Business Configuration Design: 
Our system separates business logic design from value determination:
- Configuration Logic (business_configuration_logic.json): Templates designed by data engineers with sample_value for scalars and actual formulas for business logic
- Configuration Values (business_configuration.json): Realistic values determined by domain experts for scalar parameters only
- Design Rationale: Ensures business logic consistency while allowing flexible parameter tuning

# Complete Optimization Problem and Solution: store_product

## 1. Problem Context and Goals

### Context  
A retail chain is focused on optimizing the allocation of products across its stores to maximize total sales revenue. The key decision involves determining the number of units of each product to allocate to each store. This decision must consider the sales potential of each product in each store, the total available units of each product, and the capacity of each store to handle inventory. Additionally, the allocation must adhere to business-defined thresholds: a minimum number of units must be allocated to ensure product presence in every store, and a maximum number of units must not be exceeded to prevent overstocking and maintain balanced inventory levels.

The sales potential of a product in a store represents the expected contribution of that product to total sales revenue. The total sales revenue is calculated by summing the product of the sales potential and the allocated units for each product-store combination. The business configuration includes a minimum allocation threshold of 10 units and a maximum allocation threshold of 100 units per product per store. These thresholds ensure operational efficiency and inventory balance across the retail chain.

### Goals  
The primary goal of this optimization is to maximize total sales revenue by strategically allocating products to stores. This is achieved by determining the optimal number of units of each product to allocate to each store, considering their sales potential, availability, and store capacities. Success is measured by the total sales revenue generated, which is directly influenced by the sales potential of each product in each store and the number of units allocated. The optimization ensures that the allocation respects store capacities, product availability, and the defined minimum and maximum allocation thresholds.

## 2. Constraints  

The optimization must adhere to the following constraints:  
1. **Store Capacity Constraint**: The total number of units allocated to a store across all products must not exceed the store's capacity. This ensures that the store can handle the allocated inventory without operational strain.  
2. **Product Availability Constraint**: The total number of units allocated for a product across all stores must not exceed the available units of that product. This ensures that the allocation does not exceed the available inventory.  
3. **Minimum Allocation Threshold**: The number of units allocated for a product to a store must be at least the minimum allocation threshold. This ensures a minimum presence of each product in every store.  
4. **Maximum Allocation Threshold**: The number of units allocated for a product to a store must not exceed the maximum allocation threshold. This prevents overstocking and ensures balanced inventory levels across stores.  

These constraints ensure that the allocation decisions are operationally feasible and aligned with business requirements.
