## 🎯 Quick Deployment (3 Steps)
|
||||||
|
|
||||||
|
### Step 1: Extract Archive
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tar -xzf rollcalc_v14_complete_final.tar.gz
|
||||||
|
cd rollcalc_files/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 2: Run Deployment Script
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Make executable (first time only)
|
||||||
|
chmod +x deploy_rollcalc.py
|
||||||
|
|
||||||
|
# Run deployment
|
||||||
|
python3 deploy_rollcalc.py /path/to/your/flask/root/
|
||||||
|
|
||||||
|
# Example:
|
||||||
|
python3 deploy_rollcalc.py /home/user/rollcalc/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 3: Update Configuration
|
||||||
|
|
||||||
|
Edit `app.py` (in your Flask root) and update passwords:
|
||||||
|
|
||||||
|
```python
|
||||||
|
BETA_USERS = {
|
||||||
|
"beta": "CHANGE_THIS_PASSWORD",
|
||||||
|
"mtazl": "CHANGE_THIS_PASSWORD",
|
||||||
|
"cniehues": "CHANGE_THIS_PASSWORD",
|
||||||
|
# ... etc
|
||||||
|
}
|
||||||
|
|
||||||
|
ADMIN_USERS = {
|
||||||
|
"admin": "CHANGE_THIS_ADMIN_PASSWORD"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Then run:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd /path/to/your/flask/root/
|
||||||
|
python app.py
|
||||||
|
```
|
||||||
|
|
||||||
|
Open: **http://localhost:5000**
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 📋 What the Deployment Script Does
|
||||||
|
|
||||||
|
The `deploy_rollcalc.py` script automates everything:
|
||||||
|
|
||||||
|
✅ Creates required directories
|
||||||
|
✅ Backs up existing files
|
||||||
|
✅ Deploys all files to correct locations
|
||||||
|
✅ Verifies Python dependencies
|
||||||
|
✅ Checks for default passwords
|
||||||
|
✅ Validates all files after deployment
|
||||||
|
✅ Prints clear next steps
|
||||||
|
|
||||||
|
**No manual copying needed!**
|
||||||
|
|

|
||||||
|
|
||||||
|
## ⚠️ Important: article-data.json
|
||||||
|
|
||||||
|
The archive contains a **placeholder** for `article-data.json`.
|
||||||
|
|
||||||
|
**You need to add your product data:**
|
||||||
|
|
||||||
|
### Option A: Import from Existing System
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# If you already have article-data.json:
|
||||||
|
cp /path/to/your/article-data.json /path/to/flask/static/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Option B: Use Minimal Data for Testing
|
||||||
|
|
||||||
|
The placeholder is already there - you can test the calculator without product data.
|
||||||
|
|
||||||
|
### Option C: Generate from ERP
|
||||||
|
|
||||||
|
Update the export script in your ERP system to create article-data.json format:
|
||||||
|
|
||||||
|
```json
|
||||||
|
[
|
||||||
|
{
|
||||||
|
"nr": "180005",
|
||||||
|
"name": "Bfix NSP 4000, 5,00 x 50 m",
|
||||||
|
"thickness": 6.228,
|
||||||
|
"thickness_stddev": 0.379,
|
||||||
|
"area_weight": 3899.02,
|
||||||
|
"area_weight_stddev": 133.24,
|
||||||
|
"core_type": 0.0,
|
||||||
|
...
