Cost-effective maintenance of safety and security barriers in the chemical process industries via genetic algorithm

Chemical plants face safety hazards and security threats that may induce catastrophic scenarios. Safety and security barriers are employed widely to protect chemical plants from accidental and intentional undesired events and mitigate consequences. Managing safety and security barriers effectively and economically is a research topic with...

Dynamic-risk-informed safety barrier management: An application to cost-effective barrier optimization based on data from multiple sources

An integrated approach for performance assessment and management of safety barriers in a systemic manner is needed concerning the prevention and mitigation of major accidents in chemical process industries. Particularly, the effects of safety barriers on system risk reduction should be assessed in a dynamic manner to support the decision-making...

Economic and cost-effectiveness analysis of integrated desalination and brine treatment systems

The brine generated from desalination is a threat to the environment, and its disposal has been a great challenge. A new concept Zero liquid discharge (ZLD) can minimize the environmental impact of brine. However, the high costs for construction and running of a ZLD plant limits its growth in desalination market. Therefore, a new strategy...

Green Refits: Reducing yacht operational emissions through refitting

This research aims to determine the cost effectiveness of yacht emission reducing ret options through marginal abatement cost curves. A broad selection of five refit options is evaluated and implemented in the created tool. Using multiple scenarios by fluctuating fuel price and the implementation of hydrotreated vegetable oil (HVO), the effect...

Computational toolkit for early-stage cost assessment and optimisation of BIPV façades

Reduction of energy consumption and to increase its generation is necessary, as the population lives in urban settlements consume three-quarters of global resources, and these numbers are continually growing. Building-integrated photovoltaic panels (BIPV) which would assist for the resolution of the problem can be applied by replacing the façade...

Performance assessment of the Ocean Falls Wave Energy Converter: A solution for electrical power production in the future

There is a growing demand for renewable sources of energy of which wave energy conversion is one. The Ocean Falls is an oscillating water column (OWC) system invented by BAM Infraconsult b.v. This system differs from conventional OWC systems since it includes a connection tube and an adjustable back wall. The OWC system is a resonance system for...

Urban parcel delivery using lockers: Making last mile delivery more sustainable and cost efficient by using parcel lockers

Currently last mile parcel delivery is becoming more and more of an issue. More people are ordering their goods online, these goods need to be delivered to home address in urban areas. Using the parcel lockers of PostNL this research looked into the question how to make last mile logistics more cost efficient and sustainable using parcel lockers...

Cost-effectiveness of NGO-Sourced Health Franchising: Case of PSI Myanmar

Healthcare services in the developing countries are suffering from lack of equipment, expertise and infrastructure. Sexual reproductive health is one of these health areas in which the public health sector is not meeting the growing demand and it is defined as unmet need for family planning. To address this need, international agencies have been...
