Method of assessment of technical object aptitude in environment of exploitation and service conditions. eksploatacja i niezawodnosc -Maintenance and reliability 2015; 17 (1): 54-63. rafał Grądzki Paweł LindsTedTMethod of assessMent of technical object aptitude in environMent of exploitation and service conditions Metoda oceny stanu zdatności obiektu technicznego w otoczeniu warunków użytkowania i jakości obsługi* In the article, results of exploitation research of three various technical objects (public transportation bus engines) are presented. Gathered data is presented in three sets (1 -concerning object, 2 -concerning driving conditions, 3 -concerning driver, where sets 2 and 3 are object environment) in form of points (expert number assessments). Relation between point information on object and point information on environment was described using coupled state interaction equations. Such approach allowed to determine the following for each moment of exploitation: technical condition parameter a T and operating condition parameter a R , therefore in each moment of exploitation data regarding operating and technical condition of exploited object (bus) is available.This data allows for identification of object aptitude condition and thus optimally control processes of exploitation and service of particular objects as element of set of objects and set of objects. Keywords: diagnostics, regulation, aptitude. W artykule przedstawiono wyniki badań eksploatacyjnych trzech różnych obiektów technicznych (silników autobusów komunikacji miejskiej). Zebrana informacja została przedstawiona w 3 zbiorach (1 -dotyczy obiektu, 2 -dotyczy warunków jazdy, 3 -dotyczy kierowcy; przy czym zbiory 2 i 3 stanowią otoczenie obiektu) w postaci umownych punktów (eksperckich liczbowych ocen). Relację między punktową informacją o obiekcie i punktową informacją o otoczeniu opisano za pomocą sprzężonych równań stanu. Takie podejście pozwoliło wyznaczyć dla każdej chwili eksploatacji: parametr stanu technicznego aT i parametr stanu działania aR, Zatem w każdej chwili eksploatacji może być dostępna informacja o stanie technicznym i stanie działania każdego eksploatowanego obiektu (autobusu). Informacja ta pozwala identyfikować w każdej chwili stan zdatności obiektu, a zatem pozwala optymanie sterować procesami użytkowania i obsługi poszczególnych obiektów jako elementu zbioru obiektów i zbiorem obiektów.Słowa kluczowe: diagnostyka, regulacja, zdatność. IntroductionLong term exploitation of machine leads to its gradual damage caused by decrease in its material properties and mechanical wear. Technical service is therefore tasked with constant (current) assessment of object technical condition and ability of proper operation of technical objects based on measured diagnostic signals, exploitation signals and conditions in which the object is exploited. This allows to observe chan...

Correlation between Defects and Technical Wear of Materials Used in Traditional Construction

“…A research attempt to assess the technical condition of downtown tenement houses in Wroclaw was described in detail in reports [ 7 ] and publications [ 8 , 9 ]. The approach to the investigation of building structures meets the broad requirements of their maintenance and use and is derived from standard BS 8210:2012 “Guide to facilities maintenance management” [ 10 ], with detailed research methods and tools being provided in publications [ 11 , 12 , 13 , 14 , 15 , 16 ]. The life cycle of a building structure is presented within the engineering approach in articles [ 17 , 18 , 19 , 20 , 21 ], and with regards to cost approach in papers [ 22 , 23 , 24 , 25 , 26 , 27 ].…”

Overdurability and Technical Wear of Materials Used in the Construction of Old Buildings

“…This is needed in order to determine that there is no excessive rapid degradation and that no preventive measures to slow down the degradation rate need to be taken. This finding results from the fact that in the basic period of use, the degradation processes may not be advanced and the symptoms of deterioration may go unnoticed [ 28 ]. Usually, in order to assess the advancement of degradation processes, investigations, the scope of which will be different than for severely damaged structures, are needed.…”

Comparison of operational availability of public city buses by analysis of variance

“…The study [24] presents a method of designing the availability of technological objects, and in [10] a theory pertaining to semi-Markov processes was used based on the authentic municipal transport system. In [2] the authors identified the object's aptitude condition, and thus optimal control processes of operation and service of particular objects on the example of public transportation bus engines.…”
