🛠 Equipment Failure Dashboard with Predictive Maintenance and Customer Service Chatbot

This project is a Streamlit web application that provides interactive data analysis, predictive maintenance insights, and an integrated customer service chatbot for equipment failure management. It helps identify failure-prone models and components, perform root cause analysis using the Apriori algorithm, predict future equipment failures using Random Survival Forest models, and assist users with real-time answers through a conversational chatbot.

📌 Features

🔍 Data Analysis

• Upload equipment failure CSV files
• Filter data by model numbers and part names
• Visualize top models and parts by failure rate
• Root Cause Analysis using Apriori Algorithm for association rules

🔧 Predictive Maintenance

• Predict "Time to Failure" for equipment using Random Survival Forest
• Calculate Failure Risk Scores
• Analyze high-risk spare parts
• Visualize failure time distribution and risk score comparisons
• Suggest spare part optimization based on risk level

🤖 Customer Service Chatbot

• Conversational interface integrated into the dashboard
• Built using Gemini Flash 2.0, optimized for fast and accurate responses
• Trained on intent-based Q&A pairs generated from original equipment failure data
• Capable of answering queries related to:
  • Equipment models and their failure trends
  • Specific part failure reasons
  • Predictive maintenance insights and usage instructions
  • Navigation and feature help within the dashboard