|
||||||
|
}
|
||||||
|
]
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 🛠️ Manual Deployment (If Script Fails)
|
||||||
|
|
||||||
|
If the Python script doesn't work, deploy manually:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Extract
|
||||||
|
tar -xzf rollcalc_v14_complete_final.tar.gz
|
||||||
|
|
||||||
|
# Backend
|
||||||
|
cp rollcalc_files/app.py /path/to/flask/
|
||||||
|
|
||||||
|
# Static files
|
||||||
|
cp rollcalc_files/*.js /path/to/flask/static/
|
||||||
|
cp rollcalc_files/*.json /path/to/flask/static/
|
||||||
|
|
||||||
|
# Documentation
|
||||||
|
mkdir -p /path/to/flask/docs
|
||||||
|
cp rollcalc_files/*.md /path/to/flask/docs/
|
||||||
|
cp rollcalc_files/*.html /path/to/flask/docs/
|
||||||
|
|
||||||
|
# Run
|
||||||
|
cd /path/to/flask/
|
||||||
|
python app.py
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## ✅ Verification Checklist
|
||||||
|
|
||||||
|
After deployment, verify:
|
||||||
|
|
||||||
|
- [ ] `app.py` in Flask root
|
||||||
|
- [ ] `service-worker.js` in `/static/`
|
||||||
|

|
||||||
|
- [ ] `article-data.json` in `/static/` (with real data)
|
||||||
|
- [ ] `config.json` in `/static/`
|
||||||
|
- [ ] `templates/roll_calculator.html` exists (add 2 script tags for StdDev)
|
||||||
|
- [ ] Passwords updated in `app.py`
|
||||||
|
- [ ] Server runs: `python app.py`
|
||||||
|
- [ ] Page loads: `http://localhost:5000`
|
||||||
|
- [ ] Login works (use credentials from `BETA_USERS`)

## 🎨 HTML Integration (StdDev Ranges)
|
||||||
|
|
||||||
|
If you want to use the **Standard Deviation Ranges** feature, add to your `roll_calculator.html` in the `<head>` section:
|
||||||
|
|
||||||
|
```html
|
||||||
|
<!-- Add these two lines: -->
|
||||||
|
<script src="/static/rollcalc-stddev-ranges.js"></script>
|
||||||
|
<script src="/static/rollcalc-stddev-integration.js"></script>
|
||||||
|
|
||||||
|
<!-- Also add this to your Direct Calc form: -->
|
||||||
|
<!-- (Details in STDDEV_IMPLEMENTATION_CHECKLIST.md) -->
|
||||||
|
```
|
||||||
|
|
||||||

## 🆘 Troubleshooting
|
||||||
|
|
||||||
|
### "Deploy script fails: Missing dependencies"
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install flask flask-httpauth
|
||||||
|
```
|
||||||
|
|
||||||
|
### "Page won't load at localhost:5000"
|
||||||
|
|
||||||
|
1. Check Flask is running: `python app.py`
|
||||||
|
2. Check port 5000 is free
|
||||||
|
3. Check firewall allows localhost:5000
|
||||||
|
|
||||||
|
### "Login prompt appears but password doesn't work"
|
||||||
|
|
||||||
|
1. Check `BETA_USERS` in `app.py` - use those credentials
|
||||||
|
2. Username: `mtazl`, Password: `rollcalc` (default)
|
||||||
|
3. Change to your custom passwords
|
||||||
|
|
||||||
|
### "Article dropdown is empty"
|
||||||
|
|
||||||
|
1. Check `article-data.json` exists in `/static/`
|
||||||
|
2. Check it has valid JSON format
|
||||||
|
3. Refresh browser (Ctrl+F5 or Cmd+Shift+R)
|
||||||
|
4. Check browser console (F12) for errors
|
||||||
|
|
||||||
|
### "Service Worker not working"
|
||||||
|
|
||||||
|
1. Clear browser cache (Ctrl+Shift+Delete)
|
||||||
|
2. Hard refresh (Ctrl+Shift+F5)
|
||||||
|
3. Check DevTools → Application → Service Workers
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
**Questions?** Check the documentation files in `/docs/`
|
||||||
|
|
||||||
|
**Issues?** Look in browser console (F12) for error messages

||||||
|
**Success indicators:**
|
||||||
|
- ✅ Page loads at localhost:5000
|
||||||
|

## 🎯 THE FEATURE: ±2σ Standard Deviation Ranges
|
||||||
|
|
||||||
|
### What It Does
|
||||||
|
|
||||||
|
**Before:**
|
||||||
|
```
|
||||||
|
Roll Diameter (D)
|
||||||
|
502.8 mm
|
||||||
|
```
|
||||||
|
|
||||||
|
