Under these conditions, frequency estimates use considerable expert belief in determining how the controls affect the accident frequency. To evaluate and document beliefs about control effectiveness, they have modified a traditional Bayesian approach by using approximate reasoning (AR) to develop prior distributions. Their method produces accident frequency estimates that separately express the probabilistic results produced in Bayesian analysis and possibilistic results that reflect uncertainty about the prior estimates. Based on their experience using traditional methods, they feel that the AR approach better documents beliefs about the effectiveness of controls than if the beliefs are buried in Bayesian prior distributions. They have performed numerous expert elicitations in which probabilistic information was sought from subject matter experts not trained in probability. They find it much easier to elicit the linguistic variables and fuzzy set membership values used in AR than to obtain the probability distributions used in prior distributions directly from these experts because it better captures their beliefs and better expresses their uncertainties.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

First, manufacturing goals-quality parts at the required production rate-can be met despite the \"fact\" that the system did not meet its uptime requirements. Second, process failures can contribute more to manufacturing downtime than actual hardware failures. Proper modeling of manufacturing systems to include all sources of downtime, whether hardware, software, human, or process as well as the production rates, will provide a more accurate depiction of operation. Methods have been developed by others to model software and human reliability. The approach paper details a model for including process reliability and production capacity. The resultant analysis provides a method to help assure that reliability improvement efforts are focused on the primary root causes of downtime-in many cases process problems and not more costly and sometimes technologically infeasible hardware improvement. The analysis also points to addressing the production capabilities so that the operational goal for the manufacturing equipment is not missed.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.

Operational efforts in this area are often primarily focused on production and not on safety. A most important reason, as this paper shows, is that the effectiveness of safety investments can neither be calculated nor measured nor traced back adequately, while the effects of production investments immediately show up in terms of profitability. Market share and competition reinforce that attention is primarily focused on production. This paper shows that risk reduction as well as performance improvement can be achieved by better control of the operational processes. In this paper, a method is presented to model, analyse and qualify the control of an operational process. Basic concepts are formally defined, from which a reference model, the so-called 'basic controlled process' is derived. Real life processes can be compared to this reference model. Differences between model and reality are categorized and the control-ability of the real life process can be qualified. Subsequently, the formalism is applied to a real life situation, by means of a case study. It is clearly shown that the presented formalism offers the possibility to analyse the 'control-ability' of an operational process and to identify its most serious deficiencies. From this case, it can be concluded that local control of sub-processes is no guarantee that the operational process on company level is also controlled.","PeriodicalId":395613,"journal":{"name":"Annual Reliability and Maintainability Symposium. 2002 Proceedings (Cat.
