Exploring and expanding GSE education with open source software development
No full textGlobal software engineering (GSE) courses traditionally require cooperation between at least two universities so as to provide a distributed development environment to the students. In this study, we explore an alternative way to organize a global software engineering course where students work on open source software development (OSSD) projects rather than in a multi-university collaboration setting. The results show that the new setup may provide core GSE challenges as well as challenges associated with software development outsourcing and challenges related to working on large open source software. The present article compares the experiences gained from running a combined GSE and OSSD course against the experiences gained from running a traditional GSE course. The two alternatives are compared in terms of students’ learning outcomes and course organization. The authors found that a combined GSE and OSSD course provides learning opportunities that are partly overlapping with, and partly complementary to, a traditional GSE course. The authors also found that the combined OSSD and GSE course was somewhat easier to organize because most of the activities took place in a single university setting. The authors used the extended GSE taxonomy for the comparison and found it to be a useful tool for this, although it had some limitations in expressive power. Therefore, two additional relationship dimensions are proposed that will further enrich the extended taxonomy in classifying GSE (and OSSD) projects.publishedVersion© 2019 Copyright held by the owner/author(s).

Electric Ground Support Equipment at Airports: The impact of implementing eGSE on the capacity and demand of GSE fleets
No full textAirports and airlines are examining and committing to the electrification of Ground Support Equipment (GSE). To be able to estimate the required quantity of eGSE, the charging requirements of eGSE, the change of airport electricity requirements, and the scheduling possibilities of eGSE charging for the existing turnaround procedures, a model was developed to simulate and optimize the GSE operations at airports. This was done by means of a Task Scheduling Problem (TSP), that is optimized using Mixed-Integer Linear Programming (MILP). A case study was performed on KLM's GSE fleet at Amsterdam Airport Schiphol. Based on this, it was concluded that there is no difference in the capacity that can be achieved for GSE types that can last an entire day on a single battery charge. However, another group of GSE types experiences battery depletion before the day concludes, requiring measures to maintain the capacity. The results indicate the model's suitability for strategic decision-making. Next to that, the model is effective on an operational level. The use of the model has the potential to make the use of resources in the operation more efficient.Mechanical Engineering | Multi-Machine Engineerin

Requirements Engineering Practices in Global Software Engineering Organizations: A Study in the Banking Industry
No full textIn this thesis we report on our investigation of requirements engineering (RE) practices and challenges in global software engineering (GSE) settings. We conducted a literature survey and a series of interviews/surveys to reach our goal. The subject of the research is the banking industry in the Netherlands actively involved in GSE. More specifically, the goal of this research is to find out what banking organizations have learned from RE practices when used in GSE settings. Specifically, the project investigates how GSE teams handle RE problems especially in the beginning of a project and attempts to identify the solutions in used in practice to deal with such challenges. The overall conclusions are that the use of liaison officers, the use of the online collaboration tools, and the use of a transparent RE process are the common practices that are used by the banks in the Netherlands to overcome their RE challenges in GSE project settings.Information ArchitectureComputer ScienceElectrical Engineering, Mathematics and Computer Scienc
An annotated catalogue of selected works for clarinet by South African composers
No full textThe dissertation consists of an annotated catalogue of nineteen selected works for clarinet by South African composers. These are presented in chronological order, based on the year of composition. A short biographyof the composer is given before the work is discussed. Of the analysed works, all those for solo clarinet or for clarinet and piano have been graded. A thesis of a similar nature, written in 1989 by L.A. Hartshorne, entitled ""The Compositions for Clarinet by South African Composers"", contains details of twenty-four works written between 1928 and circa 1981. The majority of the compositions analysed in the current dissertation were written from around 1981 onwards, and to some extent, therefore, this research could be seen as complementary to the information contained in the aforementioned thesis. An addendum lists all the South African works featuring solo clarinet that the author was able to trace. These include solo works, cham ber works for up to nineteen instruments and concerto-type works with strings or orchestra
Multi-agent planning and coordination for automated aircraft ground handling
No full textInspired by the vision of fully autonomous airside operations at Schiphol airport, this study aims to contribute to the short-term goal of automated aircraft ground handling. In this research, we design and evaluate a multi-agent system for planning of automated ground handling. There are two main components in the system: task allocation optimization and multi-agent path planning. To allocate tasks to ground support equipment (GSE) vehicles, an auction mechanism inspired by temporal sequential single item (TeSSI) auction is proposed. Ground handling tasks scheduling for GSE vehicles is modeled as several single-vehicle pickup and delivery optimization problems (SPDP), and the values of the objective functions are used to generate bids for GSE vehicle agents in the auction. Prioritized safe interval path planning for large agents (LA-SIPP) is used to plan collision-free paths for GSE vehicle agents in the model to execute tasks. The aim is to increase the success rates of allocating tasks and finding collision free paths without causing flight delays, given the limited resources such as a small number of available GSE vehicles, time windows constraints and conflicting interests of different agents. Due to the results, even for the instances with frequent flights and the most limited resources, the success rates of allocation and path planning were higher than 81% and 98%, respectively. Furthermore, periodic task allocation and path planning of the ground handling tasks for flights in three aircraft stands during a planning time window of the day, as well as replanning in case of disruptions were performed in a short CPU time. There is a lack of research dealing with the complete process of ground handling, since existing studies concerning the automation of ground handling operations involve fleet assignment or task scheduling models without an integration of detailed path planning. Our main contribution is to present a framework that combines task allocation and path planning for automation of ground handling operations and provides solutions using a multi-agent perspective.Air Transport & Operation

Experimental studies have shown that the system is able to perform task allocation and path planning of ground handling tasks for flights in 3 aircraft stands within a 4-hour time in a reasonable computational time. Moreover, the model is capable to replan the tasks for agents when disruption happens. Applying the lowest possible numbers of vehicles used in the current operation, the model can always reach success allocation and path planning rates higher than 81% and 98%, respectively.Aerospace Engineerin
Design of an Airport Service Infrastructure for Sustainable Refueling of Aircraft: Model Development for the Quantification of CO2e Emissions, Total Cost of Ownership and Grid Load Effects of Electrified Refueler Fleets at Future Airports
No full textGround Support Equipment (GSE) fleets must be made more sustainable to contribute to the achievement of emission stabilisation and reduction goals for a growing aviation sector. Electrification of GSE offers great opportunities to mitigate greenhouse gas emissions, thereby increasing sustainability. This research focuses on how to design an airport service infrastructure for sustainable refueling of aircraft using electric refuelers. Although important for the design of such infrastructure, current literature fails to investigate potential emission reduction as a result of implementing electric GSE in mixed fleets with conventionally fueled GSE. Therefore, this work presents the development of a capacity model that quantifies the performance of sustainable refueling service infrastructures, consisting of partially (or fully) electrified fleets and charging points, in terms of annual CO2e emissions. Using future flight schedules as input, this algorithm models the activity of electrified refueler fleets taking charging downtime and forecasted airport growth into account. Model outputs provide insights in future fleet size, fleet mix and charging infrastructure requirements on a tactical level to achieve carbon emission goals for refueler fleets on a strategic level. As capital investments have to be made to electrify refueler fleets, the effect on the Total Cost of Ownership for ground handlers is investigated as well. The entire model functions as an essential input for future airport design related to aircraft services.Mechanical Engineerin
