},

abstract = {Cloud computing has drastically changed the way in which IT resources can be
consumed. The properties of clouds – elasticity, pay-per-use, and
standardization of the runtime infrastructure – enable cloud providers and

reduced runtime costs. However, to achieve these benefits, application
architects and developers have to respect the characteristics of the cloud
environment. To reduce the complexity of cloud application architecture and
design, we propose a pattern-based approach for cloud application architecture
and development. We defined a pattern format to describe the principles of
cloud computing, available cloud offerings, and cloud application
architectures. Based on this format we developed an architectural pattern
language of cloud-based applications. Through interrelation of patterns for
cloud offering descriptions and cloud application architectures, developers are
guided during the identification of patterns applicable to their problems. We
cover the proceeding how we identified patterns, give an overview of previously
discovered patterns, and introduce one new pattern. Further, we propose a
framework for the organizations of patterns and the guidance of developers
during their instantiation.},

the art in the workflow technology, the latter is currently insufficiently
addressed in literature and practice. We argue that a manually triggered rerun
operation enables both business users and scientists to react to unforeseen
problems and thus improves workflow robustness, allows scientists steering the
convergence of scientific results, and facilitates an explorative workflow
development as required in scientific workflows. In this paper, we therefore
formalize operations for the repeated enactment of activities—for both
iteration and re-execution. Starting point of the rerun is an arbitrary,
manually selected activity. Since we define the operations on a meta-model
level, they can be implemented for different workflow languages and engines.},

developed without adhering to known software engineering guidelines, lack an
acceptable software ergonomics, run sequentially on single workstations and
require tedious manual tasks. We are convinced that SOA concepts and the
service composition technology can help to improve this situation. In this
paper we report on the results of our work on the service- and service
composition-based re-engineering of a legacy scientific application for the
simulation of the ageing process in copper-alloyed. The underlying general

abstract = {BPEL’n’Aspects is a non-intrusive mechanism for adaptation of control flow of
BPEL processes based on the AOP paradigm. It relies on Web service standards to
weave process activities in terms of aspects into BPEL processes. This paper is
a logical continuation of the BPEL’n’Aspects approach. Its main objective is to
enable compensation of weaved-in Web service invocations (activities) in a
straightforward manner. We present (1) requirements on a mechanism for
compensation of weaved-in process activities; (2) the corresponding concepts
and mechanisms to meet these requirements; (3) an example scenario to show the
applicability of the approach; and (4) a prototypical implementation to prove
the feasibility of the solution. This work represents an improvement in the
applicability of this particular adaptation approach since processes in
production need the means to compensate actions that are included into
processes as result of an adaptation step, too. The concept is generic and
hence can also be used by other approaches that adapt control flow.},

they provide to scientists in computer simulations, experiments and
calculations. Our experiences with workflows in this field and the literature
show that scientific workflows consist of a large number of related
information. This information is difficult to deal with in a single perspective
and has changing importance to scientists in the different workflow lifecycle
phases. In this paper we apply viewing techniques known from business process
management to (service-based) scientific workflows to address these issues. We
describe seven of the most relevant views and point out realization challenges.
We argue that the selected views facilitate the handling of workflows to
scientists and add further value to scientific workflow systems. An
implementation of a subset of the views based on Web services and BPEL shows
the feasibility of the approach. The presented work has the goal to increase
additionally the acceptance of the workflow technology in e-Science.},

service-based communication interfaces between enterprise and manufacturing
systems. Constantly changing business conditions demand a high level of
flexibility in business processes as well as an adaptive and fully
interoperable IT infrastructure. The principles of reusability and
loosely-coupled services have driven Service Oriented Architecture (SOA) to
become the most used paradigm for software design at the business level. In a
manufacturing environment, event-driven architectures (EDA) are often employed
for managing information flows across different production systems. The timely
propagation of business-relevant events is a fundamental requirement in
Engineer-to-Order (ETO) enterprises, which require a high level of transparency
in their supply chains. Agility is one of the top priorities for ETO
manufacturers in order to react to turbulent scenarios. Therefore, the main
challenge for ETO supply chains is to identify and propagate events across the
ETO logistics network and integrate these into the manufacturer business
processes. We present how an existing service-oriented integration platform for
manufacturing can be used to fill the gap between EDA-based manufacturing
environments of an ETO supply chain and SOA-based manufacturer business
processes. In this paper, we discuss the benefits of the Business Process
Execution Language (BPEL) as vehicle for this integration. The adoption of BPEL
will enable an efficient and effective reaction to turbulent manufacturing
scenarios in an ETO supply chain.},

