The System of Circular Material Hubs in the Netherlands: An exploratory research on practices performed within the system of circular material hubs in the Netherlands: its challenges, opportunities, potential future developments and the connection to architects

<b>Purpose:</b> The construction industry is responsible for great amounts of resource consumption, waste generation and both carbon and greenhouse gas emissions in the European Union. The currently still predominant linear mindset of take-make-consume-dispose must shift to reduce the industry’s environmental impact and enable the transition...

Strategic Development for the Port of St. Eustatius: A Study on the Potential Role of Privatisation

This paper examines the potential for privatising the port of St. Eustatius to achieve self-sustainability through the strategic port planning process. Design criteria were established based on a PESTEL, SWOT, and trend analysis, resulting in the development of four strategies. These strategies include enhancing port resilience, creating a...

Circular Ship Design: Defining a Framework for Implementing the Circular Economy Principles into Ship Design

Ensuring sustainability in shipping extends beyond fuel choices to encompass the responsible use of materials in vessel construction and maintenance. Shifting from the prevailing 'take-make-dispose' model to a circular economy is crucial for enhancing sustainable waste reduction in the industry. Unlike consumer goods, current ship design...

Scheduling Multi-Vessel Placement in Multi-Chamber Inland Waterway Locks Using Switching Max-Plus Algebra

Inland waterway transport is a low CO2 emission alternative to road transport. A shift towards more inland waterway transport could also help reduce road congestion and noise pollution. Infrastructure bottlenecking, particularly at locks, is part of the reasons preventing this shift. Congestion is leading to delays. Locks can be physically...

Power & Free Conveyor Operation at the SEW Eurodrive Assembly Plant in a Cyber-Physical Production System Perspective

This master thesis focuses on the effect of variabilities in a Power &amp; Free conveyor system on the flow continuity by an analysis on the product, process and production level (3P), a discrete-event simulation model and the theory of Cyber-Physical Production systems (CPPS) to control the product flow. Scenarios were evaluated with this model...

The Design of a ’Water Droplet’-Based UFP Mitigation System at Airports: A Case Study at Amsterdam Airport Schiphol

This research explored potential designs of an innovative mitigation strategy to combat the aircraft-produced ultrafine particle (UFP) concentrations at Amsterdam Airport Schiphol (AMS). This technique is based on the principle that fine water droplets are able to encapsulate dust and fine particles, which clump together and eventually descent...

Optimising quay crane operations based on data-driven cycle time prediction: A case study at APM Terminals MVII

Quay cranes on modern container terminals have the possibility to lift two 40ft. containers side by side. In order to be able to perform this type of lift, the crane must be equipped with a tandem spreader. As this type of spreader cannot be used for performing certain lifts, such as the handling of hatch covers, switches between single spreader...

Measuring the environmental performance of the feed production of the livestock industry: Constructing an environmental performance index from an economic perspective

Abstract<br/>Purpose - The aim of this paper is to propose a method for performance measurement of the livestock feed industry from an environmental and economic perspective. There is a knowledge gap both in the literature and society in the field of performance measurement of the livestock feed industry with environmental concerns. Livestock...

Designing a bottom-up Remanufacturing Process Control and Maturity Model for Airline MRO: A case study at KLM E&M

In this day and age sustainability is becoming increasingly important. Even though the airline business is not the first thing which comes to mind when regarding sustainability there are huge efforts in play to extend the life of airplanes and its corresponding components. This is done via remanufacturing. Remanufacturing can here be defined as:...

Managing Car Traffic by (Smart) Mobility Hubs: Towards effective policy making

There is an ongoing trend of urbanisation, and cities are becoming more and more crowded. In 2014, 46\% of the population of the OECD countries lived in urban areas. Whereas the growth of cities was previously mainly an expansion, the growing population is now increasingly leading to densification. Since 2007, more than half of the constructed...

Once in a (technical) lifetime: Assessing the influence of interdependence and climate change uncertainty on the decision-making process for the renewal of hydraulic infrastructure. A case study at Zoutkamp.

In order to keep the hydraulic infrastructure system in the Netherlands from deteriorating, large investments will have to be done in the near future. Decision-support frameworks help in making the right investment decisions for infrastructure that is intended to stand for a hundred years. Such a long lifetime brings forth a high level of...

Data-Driven Transportation Planning for a Large Manufacturing Plant: Analysis and development of a planning support tool for the internal transportation at Tata Steel IJmuiden

Planning the on-site transportation of large manufacturing sites is a complex process. Currently these plans are made based on the on-site logistics constraints rather than on KPIs. Research has been focused on either analysis of system parameters or generally on KPIs, but lacks the combination of both on real-life cases. This gap is closed by...

A-pier Clean VOP: Developing a strategy for on-time cargo delivery to the aircraft under clean apron conditions

The introduction of MARS stands at Amsterdam Airport Schiphol’s new A-pier means a Clean VOP policy will be enforced. Under this regulation, vacant aircraft stands must be free of any cargo and baggage. In order to comply with this policy, KLM Cargo has to redesign its cargo handling procedure which is currently based on push logic. This paper...

Design of an Advanced Task Planning Model for Aircraft Heavy Maintenance: A case study at KLM Engineering & Maintenance Airframe Services

Due to complex nature of aircraft heavy maintenance checks, achieving process stability is difficult. Literature suggests that this stability can be obtained by separating routine and non-routine work, and focusing on quick identification of non-routine tasks by completing inspection tasks early in the check. Current task planning methods show...

Redesign of Airframe MRO processes from an uptime perspective: a case study at KLM Engineering and Maintenance Airframe Services

This thesis addresses a problem at KLM E&amp;M, where a gap exist between the desired performance and current performance of airframe MRO. This research is performed to find solutions within the A-check for wide body aircraft by identifying the constraint in the A-check and subsequently develop solution alternatives by first exploiting the...
