Modeling Business Process Variability

This master thesis presents research findings on business process variability modeling. Its main goal is to analyze inherent problems of business process variability and solve them simply, innovatively and effectively. To achieve this goal, process variability is defined by analyzing scientific literature, its main problems identified and is illustrated using a healthcare running example: process variability is classified into process variability within the domain space and over time. These two forms of process variability respectively lead to process variability modeling and process model evolution problems. After defining the main problems inherent to process variability, the focus of this research project is defined: solving process variability modeling problems. First current business process modeling languages are evaluated to assess the effectiveness of their respective modeling concepts when modeling process variability, using a newly created set of evaluation criteria and the healthcare running example. The following business process modeling languages are evaluated: Event driven process chains (EPC), the Business Process Modeling Notation (BPMN) and Configurable EPC (C-EPC). Business process variability modeling and Software product line engineering have similar problems. Therefore the variability modeling concepts developed by software product line engineering are analyzed. Feature diagrams and software configuration management are the main variability management concepts provided by software product line engineering. To apply these variability management concepts to model process variability meant combining them with existing business modeling languages. Riebisch feature diagrams are combined with C-EPC to form Feature-EPC. Applying software configuration management, meant merging Change Oriented Versioning with basic EPC to create COV-EPC, and merging the Proteus Configuration Language with basic EPC to design PCL-EPC. Finally these newly created business process modeling languages are also evaluated using the newly designed evaluation criteria and the healthcare running example. EPC or BPMN are not suited to model business process variability within the domain space. C-EPC provide explicit means to model business process variability, however the process models tend to get big very fast. Furthermore the syntax, the contextual constraints and the semantics of the configuration requirements and guidelines used to configure the C-EPC process models are unclear. Feature-EPC improve C-EPC with domain modeling capability and clearly defined configuration rules: their syntax, contextual constraints and semantics have been clearly defined using a context free grammar in Backus-Naur form. Furthermore, consistent combinations of features and configuration rules are ensured using respectively constraints and a conflict resolution algorithm. However, Feature-EPC and C-EPC suffer from the same weakness: large configurable process models. In COV-EPC and PCL-EPC the problem of large configurable process models is solved. COV-EPC ensures consistent combinations of options and configuration rules using respectively validities and a conflict resolution algorithm. PCL-EPC guarantees consistent combinations of process fragments by means of a PCL specification

The uses of process modeling : a framework for understanding modeling formalisms

There is wide-spread recognition of the urgent need to improve software processes in order to improve the performance of software organizations. Process models are essential in achieving understanding and visibility of processes and are important for other uses including the analysis of processes for improvement. It has been increasingly difficult to compare and evaluate the variety of process modeling formalisms that have appeared in recent years without a clear understanding of precisely for what they will be used. The contribution of this paper is to provide an understanding and a fairly comprehensive catalog of the applications of process modeling for which formalisms may be used. The primary mechanism for doing this is a guided tour of the literature on process modeling supplemented by recent industrial experience. In the paper, basic definitions concerning processes, process descriptions and process modeling are reviewed and then uses of process modeling are surveyed under the following headings: communication among process participants, construction of new processes, control of processes, process· analysis, and process support by automation. Comments are offered on paradigms for process modeling formalisms and directions for future work to permit evolution of a discipline of process engineering are given

A robot hand testbed designed for enhancing embodiment and functional neurorehabilitation of body schema in subjects with upper limb impairment or loss.

Many upper limb amputees experience an incessant, post-amputation "phantom limb pain" and report that their missing limbs feel paralyzed in an uncomfortable posture. One hypothesis is that efferent commands no longer generate expected afferent signals, such as proprioceptive feedback from changes in limb configuration, and that the mismatch of motor commands and visual feedback is interpreted as pain. Non-invasive therapeutic techniques for treating phantom limb pain, such as mirror visual feedback (MVF), rely on visualizations of postural changes. Advances in neural interfaces for artificial sensory feedback now make it possible to combine MVF with a high-tech "rubber hand" illusion, in which subjects develop a sense of embodiment with a fake hand when subjected to congruent visual and somatosensory feedback. We discuss clinical benefits that could arise from the confluence of known concepts such as MVF and the rubber hand illusion, and new technologies such as neural interfaces for sensory feedback and highly sensorized robot hand testbeds, such as the "BairClaw" presented here. Our multi-articulating, anthropomorphic robot testbed can be used to study proprioceptive and tactile sensory stimuli during physical finger-object interactions. Conceived for artificial grasp, manipulation, and haptic exploration, the BairClaw could also be used for future studies on the neurorehabilitation of somatosensory disorders due to upper limb impairment or loss. A remote actuation system enables the modular control of tendon-driven hands. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. The provision of multimodal sensory feedback that is spatiotemporally consistent with commanded actions could lead to benefits such as reduced phantom limb pain, and increased prosthesis use due to improved functionality and reduced cognitive burden

Providing Customized Real Time Traffic Information Through the Internet: Implementation Using GIS

