Introduction

This research paper proposes an enhanced Digital Vehicle Inspection Report (DVIR) system that leverages artificial intelligence (AI) to revolutionize defect tracking and management in fleet operations. The system aims to support associating and tracling defects on a per-asset basis and individually handling these defects with advanced AI capabilities.

Goals

The proposed solution to enhance the Digital Vehicle Inspection Report (DVIR) product revolves around integrating advanced artificial intelligence (AI) capabilities. This expansion focuses on a detailed breakdown of how AI can be incorporated into various aspects of the DVIR system to improve efficiency, accuracy, and compliance.

Active Assets Management
AI-Driven Asset Status Classification

• Implement AI algorithms to classify the status of assets (In Service, Out of Service) based on their current condition, historical data, and detected defects.
• Utilize predictive analytics to forecast potential issues, enabling proactive maintenance and reducing unexpected down- times.

Real-Time Asset Monitoring

• Integrate sensors and IoT devices to gather real-time data from assets.
• AI models analyze this data stream to detect anomalies and update asset status dynamically.

Inspection Reports Enhancement
Automated Defect Identification

• Use AI to automatically identify and log defects during inspections.
• Machine learning models analyze images, sensor data, and driver inputs to detect and categorize defects accurately

Historical Data Integration

• AI algorithms assess historical inspection data to identify recurring issues or patterns in defects.
• Provide drivers and managers with insights into asset health trends over time.

Defects Management Smart Defect Tagging

• AI categorizes defects based on severity and type, specific to each asset class (e.g., Trailer Defect List vs Tractor Defect List).
• Defect tagging assists in prioritizing maintenance tasks and resource allocation.

Defect Status Lifecycle Management

• Implement AI to manage the lifecycle of each defect, from identification to resolution.
• Predictive models suggest the most efficient resolution paths and estimate repair times.

User Flow Optimization
AI-Assisted Report Generation

• Integrate AI to simplify the report creation process, recommending assets for inspection based on their status and usage patterns.
• Natural language processing (NLP) can be used to interpret driver notes and automatically populate relevant fields in the report.

Defect Resolution Guidance

• AI provides step-by-step guidance for drivers to resolve or verify defects, based on similar past instances and manufacturer guidelines.
• Interactive AI tools can be developed to assist drivers in realtime during the inspection process.

Enhanced AI Features for Drivers and Managers
AI-Enhanced Driver Interface

• AI-powered search and filter options for drivers to easily access past reports and active assets.
• Recommendation engine to highlight assets needing immediate attention based on their defect status.

Managerial AI Dashboards

• Develop AI-driven dashboards for managers, showcasing realtime fleet status, defect resolution progress, and compliance reports.
• Implement anomaly detection systems to alert managers about critical issues in the fleet.

Regulatory Compliance and AI

• Ensure AI models are trained in line with industry regulations and safety standards.
• Automatic documentation and reporting features to maintain regulatory compliance, especially for critical defects that could render an asset non-compliant.

By infusing AI into the DVIR system, the solution not only enhances the efficiency of asset management and defect handling but also brings a new level of intelligence and foresight into fleet operations. It represents a significant step towards a more datadriven, predictive approach to vehicle inspection and maintenance in the logistics and transportation industry.

User Flow Enhancement With AI

Incorporating AI into the DVIR system revolutionizes the user experience by streamlining workflows, enhancing decisionmaking, and automating defect management. Below is an expanded overview of the enhanced user flow, supported by AI, with corresponding database design, pseudocode, and flowcharts.

AI-Assisted Report Initialization

• Flow: When creating a new report, the AI suggests relevant assets based on historical data and current conditions.
• Database: ‘reports‘ table to store report metadata; ‘assets‘ table linked to ‘reports‘ for asset-report association.
• Pseudocode: “‘python def initialize_report(user_id, current_time): assets = AI_model.recommend_assets(user_id, cur- rent_time) report_id = create_new_report(user_id, assets, cur- rent_time) return report_id “‘

Dynamic Defect Identification and Categorization

• Flow: As defects are logged, AI categorizes and prioritizes them based on severity and asset type.
• Database: ‘defects‘ table with fields for ‘category‘, ‘severity‘, ‘status‘, and foreign key to ‘assets‘.
• Pseudocode: “‘python def log_defect(report_id, asset_id, defect_data): category, severity = AI_model.analyze_defect(defect_data) defect_id = add_defect_to_database(report_id, asset_id, category, severity) update_asset_status(asset_id, severity) return defect_id “‘

Real-Time Asset Status Update

• Flow: Asset status is updated in real-time based on defect severity and AI predictions.
• Database: ‘asset_status‘ field in the ‘assets‘ table.
• Pseudocode: “‘python def update_asset_status(asset_id, severity): status = determine_status_based_on_severity(severity) update_ asset_in_database(asset_id, status) “‘

Flowcharts

• Report Initialization Flowchart - Start -> User initiates report creation -> AI suggests assets -> User confirms assets
• End
• Defect Logging Flowchart - Start -> User logs defect -> AI categorizes defect -> Defect added to report -> AI updates asset status -> End.

Database Schema
Tables

• ‘reports‘: Fields include ‘report_id‘, ‘user_id‘, ‘timestamp‘, etc.
• ‘assets‘: Fields include ‘asset_id‘, ‘asset_type‘, ‘status‘, etc.
• ‘defects‘: Fields include ‘defect_id‘, ‘report_id‘, ‘as- set_id‘, ‘category‘, ‘severity‘, ‘status‘, etc.

Relationships

• ‘reports‘ to ‘assets‘: One-to-many, as each report can include multiple assets.
• ‘assets‘ to ‘defects‘: One-to-many, as each asset can have multiple defects.

Key User Stories Supported by AI

Enhancing the DVIR system with AI support greatly improves the user experience for both drivers and managers. Below, we explore key user stories that are enhanced by AI, along with detailed code examples illustrating how these functionalities can be implemented.

User Stories
Driver Access to DVIR Based on Permissions

• Story: Drivers can access the DVIR system only if they have the appropriate permissions.
• Implementation: Use an authentication and authorization system to control access.
• Code: “‘python def access_dvir(user_id): if has_permission(user_id, "DVIR_ACCESS"): dvir_reports = get_dvir_reports(user_id) return dvir_reports else: raise AccessDeniedException("User lacks DVIR access permission.") “‘

Selecting Vehicles and Viewing Past Reports

• Story: Drivers select vehicles and view past reports for those vehicles.
• Implementation: Fetch vehicle data and related reports from the database.
• Code: “‘sql SELECT * FROM reports WHERE vehicle_id = ? AND report_ date >= ? “‘ “‘python def get_past_reports(vehicle_id, days=8): past_date = get_date_ days_ago(days) reports = execute_sql_query("SELECT * FROM reports WHERE vehicle_id = ? AND report_date >= ?", [vehicle_id, past_date]) return reports “‘

Adding and Resolving Defects for Assets

• Story: Drivers can add new defects to assets and resolve active defects.
