Tramway transit has an important place within the public transportation system of Belgrade. However, due to the very unfavorable age structure, the bad condition of tramway tracks and infrastructure, as well as the maintenance system that require significant advancement, Belgrade tramways are in very bad repair, so the transport requirements are no...

The design of maintenance system and the corresponding logistic support is a very complex process, during which the aim is to find the compromise solutions regarding the relations among different maintenance procedures and the ways of their implementation. As a result of this, various solutions can be adopted, since this is conditioned by a series...

According to the Belgrade Master Plan for 2021, the public transportation system for the city and its region will include three rail modes: a modernized existing tramway, regional rail, and a new light rail transit (LRT) mode. In the coming years all three rail modes should be developed simultaneously and in a coordinated manner. The introduction o...

In recent years, motor vehicles industry has shown a tendency of replacing electromechanical components by mechatronic systems with intelligent and autonomous properties. The integration of hardware components and implementation of advance control function characterize this replacement. In this paper, we have applied the system approach and system...

The paper presents the results of the condition and characteristics of tires that are in use in Serbia. Data on wear patterns, sizes, ages, brand, type, more than 700 tire and vehicle information to which they are mounted. Data about tread depth, dimensions, tire age, brand and type of more then 700 tested tires were gathered, as well as informatio...

The brake friction materials in an automotive brake system are considered as one of the key components for overall braking performance of a vehicle. The sensitivity of friction material performance and accordingly brake performance, versus different operating regimes, has always been an important aspect of its functioning. In this paper, the influe...

This paper shows the way FMEA method (Failure Modes and Effects Analysis), which is widely used in motor vehicles industry, can be improved and later used during certain stages of vehicle life cycle. This is illustrated by the example of bus superstructure development. A number of possibilities have been given for the advanced method application du...

Asset Management is the culmination of a long history of development in the management of physical assets. It is about asset intensive businesses achieving a level of service, risk profile and funding requirement that is acceptable to stakeholders for the life of the assets. Asset Management involves making decisions about the interventions to phys...

We live in the world comprised of systems and risks. With systems and technology there also comes the exposure to mishaps because systems can fail or work improperly which results in damage, injury and deaths. The possibility that a system fails and results in death, injury, damage and the like is referred to as mishap risk. The key to system safet...

Considering the possible failures within a technical system represents a major engineering task. This paper suggests a completely new approach to the widely accepted failure analysis method FMEA. The paper describes a method named Failure Modes, Effects and Risks Analysis or FMERA, which is a technique of design engineering, used at risk identifyin...

In this paper authors have presented the forecasting and decision support systems in modern business systems management. The last, fourth, phase of EPPA analyzes, witch is a problem quantification phase that process data collected in previous phases of shown EPPA method. All four components that are going to be quantified by the expert team, are de...

New production and information technologies, as well as intelligent production system, are based upon knowledge. That demands intensive and constant education of people. Very small number of engineers can detain its competence without constant and continually education. The most of them needs permanent knowledge development through carrier if they...

The tram traffic has important place and good perspektive in Belgrade public transportation sistem. According to the curent state and to the future needs, city of Belgrade planns revitalization, rehabilitation and modernisation of this form of transportation. The mission of "Cost-benefit analysis of Belgrade tram roling stok" was to recommend renew...

Deals with sources of fuzziness in individual parts and stages of maintenance and utilization of vehicles in large fleets. Effective vehicle fleet maintenance management requires data on reliability and maintainability. In most cases, however, available data are insuffucient for proper statistical identification of performance, making it impossible...