For my Masters thesis I implement a web enabled GIS application for presenting personalized real-time traffic condition information. Due to the dynamic nature of traffic condition reporting, often large amounts of data have to be reported. The process of introducing personalization to traffic condition reporting hopes to reduce the amount of such data transmitted to users. The personalization of the presented traffic condition information is achieved by storing geographic definitions of routes and travel zones frequently traveled by the client. Since traffic update areas frequently requested for daily travel routes are often geographically identical, stored routes or zones can be used within a Geographic Information System (GIS) environment to retrieve traffic volume information and visualize the intended route before the start of the client\u27s routine daily trip. This saves both browsing time and data uploading for the client. The research implements such tools in a server-side (most of the processing done on the server) environment. The research concludes that existing GIS tools can be enhanced to implement the concept of using customized traffic profiles to transmit user specific traffic data

Companies need to realize the degree of customization appreciated by the customers and the extent of customization that can be offered competitively. This research is an effort to develop an approach to ascertain the product configurator requirements to achieve mass customization. The frameworks developed for this research are validated with a case study

Development of the huggable social robot Probo: on the conceptual design and software architecture

This dissertation presents the development of a huggable social robot named Probo. Probo embodies a stuffed imaginary animal, providing a soft touch and a huggable appearance. Probo's purpose is to serve as a multidisciplinary research platform for human-robot interaction focused on children. In terms of a social robot, Probo is classified as a social interface supporting non-verbal communication. Probo's social skills are thereby limited to a reactive level. To close the gap with higher levels of interaction, an innovative system for shared control with a human operator is introduced. The software architecture de nes a modular structure to incorporate all systems into a single control center. This control center is accompanied with a 3D virtual model of Probo, simulating all motions of the robot and providing a visual feedback to the operator. Additionally, the model allows us to advance on user-testing and evaluation of newly designed systems. The robot reacts on basic input stimuli that it perceives during interaction. The input stimuli, that can be referred to as low-level perceptions, are derived from vision analysis, audio analysis, touch analysis and object identification. The stimuli will influence the attention and homeostatic system, used to de ne the robot's point of attention, current emotional state and corresponding facial expression. The recognition of these facial expressions has been evaluated in various user-studies. To evaluate the collaboration of the software components, a social interactive game for children, Probogotchi, has been developed. To facilitate interaction with children, Probo has an identity and corresponding history. Safety is ensured through Probo's soft embodiment and intrinsic safe actuation systems. To convey the illusion of life in a robotic creature, tools for the creation and management of motion sequences are put into the hands of the operator. All motions generated from operator triggered systems are combined with the motions originating from the autonomous reactive systems. The resulting motion is subsequently smoothened and transmitted to the actuation systems. With future applications to come, Probo is an ideal platform to create a friendly companion for hospitalised children

Adaptation to the Needs of Subsidiaries

This study used institutional theory as a lens to understand how far institutional factors affect Accounting Information Systems adoption (integrated in an Enterprise Resource Planning system) and use in a subsidiary. For this purpose and after an extensive review of the literature on the topic an empirical study is done. The research approach is qualitative and a case study research method has been used. The relevant information is collected via semi-structured interviews. The result indicates that the large majority of daily basis tasks of the company studied depends on AIS (integrated in an Enterprise Resource Planning system) to function. And the fact that it is the Headquarters that chooses AIS/ERP to be used does not have a negative impact on the subsidiary company because the key factors are taken in considerations when selecting and implementing the system

Social Construction of Retail Digitalization: Managerial Perspectives

Digitalization is a pervasive movement, shifting society rapidly into the next industrial revolution and causing disruption to traditional ways of working. This movement has had major ramifications on brick and mortar retailers, redefining the traditional business model and offering opportunities to enhance the customer experience. The purpose of this study was to gain a holistic understanding of the digital transformation of retail from a retail manager’s perspective, thus, this study explores the ways in which retail managers are socially constructing retail digitalization. To address the lack of an established conceptualization of digitalization from a retail managers’ perspective, I applied an exploratory, framing analysis approach to this research gap. This procedure involved integrating field-based insights from 26 managers within the retail sector across Finland and the UK with supplementary literature on the topic of retail digitalization. Through conducting this research, three framing categories were identified, including: 1) investing in digital strategy and management, 2) changing organizational competences and mindset, and 3) shifting power to the retail customer, which were formulated based on nine managerial framings that were developed in the analysis. The findings indicate that though managers are aware of the various threats caused by digitalization, overall, they consider it a positive movement that stimulates innovation, offers new solutions, improves business processes, and enables a better service offering for customers. This study suggests that undergoing the digital transformation is not only a technological change in processes and systems, but a human change in terms of ways of thinking and working. The findings further indicate that retail managers must develop with the organization and have a thorough understanding of their business and the retail market. This study makes theoretical contributions by supporting ideas that are explored in existing literature such as the challenges related to creating the omni-channel business model, while adding the managerial perspective on various issues surrounding this organizational change. This study also contests some points made in the current literature on the death of high street by highlighting the hedonic value that brick and mortar retailers offer their customers which cannot be replaced by other channels. New perspectives were also contributed through this study by exploring how managers view data and analytics as important tools in organizational decision making and understanding the business. Finally, this study highlights an unexplored area in the literature, more specifically, the significance that retail managers place on the human side of the organization through the digital transformation
