Conformance checking and diagnosis for declarative business process models in data-aware scenarios
A business process (BP) consists of a set of activities which are performed in coordination in an organizational
and technical environment and which jointly realize a business goal. In such context, BP management
(BPM) can be seen as supporting BPs using methods, techniques, and software in order to design,
enact, control, and analyze operational processes involving humans, organizations, applications, and
other sources of information. Since the accurate management of BPs is receiving increasing attention,
conformance checking, i.e., verifying whether the observed behavior matches a modelled behavior, is
becoming more and more critical. Moreover, declarative languages are more frequently used to provide
an increased flexibility. However, whereas there exist solid conformance checking techniques for imperative
models, little work has been conducted for declarative models. Furthermore, only control-flow perspective
is usually considered although other perspectives (e.g., data) are crucial. In addition, most
approaches exclusively check the conformance without providing any related diagnostics. To enhance
the accurate management of flexible BPs, this work presents a constraint-based approach for conformance
checking over declarative BP models (including both control-flow and data perspectives). In addition,
two constraint-based proposals for providing related diagnosis are detailed. To demonstrate both
the effectiveness and the efficiency of the proposed approaches, the analysis of different performance
measures related to a wide diversified set of test models of varying complexity has been performed.Ministerio de Ciencia e Innovación TIN2009-1371
Conformance Checking Based on Multi-Perspective Declarative Process Models
Process mining is a family of techniques that aim at analyzing business
process execution data recorded in event logs. Conformance checking is a branch
of this discipline embracing approaches for verifying whether the behavior of a
process, as recorded in a log, is in line with some expected behaviors provided
in the form of a process model. The majority of these approaches require the
input process model to be procedural (e.g., a Petri net). However, in turbulent
environments, characterized by high variability, the process behavior is less
stable and predictable. In these environments, procedural process models are
less suitable to describe a business process. Declarative specifications,
working in an open world assumption, allow the modeler to express several
possible execution paths as a compact set of constraints. Any process execution
that does not contradict these constraints is allowed. One of the open
challenges in the context of conformance checking with declarative models is
the capability of supporting multi-perspective specifications. In this paper,
we close this gap by providing a framework for conformance checking based on
MP-Declare, a multi-perspective version of the declarative process modeling
language Declare. The approach has been implemented in the process mining tool
ProM and has been experimented in three real life case studies
IUPC: Identification and Unification of Process Constraints
Business Process Compliance (BPC) has gained significant momentum in research
and practice during the last years. Although many approaches address BPC, they
mostly assume the existence of some kind of unified base of process constraints
and focus on their verification over the business processes. However, it
remains unclear how such an inte- grated process constraint base can be built
up, even though this con- stitutes the essential prerequisite for all further
compliance checks. In addition, the heterogeneity of process constraints has
been neglected so far. Without identification and separation of process
constraints from domain rules as well as unification of process constraints,
the success- ful IT support of BPC will not be possible. In this technical
report we introduce a unified representation framework that enables the
identifica- tion of process constraints from domain rules and their later
unification within a process constraint base. Separating process constraints
from domain rules can lead to significant reduction of compliance checking
effort. Unification enables consistency checks and optimizations as well as
maintenance and evolution of the constraint base on the other side.Comment: 13 pages, 4 figures, technical repor
XRound : A reversible template language and its application in model-based security analysis
Successful analysis of the models used in Model-Driven Development requires the ability to synthesise the results of analysis and automatically integrate these results with the models themselves. This paper presents a reversible template language called XRound which supports round-trip transformations between models and the logic used to encode system properties. A template processor that supports the language is described, and the use of the template language is illustrated by its application in an analysis workbench, designed to support analysis of security properties of UML and MOF-based models. As a result of using reversible templates, it is possible to seamlessly and automatically integrate the results of a security analysis with a model. (C) 2008 Elsevier B.V. All rights reserved
Clinical Processes - The Killer Application for Constraint-Based Process Interactions?
For more than a decade, the interest in aligning information
systems in a process-oriented way has been increasing. To enable operational
support for business processes, the latter are usually specified in
an imperative way. The resulting process models, however, tend to be too
rigid to meet the flexibility demands of the actors involved. Declarative
process modeling languages, in turn, provide a promising alternative in
scenarios in which a high level of flexibility is demanded. In the scientific
literature, declarative languages have been used for modeling rather simple
processes or synthetic examples. However, to the best of our knowledge,
they have not been used to model complex, real-world scenarios
that comprise constraints going beyond control-flow. In this paper, we
propose the use of a declarative language for modeling a sophisticated
healthcare process scenario from the real world. The scenario is subject to
complex temporal constraints and entails the need for coordinating the
constraint-based interactions among the processes related to a patient
treatment process. As demonstrated in this work, the selected real process
scenario can be suitably modeled through a declarative approach.Ministerio de EconomÃa y Competitividad TIN2016-76956-C3-2-RMinisterio de EconomÃa y Competitividad TIN2015-71938-RED
What Automated Planning Can Do for Business Process Management
Business Process Management (BPM) is a central element of today organizations. Despite over the years its main focus has been the support of processes in highly controlled domains, nowadays many domains of interest to the BPM community are characterized by ever-changing requirements, unpredictable environments and increasing amounts of data that influence the execution of process instances. Under such dynamic conditions, BPM systems must increase their level of automation to provide the reactivity and flexibility necessary for process management. On the other hand, the Artificial Intelligence (AI) community has concentrated its efforts on investigating dynamic domains that involve active control of computational entities and physical devices (e.g., robots, software agents, etc.). In this context, Automated Planning, which is one of the oldest areas in AI, is conceived as a model-based approach to synthesize autonomous behaviours in automated way from a model. In this paper, we discuss how automated planning techniques can be leveraged to enable new levels of automation and support for business processing, and we show some concrete examples of their successful application to the different stages of the BPM life cycle
