AbstractAdditive manufacturing (AM) is a versatile technology that could add flexibility in manufacturing processes, whether implemented alone or along other technologies. This technology enables on-demand production and decentralized production networks, as production facilities can be located around the world to manufacture products closer to the final consumer (decentralized manufacturing). However, the wide adoption of additive manufacturing technologies is hindered by the lack of experience on its implementation, the lack of repeatability among different manufacturers and a lack of integrated production systems. The later, hinders the traceability and quality assurance of printed components and limits the understanding and data generation of the AM processes and parameters. In this article, a design strategy is proposed to integrate the different phases of the development process into a model-based design platform for decentralized manufacturing. This platform is aimed at facilitating data traceability and product repeatability among different AM machines. The strategy is illustrated with a case study where a car steering knuckle is manufactured in three different facilities in Sweden and Italy.

Operational Excellence

Currently, manufacturing is characterized by increasing complexity both on the technical and organizational levels. Thus, more complex and intelligent production control methods are developed in order to remain competitive and achieve operational excellence. Operations management described early on the influence among target metrics, such as queuing times, queue length, and production speed. However, accurate predictions of queue lengths have long been overlooked as a means to better understanding manufacturing systems. In order to provide queue length forecasts, this paper introduced a methodology to identify queue lengths in retrospect based on transitional data, as well as a comparison of easy-to-deploy machine learning-based queue forecasting models. Forecasting, based on static data sets, as well as time series models can be shown to be successfully applied in an exemplary semiconductor case study. The main findings concluded that accurate queue length prediction, even with minimal available data, is feasible by applying a variety of techniques, which can enable further research and predictions.

This study aims to examine the features of the creation and operation of ecomuseums at wide-area and (metropolitan) local government levels and to analyze their improvements and limitations based on an analysis of a case study on the “Gyeonggi Bay Ecomuseum.” This study also reveals the necessity and direction for ecomuseums led by metropolitan local governments. It attempts to find ways to expand the Gyeonggi Bay Ecomuseum and apply lessons from this ecomuseum to other planned wide-area ecomuseums in South Korea. Overall, this study intends to derive the sustainability of wide-area ecomuseums, and their utility and potential as a means to revitalize the region.  The Gyeonggi Bay Ecomuseum is a meaningful case study as it was created in a wide area called the Gyeonggi Bay and was led by a metropolitan local government, along with the official claim as an ecomuseum; the museum creation project also progressed in a phased approach. However, there are issues such as organization problems of the ecomuseum and the absence of resident participation, integrated programs, and an archive center.  Therefore, this study presents measures to overcome these obstacles: the establishment of a core ecomuseum and an exhibition center, the development of joint programs, the continuous security of funds and human resources, and measures to generate economic benefits for residents. This study also suggests spatial/functional expansion from being the “Gyeonggi Bay Ecomuseum” to the “Gyeonggi Province Ecomuseum.”   Keywords: Ecomuseum, Wide-area unit, Lead of local governments, Gyeonggi Bay, Regional revitalization
