Towards an Extended Interoperability Systemic Approach for Dynamic Manufacturing Networks: Role and Assessment of PLMStandards

Abstract. This paper aims at illustrating some limitations of the systemic approach when will-ing to ensure the interoperability of PLM solutions within a Dynamic Manufacturing Network (DMN), based on e-Business PLM standards and their implementations, being industrial pro-cesses, methods, applications or Information & Communication Technologies (ICT) solutions. Indeed, addressing interoperability challenges in such a complex digital business eco-system calls for a holistic approach based on the “system ” paradigm. Setting this way, a part of our goal is to underline the limits and drawbacks of such an approach as interoperability brakes and to derive the issues that must be addressed in terms of research in order to remove them. This paper introduces a new approach in order to set up a test bed environment for PLM standards. The required and proposed approach considers a PLM standard not only as a technical solution, but above all as a strategic solution for which it is mandatory to support and enhance discus-sions between enterprise, product/system, processes, ICT architects and designers. The pro-posed approach- for analyzing and assessing the relevancy of PLM standards regarding their usage in specific business contexts- will be illustrated with a multi-layer modeling language. This language is used to model standards-based business collaboration scenarios and to mode

Microservice Transition and its Granularity Problem: A Systematic Mapping Study

Microservices have gained wide recognition and acceptance in software industries as an emerging architectural style for autonomic, scalable, and more reliable computing. The transition to microservices has been highly motivated by the need for better alignment of technical design decisions with improving value potentials of architectures. Despite microservices' popularity, research still lacks disciplined understanding of transition and consensus on the principles and activities underlying "micro-ing" architectures. In this paper, we report on a systematic mapping study that consolidates various views, approaches and activities that commonly assist in the transition to microservices. The study aims to provide a better understanding of the transition; it also contributes a working definition of the transition and technical activities underlying it. We term the transition and technical activities leading to microservice architectures as microservitization. We then shed light on a fundamental problem of microservitization: microservice granularity and reasoning about its adaptation as first-class entities. This study reviews state-of-the-art and -practice related to reasoning about microservice granularity; it reviews modelling approaches, aspects considered, guidelines and processes used to reason about microservice granularity. This study identifies opportunities for future research and development related to reasoning about microservice granularity.Comment: 36 pages including references, 6 figures, and 3 table

Urban lifecycle management: A research program for smart government of smart cities

At date, there is no standardized definition of what a smart city is, in spite many apply to propose a definition that fit with their offer, subsuming the whole of the city in one of its functions (smart grid, smart mobility…). Considering the smart cities as an ecosystem, that is to say a city that has systemic auto poeitic properties that are more than the sum of its parts, we develop an approach of modeling the smartness of the city. To understand how the city may behave as a sustainable ecosystem, we need a framework to design the interactions of the city subsystems. First we define a smart city as an ecosystem that is more than the sum of its parts, where sustainability is maintained through the interactions of urban functions. Second, we present a methodology to sustain the development over time of this ecosystem: Urban Lifecycle Management. Third, we define the tasks to be carried out by an integrator of the functions that constitute the smart city, we assume public administration has to play this role. Fourth, we present what should be a smart government for the smart city and the new capabilities to be developed.At date, there is no standardized definition of what a smart city is, in spite many apply to propose a definition that fit with their offer, subsuming the whole of the city in one of its functions (smart grid, smart mobility…).

Innovative urban temporalities: conceptive and generative temporal regimes

International audienceIn this paper, we outline management science in a manner that, we hope, will aid future research on individual and city temporalities. Our research question is twofold, but intertwined: how societal temporalities could be innovative understood as conceptive (" aspect of mind that can be used to conceive our world anew 1 ") and generative (" having the power of producing or originating 2 " ,)? How firms could contribute to times design in an innovative way? From our perspective, these questions could be even more generic if we accept the general assumption that firms could be societal mutations producers or contributors. In that, we put aside ethical questions we don't underestimate to concentrate on interactions between societal change, here new time organization, and firm management in public transport sector. First, we propose a social and technical times science overview to better understand contemporary times factory that we observed through two case studies led in intervention-research. That will give a useful framework to underline firm contributions to times design since 19 th. Secondly, that baseline will be used to integrate more specific literature on management science, particularly in organization and design topics. Before going on our vision of conceptive temporalities, we need to clarify some definitions we will use in that paper: times, temporalities, rhythm and temporal regime. We'll speak about times, and not " time " in Augustinian sense (" What, then, is time? If no one asks me, I know; if I want to meet this demand, I do not know ") to mean that time could be polychronical and be described by its manifestations. Using temporalities, we refer to " character of what is in time and time consciousnes

Managed Evolution of Automotive Software Product Line Architectures: A Systematic Literature Study

The rapidly growing number of software-based features in the automotive domain as well as the special requirements in this domain ask for dedicated engineering approaches, models, and processes. Nowadays, software development in the automotive sector is generally developed as product line development, in which major parts of the software are kept adaptable in order to enable reusability of the software in different vehicle variants. In addition, reuse also plays an important role in the development of new vehicle generations in order to reduce development costs. Today, a high number of methods and techniques exist to support the product line driven development of software in the automotive sector. However, these approaches generally consider only partial aspects of development. In this paper, we present an in-depth literature study based on a conceptual model of artifacts and activities for the managed evolution of automotive software product line architectures. We are interested in the coverage of the particular aspects of the conceptual model and, thus, the fields covered in current research and research gaps, respectively. Furthermore, we aim to identify the methods and techniques used to implement automotive software product lines in general, and their usage scope in particular. As a result, this in-depth review reveals that none of the studies represent a holistic approach for the managed evolution of automotive software product lines. In addition, approaches from agile software development are of growing interest in this field

Market Structure and Energy Efficiency: The Case of New Commercial Buildings

This is a report on why commercial office buildings aren’t more energy efficient. Several decades of energy efficiency programs have resulted in some gains, but overall increases in the energy efficiency of buildings have fallen far short of the 30 to 50 percent improvement that many efficiency advocates believe is possible. The purpose of this study is to consider the “why” question by empirically examining the dynamics of new commercial building markets. To do so, the authors used multiple research techniques, including qualitative field observation and interview methods that allow for a more in-depth understanding of complicated market processes. Their research focused primarily on new office buildings and centered in four regional markets: Sacramento, San Francisco, Seattle, and Portland. The authors identify key dynamics of commercial office building markets, describe how change and innovation occurs in commercial development, discuss the implications for energy efficiency, and suggest next steps
