inventory_step
Time step of inventory
time_step
Current time step of simulation, built-in attribute that is automatically
updated by the simulator!
iter
Current simulation iteration, built-in attribute that is automatically
updated by the simulator. NB: The iteration variable name cannot be 'iteration' as
that would lead to duplicate columns in SIMO databases!
price_trend_period

Factor used for calculating a reservation price from past prices,
ie. factor 0.1 means that the reservation price is 10% higher than
the past mean price
