Agile software development (ASD) techniques are iteration based powerful methodologies to deliver high quality software. To ensure on time high quality software, the impact of factors affecting the development cycle should be evaluated constantly. Quick and precise factor evaluation results in better risk assessment, on time delivery and optimal use of(More)
One of the challenges in Risk Analysis and Management (RAM) is identifying the relationships between risk factors and risks. In this paper we propose using Extended Fuzzy Cognitive Maps to analyze the relationships between risk factors and risks. E-FCMs are suggested by Hagiwara to represent causal relationships more naturally. The main differences between(More)
This paper deals with the problem of the ranking of generalized fuzzy numbers. Our aim is to give a possibility to rank any non-identical generalized fuzzy numbers. The majority of existing approaches fail to rank fuzzy numbers in certain cases and give equality when in fact fuzzy numbers are different. We explore and extend Chen and Lu's approach that is(More)
Cognitive maps (CMs) were initially for graphical representation of uncertain causal reasoning. Later Kosko suggested Fuzzy Cognitive Maps (FCMs) in which users freely express their opinions in linguistic terms instead of crisp numbers. However, it is not always easy to assign some linguistic term to a causal link. In this paper we suggest a new type of CMs(More)
The use of expert systems can be helpful to improve the transparency and repeatability of assessments in areas of risk analysis with limited data available. In this field, human reliability analysis (HRA) is no exception, and, in particular, dependence analysis is an HRA task strongly based on analyst judgement. The analysis of dependence among Human(More)
Online games between remote opponents playing over computer networks are becoming a common activity of everyday life. However, computer interfaces for board games are usually based on the visual channel. For example, they require players to check their moves on a video display and interact by using pointing devices such as a mouse. Hence, they are not(More)
