“…Thereafter, numerous HRA approaches started to evolve in order to assess human error and reliability such as THERP (Technique for Human Error Rate Prediction). The method is hybrid and it combines the dependency and recovery (Swain, 1963). The purpose of the paper is to evaluate human reliability dealing with task analysis, failure definition and quantification of HEP values.…”

More than 80% of international cargo moves through seaports, making a contribution to the world economy. As a result, the performance of seafarers plays a major role in the safety of international trade and the maritime environment. This paper presents a novel approach to monitoring the performance of seafarers in terms of their conditional reliability. Unlike a traditional reliability analysis of a seafarer, this approach contains a dynamic model capable of coping with continually changing conditions that affect a seafarer's performance. The proposed methodology enables and facilitates decision makers to assess the performance of a seafarer before his or her designation to any activities and during his or her seafaring period. To evaluate a seafarer's reliability, a generic model is constructed and a combination of different techniques such as fuzzy logic, a fuzzy rule base, an analytical hierarchy process, evidential reasoning, a mapping process and expected utility is used. Furthermore, by changing the conditions that affect the reliability of an ideal seafarer and through calculating a value for this reliability, a benchmark is constructed. A seafarer's reliability depends upon many variables and their dependencies; alteration of a criterion value will ultimately alter a seafarer's reliability. In order to correct any deviation on time, a seafarer's reliability has to be measured appropriately and regularly.

A Laboratory-Directed Research and Development project was initiated in 2005 to investigate Human Performance Modeling in a System of Systems analytic environment. SAND2006-6569 and SAND2006-7911 document interim results from this effort; this report documents the final results. The problem is difficult because of the number of humans involved in a System of Systems environment and the generally poorly defined nature of the tasks that each human must perform. A two-pronged strategy was followed: one prong was to develop human models using a probability-based method similar to that first developed for relatively well-understood probability based performance modeling; another prong was to investigate more state-of-art human cognition models. The probability-based modeling resulted in a comprehensive addition of human-modeling capability to the existing SoSAT computer program. The cognitive modeling resulted in an increased understanding of what is necessary to incorporate cognitionbased models to a System of Systems analytic environment. et al., 2005)........................................................................ List of Tables Executive SummaryA Laboratory-Directed Research and Development project was initiated in 2005 to investigate Human Performance Modeling in a System of Systems analytic environment. SAND2006-6569 and SAND2006-7911 document interim results from this effort; this report documents the final results. The problem is difficult because of the number of humans involved in a System of Systems (SoS) environment and the generally poorly defined nature of the tasks that each human must perform. A two-pronged strategy was followed: one prong was to develop probabilitybased human models similar to those used in relatively well-understood probability based human performance modeling; another prong was to investigate more state-of-art human cognition models.Probability based performance modeling involves decomposing jobs into discrete tasks, often with decision points, such that the range of possibilities in performing the tasks is covered. Human Error Probabilities are then associated with the tasks, allowing a calculation of the estimated probability of failing (or succeeding) at the job. To apply this basic idea to a SoS environment, human activities are generalized so that anything a human does over some period of time is considered to be a task. Basic Error Rates, which can be found in the literature, are then assigned according to the general difficulty of the activity that the human is performing. With the assumption that it takes time to recover from an error when it is made, there is an analogous situation between human performance modeling and hardware reliability modelinghuman error rate is similar to component failure rate and human recovery time (time-to-reset) is similar to system downtime (time-to-repair). As with hardware systems, the environment can also affect human performance. Performance-Shaping Factors (PSFs), as defined in SAND2006-7911 and including stress an...