**After:**
|
||||||
|
```
|
||||||
|
Roll Diameter (D)
|
||||||
|
502.8 mm
|
||||||
|
|
||||||
|
Range (±2σ): 491.2 – 514.4 mm
|
||||||
|
```
|
||||||
|
|
||||||
|
### Where It's Used
|
||||||
|
|
||||||
|
| Component | Data | Range |
|
||||||
|
|-----------|------|-------|
|
||||||
|
| **Direct Calc** | ✅ Shows MIN/NOM/MAX | ±2σ (95% confidence) |
|
||||||
|
| **Forklift Checker** | ✅ Uses WORST-CASE | Maximum weight |
|
||||||
|
| **Load Optimizer** | ✅ Uses NOMINAL | No change |
|
||||||
|
|
||||||
|
### What Powers It
|
||||||
|
|
||||||
|
Each product has production variance data:
|
||||||
|
- `thickness_stddev` - How much thickness varies
|
||||||
|
- `area_weight_stddev` - How much area_weight varies
|
||||||
|
|
||||||
|
**Example (Article 180005):**
|
||||||
|
```json
|
||||||
|
{
|

## 📊 CALCULATION FORMULAS
|
||||||
|
|
||||||
|
### Diameter Ranges (±2σ)
|
||||||
|
|
||||||
|
```
|
||||||
|
t_min = thickness - 2×stddev (thinnest)
|
||||||
|
t_nom = thickness (nominal)
|
||||||
|
t_max = thickness + 2×stddev (thickest)
|
||||||
|
|
||||||
|
D_min = √(d² + 4×L×t_min/π) (largest roll)
|
||||||
|
D_nom = √(d² + 4×L×t_nom/π) (nominal)
|
||||||
|
D_max = √(d² + 4×L×t_max/π) (smallest roll)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Key Insight:** Thinner product → Larger roll (counterintuitive!)
|
||||||
|
|
||||||
|
### Weight Ranges (±2σ)
|
||||||
|
|
||||||
|
```
|
||||||
|
aw_min = area_weight - 2×stddev (lightest)
|
||||||
|
aw_nom = area_weight (nominal)
|
||||||
|
aw_max = area_weight + 2×stddev (heaviest)
|
||||||
|
|
||||||
|
Weight = aw × Length × Width / 1000
|
||||||
|
```
|
||||||

|
## 🛠️ QUICK IMPLEMENTATION (15 minutes)
|
||||||
|
|
||||||
|
### Step 1: Add Script Tags (2 lines)
|
||||||
|
```html
|
||||||
|
<script src="/static/rollcalc-stddev-ranges.js"></script>
|
||||||
|
<script src="/static/rollcalc-stddev-integration.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 2: Store StdDev (6 lines)
|
||||||
|
Add to article selection handler:
|
||||||
|
```javascript
|
||||||
|
document.getElementById('d-th').dataset.stddev = match.thickness_stddev || 0;
|
||||||
|
document.getElementById('d-aw').dataset.stddev = match.area_weight_stddev || 0;
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 3: Update Diameter Calc (2 lines)
|
||||||
|
```javascript
|
||||||
|
const result = window.StdDevIntegration.calculateDiameterWithStddev(...);
|
||||||
|
const weightRanges = window.StdDevIntegration.calcWeightWithStddev(...);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 4: Update Forklift Check (1 line)
|
||||||
|
```javascript
|
||||||
|
window.StdDevIntegration.evaluateForkliftWithWorstCase(d_mm, category);
|
||||||
|
```
|
||||||
|
|
||||||

# StdDev Ranges Implementation Checklist
|
||||||
|
|
||||||
|
## 📋 Quick Implementation Guide
|
||||||
|
|
||||||
|
### Phase 1: Add JavaScript Modules (2 files)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Copy to your static folder:
|
||||||
|
cp .code/rollcalc-stddev-ranges.js /path/to/flask/static/
|
||||||
|
cp .code/rollcalc-stddev-integration.js /path/to/flask/static/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase 2: Update HTML (3 lines changed)
|
||||||
|
|
||||||
|
In `roll_calculator.html`, find the section where scripts are loaded (around line ~2370):
|
||||||
|
|
||||||
|
**Add after the other script tags:**
|
||||||
|
```html
|
||||||
|
<script src="/static/rollcalc-stddev-ranges.js"></script>
|
||||||
|
<script src="/static/rollcalc-stddev-integration.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase 3: Update JavaScript - Article Selection
|
||||||
|
|
||||||
|
In `rollcalc_improvements.js`, find the `populateArticleDropdowns_v14()` function.
