van den Brink, Luc (author)This paper investigates the optimisation of Automated Storage and Retrieval Systems (AS/RS) in warehousing by minimising performance losses during partial downtime. Given the increasing automation in logistics, AS/RS systems play a pivotal role, yet the operation of those systems during partial downtime remains a topic ignored in literature....master thesis 2024

Rouwé, Machteld (author)Offshore wind energy can play a key role in the energy transition. Reducing installation costs for offshore wind installation projects helps to be cost-competitive with other renewable energy technologies. Installation costs can increase when the installation project planning is delayed. Literature shows that offshore wind installation projects...master thesis 2023

Iuliis, Melissa De (author), Kammouh, O. (author), Cimellaro, Gian Paolo (author), Tesfamariam, Solomon (author)Natural and human-made disasters can disrupt infrastructures even if they are designed to be hazard resistant. While the occurrence of hazards can only be predicted to some extent, their impact can be managed by increasing the emergency response and reducing the vulnerability of infrastructure. In the context of risk management, the ability of...journal article 2021

De Iuliis, Melissa (author), Kammouh, O. (author), Cimellaro, Gian Paolo (author), Tesfamariam, Solomon (author)Critical infrastructures are an integral part of our society and economy. Services like gas supply or water networks are expected to be available at all times since a service failure may incur catastrophic consequences to the public health, safety, and financial capacity of the society. Several resilience strategies have been examined to...journal article 2021

Wiegel, M.F. (author), de Boer, W.P. (author), van Koningsveld, M. (author), van der Hout, A.J. (author), Reniers, A.J.H.M. (author)Seaport operability is key to the economic viability of ports. Metocean conditions (e.g., wind, short waves, and infragravity waves) affect this operability when certain thresholds are exceeded. This paper describes a method for the global mapping of seaport operability risk indicators using open-source metocean data. This global-scale...journal article 2021

Woerlee, Sebastiaan (author)Nowadays, conceptual breakwater layout design mostly relies on experience and expert judgement, making it complicated to demonstrate that an economic optimum has been reached. This stresses the need to develop a tool that is able to establish the economically most attractive breakwater layout for a certain set of requirements and site-specific...master thesis 2019

Bruijn, Willem E.L. (author), Rip, Jolien (author), Hendriks, Antoon J.H. (author), van Gelder, P.H.A.J.M. (author), Jonkman, Sebastiaan N. (author)A marine project consists of series of operations, with each operation subject to a predefined operational limit and duration. If actual weather conditions exceed the operational limit, the operation cannot be executed and hence downtime occurs. An accurate assessment of uncertainties and the expected downtime during a marine project is...journal article 2019

Bruijn, Willem (author)A complex marine project consist of series of operations, with each operation subject to a predefined operational limit and duration, depending on the equipment being used. If actual weather conditions exceed the operational limit, then the operation cannot be executed and hence downtime occurs. It is up to contractors, such as Boskalis, to...master thesis 2017

Boom, Marco (author), Groenenboom, Max (author), van Dijk, Onne (author), Wooning, Joost (author)ProRail uses multiple custom built software applications to control the train infrastructure in the Netherlands. At this moment these applications experience downtime when they are updated. This interrupts processes that are related to controlling the train services. ProRail asked us to redesign an existing application in such a way that updates...bachelor thesis 2017

Dhanisetty, V.S.V. (author), Verhagen, W.J.C. (author), Curran, R. (author)Decision making in daily maintenance requires consideration of multiple factors. The importance of each of the factors fluctuates depending on the repair scenario and the needs of the maintainer. In order to include the prioritisation of multiple criteria, a weighted decision making model is developed. The model evaluates all repair options and...conference paper 2017

Groenenberg, X. (author)The objective of this study is to determine whether a floating terminal could be a suitable and feasible solution for the realisation of a new berthing location for the cruise ships of the future. This feasibility study is based on the amount of downtime of a terminal due to excessive motions because of wave loading. Therefore, this study...master thesis 2016

Rip, J. (author)A marine operations encounters downtime if its operational limit is exceeded during project execution. Accurate information about the expected downtime during a marine project is important information in the tender phase of such a project. The purpose of this thesis is therefore to give insight in the available methods for downtime analysis in...master thesis 2015

De Jong, M. (author)When a web service or application evolves, its database schema --- tables, constraints, and indices --- often need to evolve along with it. Depending on the database, some of these changes require a full table lock, preventing the service from accessing the tables under change. To deal with this, web services are typically taken offline...master thesis 2015

De Pee, A. (author)This document focuses on the weather downtime in the offloading cycle of a generic LNG Floating Storage and Regasification Unit (FSRU). Results from these weather downtime assessments are essential for site concept selection and design of FSRU's, and are also used as input for logistics simulating the total gas supply chain. The FSRU is an...master thesis 2005

Veen, E.J. (author)The downtime of a jetty terminal is one of the key factors in the planning and design of the onshore facilities. Long waiting times (downtime) due to restricting environmental conditions should be avoided. During the first design phase of a berth for Liquefied Natural Gas carriers many alternatives are open but no detailed calculations have yet...master thesis 2003
