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: party_people

## 1. Problem Context and Goals

### Context  
A political party is focused on maximizing its influence across various regions by strategically allocating its members to events. The party aims to ensure that each region is adequately represented while keeping the total cost of organizing these events within a predefined budget. The influence in each region is directly proportional to the number of members assigned to events in that region, and the cost is determined by the number of events organized. 

The party has a total budget of 150,000 units available for organizing events, and the cost of organizing a single event in any region is 6,000 units. Each region has specific constraints on the number of members that can be assigned, the minimum and maximum number of events that can be organized, and the minimum number of members that must be assigned. The impact of assigning a member to an event varies by region, as reflected by the influence coefficient for each region.

The key decisions involve determining the number of members to assign to events in each region and the number of events to organize in each region. These decisions must respect the budget, regional member availability, and event organization limits.

### Goals  
The primary goal is to maximize the party's overall influence across all regions. This is achieved by strategically assigning members to events in each region, weighted by the region-specific influence coefficient. Success is measured by the total influence generated, which is the sum of the influence coefficients multiplied by the number of members assigned in each region. The optimization ensures that the total cost of organizing events does not exceed the available budget and that all regional constraints on member assignments and event organization are satisfied.

## 2. Constraints  

The optimization problem is subject to the following constraints:  
1. **Budget Constraint**: The total cost of organizing events across all regions must not exceed the total budget of 150,000 units. The cost per event is 6,000 units.  
2. **Member Assignment Upper Bound**: The number of members assigned to events in each region cannot exceed the total number of members available in that region.  
3. **Member Assignment Lower Bound**: Each region must have at least a minimum number of members assigned to events.  
4. **Event Organization Upper Bound**: The number of events organized in each region cannot exceed the maximum number of events allowed in that region.  
5. **Event Organization Lower Bound**: Each region must organize at least a minimum number of events.  

These constraints ensure that the party's operations are feasible, respect resource limitations, and meet regional requirements.

## 3. Available Data  

### Database Schema  
```sql
-- Iteration 1 Database Schema
-- Objective: Schema changes include creating new tables for decision variables and constraint bounds, and updating business configuration logic for scalar parameters and formulas.

CREATE TABLE region_members (
  region_id INTEGER,
  number_of_members INTEGER
);

CREATE TABLE region_events (
  region_id INTEGER,
  number_of_events INTEGER
);

CREATE TABLE region_constraints (
  region_id INTEGER,
  total_members_available INTEGER,
  max_events INTEGER,
  min_members INTEGER,
  min_events INTEGER,
  influence_coefficient FLOAT
);
```

### Data Dictionary  
- **region_members**:  
  - **region_id**: Unique identifier for the region.  
  - **number_of_members**: Number of members assigned to events in the region. This is a decision variable in the optimization.  

- **region_events**:  
  - **region_id**: Unique identifier for the region.  
  - **number_of_events**: Number of events organized in the region. This is a decision variable in the optimization.  

- **region_constraints**:  
  - **region_id**: Unique identifier for the region.  
  - **total_members_available**: Total number of members available in the region. This serves as an upper bound for member assignments.  
  - **max_events**: Maximum number of events that can be organized in the region. This serves as an upper bound for event organization.  
  - **min_members**: Minimum number of members that must be assigned to the region. This serves as a lower bound for member assignments.  
  - **min_events**: Minimum number of events that must be organized in the region. This serves as a lower bound for event organization.  
  - **influence_coefficient**: Impact of assigning a member to an event in the region. This is used as a coefficient in the objective function to measure influence.
