10th International Workshop on DEClarative, DECision and Hybrid approaches to processes (DEC2H 2022) In conjunction with BPM 2022

Workshop: , Münster, Germany

About DEC2H

Workshop Theme

Rules and decisions define the behavioural constraints and factors determining the achievement of process goals. Business processes frequently involve rule-bound decisions – particularly knowledge-intensive processes, which operate in highly variable contexts and are thus flexible by nature. When describing such processes, variability and flexibility call for explicit statements of the underlying rules and decisions.
While traditional notations such as BPMN excel at describing “happy paths”, they may fall short when modelling flexible and varying rules and decisions, wherein procedural models tend to clutter and become imprecise or impractical. Declarative modelling paradigms (such as Declare, DCR Graphs, DMN, CMMN, GSM, and DPIL) aim to directly capture the business rules or constraints underlying the process and thus tackle this challenge. A promising direction is the hybridisation of procedural and declarative approaches.

In this workshop, we are interested in the application and challenges of decision- and rule-based modelling in all phases of the BPM lifecycle: identification, discovery, analysis, redesign, implementation and monitoring. Contributions are welcome that adopt existing formalisms or introduce novel ones, in the form of completed work (research, case studies and tools) but also work-in-progress and position papers.

Purpose of the workshop

The purpose of the workshop is:

  • to examine the relationship between rules, decisions and processes, including models; not only to model the process, but also to model the rules and decisions;
  • to enhance rule and decision mining based on process data (e.g., event logs);
  • to examine decision goals, structures, and their connection with business processes, in order to find a good integration between rule- and decision-based modelling and flow-based modelling;
  • to examine standards (DMN, CMMN, BPMN) and their integration;
  • to study how different process models can be designed to fit a decision process, according to various optimization criteria, such as throughput time, use of resources, etc.;
  • to study the integration between declarative models with traditional imperative models;
  • to show best practices in separating process, rule and decision concerns.


Topics of interest include, but are not limited to:

Declarative and hybrid (process modelling) approaches

  • Declarative notations (Declare, DCR, GSM, eCRG, DPIL, …)
  • Decision & goal notations (DMN, PDM, …)
  • Case management notations (CMMN, fCM, …)
  • Declarative and hybrid modelling methodologies
  • Process metrics
  • Process maintenance and flexibility
  • Human-centered and flexible processes
  • Decision rules and processes
  • Decision models and structures
  • Formal analysis (e.g., expressiveness proofs) of declarative and hybrid notations
  • Formal verification (e.g. model-checking and static analysis) of declarative and hybrid models
  • Run-time adaptation of declarative and hybrid process models

Decision mining and declarative/hybrid process mining

  • Decision mining
  • Declarative process mining
  • Hybrid process mining
  • Data mining for decision and declarative/hybrid process analysis
  • Rule mining for decision and declarative/hybrid process analysis

Applications of decision- and rule-modelling in BPM

  • Goal-driven processes
  • Knowledge-intensive processes
  • Business process compliance
  • Knowledge workflow management
  • Usability and understandability studies
  • Case studies
  • Tools

Paper submission

Submission guidelines

Prospective authors are invited to submit papers on any of the topics of the workshop. We are interested in research, work-in-progress, case-study and tool papers, either in long (not exceeding 12 pages) or short (not exceeding 6 pages) format, or position / vision papers in a short format.

  • Research and work-in-progress papers describe original research work in the broad area of declarative, decision and hybrid approaches to processes. Such papers can report on complete technical work or early results that reveal promising but require more work to get to full maturity.
  • Short position or vision papers (not exceeding 6 pages) discuss a novel problem or idea related to the topics of the workshop and can be used as an opportunity to foster discussion at the event and reach out to interested collaborators. Accepted papers will use a special presentation format at the workshop, with a shorter presentation but more room for discussion. Papers in this category will be evaluated with a focus on their novelty and potential to foster an engaged discussion at the workshop.
  • Case-study papers report on case-studies and industrial applications of declarative, decision and hybrid approaches to processes. Papers in this category are expected to clearly describe the case being studied, the methodologies used, and their implications for relevant research problems.
  • Tool papers describe novel tools supporting declarative, decision and hybrid approaches to processes. Papers in this category will be evaluated based on the novelty and maturity of the tools presented and authors are expected to include artefacts such as links to a demo version of the tool and video tutorials.

The final selection of papers will consider all categories equally, with each paper reviewed according to the expectations for their category.

Only papers in English will be considered. Submitted papers must present original research contributions not concurrently submitted elsewhere. Authors are requested to prepare submissions according to the Lecture Notes in Business Information Processing (LNBIP) format specified by Springer (see the instructions). The title page must contain a short abstract and a list of keywords, preferably using the list of topics given above.

Papers must be submitted electronically via EasyChair: enter the main conference installation (BPM 2022) at and select 10th International Workshop on DEClarative, DECision and Hybrid approaches to processes as the submission track.

Paolo Ceravolo: The Quest for Conflicting Knowledge. How to stay sane while data gets messed up.


We typically learn that science proceeds from observation to theory, from facts to the definition of models. But this does not hold in design science where observations of the artifact or the systems can bring the designer to change both the system or its goals. Similarly, when comparing the expected or observed behavior of a process the designer is in front of an epistemic dilemma. Should we change the specification of the system or modify the way we are enforcing its behavior? Decision- and rule-based modeling is particularly affected by conflicting knowledge. If fewer customers than expected are selecting credit card payments is it because of an error in the way we designed the user interface or it is because new payment channels are emerging? If cycle time efficiency is lower in the morning is it because of the resources engaged, the activities executed, or other invisible factors influencing the production during its initialization? In design science, or simply in science, conflicting knowledge is not an accident nor an annoyance but a great opportunity to uplift knowledge. We simply need the patience for comprehension, studying the roots of these conflicts and the way to turn them into action-oriented behavior.

The workshop begins with a keynote, followed by presentations of accepted papers. Full papers have 20 minutes for their presentations plus 10 minutes for discussion and Q&A. Short papers have 15 plus 5 minutes at their disposal.

Each manuscript will be reviewed by at least three program committee members guaranteeing that only papers presenting high quality work and innovative research in areas relevant to the workshop theme are accepted. Papers that are not accepted, yet reviewed positively, may still be invited for presentation at the workshop.

Accepted papers will appear in the workshop proceedings. The pre-prints will be made available before the workshop starts. The post-proceedings will be published by Springer in the Lecture Notes in Business Information Processing (LNBIP) series, in a single volume dedicated to the proceedings of all BPM 2022 workshops. During a time window after the conference, the workshop participants are granted the free download of the papers.

At least one author of each accepted manuscript is required to register for the workshop and present the paper. Registration is subject to the terms, conditions and procedures of the main BPM 2022 conference to be found on its website.
