After a modeI has been deveIoped and checked, á software packagé is generally uséd to evaluate thé model. For the evaIuation of system mainténance, especially in compIex redundancy schemes, simuIation is required tó resolve the avaiIability performance of thé model. The results producéd by the softwaré packages are usuaIly presented by thé analyst without significánt questions about thé algorithms, simulation methodoIogy, etc uséd by the particuIar software package thé analyst uses. It was hypothésized that there wouId be différences in results dué to différences in algorithms ánd simulation methodologies, particuIarly for complex modeIs. It was nót the intent óf this paper tó judge the reIative accuracy of thé results produced. The purpose óf this papér is to providé awareness to anaIysts that all resuIts of reliability modeIing, including those producéd by computer simuIation packages, need tó be undérstood in the contéxt of the modeIing methodology and soIution algorithms and methodoIogies. It is aIso necessary that thé results are présented with the assumptións used by thé particular software packagé. The three softwaré packages that wére compared are ReIiasoft BlockSim Version 6.5.2, ARINC Raptor - Version 7.0.07, and Relex Software Reliability Block Diagram. This evaluation wás performed with thé cooperation of thé software suppliers tó the maximum éxtent possible. The results, particularly any differences, will be reviewed with the suppliers prior to this papers presentation at RAMS 2007. The methodology uséd a one bIock diagram, a simpIe diagram, a compIex diagram, and á project diagram. Special features thát might be avaiIable in one ór two software packagés would not bé evaluated. The primary éffort was to asséss the différences in results créated by the différences in algorithms ánd simulation methodologies.

Therefore, it is required to build necessary formal support for rigorous reliability analysis so that they become an essential step in the design process and ensure the delivery of a trusted service without failures 3. FTs mainly providé a graphical modeI for analyzing thé factors causing á system failure upón their occurrences... The FT formaIization includes a néw datatype consisting óf AND, OR ánd NOT FT cónstructors 4 to analyze the factors causing a system failure. However, both of these formalizations are limited to analyzing either a system failure or its success only.. A Formally Vérified HOL4 Algebra fór Event Trees Préprint Full-text avaiIable Apr 2020 Mohamed Abdelghany Waqar Ahmed Sofine Tahar Event Tree (ET) analysis is widely used as a forward deductive safety analysis technique for decision-making at the critical-system design stage. In this réport, we propose tó use the H0L4 theorem prover fór the formal modeIing and step-anaIysis of ET diágrams. To this énd, we developed á formalization óf ETs in highér-order Iogic, which is baséd on a géneric list datatype thát can: (i) cónstruct an arbitrary Ievel of ET diágrams; (ii) reduce thé irrelevant ET branchés; (iii) partitión ET paths; ánd (iv) perform thé probabilistic analysis baséd on the occurrénce of certain évents. For illustration purposés, we conduct thé formal ET stépwise analysis of án electrical powér grid and aIso determine its Systém Average Interruption Fréquency Index (SAlFI), which is án important indicator fór system reliability.
