Recent regulatory requirements for shipping emissions control have led to the adoption of Liquefied Natural Gas (LNG) as a marine fuel and design LNG-fuelled vessels. Considering potential safety implications due system failure/unavailability, this study aims at analysis low-pressure LNG feeding using novel model-based methodology. The proposed methodology is based on functional modelling, lead...

Fault tree analysis (FTA) is one of the most popular failure techniques that reveal potential pathways leading to systems or components failure. It has been widely employed in numerous sectors understand how a system fails and improved. However, conventional FTA criticized due series inherent shortcomings state arts. Accordingly, scholars, engineers, practitioners made their attempts improve by...

This article presents the case that fault tree analysis is the better risk analysis method to apply early in software development projects.

This work deals with the determination of inadequacies/pitfalls in quantifying air pollution impacts. Firstly, the critical pollutant concentration Pcr is determined as the equilibrium point in the tradeoff between indirect environmental (due to impact at societal level) and direct economic (for pollutant abatement) cost. It is proved that certain exogenous factors may intervene in estimating t...

In wireless sensor networks, the node faults often occurred in scenes because of severe disturbance, harsh environment and inherent weakness of the networks. In this paper, a fault tolerance directed diffusion protocol, termed fault-tolerant algorithm with recoverable nodes (FTA-RN), is proposed to extend the lifetime of the wireless sensor network based on recoverable host nodes, in which a he...

Functional safety analysis (FSA), that is checking whether a designed artifact will perform safely even under the presence of failing components, has gained significant importance in different areas, including aeronautic and automotive systems. The same applies to failure-modes-and-effects analysis (FMEA) and fault-tree analysis (FTA) as the major contributing processes. FSA is laborand time-co...

CV. XYZ is a company engaged in the production of wood into finished goods (furniture), one which wooden chairs. In process making chairs, various types damaged products such as broken, painted (varnished), scuffed, and loose are still found. This study aims to analyze quality control provide suggestions for improvement reduce product defects, using Statistical Quality Control (SQC) method with...

There are four primary accident types at steel building construction (SC) projects: falls (tumbles), object falls, object collapse, and electrocution. Several systematic safety risk assessment approaches, such as fault tree analysis (FTA) and failure mode and effect criticality analysis (FMECA), have been used to evaluate safety risks at SC projects. However, these traditional methods ineffecti...

Design is divided primarily into two processes: ‘synthesis’ and ‘analysis’. For the purposes of this paper, synthesis is regarded as the process of decision-making regarding parameters, and analysis as the process of optimizing those parameters. It is known from experience that the mistakes made during the synthesis process are never completely corrected in the analysis process. For example, in...
