Inspired 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...

To better govern inventory control of spare parts in tandem with scheduling of maintenance operations in a railway setting, a Railway Spare Inventory & Maintenance Scheduling (R-SIMS) model is developed. To suit the railway industry setting the model includes an inventory control strategy which envokes continuous monitoring and a reorder...

Fleet planning is a complex problem which consists of selecting an optimal fleet of vehicles at the right moment in time to serve a specific demand while subject to different operational constraints. While Operations Research (OR) has mainly focused on long-term strategical fleet planning optimisation, certain operators such as humanitarian air...

In this thesis, we consider investment optimization for airport infrastructure which is required charge and refuel electric and hydrogen powered aircraft using battery and hydrogen canister swaps respectively. The task at hand is to determine the most cost-effective infrastructure, consisting of spare batteries, and battery chargers for electric...

Condition-based maintenance (CBM) is emerging in the airline industry as a revolutionary concept that could potentially increase the efficiency of aircraft operations. The adoption of CBM strategies is not yet widespread due to the stringent requirements imposed by aviation authorities and the fact that the prognostic and health management (PHM)...

The buildup phase at KLM Cargo requires cumbersome planning actions because of a slow data handover at the warehouse and an uncertain initial state of the buildup process at the beginning of the shift. This study presents a model to improve scheduling of future buildup shifts according to flight departure times of KLM. The most important...

Railway systems occasionally get into a state of being out-of-control, meaning that barely any train is running, even though the required resources (infrastructure, rolling stock and crew) are available. Because of the large number of affected resources and the absence of detailed, timely and accurate information, currently existing...

When making a decision between conducting owner and contractor mining, it is common for the mine owner to take into consideration a number of factors to assess the suitability of either method for any particular project. This research identifies and investigates the key factors by means of literature review and questionnaires and interviews with...

The shipbuilding industry is not a standalone industry. It integrates with the shipping market, and therefore one characteristic of the shipbuilding industry is complexity. Competitiveness is a multi-dimensional concept that can be measured in numerous ways. The author found that these multi-dimensional concepts can better be translated into...

As one of the most important areas in the Palace Museum, Beijing, China, the Hall of Mental Cultivation had suffered from overcrowding of visitors before it was closed in 2016 for conservation. Preparing for the reopening in 2020, the Palace Museum decided to take the chance and initiate finer-grained tourism management in the Hall. This...

Water resources in the Ganges delta are undergoing drastic change as a result of urbanisation. Increasing demand for water due to urban expansion around cities like Kolkata (India) and Khulna (Bangladesh) is affecting groundwater access in nearby peri-urban communities. Peri-urban areas lie outside the formal purview of urban institutions, while...

This thesis introduces a new algorithm for optimising shipping routes within a dredging project. Highly dynamic and time-dependent hydrodynamic features influence shipping routes. Due to the complex interactions between the horizontal tide, vertical tide, stratifying forces, wind-driven forces, and limited water-depth, shipping routes were...

This thesis discusses the connection between container terminals and the hinterland railway system. Mathematical models are proposed to formulate the various relevant operations and methods are developed to provide solutions to improve the system performance. This thesis could provide suggestions to decision maker(s) regarding to the improvement...

To convey the energy coming from offshore wind-farms to the end-users, a network of offshore transmission platforms with sub-sea cables is in place, functioning as the supply chain for electricity. This research addresses the development of an optimization model, OptiFleet, which targets the problem of vessel fleet management to perform the...

A strategy for completing a dredging project is called a working method. The goal of a tender study is to find an optimal working method for a specific project. To find the optimal working method, the full range of possible solutions should be investigated. However, the available resources during a tender study are often limited and trends in...

Railway systems occasionally get into a state of out-of-control, meaning that there is barely any train is running, even though the required resources (infrastructure, rolling stock and crew) are available. These situations can either be caused by large disruptions or unexpected propagation and accumulation of delays. Because of the large number...

One of the most important health care services is emergency medical service as it plays a vital role in saving people's lives and reducing the rate of mortality and morbidity. Over the last years, many review papers have discussed emergency medical services (EMS) location problems, however, only few review papers consider the full range of EMS...

Abstract: The operations of KLM Cityhopper (KLC) is a complex undertaking. Many safety, statutory and contractual rules and agreements need to be considered for managing its operations. Hence, KLC spends considerable time, effort and money on planning its resources carefully. Unfortunately, it is all too common that unforeseen events during the...

As of yet, there are virtually no practical tools available for incorporating both developer and consumer preferences within a floorplan design. This study aims to deliver a proof of concept for such preference-based design systems, and their application within the commercial property development process. A research model is presented that is...
