Abstract Maritime Autonomous Surface Ships (MASS) are attracting increasing attention in the maritime industry. Despite expected benefits reducing human error and significantly overall safety level, development of autonomous ships would undoubtedly introduce new risks. The goal this work is to develop an approach evaluate risk level major hazards associated with MASS. To that extent, a Failure ...

Abstract Safe storage of radioactive materials is based on three universal radiation protection principles. Justification, optimization and dose limits are applicable to the risk assessment, acknowledging hazards in each procedure delivery, usage, disposal materials. Failure Modes Effects Analysis method (FMEA) developed for evaluation common practices. In this work FMEA exploited radiological ...

The quality of midsole products significantly impacts the quality, durability, and comfort users shoe manufactured by ABC company. high percentage average number product defects based on yield data for 12 months is 3.1% which exceeds required company 2%. There are six types in midsole: yellowing, porous, bubbles, broken, over left material trimming. Three from focus improvement Pareto concept, ...

The growing importance of on-board diagnosis for automobiles demands for new diagnostic methodologies and techniques and for a close integration of diagnostic tasks in the entire design process. This report describes work carried out within two European projects. In the "Vehicle Model based Diagnosis" (VMBD) project, demonstrator vehicles with built-in faults provided a serious challenge to mod...

Fault Tree Analysis (FTA) has become a popular tool for use in the Space Industry for the System Safety Engineer. The fault tree is used for everything from tracking hazard reports to investigating accidents, as well as presentations to management. Yet, experience in the space industry has shown the fault tree is used most often for purposes other than its original intent, namely for evaluating...

Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...

Time pressure and quality issues bring new challenges for developing web-based systems. The ability to analyze quality early in the development lifecycle is crucial. Among the techniques suggested by the literature, few of them actually support early quality activities when little information about the system is available. We take robustness as a critically important quality attribute, and pres...

A dam construction project is exposed to various risks due the amount of investment, duration implementation, complexity design and etc., these will lead human financial losses. Thus, based on three principles, including (i) time, (ii) quality, (iii) cost, identifying, assessing, ranking risks, Occupational Safety Health (OSH) can have a significant impact objectives. The machinery maintenance ...

Fault diagnosis and prognosis methods are the most useful tools for risk reliability analysis in food processing systems. Proactive techniques such as failure mode effect (FMEA) important detecting all probable failures facilitating process. However, significant uncertainties exist classical-FMEA when it comes to ranking priority numbers (RPNs) of modes. Such may have an impact on sector’s oper...
