The article deals with the issues of a conceptual approach to determining the life cycle of a passenger car. The fleet of passenger car mainly consists of models developed and manufactured in the 70-90s of the last century at car plants in Germany and Russia. They are obsolete both morally and physically. This necessitates the renewal of the passenger car fleet by purchasing cars of both domestic and foreign production. In modern conditions, the user of new technology is interested not only in the purchase price, but also in the after-sales costs. This is reflected in the life cycle cost. It is proposed to use a cascade life cycle model for a passenger car. The stages of the life cycle of a passenger car during operation on the railways of Ukraine have been determined. The components of each stage of the life cycle of a passenger car are considered. For a transport company that intends to operate a passenger car, the costs of the first three stages are directly expressed in the initial cost of the car - the purchase price. The life cycle cost (LCC) of a passenger car will be determined by summing up the individual outflow of funds (expenses) at each specific stage (calculation step) of the service life of the equipment. The life cycle assessment of the technical system of railway transport can work at any stage of the life cycle.

Objective: To determine the main approaches to safety management of high-speed railway transport on the basis of modern international and domestic practices in the specified sphere. Methods: Analysis methods of security risks on railway transport were considered in accordance with modern international standards of management of interconnected indices’ complex, which include reliability, availability, maintainability and safety and cost (Life Cycle Cost – LCC) at all stages of transportation systems’ life cycle: EN 50126 (IEC 62278), EN 50128 (IEC 62279), EN 50129 (IEC 62425) and IEC 60300-3-3. Results: The main approaches to safety measures of high-speed railway lines (VSM) were detected. The former involve using a lifecycle concept of engineering systems and facilities, management methodology of RAMS/LCC interconnected indices’ complex at all stages of a life cycle, wide application of the process approach and the tools of quality and safety management systems, development and implementation of technological maturity assessment methodology for security management activities, as well as object-oriented and coherent improvement of regulatory base, the systems of administrative and control and permission authorities, technical and technological development, management of external, inland and allocated risks under market relations. Practical importance: The examined approaches of VSM safety control make it possible to obtain a priori estimates of safety control processes and thus determine the achieved level of safety together with the levels of technological maturity of railway organizations’ processes.

Abstract In today’s competitive marketplace, the quality of a product is becoming increasingly more important. The informed customer not only weighs the ability of the product to meet his/her requirements, and the purchase price of the product, but also the money that must be expended to maintain the function of the product. Hence, lowering the life-cycle cost of a product will increase its value and attractiveness to the customer.

The Shanghai Transport Committee has estimated that passenger traffic increased fivefold between 2005 and 2014, and will continue to increase. At the same time, the maintenance costs of the Shanghai Metro have increased to about six times their original value. To ensure reliability, availability, maintainability and safety (RAMS) in railways, equipment sometimes needs to be upgraded; new technology is an effective way of modernizing the system. Condition monitoring techniques are considered to be a pragmatic approach to improve RAMS in railways. Bearings are seen to be a key factor in the successful operation of railways, as their performance is related to safety and reliability. To meet the safety requirements, an efficient method is to implement a real-time condition monitoring (RTCM) technique. To evaluate the economic cost of this investment in RTCM, the life cycle cost (LCC) should be considered. A Petri net combined with the Monte Carlo method is used to simulate the LCC evaluation process and a case study of how to employ this method is presented.

Abstract Duracorr is low-cost, utilitarian 11% Cr stainless steel with more corrosion resistance and life-cycle cost advantages than weathering steels. The steel may be used where a combination of abrasion and corrosion resistance is required. This datasheet provides information on composition, physical properties, microstructure, hardness, tensile properties, and bend strength as well as fracture toughness. It also includes information on corrosion resistance as well as joining. Filing Code: SS-680. Producer or source: Lukens Steel Company.
