The Impact

AbstractNowadays the transport sector is one of the most challenging sectors in terms of reducing pollution produced in this sector. It becomes more and more clear that one of the best solutions for mitigating this pollution and the climate change linked to it is the usage of electrified railway. The aim of this article is to evaluate the impact that electrification of the railway will have on the environment from the perspective of pollution. The article shows a system dynamics model, which is based upon factors that affect a newly electrified railway. These include power demand, economics and the environmental impact originating from the railway. This model can be applicable for any country, however in this article Latvia is modelled as an example of how the model works and how the environmental factors will change as a result of an electrification of Latvia’ s railway system.

Modelling Task

AbstractTo pursue business innovation with PSS, many different PSS concepts are designed and evaluated. Various business models of a PSS design concept are devised and evaluated as well. Evaluation of the economic sustainability of PSS business models is critical. This paper presents a systematic method to evaluate the economic sustainability of PSS business models using a system dynamics modelling template. System dynamics modelling task is challenging for practitioners due to the variety of variables comprising business model strategies and their complex interrelationships. To enable the modelling task, a system dynamics modelling template composed of six modules of customer acquisition, channel acquisition, profit creation, resource acquisition, PSS provision, and partnership pattern has been devised. The PSS business model evaluation method has been illustrated using a smart study experience management service system design case to demonstrate the proposed system dynamics modelling template can reflect the case-specific business model which consists of the particular business model strategies.
