Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng):Systems Engineering is a relatively new technical discipline and currently there is no generally accepted definition for it.
This thesis aims at decreasing the ambiguity around the topic by presenting different definitions of Systems Engineering, as well as systems as the objects of Systems Engineering.
As a synthesis, a definition of Systems Engineering is proposed; Systems Engineering is an iterative process that emphasizes customer/stakeholder needs and fulfilling the requirements and required functionalities of the system; includes need/requirement definition, design, realization, technical management, operations, and retirement; consists of a set of concepts, methodologies and organizational structures; and, concerns people, hardware, software, facilities, policies, processes, documents and naturally occurring entities.
Systems Engineering can be considered as model-based top-level product development in a broader sense; that is, concerning complex systems instead of only products and extending to the whole life-cycle of the system instead of only the development phase.

The thesis also presents three system design process models; one from Blanchard and Fabrycky, one from 1NCOSE, the International Council of Systems Engineering, and one from the ISO/IEC 15288 standard.
System design processes often emphasize the use of modelling and simulation; thus, a simple modelling-oriented early system design process model is proposed as a framework for the case study presented in the last part of the thesis.

Fulfilling the requirements of a system is one of the most critical aspects during the system design process.
Hence, different definitions of requirements are presented, and a classification of requirements during the system design process is proposed; in this work, system requirements are divided into functional/non-functional ones, and further into demands/wishes to support the latter phases of the system design.
The proposed classification is meant to be used inside the Early Development Process and Systems Engineering research group in Aalto University.

Finally, the requirements classification is also used in the case study in the thesis.
The requirements of the Eurobot 2010 robot competition were derived from the rules of the competition, and they were modelled using SysML.
The SysML model and the SysML profile that were developed during the case study serve as the starting point for further developments in the system modelling and design domain inside the research group.
