Communication of Simulation and Modelling Activities in Early Systems Engineering

In this paper we present a framework that aids and supports communication of modeling and simulation activities in early systems engineering. We do this by analyzing existing simulation and modelling frameworks, both in systems engineering as well as more generic frameworks. For each framework, we discuss its purpose, main outcomes and the tools and methods used in the framework. Using this overview, we argue that in order to apply simulation and modeling techniques fully in conceptual systems design, it is necessary to use a framework focused on communication and aimed at four key issues. We extract a generic process from the discussed frameworks and discuss for each step of this process how these issues should be addressed. We also explain how this framework should be supported with tooling. Finally we discuss a simulation study of a medical imaging system that gave us initial experiences on the approach presented here. We conclude that this framework shows promise in supporting the communication of a modeling and simulation study in a multidisciplinary settin

Business models in the shared electric mobility field: A market overview towards electric Mobility as a Service (eMaaS)

In response to the increasing demand for shared mobility and multimodal passenger transport services, new mobility concepts such as Mobility as a Service (MaaS) and electric Mobility as a Service (eMaaS) are becoming commonplace. However, in order for new MaaS and eMaaS providers to become competitive, innovative business models (BMs) and effective market strategies are needed. This paper presents a market analysis of 229 existing providers and mobile apps within the Shared Electric Mobility (SEM) field. The goal of the analysis presented in this paper is to provide an overview of both the current BMs used in practice and the state of the market for MaaS and eMaaS endeavours. The results of the analysis determine which are the strengths of the key players within the SEM market, and how the core characteristics of their BMs can contribute to the further development of eMaaS

An Overview of, and a Definition, Ecosystem and System Architecture for Electric Mobility as a Service (eMaaS)

Mobility as a Service (MaaS) is a concept that aligns with both current and future mobility demands of users, namely intermodal, personalized, on-demand and seamless. Although the number of shared mobility, electric mobility and multimodal passenger transport users is rapidly growing, until now, the list of MaaS and electric Mobility as Service (eMaaS) providers is quite short. This could partly be explained by the lack of a common architecture that facilitates the complex integration of all actors involved in the (e)MaaS ecosystem. The goal of this publication is to give an overview of the state of the art regarding (e)MaaS&rsquo ecosystems and architectures. Moreover, it aims to support the further development of eMaaS by proposing a definition and a novel system architecture for eMaaS. Firstly, the state of the art of the MaaS ecosystem is reviewed. Secondly, the eMaaS ecosystem that builds upon our definition of eMaaS is described and the MaaS system- and technical- architectures found in literature are reviewed. Finally, an eMaaS architecture that focuses on the integration of MaaS and electric mobility systems is presented. With the definition, ecosystem and system architecture presented in this work, the aim is to support the further development of the eMaaS concept. Document type: Articl
