Towards Digital Transformation in Fashion Retailing: A Design-Oriented IS Research Study of Automated Checkout Systems

Automated checkout systems promise greater sales due to an improved customer experience and cost savings because less store personnel is needed. The present design-oriented IS research study is concerned with an automated checkout solution in fashion retail stores. The implementation of such a cyberphysical system in established retail environments is challenging as architectural constraints, well-established customer processes, and customer expectations regarding privacy and convenience impose limits on system design. To overcome these challenges, the authors design an IT artifact that leverages an RFID sensor infrastructure and software components (data processing and prediction routines) to jointly address the central problems of detecting purchases in a reliable and timely fashion and assigning these purchases to individual shopping baskets. The system is implemented and evaluated in a research laboratory under real-world conditions. The evaluation indicates that shopping baskets can indeed be detected reliably (precision and recall rates greater than 99%) and in an expeditious manner (median detection time of 1.03 s). Moreover, purchase assignment reliability is 100% for most standard scenarios but falls to 42% in the most challenging scenario

A Survey of Languages for Specifying Dynamics: A Knowledge Engineering Perspective

A number of formal specification languages for knowledge-based systems has been developed. Characteristics for knowledge-based systems are a complex knowledge base and an inference engine which uses this knowledge to solve a given problem. Specification languages for knowledge-based systems have to cover both aspects. They have to provide the means to specify a complex and large amount of knowledge and they have to provide the means to specify the dynamic reasoning behavior of a knowledge-based system. We focus on the second aspect. For this purpose, we survey existing approaches for specifying dynamic behavior in related areas of research. In fact, we have taken approaches for the specification of information systems (Language for Conceptual Modeling and TROLL), approaches for the specification of database updates and logic programming (Transaction Logic and Dynamic Database Logic) and the generic specification framework of abstract state machine

Embodiment in 3D virtual retail environments: exploring perceptions of the virtual shopping experience

The customer can now easily create, and customize, their own personal three dimensional (3D) virtual bodies in a variety of virtual environments; could you, by becoming a virtual body, actually enhance your online shopping and buying experiences or, would this potentially inhibit the pure visceral pleasure of retail therapy? "Second Life allows you to be a celebrity in your own lunchtime, .…you can design the body you've always wanted, and indulge your fashionista fetish for very little money. You can be the most attractive, best-dressed version of yourself you can imagine." This paper investigates online shopping in Second Life, through the experience of being avatars. We will discuss the possibilities of using avatars as brand new consumer identities for personalised and customised fashion shopping within the 3D multi user virtual environment, and question the influences and effects of these developments on the traditional high street shopping trip. The hyper un-realistic and non-sensory interface of online shopping for clothes has been hotly debated over the last decade; through the media, the industry and most importantly by the buying public. The customer’s inability to try on and experience the product has been the main inhibitor to shopping on-line, and the high levels of product returns in home shopping dramatically reflect this reality. Faster broadband connections and improved 2D web sites are making clothes shopping on the web more accessible, and for important customer groups, such as young professional females, and plus-size teenagers, virtual 3D technologies offer freedom of choice in any location. Retailers are now confidently providing different shopping experiences by combining 2D and 3D interactive visualisation technologies with advanced marketing techniques, to create virtual retail environments that attempt to actualise the true essence of shopping; by browsing, socialising, trying-on before buying and, in a new twist, leaving the store proudly wearing the item just purchased. American Apparel, Bershka, L’Oreal, Calvin Klein, Reebok, Sears, Nike and Adidas are pioneering virtual mega stores, and all offer newly innovative, and alternative shopping experiences inside 3D multi user virtual environments. An experiential and exploratory approach will be used to investigate fashion brands, and their virtual 3D stores in Second Life. As 3D avatars, we will record a range of customer perceptions and attempt to map their shopping patterns in this massively popular virtual world. The qualitative data gathered will inform discussions about the value of the virtual shopping experience for the customer and the retailer. Conclusions will also question the possibility of using avatars in a virtual shopping environment to acquire accurate body specifications for better fit and the collection of personal details for use in the future development of alternative shopping experiences

Semantic business process management: a vision towards using semantic web services for business process management

