Predictive Maintenance for Healthcare Equipment

Project Overview

This project aims to predict equipment failures in healthcare facilities by analyzing various operational metrics like usage hours, temperature, vibration levels, and maintenance history. Using machine learning models, this project provides a way to implement predictive maintenance strategies, reducing downtime and maintenance costs.

Dataset

The dataset used for this project is healthcare_equipment_data.csv (or the Excel version healthcare_equipment_data.xlsx). It contains the following features:

• equipment_id: Unique ID for each equipment.
• usage_hours: Number of hours the equipment has been used.
• temperature: Operating temperature of the equipment (in degrees).
• vibration_level: Vibration intensity level of the equipment.
• pressure_level: Operating pressure level.
• last_maintenance: Hours since the last maintenance.
• failure: Binary target variable indicating if a failure occurred (1 = Yes, 0 = No).

Project Files

• notebook.ipynb: Jupyter notebook containing the complete code for data preprocessing, visualization, model building, and evaluation.
• healthcare_equipment_data.csv: The CSV file containing the dataset (mock data provided).
• healthcare_equipment_data.xlsx: The Excel version of the dataset (optional).
• README.md: This file, providing an overview of the project.

Steps in the Jupyter Notebook

1. Import Libraries

• The notebook begins by importing necessary libraries like pandas, numpy, matplotlib, seaborn, and machine learning tools from sklearn.

2. Data Loading and Exploration

• The dataset is loaded using pd.read_csv() or pd.read_excel().
• Initial data exploration includes checking the structure of the dataset (.info(), .describe()), handling missing values, and visualizing feature distributions.

3. Data Visualization

• Histograms and correlation heatmaps are generated using matplotlib and seaborn to explore feature relationships.

4. Data Preprocessing

• Handling missing values, encoding categorical features (if applicable), and splitting the dataset into training and testing sets.
• Features are standardized using StandardScaler() to normalize data for machine learning models.

5. Model Building

• A Random Forest Classifier is used for the predictive task.
• The model is trained on the training set, and predictions are made on the test set.

6. Model Evaluation

• The model is evaluated using a confusion matrix, accuracy score, and a classification report. These metrics help assess the model's performance in predicting equipment failures.

7. Feature Importance

• Feature importance is plotted to understand the impact of each feature on the prediction of failures.

8. Conclusion

• A summary of the model's performance is provided, along with insights into which factors are most critical in predicting equipment failures.