|
||||||
|
|
||||||
|
In the "DirectCalc-Article" section (~line 2340), after the existing article fill code:
|
||||||
|
|
||||||
|
**ADD THESE LINES:**
|
||||||
|
```javascript
|
||||||
|
// NEW: Store stddev values for later use
|
||||||
|
document.getElementById('d-th').dataset.stddev = match.thickness_stddev || 0;
|
||||||
|
document.getElementById('d-aw').dataset.stddev = match.area_weight_stddev || 0;
|
||||||
|
|
||||||
|
console.log('[StdDev] Stored:', {
|
||||||
|
thickness_stddev: match.thickness_stddev,
|
||||||
|
area_weight_stddev: match.area_weight_stddev
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase 4: Update Direct Calc Button Handler
|
||||||
|
|
||||||
|
**FIND:** The diameter calculation section in the `d-calc` click handler (~line 2380)
|
||||||
|
|
||||||
|
**Replace this block:**
|
||||||
|
```javascript
|
||||||
|
if (mode === 'diameter') {
|
||||||
|
if (!d_mm || !t_mm || !L_m) { alert('Please enter d, t and L.'); return; }
|
||||||
|
const D_nom = Math.sqrt(d_mm*d_mm + (4*L_m*1000*t_mm)/Math.PI);
|
||||||
|
resLabel.textContent = 'Roll Diameter (D)';
|
||||||
|
resVal.textContent = D_nom.toFixed(1) + ' mm';
|
||||||
|
if (tol) {
|
||||||
|
const D_min = Math.sqrt(d_mm*d_mm + (4*L_m*1000*(t_mm-tol))/Math.PI);
|
||||||
|
const D_max = Math.sqrt(d_mm*d_mm + (4*L_m*1000*(t_mm+tol))/Math.PI);
|
||||||
|
resRange.textContent = 'Min: ' + D_min.toFixed(1) + ' mm | Max: ' + D_max.toFixed(1) + ' mm';
|
||||||
|
} else { resRange.textContent = ''; }
|
||||||
|
document.getElementById('d-di').value = D_nom.toFixed(1);
|
||||||
|
calculatedLength = L_m;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**WITH THIS:**
|
||||||
|
```javascript
|
||||||
|
if (mode === 'diameter') {
|
||||||
|
const result = window.StdDevIntegration.calculateDiameterWithStddev(d_mm, t_mm, null, L_m, tol);
|
||||||
|
if (!result) return;
|
||||||
|
|
||||||
|
calculatedLength = result.calculatedLength;
|
||||||
|
|
||||||
|
// Calculate weight with stddev ranges
|
||||||
|
const weightRanges = window.StdDevIntegration.calcWeightWithStddev(calculatedLength);
|
||||||
|
|
||||||
|
// Forklift check uses worst-case weight
|
||||||
|
window.StdDevIntegration.evaluateForkliftWithWorstCase(d_mm, category);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase 5: Update Weight Calculation
|
||||||
|
|
||||||
|
**FIND:** The `calcWeight()` function (~line 2410)
|
||||||
|
|
||||||
|
**Replace:**
|
||||||
|
```javascript
|
||||||
|
function calcWeight(length) {
|
||||||
|
const wi = parseFloat(document.getElementById('de-wi').value) || 0;
|
||||||
|
const aw = parseFloat(document.getElementById('d-aw').value) || 0;
