New Optimization Model
Normalization???
unique solutions ???
Objective Function Object
...
| Attribute | Required | Content | Values | Description |
|---|---|---|---|---|
| operator | Y | String | sum, min, max | The operation which will be a part of the objective function |
| operands | Y | List of operand object | The operand on which the operation is to be performed. The operand can be an attribute or result of a function | |
| inverse | N | Boolean | default: False | Flag to specify whether the objective function has to be inverted. |
operand object
| Attribute | Required | Content | Values | Description | ||
|---|---|---|---|---|---|---|
| weightnormalization | N | decimal | default: 1.0 | normalization object | Set of values used to normalize Weight of the operand | |
| operation_function | N | operation function object | ||||
| function | N | String | distance_between, latency_between, attribute | Function to be performed on the parameters | ||
| fucntion_params | N | dict | parameters on which the function will be applied. The parameters will change for each function. |
Examples
1. Minimize an attribute of the demand
Normalization object
| Attribute | Required | Content | Values | Description |
|---|---|---|---|---|
| start | Y | Decimal | Start of the range | |
| end | Y | Decimal | End of the range | |
| weight | N | Decimal | Default: 1.0 | Weight of the objective function |
Examples

normalization:
function(value, function(value, range(start, end), weight)
All ranges are converted to 0 to 1. The inverse operation is not needed , since it is already implied in the range.
normalized value = (value - start) / (end-start)
