# Examples of Reliability Models of a Renewable Technical Object in Relation to Special Vehicles

## TL;DR

This paper presents reliability models for garbage trucks, comparing part replacement and repair strategies using real-world data.

## Contribution

The novelty lies in applying specific reliability models to special vehicles using operational data from city cleaning services.

## Key findings

- Reliability models for garbage trucks were developed using operational data from service books.
- Two models were compared: one with part replacement and one with part repair.
- The models showed benefits in predicting and improving vehicle reliability.

## Abstract

The article describes examples of reliability models of a renewable technical object. The proposed models are mathematical models that, according to the author, are best suited to presenting problems resulting from the operation of the analyzed technical objects. These objects are special vehicles, in this case garbage trucks with plate compaction and rear loading of waste containers. The author described two models: one where a model was analyzed and the replacement of a worn part with a brand new part was assumed, and a model where the worn element was repaired (renewed), so that after the repair, the element showed features as if it were a brand new element. Each of the examples was considered based on operational data from city cleaning companies. Data obtained from service books was used for calculations. The analyzed examples are concluded with short conclusions. In turn, the entire article ends with a summary in the form of conclusions resulting from the use of these specific models. The author draws attention to the reasonableness of their use in the scope analyzed by him, and the benefits that result from the use of these models.