|
||||||
|
if (wi > 0 && aw > 0 && length > 0) {
|
||||||
|
const w = (aw * length * wi / 1000).toFixed(1);
|
||||||
|
document.getElementById('d-wo').value = w;
|
||||||
|
return parseFloat(w);
|
||||||
|
}
|
||||||
|
document.getElementById('d-wo').value = '';
|
||||||
|
return null;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**WITH:**
|
||||||
|
```javascript
|
||||||
|
function calcWeight(length) {
|
||||||
|
return window.StdDevIntegration.calcWeightWithStddev(length);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase 6: Update Forklift Check Call
|
||||||
|
|
||||||
|
**FIND:** The line that calls `ForkliftChecker.evaluate()` (~line 2420)
|
||||||
|
|
||||||
|
**Change from:**
|
||||||
|
```javascript
|
||||||
|
const allowed = runForkliftCheck(weight);
|
||||||
|
```
|
||||||
|
|
||||||
|
**TO:**
|
||||||
|
```javascript
|
||||||
|
const allowed = window.StdDevIntegration.evaluateForkliftWithWorstCase(d_mm, category);
|
||||||
|
```
|
||||||
|
|

## 🐛 Debugging
|
||||||
|
|
||||||
|
If something doesn't work:
|
||||||
|
|
||||||
|
1. **Open DevTools (F12) → Console**
|
||||||
|
2. **Look for these logs:**
|
||||||
|
- `[StdDev] Stored:` - Article stddev loaded?
|
||||||
|
- `[StdDev-Calc] Diameter with ranges:` - Calculation done?
|
||||||
|
- `[StdDev-Weight] Calculated ranges:` - Weight ranges set?
|
||||||
|
- `[StdDev-Forklift] Using worst-case weight:` - Forklift using right value?
|
||||||
|
|
||||||
|
3. **Common issues:**
|
||||||
|
- Missing script tags → Add to HTML `<head>`
|
||||||
|
- Article without stddev → Should default to 0
|
||||||
|
- Functions undefined → Check script load order
|
||||||
|
- Wrong values → Check browser cache (Ctrl+Shift+Delete)
|
||||||

# RollCalc V14 - Quality of Life Update: Standard Deviation Ranges
|
||||||
|
|
||||||
|
## 🎯 Feature Overview
|
||||||
|
|
||||||
|
Add **±2σ (95% confidence intervals)** for Roll Diameter and Roll Weight based on actual production data variance.
|
||||||
|
|
||||||
|
**Implementation:**
|
||||||
|
- **Direct Calculation Tab:** Show MIN/NOM/MAX values
|
||||||
|
- **Forklift Checker:** Use worst-case (maximum) weight
|
||||||
|
- **Load Optimizer:** Use nominal values (no change)
|
||||||
|
|

## 📊 Where Data Comes From
|
||||||
|
|
||||||
|
Each product in `article-data.json` has:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"nr": "180005",
|
||||||
|
"thickness": 6.227909,
|
||||||
|
"thickness_stddev": 0.379181, // ← NEW: Use this
|
||||||
|
"area_weight": 3899.020066,
|
||||||
|
"area_weight_stddev": 133.240428, // ← NEW: Use this
|
||||||
|
...
