 We envision GDPlib as an open library of GDP models to provide examples for prospective modelers, and to provide a benchmarking set for algorithm developers.
 We invite contributions to this library from the community, provided under the same BSD-3-clause or compatible license.

 ## Model Size Example
 
-Here's an example of model size metrics for the Jobshop model:

-### Handling Multiple Cases
-
-Many models in GDPlib support multiple cases or configurations. Here are some examples:
-
-1. **Jobshop Scheduling with Different Problem Sizes**:
-```python
-from gdplib.jobshop import build_model
-# Default case
-model = build_model()
-# Custom case with specific number of jobs and machines
-model = build_model(num_jobs=4, num_machines=3)
-```
-
-2. **Water Network with Different Configurations**:
-```python
-from gdplib.water_network import build_model
-# Default network configuration
-model = build_model()
-# Custom configuration with specific parameters
-model = build_model(
-    num_sources=3,
-    num_sinks=4,
-    treatment_options=['RO', 'NF', 'UF']
-)
-```
-
-3. **Batch Processing with Different Products**:
-```python
-from gdplib.batch_processing import build_model
-# Default product mix
-model = build_model()
-# Custom product mix with specific processing times
-model = build_model(
-    products=['A', 'B', 'C'],
-    processing_times={
-        'A': {'mixing': 2, 'reaction': 3, 'separation': 1},
-        'B': {'mixing': 1, 'reaction': 4, 'separation': 2},
-        'C': {'mixing': 3, 'reaction': 2, 'separation': 2}
-    }
-)
-```
-
-Each model's README.md file contains detailed information about available parameters and their effects on the model behavior.
