# Modified CMAPSS Dataset (Turbofan Engine Degradation)

## 📘 Description

This dataset is a **modified version** of the NASA C-MAPSS (Commercial Modular Aero-Propulsion System Simulation) turbofan engine degradation simulation dataset. The modification was created by our team as part of a submission for **RISTEK UI Datathon 2025**, in conjunction with the predictive modeling work we developed.

Each entry in this dataset corresponds to one engine's operating cycle. Engines begin with varying degrees of wear and manufacturing variation, operate normally, and eventually experience degrading performance leading to system failure. The task is to predict **Remaining Useful Life (RUL)** based on sensor and operating condition readings.

## 📂 Dataset Subsets

The dataset is divided into four subsets, consistent with the original C-MAPSS structure:

| Subset | Train Units | Test Units | Operating Conditions | Fault Modes                      |
|--------|-------------|------------|----------------------|----------------------------------|
| FD001  | 100         | 100        | 1 (Sea Level)        | 1 (High Pressure Compressor)     |
| FD002  | 260         | 259        | 6                    | 1 (High Pressure Compressor)     |
| FD003  | 100         | 100        | 1 (Sea Level)        | 2 (HPC + Fan Degradation)        |
| FD004  | 248         | 249        | 6                    | 2 (HPC + Fan Degradation)        |

## 🛠️ Modifications

The original dataset has been preprocessed and extended for easier machine learning use:

- **Added RUL column**: Remaining Useful Life (RUL) has been precomputed for each cycle in the training set.
- **Added headers**: All columns are clearly labeled for usability.
- **Converted format**: Original space-delimited files are now provided as `.csv` files.

## 🧾 Data Fields

Each row corresponds to a single time step (cycle) for one engine unit. It includes 27 columns:
unit_number, time_in_cycles, op_setting_1, op_setting_2, op_setting_3, sensor_1, sensor_2, ..., sensor_21, RUL


## 📈 Intended Use

- Benchmarking and training models for Remaining Useful Life (RUL) prediction
- Educational and research use in predictive maintenance and health monitoring

## ⚠️ Limitations and Considerations

- This dataset is simulated and may not fully reflect real-world engine behavior.
- Only includes two types of fault modes.
- Best used as a benchmark for research rather than direct deployment.

# Dataset CMAPSS yang Dimodifikasi (Degradasi Mesin Turbofan)

## 📘 Deskripsi

Dataset ini adalah **versi modifikasi** dari dataset simulasi degradasi mesin jet turbofan NASA C-MAPSS. Modifikasi ini dibuat oleh tim kami sebagai bagian dari **submisi untuk RISTEK UI Datathon 2025**, seiring dengan model prediktif yang kami kembangkan.

Setiap entri merepresentasikan siklus operasional dari satu mesin. Mesin dimulai dalam kondisi normal (dengan variasi keausan awal), kemudian mengalami degradasi hingga akhirnya gagal. Tugas utama dari dataset ini adalah memprediksi **Remaining Useful Life (RUL)** berdasarkan pembacaan sensor dan kondisi operasi.

## 📂 Subset Dataset

Dataset dibagi ke dalam empat subset seperti pada struktur CMAPSS asli:

| Subset | Unit Latih | Unit Uji | Kondisi Operasi     | Mode Kegagalan                  |
|--------|------------|----------|----------------------|---------------------------------|
| FD001  | 100        | 100      | 1 (Permukaan Laut)   | 1 (High Pressure Compressor)    |
| FD002  | 260        | 259      | 6                    | 1 (High Pressure Compressor)    |
| FD003  | 100        | 100      | 1 (Permukaan Laut)   | 2 (HPC + Degradasi Fan)         |
| FD004  | 248        | 249      | 6                    | 2 (HPC + Degradasi Fan)         |

## 🛠️ Modifikasi

Dataset asli dimodifikasi untuk memudahkan pemrosesan dan pemodelan:

- **Penambahan kolom RUL**: Sisa siklus hidup (RUL) dihitung dan ditambahkan.
- **Header kolom ditambahkan**: Semua kolom diberi nama deskriptif.
- **Format diubah**: File teks dipisahkan spasi diubah menjadi `.csv`.

## 🧾 Struktur Data

Setiap baris merepresentasikan satu siklus operasional untuk satu unit mesin dengan total 27 kolom:
unit_number, time_in_cycles, op_setting_1, op_setting_2, op_setting_3,
sensor_1, sensor_2, ..., sensor_21, RUL

## 📈 Penggunaan yang Disarankan

- Melatih dan menguji model prediksi Remaining Useful Life (RUL)
- Penelitian dan edukasi dalam konteks predictive maintenance

## ⚠️ Keterbatasan

- Ini adalah data hasil simulasi, bukan dari mesin nyata
- Hanya mencakup dua jenis mode kegagalan
- Sebaiknya digunakan sebagai benchmark eksperimen, bukan untuk deployment langsung
