{"product_id":"9783832528928","title":"Generic Construction of Availability Calculation Models for Safety Loops in Process Industry","description":"\u003cp\u003eA generic approach is proposed in this work that automatically constructs suitable calculation models from a herefore invented formal description language. Two positive effects arise from that: firstly, all inherently and explicitly contained complexity of Safety Instrumented Systems is identified once and condensed into a set of transformation formulas generating the actual calculation models. Secondly, providing a flexible and extensive description language encourages smart and quick engineering processes, enables for non-standard solutions, and relieves safety engineers from the challenge of actually deriving explicit calculation models by hand. A suitable new type of discrete time multiphase markov model is chosen as mathematical basis, and comes along with the required solver algorithms for retrieving the desired unavailability characteristics: the probability of failure on demand (PFD), and the probability of fail-safe (PFS), i.e. an operational unavailability as economical indicator.\u003c\/p\u003e","brand":"Logos Verlag","offers":[{"title":"Default Title","offer_id":47041660485872,"sku":"9783832528928","price":55.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783832528928_p0.jpg?v=1763687501","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783832528928","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