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Interpretation:**
|
||||||
|
- `thickness ± 2×stddev` = 95% of rolls will be within this range
|
||||||
|
- Same for `area_weight`
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 🧮 Formulas
|
||||||
|
|
||||||
|
### Roll Diameter with ±2σ
|
||||||
|
|
||||||
|
```
|
||||||
|
t_min = thickness - 2×thickness_stddev (thinnest product)
|
||||||
|
t_max = thickness + 2×thickness_stddev (thickest product)
|
||||||
|
|
||||||
|
D_min = √(d² + 4×L×t_min / π) (largest diameter)
|
||||||
|
D_nom = √(d² + 4×L×t_nom / π) (nominal)
|
||||||
|
D_max = √(d² + 4×L×t_max / π) (smallest diameter)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Note:** Thinner product → Larger roll (counterintuitive but correct!)
|
||||||
|
|
||||||
|
### Weight with ±2σ
|
||||||
|
|
||||||
|
```
|
||||||
|
aw_min = area_weight - 2×area_weight_stddev
|
||||||
|
aw_nom = area_weight
|
||||||
|
aw_max = area_weight + 2×area_weight_stddev
|
||||||
|
|
||||||
|
Weight_min = aw_min × Length × Width / 1000
|
||||||
|
Weight_nom = aw_nom × Length × Width / 1000
|
||||||
|
Weight_max = aw_max × Length × Width / 1000
|
||||||
|
```

|
|
||||||
|
## 🛠️ Implementation Steps
|
||||||
|
|
||||||
|
### Step 1: Include New JavaScript Files
|
||||||
|
|
||||||
|
Add to `roll_calculator.html` in `<head>`:
|
||||||
|
|
||||||
|
```html
|
||||||
|
<script src="/static/rollcalc_improvements.js"></script>
|
||||||
|
<script src="/static/rollcalc-stddev-ranges.js"></script>
|
||||||
|
<script src="/static/rollcalc-stddev-integration.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 2: Store StdDev During Article Selection
|
||||||
|
|
||||||
|
In `rollcalc_improvements.js`, update article selection handler:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
if (match) {
|
||||||
|
// ... existing code ...
|
||||||
|
|
||||||
|
// NEW: Store stddev values for later use
|
||||||
|
document.getElementById('d-th').dataset.stddev = match.thickness_stddev || 0;
|
||||||
|
document.getElementById('d-aw').dataset.stddev = match.area_weight_stddev || 0;
|
||||||
|
|
||||||
|
console.log('[StdDev] Stored:', {
|
||||||
|
thickness_stddev: match.thickness_stddev,
|
||||||
|
area_weight_stddev: match.area_weight_stddev
|
||||||
|
});
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 3: Update Direct Calc Button Handler
|
||||||
|
|
||||||
|
Replace the diameter calculation in `d-calc` click handler:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
if (mode === 'diameter') {
|
||||||
|
const result = window.StdDevIntegration.calculateDiameterWithStddev(
|
||||||
|
d_mm, t_mm, null, L_m, tol
|
||||||
|
);
|
||||||
|
if (!result) return;
|
||||||
|
|
||||||
|
const diameterRanges = result.diameterRanges;
|
||||||
|
const calculatedLength = result.calculatedLength;
|
||||||
|
|
||||||
|
// Calculate weight with ranges
|
||||||
|
const weightRanges = window.StdDevIntegration.calcWeightWithStddev(calculatedLength);
|
||||||
|
|
||||||
|
// Forklift check with worst-case
|
||||||
|
window.StdDevIntegration.evaluateForkliftWithWorstCase(d_mm, category);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 4: Update Weight Display
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
function calcWeight(length) {
|
||||||
|
// Use new function that returns ranges
|
||||||
|
return window.StdDevIntegration.calcWeightWithStddev(length);
|
||||||
|
}
|
||||||
