AI Driven Predictive Maintenance Workflow for Vehicle Fleets

Predictive Maintenance Algorithm Development for Vehicle Fleets

1. Define Objectives

1.1 Identify Key Performance Indicators (KPIs)

Establish KPIs to measure the effectiveness of the predictive maintenance strategy, such as vehicle downtime, maintenance costs, and repair frequency.

1.2 Determine Scope of Implementation

Decide on the specific vehicle models and fleet size to be included in the predictive maintenance program.

2. Data Collection

2.1 Sensor Data Acquisition

Utilize IoT sensors installed in vehicles to collect real-time data on engine performance, fuel consumption, and other critical metrics.

2.2 Historical Data Compilation

Gather historical maintenance records and failure logs to create a comprehensive dataset for analysis.

3. Data Preprocessing

3.1 Data Cleaning

Remove inconsistencies and outliers from the collected data to ensure accuracy in the analysis.

3.2 Data Normalization

Standardize data formats and scales to facilitate effective machine learning model training.

4. Model Selection
