“…Workflows which can be adapted automatically or semi-automatically according to context information are defined as "Smart Workflows" (Wieland, Nicklas, & Leymann, 2008). Smart Workflow concept is referred to in different ways by some other studies, such as "Person-centric Flow" (Unger, Eberle, Leymann, & Wagner, 2010), "Adaptable Pervasive Flow" (Wolf, Herrmann, & Rothermel, 2009), and "Situated Flow" . Even though the names used are different, the concepts are similar.…”

In this thesis study, a framework offering people help and guidance for organizing their daily activities is proposed. This framework allows users to model their daily activities in the form of workflows. Due to the dynamic nature of pervasive environments, workflows are enabled to be adaptable at runtime according to context information collected in pervasive environments. A workflow engine is used for modeling and management of workflows and a separate rule engine with Complex Event Processing (CEP) capability is incorporated into the framework for both enhancing workflow adaptation and execution and for rule-based context reasoning. The adaptation model in the framework allows modeling activities in a hierarchical manner, from high level abstract activities to more detailed ones. Event-driven Architecture (EDA) is utilized for loosely coupled interaction between the workflow engine and the rule engine, allowing these engines, other context sources and userlevel applications to exchange data among each other. Since workflow engines are sufficiently complex, EDA allows incorporation of context information into the workflow models without modifying the workflow language. A higher automation level than the level supported by workflows is proposed by processing events in pervasive environments using CEP. A prototype implementation is developed and the framework is evaluated with some real life examples and experimental tests demonstrating its applicability.

“…As the project coordinator, Prof. Frank Leymann and his team play an important role and extend the research area of context-aware workflow to the manufacturing environment (Cipriani et al, 2011; Wieland et al, 2007). They use context-aware workflows for failure management in a smart factory (Wieland et al, 2010) and also utilize the context model for representation of business process management artifacts (Wieland et al, 2011) and developed some algorithms to improve the systems (Rothermel et al, 2012; Wolf et al, 2009).…”

The variety of product types/specifications in discrete manufacturing enterprises makes new product development tasks real tough work. Therefore, it is a common strategy for workers to refer to similar outcomes (e.g. the product drawings and work instructions) of former new product development tasks. In order to discover similar historic outcome, this article presents an intelligent approach to measure the cohesion between workflow contexts in process-aware information systems and exploit it for runtime task knowledge recommendation. The measure of context similarity is preceded by (1) modeling the task context with ontology theory and (2) using the ontology matching algorithms to evaluate the similarities between context ontology entities of different tasks. Specifically, the term frequency–inverse document frequency approach is utilized to compute the context cohesion between current task and historic ones, and the tasks with the highest similarity will be recommended to the task executors, along with their outcomes. Comparative evaluation is performed using term frequency–inverse document frequency, Levenshtein, and Affine Gaps, and results demonstrate that the proposed approach achieves good precision and recall and is efficient in task knowledge recommendation.

These models describe the control flow, dataflow and the service calls in the workflow as well as the usage of context-data in the workflow.…”

Abstract-Context-aware systems adapt their functionality and behavior to the user and his or her situation. To do so, they need context information about the user's environment, e.g., about different kinds of real world objects. Many systems and data models are available for the management of context information. An often neglected but important part of context is the state and context of the applications that users are currently executing. This paper presents the benefits of using the context of workflow-based applications in the area of human task management. We show what kind of new task clients for mobile users are enabled by a context model for business process management and present an implementation of the system.
