Automated Guided Vehicles (AGVs) are being increasingly used for intelligent transportation and distribution of materials in warehouses and auto-production lines. In this paper, a preliminary hazard analysis of an AGV’s critical components is conducted by the approach of Failure Modes Effects and Criticality Analysis (FMECA). To implement this research, a particular AGV transport system is mode...

The paper presents work in progress aiming at extending Failure-modes-and-effects Analysis (FMEA) to include embedded software. It is based on the insight that requirements on Software FMEA in this context are only dependent on the required functionality of the physical system, which, in particular, allows the consideration of a finite set of qualitatively characterized software failures.

This paper proposes an integrated approach to identify, evaluate, and improve the potential failures in a service setting. This integrated approach combines FCS-FMEA, GRA and profitability theory for better prioritization of the service failures by considering cost as an important issue and using the profitability theory in a way that the corrective actions costs are taken into account. Conside...

Failure mode and effects analysis (FMEA) has been proven to be an effective methodology to improve system design reliability. However, the standard approach reveals some weaknesses when applied to wind turbine systems. The conventional criticality assessment method has been criticized as having many limitations such as the weighting of severity and detection factors. In this paper, we aim to ov...

This paper presents a ‘Lexicographic’ Goal Programming (LGP) approach to define the best strategies for the maintenance of critical centrifugal pumps in an oil refinery. For each pump failure mode, the model allows to take into account the maintenance policy burden in terms of inspection or repair and in terms of the manpower involved, linking them to efficiency-risk aspects quantified as in FM...

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 new method of diagnosing risks in product-innovation projects is introduced in the paper. The method is an improvement on existing risk methods used on product-innovation projects, such as potential problem analysis and failure mode and effects analysis. Technological, organizational and commercial risks are identified and assessed on an individual basis. These risks are mapped in a risk topo...

This study focuses on building a framework which calculates the weights of FAHP (Fuzzy Analytical Hierarchical Process) method , then integrates the analysis tools such as FQFD (Fuzzy Quality Function Development) and FFMEA (Fuzzy Failure Mode and Effects Analysis) into the framework to construct a two-phase product specifications evaluation process. Therefore, this study builds a framework and...

Preventive methods are seldom used in logistics, although there is increasing awareness of their potential. This paper presents two examples of preventive methods currently in use, Poka-Yoke and FMEA (Failure Mode and Effect Analysis). The implementation of Poka-Yoke, the mistake proofing methodology, has been shown to drastically reduce the enormous warranty costs, including logistics costs, w...
