Abstract
ABSTRACTIn order to master the main malfunction and the law of occurrence of the vehicle which affects the operational reliability of the Straddle-Type Monorail traffic, this paper, based on the structural characteristics of monorail vehicle system and the statistical data of vehicle operational malfunction, uses the analysis method of system reliability engineering to study and determine the key factors that affect the operational reliability of monorail vehicle. Then, the operational reliability evaluation index system of monorail vehicle is established based on the influencing factors. Finally, the AHP (Analytic Hierarchy Process) method is used to determine the weights of each index, and the fuzzy comprehensive evaluation method is used to evaluate the operational reliability of monorail vehicle synthetically. The evaluation results have some guidance on the development of more effective maintenance strategies for monorail vehicle maintenance departments.
Highlights
The Straddle-Type Monorail Vehicle is used as a carrier for the straddle-type monorail system (Timan, 2015)
Based on an urban rail transit line operational safety, the line operational safety evaluation index system of urban transit was established (Wang yanhui, 2013), in which the line operation safety index of urban rail transit was evaluated with the method of combination weights
The contributions of this study are as follows:(1)Straddle-Type Monorail Vehicle operational malfunction statistical is analyzed based on a large quantity of failure data; (2)Straddle-type monorail vehicle operation reliability evaluation index system is established based on statistical analysis; (3)The fuzzy comprehensive evaluation of the operation reliability of Straddle-Type monorail vehicle is established
Summary
The Straddle-Type Monorail Vehicle is used as a carrier for the straddle-type monorail system (Timan, 2015). Life cycle costing was a well-established method for the evaluation of alternative asset options and to produce a spend profile for an asset over its anticipated life-span, different aspects related to the failure costs within the LCCA was explored for the rail freight industry (Chile) (Parra, Crespo, Kristjanpoller, & Viveros, 2012). Both frequentist statistics and Bayesian inference techniques were employed by the parametric statistical models to combine information and contrasted to illustrate different statistical methods for combining information across multiple testing events for the Stryker family of vehicles (Steiner, Dickinson, Freeman, Simpson, & Wilson, 2015). The contributions of this study are as follows:(1)Straddle-Type Monorail Vehicle operational malfunction statistical is analyzed based on a large quantity of failure data; (2)Straddle-type monorail vehicle operation reliability evaluation index system is established based on statistical analysis; (3)The fuzzy comprehensive evaluation of the operation reliability of Straddle-Type monorail vehicle is established
