Project management has been consolidated into organizations due to its high added value, allowing that project results are delivered on time, budget, scope and quality. This is specially important for ICT projects, for which innovation is usually present. For such, the correct resource allocation, and effective management require application of project management techniques and tools. In this s...

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...

In this paper we overview the achievement of the IDD European projects, which aims at defining a new framework for design of automotive systems. In particular, starting from the weakness of the current design process, especially as regards issues related to diagnosis (diagnosability analysis, generation of the FMEA – Failure Mode Effect Analysis, generation of on-board diagnostic rule), the pro...

The paper describes recent work to improve the safety process for aero-engine controllers. The role of FMEA is discussed in the context of the safety and certification processes, with reference to ARP 4754 and ARP 4761. Whilst the ARPs' emphasis on top-down hazard-driven approaches is valuable, it is concluded that the role of FMEA should not be down-played. Instead it should be recognized that...

Building modern aerospace systems is highly demanding. They should be extremely dependable. They must offer service without interruption (i.e., without failure) for a very long time — typically years or decades. Whereas ”five nines” dependability, i.e., a 99.999 % availability, is satisfactory for most safety-critical systems, for on-board systems it is not. Faults are costly and may severly da...

Software development is a complex process and begins with requirement gathering. Requirements are specified in their natural forms and are required to be converted into formal specifications such as object diagram for further use in any software development process. These diagrams are useful for clearly understanding the problem definition of software and other documentation purpose. This paper...

As software becomes more complicated and larger, software engineer’s requirements analysis become important and uneasy activity. This paper proposes a requirements analysis supporting system that supports informal requirements analysis. The proposed system measures the similarity between requirement sentences to identify possible redundancies and inconsistencies, and extracts the possible ambig...
