# DigitalTwin - Optimum Overhaul App (be-optimumoh) API Documentation
|
|
||||||
|
|
||||||
This document maps all the API endpoints, route handlers, database models, and external service layers inside the `be-optimumoh` microservice. It is a FastAPI-based backend engine managing Overhaul schedules, standard scopes, spare parts readiness, Temporal workflow executions, and optimization/constraint calculations.

## 🛡️ App Middlewares & Framework Architecture
|
|
||||||
|
|
||||||
### 1. Security Headers Middleware
|
|
||||||
FastAPI adds rigid HTTP security headers to all incoming connections inside `src/main.py`. In production, it enforces `Strict-Transport-Security`, `X-Frame-Options` (DENY), and full CSP blockades. In development mode, it supports relaxed parameters.
|
|
||||||
|
|
||||||
### 2. Request Sanitization & Slowapi Limiting
|
|
||||||
All JSON and path structures pass through `RequestValidationMiddleware` (`slowapi` integration) to enforce rate limiting thresholds globally, returning standard payload error formatting on breaches.
|
|
||||||
|
|
||||||
### 3. Multi-Session Context Scoping
|
|
||||||
Scoped database sessions are generated per request context dynamically utilizing ContextVars in `src/context.py` and SQLAlchemy's async connection pool engine:
|
|
||||||
* `db` session: Optimum overhaul local PostgreSQL dataset (`default`).
|
|
||||||
* `collector_db` session: Asset metadata and equipment configurations.

# Unit Testing Guide - be-optimumoh
|
|
||||||
|
|
||||||
This document provides instructions on how to set up and run unit tests for the **be-optimumoh** project.
|
|
||||||
|
|
||||||
## 1. Preparation
|
|
||||||
|
|
||||||
### Install Dependencies
|
|
||||||
Ensure you have all dependencies installed. This project uses `poetry`.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Install dependencies
|
|
||||||
poetry install
|
|
||||||
```
|
|
||||||
|
|
||||||
## 2. Configuration
|
|
||||||
|
|
||||||
### Pytest Configuration
|
|
||||||
Ensure the `pytest.ini` file in the root directory points to the `unit` test folder:
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[pytest]
|
|
||||||
testpaths = tests/unit
|
|
||||||
python_files = test_*.py
|
|
||||||
asyncio_mode = auto
|
|
||||||
```
|
|
||||||
|
|
||||||
## 3. Running Tests
|
|
||||||
|
|
||||||
### Run Unit Tests
|
|
||||||
To run all unit tests in the project:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
poetry run pytest tests/unit
|
|
||||||
```
|
|
||||||
|
|
||||||
### Run Specific Unit Test File
|
|
||||||
```bash
|
|
||||||
poetry run pytest tests/unit/test_specific_feature.py
|
|
||||||
```
|
|
||||||
|
|
||||||
## 4. Best Practices
|
|
||||||
|
|
||||||
- **Isolation**: Unit tests should be isolated from external services. Use mocking for APIs and databases.
|
|
||||||
- **Async Testing**: Use `@pytest.mark.asyncio` for asynchronous test functions.

The optimization model is based on the **Expected Total Cost per Unit Time (CPUT)** theory, a standard approach in reliability engineering for age-replacement and block-replacement policies.
|
|
||||||
|
|
||||||
### Objective Function
|
|
||||||
The goal is to find an overhaul interval ($T$) that minimizes the total expected cost amortized over time:
|
|
||||||
|
|
||||||
$$C(T) = \frac{C_{Preventive} + C_{Corrective} \cdot E[N(T)]}{T}$$
|
|
||||||
|
|
||||||
Where:
|
|
||||||
* **$T$**: The overhaul interval (e.g., month 12, 24, etc.).
|
|
||||||
* **$C_{Preventive}$**: The cost of a planned overhaul (materials, labor, and procurement).
|
|
||||||
* **$C_{Corrective}$**: The cost of an unplanned failure (repairs + risk cost of downtime).
|
|
||||||
* **$E[N(T)]$**: The expected number of failures occurring in the interval $(0, T]$. This is derived from the **NHPP (Non-Homogeneous Poisson Process)** reliability model.
|
|
||||||
|
|
||||||
## 2. The Cost Balance (The "U-Curve")
|
|
||||||
Optimization works by balancing two competing costs:
|
|
||||||
1. **Overhaul Cost ($C_{PM}/T$)**: As the interval $T$ increases, the amortized cost of the overhaul decreases (economy of waiting).
|
|
||||||
2. **Failure Risk ($C_{CM} \cdot E[N(T)]/T$)**: As the interval $T$ increases, the probability and expected frequency of failure increase (cost of wear-out).
|
|
||||||
|
|
||||||
The point where these two lines intersect typically represents the **Global Minimum** of the total cost curve, known as the **Optimum Overhaul Month**.
