Mobile app stores like Apple's AppStore or Google's Play-Store are highly competitive markets for third-party developers wanting to develop successful applications. During the development process, many developers focus on the multitude of product functions but neglect the business model as an equally important part. As a result, developers often fail to meet customer needs, leading to unnecessary development costs and poor market penetration. This, in turn, raises the question of how we intertwine the business model and product functions during the development process to ensure a better alignment between the two. In this paper, we show this intertwined development by adapting the concept of Twin Peaks to the business model and product functions. Based on feature modeling as an abstraction layer, we introduce the concept of a Business Model Decision Line (BMDL) to structure the business model decisions and their relation to product functions structured in a Software product Line (SPL). The basis of our feature models is the analysis of top listed applications in the app stores of Apple and Google. To create and modify both models, we provide an incremental feature structuring and iterative feature selection process. This combination of abstraction layer and development process supports third-party developers to build successful applications both from a business and a product perspective.

This article investigates how the industry shift from traditional cell phones to smartphones has impacted the process of customer value creation and thus caused the rapid demise of industry leaders and the rise of new global leaders. It explores this mechanism within the chain from quality-induced and customer-co-created product functionality via hedonic, symbolic, and utilitarian customer value to customer loyalty. Based on consumer data from Bolivia and Japan, the study illustrates that the greater market success of smartphones than traditional cell phones can mainly be explained by higher hedonic and symbolic value creation. This additional value creation is caused by higher product quality and greater opportunities for customers to co-create value through active usage of customized product functions.

A rotating machinery fault diagnosis method based on local mean decomposition

Local mean decomposition (LMD) is a novel self-adaptive time-frequency analysis method, which is particularly suitable for the processing of multi-component amplitude-modulated and frequency-modulated (AM-FM) signals. By using LMD, any complicated signal can be decomposed into a number of product functions (PFs), each of which is the product of an envelope signal and a purely frequency modulated signal from which physically meaningful instantaneous frequencies can be obtained. In fact, each PF is just a mono-component AM-FM signal. Therefore, the procedure of LMD may be regarded as the process of demodulation. While fault occurs in gear or roller bearing, the vibration signals picked up would exactly display AM-FM characteristics. So it is possible to diagnose gear and roller bearing fault by LMD. Targeting the modulation features of the gear or roller bearing fault vibration signal, a rotating machinery fault diagnosis method based on LMD is proposed. In this paper, firstly the LMD method is introduced;secondly, the LMD method is compared with another competing time-frequency analysis approach, namely, empirical mode decomposition (EMD) method and the results show the superiority of the LMD method;finally, the LMD method is applied to the gear and roller bearing fault diagnosis. The analysis results from the practical gearbox vibration signal demonstrate that the diagnosis approach based on LMD could identify gear and roller bearing work condition accurately and effectively.

Modeling and evaluation of product quality at conceptual design stage

Quality of a product is a function of many variables. These have been identified, and modeled in terms of quality digraph. The nodes in the digraph represent the quality features and the edges represent the degree of influence among these. An equivalent matrix representation of the digraph is developed to define the product system quality function (PSQF). Quality index (QI) is defined as a ratio of the actual to the ideal values of PSQF. The designer may use this index to evaluate and compare alternative designs and choose the best among these from the perspective of quality. A high value of QI indicates that the product structure is closer to the ideal state. The presented model is illustrated with an example.

With the continuous development and improvement as well as the wide application in the digital area, the digital media technology affects each industry more and more profoundly. Meantime, the fast growing digital media technology also provides brand new contents to the modern product design. The new contents not only broaden the technological space and cultural space for the design process, but also impose significant impact on aesthetic shape of products. The revolutionary technology innovation changes not only the contents and method of product design, but also the structure, functions, and aesthetic characteristics of products, consumption habit, and social status quo. Like many post-modern product designs, the developing digital media technology will challenge the modern functionalism design. With the application of the digital media technology, we must rethink about the problems related to functions, society, technology impact on design, and materials.

The study demonstrates the use of a hybrid method for condition monitoring of rotary machines. The multi-scale fluctuation based dispersion entropy (MFDE) is hybrid with a local mean decomposition (LMD) to analysis the bearing faults. The acquired bearing signals are decomposed using LMD. MFDE values of decomposed signals are computed and are used as feature vectors in the present study. Support vector machine (SVM) is used as machine learning tool for classifying the different levels of fault severity. This study shows that, the proposed hybrid method has potential for gaining further insights into the dynamics of rotary machines. (C) 2020 Elsevier Ltd. All rights reserved.

The perception of pleasantness in a product of collective use: the bus shelter

WORK-A JOURNAL OF PREVENTION ASSESSMENT & REHABILITATION 2012年第Sup1期41卷 282-289页

This article presents a study on the identification of a setting whose arrangement of attributes could lead to the perception of pleasantness of a bus shelter: a product that should welcome people while waiting for the bus. Two different bus shelters typologies in the city of Porto Alegre, state of Rio Grande do Sul, Brazil, were evaluated, where four attributes were under consideration. The relation between the shelters subject of the study and the surroundings was significant for defining the attributes. The setting with curve shaped cover, bench, rear wall, and surrounding vegetation was considered the most pleasant one. The seats and the rear wall were associated with the practical function of the product while the curve shaped cover and the surrounding vegetation were associated with the aesthetical function according to the participant users.