tools for designing, analyzing, and executing their business processes. The
need for adapting processes to new requirements, to reuse parts of processes,

changes on multiple process models of different granularity and level of
abstraction. These changes cause a need for process models on different
abstraction levels to be synchronized in order to avoid inconsistencies. To
bridge the resulting Business IT gap, we introduce an approach which supports
the creation and adaptation of business processes on different abstraction
levels based on reusable process building blocks. The advantage of the approach
is that changes of the process can be driven by IT and Business in the same
manner, though on different levels of abstraction. In addition to the
methodology for this approach, we define reusable process building blocks,
describe sychronization mechanisms, and propose a supporting infrastructure. We
show the application of these concepts in a real world case study.},

networks for the exchanging of goods and services. Service networks models
represent the interconnections among companies, their parts and individuals in

representation of these interconnections. Due to the size of nowadays service
networks, their models tend to grow very large. The effective management of
service network models requires methods to limit the amount of data presented
on the basis of what is needed. This paper identifies a hierarchy of views on
service network models, namely offering-centric views, participant views and
multilateral views. The offering-centric views focus on one service that is
offered by one participant. Participant views present the entirety of the data
related to one participant. Multilateral views represent the data regarding a
set of participants. We identify the correlations between these views and the
mechanisms to aggregate and project them from each other and from service
network models. The concepts and mechanisms represented in this paper are
explained on a running example based on the automotive industry.},

face considerable fines when violating laws and regulation in their business

emerged. Datasovereignty is one of the major compliance concerns enterprises
have to deal with when moving applications and data to the cloud. Enterprises
are fully responsible for their data, also when the data is not present within
their IT premises anymore. This lead to the policy that specific data must not
leave the IT premises of the enterprise. In this paper we present an approach
to support the human process designer in modelling compliant business
processes. We are focusing on compliance requirements which have to be
considered in the field of cloud computing. These requirements have been
created to meet laws and regulations. These laws and regulations are
considering data which is sent around between countries, for example.
Considering the characteristics of these requirements, we deal with
data-centric compliance rules here.},

as Java code. However, current approaches for graphical monitoring of business
processes are limited to scenarios in which the process that is being executed
and the process that is being monitored are either one and the same or on the
same level of abstraction. In this paper, we present an approach to facilitate
business-oriented process monitoring while considering process design on
high-level. We propose process views for business process monitoring as
projections of activities and execution states in order to support business
process monitoring of running process instances on different levels of
abstraction. In particular, we discuss state propagation patterns which can be
applied to define advanced monitoring solutions for arbitrary graph-based
process languages.},

abstract = {Workflow evolution is a collective term for concepts that deal with changes of
workflow models. Adapted workflow models are deployed on a workflow engine as
new model version. That means two versions of the same model are deployed on
the engine. Typically, this results in conflicts between the workflow models.
For example, how does a client find and choose the desired workflow version to
instantiate? Typically, these problems are solved by deactivating the old
model. New instances can only be created for the new model. In our work on
scientific workflows we recognized that there are cases where it is desired to
keep the old model activated. In this paper we investigate what it means to
have several model versions active. We develop a general concept for this
“concurrent workflow evolution” that solves emerging problems. Moreover, we
show how this concept can be realized with BPEL.},

abstract = {Adequate data management and data provisioning are among the most important
topics to cope with the information explosion intrinsically associated with
simulation applications. Today, data exchange with and between simulation
applications is mainly accomplished in a file-style manner. These files show
proprietary formats and have to be transformed according to the specific needs
of simulation applications. Lots of effort has to be spent to find appropriate
data sources and to specify and implement data transformations. In this paper,
we present SIMPL – an extensible framework that provides a generic and
consolidated abstraction for data management and data provisioning in
simulation workflows. We introduce extensions to workflow languages and show
how they are used to model the data provisioning for simulation workflows based
on data management patterns. Furthermore, we show how the framework supports a
uniform access to arbitrary external data in such workflows. This removes the
burden from engineers and scientists to specify low-level details of data
management for their simulation applications and thus boosts their
productivity.},