|
|
||||||
|
|
||||||
## 3. Implementation Logic
|
|
||||||
In the `service.py` engine, the search is performed as follows:
|
|
||||||
|
|
||||||
1. **Failure Projection**: The system fetches reliability prediction data (cumulative failures) for the analysis window.
|
|
||||||
2. **Sparepart Simulation**: For every potential month $T$, the system simulates the procurement process to calculate the real $C_{Preventive}$ (including any shortage penalties).
|
|
||||||
3. **Cost Amortization**:
|
|
||||||
```python
|
|
||||||
total_cycle_cost = total_expected_failure_cost + total_preventive_cost
|
|
||||||
cput = total_cycle_cost / month_index
|
|
||||||
```
|
|
||||||
4. **Grid Search**: The system iterates through all months in the analysis window and identifies the index with the lowest `cput` value.
|
|
||||||
|
|
||||||
## 4. Interpretation in UI
|
|
||||||
* **Analysis Window Card**: Shows the CPUT value at your currently selected month.
|
|
||||||
* **Optimum Target Card**: Shows the month $T$ where the curve is at its lowest point.
|
|
||||||
* **Potential Benefit**: Calculated as $CPUT(current) - CPUT(optimum)$. This represents the real monthly cash-flow saving if the maintenance interval is adjusted.

# Plant Level Overhaul Optimization
|
|
||||||
|
|
||||||
This document explains how individual asset optimizations are aggregated to find the best economic strategy for the entire fleet or plant.
|
|
||||||
|
|
||||||
## 1. Fleet Aggregation Theory
|
|
||||||
At the plant level, the objective is to minimize the **Total Fleet Cost per Unit Time**. This assumes a **Uniform Interval Policy** or a **Synchronized Overhaul Strategy** where the plant looks for a common maintenance rhythm.
|
|
||||||
|
|
||||||
### Plant Objective Function
|
|
||||||
The plant-level cost function is the summation of individual equipment cost functions ($C_i$):
|
|
||||||
|
|
||||||
$$C_{Plant}(T) = \sum_{i=1}^{N} C_i(T) = \frac{\sum_{i=1}^{N} (C_{p,i} + C_{f,i} \cdot E[N_i(T)])}{T}$$
|
|
||||||
|
|
||||||
Where:
|
|
||||||
* **$N$**: Total number of equipments in the scope.
|
|
||||||
* **$C_{p,i}$**: Preventive cost for equipment $i$.
|
|
||||||
* **$C_{f,i}$**: Failure cost for equipment $i$.
|
|
||||||
* **$E[N_i(T)]$**: Expected failures for equipment $i$ until time $T$.
|
|
||||||
|
|
||||||
## 2. Searching for the Fleet Optimum
|
|
||||||
The "actual theory" used by the engine involves a two-phase search:
|
|
||||||
|
|
||||||
### Phase 1: Unconstrained Summation
|
|
||||||
The system calculates the CPUT curve for every piece of equipment independently. It then sums these curves to create a "Fleet U-Curve." The minimum of this sum represents the **Theoretical Fleet Optimum**.
|
|
||||||
|
|
||||||
### Phase 2: Sparepart Interaction & Constraints
|
|
||||||
Unlike a simple sum, the real plant optimum must account for **shared resources** (e.g., a limited budget or limited spare parts).
|
|
||||||
1. **Sparepart Conflicts**: If multiple equipments reach their optimal interval at the same time, the `SparepartManager` checks if there are enough parts in the warehouse.
|
|
||||||
2. **Constraint Penalty**: If parts are missing, a "Procurement Penalty" is added to the $C_{p,i}$ for that specific month, effectively shifting the "U-curve" to the right (delaying) or left (earlier) depending on availability.
|
|
||||||
3. **Final Selection**: The system chooses the Month $T$ that minimizes the *constrained* total fleet cost.
|
|
||||||
|
|
||||||
## 3. Implementation in `service.py`
|
|
||||||
The code uses `numpy` to perform vector addition of the cost curves:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Aggregate amortized costs for fleet analysis
|
|
||||||
total_corrective_costs += np.array(corrective_costs)
|
|
||||||
total_preventive_costs += np.array(preventive_costs)
|
|
||||||
total_costs += np.array(total_costs_equipment)
|
|
||||||
|
|
||||||
# Find the month T that minimizes the sum
|
|
||||||
fleet_optimal_index = np.argmin(total_costs)
|
|
||||||
```
|
|
||||||
|
|
||||||
## 4. Key Metrics for Decision Makers
|
|
||||||
* **Fleet CPUT**: The average monthly budget required to maintain the plant at the chosen interval.
|
|
||||||
* **Accumulation Control**: By using amortized costs (Rp/Month) instead of total cumulative costs, the plant chart remains stable and allows for direct comparison between intervals regardless of the number of assets.
|
|
||||||
* **Risk vs. Cost**: The plant chart shows the trade-off between the *Fleet Failure Risk* (increasing line) and *Fixed Overhaul Costs* (decreasing line).