Business process management (BPM) is the approach to manage the execution of IT-supported business operations from a business expert's view rather than from a technical perspective. However, the degree of mechanization in BPM is still very limited, creating inertia in the necessary evolution and dynamics of business processes, and BPM does not provide a truly unified view on the process space of an organization. We trace back the problem of mechanization of BPM to an ontological one, i.e. the lack of machine-accessible semantics, and argue that the modeling constructs of semantic Web services frameworks, especially WSMO, are a natural fit to creating such a representation. As a consequence, we propose to combine SWS and BPM and create one consolidated technology, which we call semantic business process management (SBPM

Higher-Order Process Modeling: Product-Lining, Variability Modeling and Beyond

We present a graphical and dynamic framework for binding and execution of business) process models. It is tailored to integrate 1) ad hoc processes modeled graphically, 2) third party services discovered in the (Inter)net, and 3) (dynamically) synthesized process chains that solve situation-specific tasks, with the synthesis taking place not only at design time, but also at runtime. Key to our approach is the introduction of type-safe stacked second-order execution contexts that allow for higher-order process modeling. Tamed by our underlying strict service-oriented notion of abstraction, this approach is tailored also to be used by application experts with little technical knowledge: users can select, modify, construct and then pass (component) processes during process execution as if they were data. We illustrate the impact and essence of our framework along a concrete, realistic (business) process modeling scenario: the development of Springer's browser-based Online Conference Service (OCS). The most advanced feature of our new framework allows one to combine online synthesis with the integration of the synthesized process into the running application. This ability leads to a particularly flexible way of implementing self-adaption, and to a particularly concise and powerful way of achieving variability not only at design time, but also at runtime.Comment: In Proceedings Festschrift for Dave Schmidt, arXiv:1309.455

Turning an Idea into a Valuable Teaching Resource and Research Output

This paper describes the journey of a teacher who became an author in Higher Education. The journey began with a simple idea about a fundamental resource book, designed to improve teaching in design and illustration classes with ever increasing numbers of novice fashion students, back in 1991. This resource was a taxonomy of fashion, designed to increase the awareness of garment shapes, context, proportion, terminology, construction, production and finish with a view to improving student knowledge, design and visual communication skills. The paper reflects upon the subsequent publications that built on the previous resource, as outputs of rigour, significance and integrity in shaping the author‘s approaches to teaching and research in fashion and other disciplines. It describes the development of the original idea and the subsequent acceptance of this for publication and illustrates how this one idea allowed for further opportunities for publications in a partnership with a global publisher. There are resource issues around gathering content for publications of rigour and originality and there have been challenges around communicating in the publications themselves due to technological and economical constraints. There are also practical resource issues around creating and designing the publications as well as the need for the development of personal skills when keeping up with changes in technology and the fashion industry. Each publication requires careful planning and needs to have unique reasons for being‘ that make it different to the competition. It describes the positive aspects of working with a colleague who brings similar skills and understanding, but a different handwriting and point of view to the publications. It looks at the impact of updating original editions and keeping the works contemporary. It also looks at personal and practical insights learned across almost 20 years of being an author with the same publisher

The strategic integration of agile and lean supply

Lean supply is closely associated with enabling flow and the elimination of wasteful variation within the supply chain. However, lean operations depend on level scheduling and the growing need to accommodate variety and demand uncertainty has resulted in the emergence of the concept of agility. This paper explores the role of inventory and capacity in accommodating such variation and identifies how TRIZ separation principles and TOC tools may be combined in the integrated development of responsive and efficient supply chains. A detailed apparel industry case study is used to illustrate the application of these concepts and tools

Bayesian Optimization for Probabilistic Programs

We present the first general purpose framework for marginal maximum a posteriori estimation of probabilistic program variables. By using a series of code transformations, the evidence of any probabilistic program, and therefore of any graphical model, can be optimized with respect to an arbitrary subset of its sampled variables. To carry out this optimization, we develop the first Bayesian optimization package to directly exploit the source code of its target, leading to innovations in problem-independent hyperpriors, unbounded optimization, and implicit constraint satisfaction; delivering significant performance improvements over prominent existing packages. We present applications of our method to a number of tasks including engineering design and parameter optimization
