What Friendly Sam is for
Why build another tool?
Data handling is easier with Python
Domain specific toolbox
What Friendly Sam is not
OK, let’s get started!
Variables and expressions
Names don’t mean anything
VariableCollection is like an indexed Variable
Variables can have values
Expressions are immutable
Behind
value
is
evaluate()
Optimization problems
Creating a problem
Debugging constraints
Different ways to add constraints
Special ordered sets
Model basics: Parts and constraints
Interconnected parts
Parts have indexed constraints
Advanced indexing
Flow networks: Nodes and resources
Nodes and balance constraints
An example
Balance constraints
How balance constraints are made
Custom names
FlowNetwork
Unidirectional by default
Flow restrictions
Clusters and multi-area models
A cluster is fully connected
Multi-area models
Time in flow networks
Example model
