What benefits couldn't ‘Joyn’ enjoy?
Abstract This case study examines the dynamics of the mobile instant messenger (MIM) market in Korea. MIMs have been disrupting traditional mobile communication services such as voice, SMS, and media content. In response to MIMs, Korean Mobile Network Operators (MNOs) jointly launched a standards-based messenger service called Joyn, which ultimately performed poorly. Focusing on Joyn, this study analyses the changing status of MNOs and their counter-strategies against MIMs in the context of the turbulent mobile services market. For the analysis, we use a co-evolutionary framework encompassing technological, market, and regulatory domains and apply a platform competition perspective. The cas…
Optimization Model to Extend Existing Production Planning and Control Systems for the Use of Additive Manufacturing Technologies in the Industrial Production
Abstract The use of additive manufacturing technologies for industrial production is constantly growing. This technology differs from the known production procedures. The areas of scheduling, detailed and sequence planning are particularly important for additive production due to the long print times and flexible use of the production area. Therefore, production-relevant variables are considered and used for the production planning and control (PPC) of additive manufacturing machines. For this purpose, an optimization model is presented which shows a time-oriented build space utilization. In the implementation, a nesting algorithm is used to check the combinability of different models for e…
How to Distribute a Cake before Cutting It into Pieces
This article analyses social networks by looking at the standard making processes. As a framework for analysis, actor network theory is chosen. Standards are of particular interest for actor network theory for they provide mechanisms to align interests of multiple social groups organized in networks that have a joint incentive in working with the standards and /or associated technologies. These social groups include scientific communities, government institutions and social movements (industrial groups, companies, and consumers) that are interested in regulating and innovating with new technologies. Standards provide the mechanisms to inscribe subsequent behaviors that are expected to becom…
