We developed an empirical model to explain the changing global competition among major countries involved in the shipbuilding industry over the last three decades. In order to develop future strategies for not only shipbuilding companies but shipping companies and governments, it is necessary to...

In this paper, we propose a method of optimizing financial subsidies and public research and development investments for renewable energy technologies, rather than optimizing financial subsidy alone. By combining system dynamics with real option models, we capture dynamic complex interactions...

A new long-term technology valuation method for renewable energy technologies that combines system dynamics with Monte Carlo simulation is proposed. Existing valuation methods using surveys or cash flows are suitable for technologies characterized by short lifecycles and little uncertainty, but...

One of the flaws of the journal impact factor (IF) is that it cannot be used to compare journals from different fields or multidisciplinary journals because the IF differs significantly across research fields. This study proposes a new measure of journal performance that captures field-different...

An energy security management model using quality function deployment (QFD) and system dynamics (SD) is suggested for application in public policymaking in developing economies. Through QFD, experts are guided toward identifying key energy security components, including indicators and policies,...

The conceptual approach has contributed significantly to service productivity, but it should be complemented by practical deliverable methods. This paper proposes a systematic framework for improving service productivity by employing the failure mode and effect analysis-based portfolio approach....
