TL;DR: This paper describes a novel approach that identifies partial process models by exploiting sequential pattern mining and uses the additional information about the activities matching a partial process model to train nested prediction models from event logs.
Abstract: Process mining is a research discipline that aims to discover, monitor and improve real processing using event logs. In this paper we describe a novel approach that (i) identifies partial process models by exploiting sequential pattern mining and (ii) uses the additional information about the activities matching a partial process model to train nested prediction models from event logs. Models can be used to predict the next activity and completion time of a new (running) process instance. We compare our approach with a model based on Transition Systems implemented in the ProM5 Suite and show that the attributes in the event log can improve the accuracy of the model without decreasing performances. The experimental results show how our algorithm improves of a large margin ProM5 in predicting the completion time of a process, while it presents competitive results for next activity prediction.

TL;DR: This paper identifies important classes of properties on artifact-centric operational models, and proposes a formal model that guarantees persistence and uniqueness and proves that, while checking an arrival property is undecidable in general, under a restricted version of the formalism, an arrivalproperty can be checked in EXPTIME.
Abstract: Business artifacts are the core entities used by businesses to record information pertinent to their operations. Business operational models are representations of the processing of business artifacts. Traditional process modeling approaches focus on the actions taken to achieve a certain goal (verb-centric). Business artifact-centric modeling starts by identifying what is acted upon (noun-centric), and constructs business operational models by identifying the tasks/actions that business actors execute to add business value. In this paper, we identify important classes of properties on artifact-centric operational models. In particular, we focus on persistence, uniqueness and arrival properties. To enable a static analysis of these properties, we propose a formal model for artifact-centric operational models. We show that the formal model guarantees persistence and uniqueness. We prove that, while checking an arrival property is undecidable in general, under a restricted version of the formalism, an arrival property can be checked in EXPTIME.

TL;DR: The proposed uBPMN not only allows for modeling ubiquitous business processes but also lays the groundwork for potentially deploying a variety of ubiquitous computing technologies.
Abstract: Context: Business Process Model and Notation (BPMN) is the de facto standard for business process modeling. It was developed by the Object Management Group with support of the major organizations in the fields of software engineering and information systems. Despite its wide use, when it comes to representing ubiquitous business processes, this business process modeling language is lacking. Objective: To address BPMN’s deficiency in representing ubiquitous business processes, we extend it and present uBPMN (or ubiquitous BPMN). Method: First, we analyze the modeling requirements for representing ubiquitous business processes. Based on the requirements, we conservatively extend the Meta-Object Facility meta-model and the XML Schema Definition of BPMN as well as extend the notation. The extension, that we call uBPMN follows the same outline as set by the Object Management Group for BPMN. Results: The proposed uBPMN not only allows for modeling ubiquitous business processes but also lays the groundwork for potentially deploying a variety of ubiquitous computing technologies. We illustrate all of uBPMN’s capabilities and benefits with real-life examples. Conclusion: uBPMN extends BPMN v2.0 with new capabilities to deal with ubiquitous computing technologies.

TL;DR: A methodology for environmental impact minimization (MEIM) is presented in this paper, which embeds Life Cycle Analysis principles within a process optimization framework, involves proper definition of a consistent boundary around the process of interest, identification of the emissions inventory, quantification of environmental impact via proper metries, and inclusion of environmental criteria within process modelling and optimization tools.
