Digitalisation and Industry 4.0 have enabled real-time interaction of customers and suppliers with manufacturing systems. However, this requires a high level of reactivity in the value chain to sustain in a competitive economy. As a result, Quick Response Manufacturing (QRM) in dynamic conditions such as wide product variety, change in demand, vola...

Background: Clinical heterogeneity was observed among COVID-19 patients with acute respiratory distress syndrome (CARDS). The heterogeneity of disease was contributed to different clinical progression, responses to treatment, and mortality. Objective: We aim to study the phenotype and associated mortality of COVID-19 respiratory failure in Thai pat...

Previous researchers have made impressive strides in developing algorithms and solution methodologies to address multi-objective optimization (MOO) problems in industrial engineering and associated fields. One traditional approach is to determine a Pareto optimal set that represents the trade-off between objectives. However, this approach could res...

Budget allocation problems in portfolio management are inherently multi-objective as they entail different types of assets of which performance metrics are not directly comparable. Existing asset management methods that either consolidate multiple goals to form a single objective (a priori) or populate a Pareto optimal set (a posteriori) may not be...

Among the reliability engineering and asset management problems addressed in the literature, those pertaining to multi-unit systems have particularly intrigued researchers because of their profound effects on the organisational performance. Despite impressive strides made in improving maintenance planning for assets of a single type, only a paucity...

Devising a long-term maintenance plan for a system of large infrastructure assets is an exacting task. Any maintenance activity that induces system downtime can incur a massive production or service loss. This problem becomes increasingly challenging for a system of which the performance is based on the collective output of assets. Current approach...

This article gives an overview of the literature on asset management for multi-unit systems with an emphasis on two multi-asset categories: fleet (a system of homogeneous assets) and portfolio (a system of heterogeneous assets). As asset systems become more complicated, researchers have employed different terms to refer to their specific problems....

Large infrastructure assets commonly require high intervention costs, but the absence of an effective asset management plan can bring about a massive production loss for a company. Hence, managing these assets is considered a daunting task and is even more complicated if these assets operate collectively to produce an output. This paper explores a...
