ABSTRACTProduct development, especially in aerospace, has become more and more interconnected with its operational environment. In a constant changing world, the operational environment will be subjected to changes during the life cycle of the product. The operational environment will be affected by not only technical and non-technical perturbations, but also economical, managerial and regulatory decisions, thus requiring a more global product development approach. One way to try tackling such complex and intertwined problem advocates studying the envisioned product or system in the context of system of systems (SoS) engineering. SoSs are all around us, probably in any field of engineering, ranging from integrated transport systems, public infrastructure systems to modern homes equipped with sensors and smart appliances; from cities filling with autonomous vehicle to defence systems.Since also aerospace systems are certainly affected, this work will present a holistic approach to aerospace product development that tries spanning from needs to technology assessment. The proposed approach will be presented and analysed and key enablers and future research directions will be highlighted from an interdisciplinary point of view. Consideration of the surrounding world will require to look beyond classical engineering disciplines.

Strategic Capabilities

Service-dominant (S-D) logic can function as a strategic business logic that portrays creating superior value in conjunction with—rather than for—customers as a source of competitive advantage for organizations. From this perspective, strategy is about making choices in terms of how to best facilitate and enhance value cocreation for mutual and long-term betterment. While the literature has pointed out the managerial merits of cocreating value, less is known about the organizational capabilities necessary to execute S-D logic in practice. This article devises an S-D orientation, specified as a portfolio of six strategic capabilities, namely individuated, relational, ethical, empowered, developmental, and concerted interaction capability. In combination, these six strategic capabilities constitute a cocreation capability. The authors develop the conceptual model of S-D orientation through (a) an in-depth literature review and (b) input from 21 expert academics. Conceptualizing S-D orientation provides a foundation for bridging S-D logic and strategy research with a more general framework, and for guiding much-needed empirical research that will inform managers. From a managerial point of view, S-D orientation provides a holistic approach to align the organization with its value network partners. The article also sets out an agenda for future research.

Abstract This paper describes challenges faced by companies that form partnership with global suppliers in developing an integrated product. Many experts agree that concurrent product development (CPD) across the supply chain is the next significant challenge in design for manufacturability. Effective management of this process is a key to achieve superior time-to-market and life cycle quality. Drawing on a recent Global Supply Chain Seminar at Stanford, the paper first surveys the challenges faced by various companies ranging from electronics and automotive to aircraft engines. From the survey emerges some key and common issues that these, companies face: cultural barriers, product definition and joint product development practices. The paper then identifies the need for a systematic tool to achieve robust development strategies under uncertainties associated with global partnerships. A proposed robust development approach includes strategies such as key tuning parameters and functional redundancies. The paper concludes by presenting an idealized CPD process and future research agenda.

The purpose of this study is to measure the existence of co-creation behavior between doctors and patients. The research also studies customer participation and customer citizenship behavior as the dimensions of co-creative behavior and tries to establish the relationship between co-creative behavior and satisfaction. This study uses Yi and Gong (2013) scale for collecting data regarding co-creation behavior and its dimensions which are customer participation (CP) and customer citizenship behavior (CCB). The data was collected from 204 patients who were suffering from various chronic/lifestyle diseases and getting their treatment from private clinics in Jammu city. The study uses 7-point Likert scale in the questionnaire ranging from 1 completely disagree through 7 completely agree, with a midpoint labeled 4 neither agree nor disagree. The analysis of paper reflects that co-creation behavior is prevalent among the patients and not only participation but the citizenship behavior also affects the co-creation behavior of patients. The study is conducted from patients point of view whereas doctors perspective should also be used in future research. The research area is restricted to Jammu city only. The research provides several implications-doctors can also use this scale for market segmentation and customer profiling for maximizing customer value co-creation behavior by gaining the useful information.

Using intelligent transport systems in cities is gaining popularity. The fundamental aim of their existence is to improve safety and traffic flow and prevent congestion in city centres. All people moving around the city, such as public transport passengers, as well as truck and emergency vehicle drivers and drivers of passenger vehicles, are users of intelligent transport systems. Research which was carried out for the article entirely concerns functioning and utility of intelligent transport systems from truck drivers’ experience. The main aim of the research was to evaluate services and tools within intelligent transport systems in European cities which are visited by Polish truck drivers. Our research indicates that most drivers (almost 98%) stated that they find intelligent transport systems useful and 92.5% of interviewed pointed that intelligent transport systems help with their everyday work duties. Of all the tools in the survey drivers agreed that variable content signs, accommodative traffic lights, and extra road illumination have most influence in road safety. Identifying the most useful and helpful tools of intelligent transport systems will allow to define their preferred development directions from truck drivers’ point of view.

