Hybrids vehicles have a long history and a promising future and Belgium is part of it. They have a very large variety of architectures and technical options. Each one with very different results depending not only the physical disposition but also the energy management policy. The characteristics of different architectures and its specificities have been studied in this work, focusing in the series-parallel configuration known as AutoMixte.
Buses, as a particular kind of vehicle, have specific requirements. The utilization of hybrid powertrains in buses is a very interesting way to reduce the pollution and the congestion in the cities at the same time, with very low investments in infrastructure and reducing the fuel consumption and the fuel-dependency of the town.
Planetary gears are widely used in vehicles. In addition to the differential gear, they are one of the main components of automatic gearboxes, accumulating key advantages like longer life span and higher compactness for relatively higher ratios. The design established the optimum speed ratio as an adaptation of the speed range of the power machines to the bus speed range. The complete design respected particular compatibility rules and verified the loaded resistance using commercial software and classic formulas from international standards.
The integration of the planetary gears was modelled in a global system model with all the powertrain elements in order to obtain the total maximum mechanical output of the bus. The verification of the performance of the vehicle includes a gradeability and an acceleration simulation.
This work ends with the simulation of the consumption of this powertrain in the bus assuming one particular energy management policy and the standardised test for buses know as SORT. The efficiencies of the electrical machines were taken into account as well as the charging and discharging efficiencies of the battery. Specific consumption maps of the engine were used to calculate the fuel consumption of the bus.

The purpose of this dissertation is to bring forward patterns and links between social innovations that are active in the fight against homelessness. Homelessness in general is a growing phenomenon, and classic responses do not seem to be sufficient. The innovativeness of the projects is therefore defined in this study as the dissimilarity of approach to these classic responses. By analysing twenty-four existing social innovation projects and the promise of the impact they are creating, this dissertation aims to create a better understanding of how social innovation takes place in this specific field and to write recommendations for the actors that are present in it such as researchers, entrepreneurs and governments.
The methodology used, relies on social performance analysis and more specifically on the change theory model. The participating projects were identified through online search engines, online platforms that regroup Belgian non-profits and the “Housing Solutions Platform” and selected by their innovativeness and diversity. Afterwards, they were examined through the optic of the change theory model. Then, comparisons within segments of that model and new models linking elements of different of those segments were constructed. Of course, at the beginning of the dissertation a literature review on homelessness, social innovation and social performance analysis was executed to create a background on these topics and allow for a better understanding of the analysed projects and used methods.
This explorative study resulted in interesting observations about social innovations in the field of homelessness, opened up questions about them that could be the basis of future quantitative research or qualitative interviews with such projects, and formulated recommendations and conclusions for researchers, for entrepreneurs, for aspiring entrepreneurs and for governments.

In an increasingly fast-moving automotive market, it is essential for car dealers to anticipate future consumer behaviour. In order to beat competitors, swift action is required. For this purpose, the management team of Discar Liège wishes to develop its control system by choosing the appropriate performance indicators, which will be decisive in order to make the right decisions. 
In this paper, the different steps followed to obtain a dashboard tree and efficient KPIs are described. Firstly, the control process and indicators currently in use are analysed. Secondly, the stakeholders’ needs and the causes of existing issues in terms of data representativeness are detected. Then, research is carried out in order to develop a control system and dashboards adapted to dealership and automotive world specificities. 
At the end of the study, recommendations to address existing problems are made. A process for producing and delivering dashboards, tailored to the current situation, is also suggested. Lastly, dashboard templates are proposed. 
The suggested KPIs should allow an early detection of the sector developments but must be continuously reviewed in order to be perfectly aligned with the Discar Group’s strategy.
