Development and experimental testing of a collaborative design rationale method for early-stage ship layout design

Design rationale is a promising way of capturing design decisions and considerations for later retrieval and traceability to improve collaborative design decision-making. To achieve these perceived benefits for early-stage complex ship design, this paper first elaborates on the development of a proof-of-concept design rationale method. The...

Sustainable product-package design in a food supply chain: A multi-criteria life cycle approach

This paper presents a multi-criteria decision-making approach for the selection of a sustainable product-package design, accounting for the different actors within a food supply chain. The study extends the focus of sustainable packaging design to the collective of all supply chain actors. Decision criteria are identified via a literature...

Forecasting design and decision paths in ship design using the ship-centric Markov decision process model

A Monte Carlo approach to the ship-centric Markov decision process for analyzing decisions over converting a containership to LNG power

A Monte Carlo approach to the ship-centric Markov decision process (SC-MDP) is presented for analyzing whether a container ship should convert to LNG power in the face of evolving Emission Control Area regulations. The SC-MDP model was originally developed as a means to analyze uncertain, sequential decision making problems. However, the...

A ship egress analysis method using spectral Markov decision processes

A decision-making framework for planning lifecycle ballast water treatment compliance

A ship egress analysis method using spectral Markov decision processes

A decision-making framework for planning lifecycle ballast water treatment compliance

This paper introduces a novel decision-making framework for planning lifecycle compliance of ballast water treatment by applying eigenvalue spectral analysis<br/>to the ship-centric Markov decision process (SC-MDP) framework. This method focuses on identifying the relationships of various decision making scenarios, and how those relationships...

A ship egress analysis method using spectral Markov decision processes

This paper introduces a means of performing a ship egress analysis by applying eigenvalue analysis to the ship-centric Markov decision process (SC-MDP) framework. This method focuses on how people egress, the decisions they make under uncertainty, and the interaction between the individuals and the layout of the vessel. The objective is to...