Condition monitoring of rail transport systems has become a phenomenon of global interest over the past half a century. The approaches to condition monitoring of various rail transport systems—especially in the context of rail vehicle subsystem and track subsystem monitoring—have been evolving, and have become equally significant and challenging. The evolution of the approaches applied to rail systems’ condition monitoring has followed manual maintenance, through methods connected to the application of sensors, up to the currently discussed methods and techniques focused on the mutual use of automation, data processing, and exchange. The aim of this paper is to provide an essential overview of the academic research on the condition monitoring of rail transport systems. This paper reviews existing literature in order to present an up-to-date, content-based analysis based on a coupled methodology consisting of bibliometric performance analysis and systematic literature review. This combination of literature review approaches allows the authors to focus on the identification of the most influential contributors to the advances in research in the analyzed area of interest, and the most influential and prominent researchers, journals, and papers. These findings have led the authors to specify research trends related to the analyzed area, and additionally identify future research agendas in the investigation from engineering perspectives.

Information-Centric Networking (ICN) has recently emerged as a prominent candidate for the Future Internet Architecture (FIA) that addresses existing issues with the host-centric communication model of the current TCP/IP-based Internet. Named Data Networking (NDN) is one of the most recent and active ICN architectures that provides a clean-slate approach for Internet communication. NDN provides intrinsic content security where security is directly provided to the content instead of communication channel. Among other security aspects, Access Control (AC) rules specify the privileges for the entities that can access the content. In TCP/IP-based AC systems, due to the client-server communication model, the servers control which client can access a particular content. In contrast, ICN-based networks use content names to drive communication and decouple the content from its original location. This phenomenon leads to the loss of control over the content, causing different challenges for the realization of efficient AC mechanisms. To date, considerable efforts have been made to develop various AC mechanisms in NDN. In this article, we provide a detailed and comprehensive survey of the AC mechanisms in NDN. We follow a holistic approach towards AC in NDN where we first summarize the ICN paradigm, describe the changes from channel-based security to content-based security, and highlight different cryptographic algorithms and security protocols in NDN. We then classify the existing AC mechanisms into two main categories: Encryption-based AC and Encryption-independent AC . Each category has different classes based on the working principle of AC (e.g., Attribute-based AC, Name-based AC, Identity-based AC). Finally, we present the lessons learned from the existing AC mechanisms and identify the challenges of NDN-based AC at large, highlighting future research directions for the community.

Vision-based Automated Vehicle Recognition (VAVR) has attracted considerable attention recently. Particularly given the reliance on emerging deep learning methods, which have powerful feature extraction and pattern learning abilities, vehicle recognition has made significant progress. VAVR is an essential part of Intelligent Transportation Systems. The VAVR system can fast and accurately locate a target vehicle, which significantly helps improve regional security. A comprehensive VAVR system contains three components: Vehicle Detection (VD), Vehicle Make and Model Recognition (VMMR), and Vehicle Re-identification (VRe-ID). These components perform coarse-to-fine recognition tasks in three steps. In this article, we conduct a thorough review and comparison of the state-of-the-art deep learning--based models proposed for VAVR. We present a detailed introduction to different vehicle recognition datasets used for a comprehensive evaluation of the proposed models. We also critically discuss the major challenges and future research trends involved in each task. Finally, we summarize the characteristics of the methods for each task. Our comprehensive model analysis will help researchers that are interested in VD, VMMR, and VRe-ID and provide them with possible directions to solve current challenges and further improve the performance and robustness of models.

Qualitative Changes

A review of the available empirical material bearing upon the question of alcohol advertising having ‘effects’ on the general level of consumption suggests that this question is insufficiently precise as a basis for research. Studies suggesting some relationship between advertising for particular brands or products and shifts in brand or product use are potentially more interesting, if considered from a point of view that recognises that such shifts may involve shifts in milieux, comparisons, styles and meanings associated with consumption. Future research should be attentive to such qualitative changes in drinking practices attendant upon advertising or preventive campaigns (as well as to quantitative changes). The authors suggest that such quantitative and qualitative changes in drinking practices of individuals and social groups need to be considered within the context of more general, ideological and economic, consequences of alcohol advertising. These consequences-including reinforcement of images about ‘social drinking,’ and shifting of consumers onto more profitable products-consolidate the profitability of the alcohol industry (a consideration more important to the industry than levels of consumption per se). A framework broader than that of ‘effects’ on individuals' levels of consumption is required if health educators are to learn anything from advertising.

As sustainability is becoming a common practice in planning transport systems and mobility services, the designation and management of gender issues are of paramount importance. TInnGO is a European Project that has developed a network of 10 national Hubs to build the capacity to generate and apply evidence on gender equality and transport issues at the European level. This paper presents the project activities by introducing a relevant framework and exploring user mobility experiences based on gender to identify diversified needs and requirements. This process relies on the combination of a review of current gender-oriented experiences and practices in mobility with focus group activities conducted in four different EU cities. The insights obtained from these activities supported the design of a survey to collect information on socioeconomic, personal, and operational aspects to serve a gender-oriented transport analysis for all the Hubs. These preliminary analyses identified the main issues related to the female mobility experience, namely safety, security, accessibility, and transport reliability. Future research on the data collected through the survey would help operators in successfully improving their mobility offer to women.
