Opis:: Integrated general models of approximate approaches of complex multi-state series and parallel systems, linking their reliability and availability improvement models and their operation processes models caused changing reliability and safety structures and components reliability characteristics in different operations states, are constructed. These joint models are applied to determining improved reliability and availability characteristics of the considered multi-state series and parallel systems related to their varying in time operation processes. The conditional reliability characteristics of the multi-state systems with hot, cold single reservation of component and the conditional reliability characteristics of the multi-state systems with reduced rate of departure by a factor of system components are defined.

Opis:: There is presented the application of the integrated software tools to the reliability of the improved exemplary complex technical system prediction. There are considered three ways of the exemplary system reliability improvement, i.e. a hot single reservation of its components, a cold single reservation of its components and replacing its components by the improved components with reduced intensities of departure from the reliability state subsets. Automatically obtained, using the computer program CP 8.16, the evaluations of these ways improved exemplary system unconditional multistate reliability function, the expected values and the standard deviations of its unconditional lifetimes in the reliability state subsets and the mean values of its lifetimes in the particular reliability states are presented. Moreover, in the case when the improved system is repairable, its renewal and availability characteristics are estimated using the computer program CP 8.8 with appropriately given data.

Opis:: Many universities in Poland are based in historic buildings. As public facilities, they must have accessibility for people with disabilities. Therefore, historic buildings undergo regular reconstruction to ensure accessibility on the basis of technical and construction regulations and the Convention on the Rights of Persons with Disabilities. For the purpose of the study, those with exceptional architectural, cultural and historical are presented. The article is concerned with determining the current state of accessibility of selected Polish universities for students with mobility disabilities. The first part of the paper deals with the verification of the background material in the form of statistical data and support programmes for the studied group of users. The second part presents historical information about the historic buildings along with a qualitative analysis of the elements already applied to eliminate architectural barriers. Nine selected historical teaching facilities located both in Warsaw and scattered throughout the country were analysed using the field observation method. The conclusion presents the results indicating the application in the realizations of the principle of rational improvement stating that the preservation of historic value can become paramount to ensuring full accessibility. Still, monuments should be treated individually, and the same applies to disabilities, where each is different and requires individual perception and treatment.

Opis:: Paper presents the methodology of shaping dependability of devices used in process with use key performance indicators for increasing Overall Equipment Efficiency (OEE) which are a subject of devices' parameters monitoring under operation. Value of Overall Equipment Efficiency describes the technical state of devices included into production process. Value itself can be different for different production lines even in one industry. For engineers it is important to put all possible effort to increasing values of particular key performance indicators which are building Overall Equipment Efficiency. Values of particular key performance indicators, shows to experienced engineer real technical state of whole production line. Presented in paper selected indicators are connected and have influence for each other, moreover operation parameters of devices' are characterizing production process. Key performance indicators presented in paper represents three the most important aspects of the production process: handling of the process, operators' area of responsibility, management of the process, managers' area of responsibility and optimization of the process, planners' area of responsibility. Only proper cooperation of these three groups of people can benefits requested result. From owners point of view, presented areas have the same importance, problems created in one of them can negatively influence for overall income of whole enterprise.