|
```

## 🧪 Testing Checklist
|
||||||
|
|
||||||
|
### Test Case 1: Direct Calc with StdDev
|
||||||
|
- [ ] Select article with stddev data
|
||||||
|
- [ ] Verify ranges display in result
|
||||||
|
- [ ] Check formula is correct (min < nom < max for weight)
|
||||||
|
- [ ] Check diameter order is correct (thinner product → larger roll)
|
||||||
|
|
||||||
|
### Test Case 2: Article with Zero StdDev
|
||||||
|
- [ ] Select article with stddev = 0
|
||||||
|
- [ ] Ranges should show: nom = min = max
|
||||||
|
- [ ] System should handle gracefully
|
||||||
|
|
||||||
|
### Test Case 3: Forklift Checker Uses Worst-Case
|
||||||
|
- [ ] Calculate weight with ranges
|
||||||
|
- [ ] Check forklift checker uses weight_max
|
||||||
|
- [ ] Try to trigger warning with worst-case
|
||||||
|
|
||||||
|
### Test Case 4: Load Optimizer Gets Nominal
|
||||||
|
- [ ] Complete calculation with ranges
|
||||||
|
- [ ] Open Load Optimizer
|
||||||
|
- [ ] Verify it uses nominal weight (not max)
|
||||||
|
|
||||||
|
### Test Case 5: Backward Compatibility
|
||||||
|
- [ ] Article data without stddev fields should work
|
||||||
|
- [ ] Default stddev to 0 if missing
|
||||||
|
- [ ] Display should adjust gracefully
|
||||||
|

|
|

|
## 🎯 Confidence Level (±2σ)
|
||||||
|
|
||||||
|
**95% Confidence Interval:**
|
||||||
|
- 95% of all manufactured rolls will fall within MIN/MAX range
|
||||||
|
- 5% of rolls may exceed these bounds (acceptable for manufacturing)
|
||||||
|
|
||||||
|
**Why ±2σ and not ±1σ?**
|
||||||
|
- ±1σ = 68% confidence (too narrow, misses real variation)
|
||||||
|
- ±2σ = 95% confidence (practical for manufacturing planning)
|
||||||
|
- ±3σ = 99.7% confidence (too conservative, unrealistic)
|
||||||

## 🚨 Edge Cases Handled
|
||||||
|
|
||||||
|
| Case | Behavior |
|
||||||
|
|------|----------|
|
||||||
|
| No stddev data | Default to 0, show nom only |
|
||||||
|
| Negative stddev | Clamp to 0 |
|
||||||
|
| stddev > nominal | Allow, shows full realistic range |
|
||||||
|
| Article without match | No ranges calculated |
|
||||||
|
| Missing d-aw field | Weight ranges skipped |
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 📈 Performance Impact
|
||||||
|
|
||||||
|
**New calculations per click:**
|
||||||
|
- 2 square roots (for D_min/max): ~1ms
|
||||||
|
- 2 multiplications (for weight ranges): ~0.1ms
|
||||||
|
- Total per calculation: **~1.1ms** (negligible)
|
||||||
|
|
||||||
|
**Memory footprint:**
|
||||||
|
- 6 new data attributes per article field: **~100 bytes**
|
||||||
|
- JavaScript module size: **~8 KB**
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## ✅ Backward Compatibility
|
||||||
|
|
||||||
|
✅ **100% Backward Compatible**
|
||||||
|
- Existing articles without stddev fields work fine
|
||||||
|
- StdDev defaults to 0 if missing
|
||||||
|
- Old calculations still work
|
||||||
|
- No breaking changes to API or data format

|
||||||
|
## 📞 Questions?
|
||||||
|
|
||||||
|
**What if an article has no stddev data?**
|
||||||
|
→ System defaults stddev to 0, displays nominal value only
|
||||||
|
|
||||||
|
**Can I disable stddev ranges?**
|
||||||
|
→ Set stddev to 0 in article-data.json
|
||||||
|
|
||||||
|
**Does this affect offline mode?**
|
||||||
|
→ No, all calculations happen client-side
|
||||||
|
|
||||||
|
**Can I export the ranges?**
|
||||||
|
→ Add export button to include nom/min/max in output
