class bw2parameters.parameter_set.ParameterSet(params, global_params=None, interpreter=None)[source]#

Bases: object

basic_validation()[source]#: Basic validation needed to build references and order

evaluate()[source]#: Evaluate each formula. Returns dictionary of parameter names and values.

evaluate_and_set_amount_field()[source]#: Evaluate each formula. Updates the amount field of each parameter.

evaluate_monte_carlo(iterations=1000)[source]#

Evaluate each formula using Monte Carlo and variable uncertainty data, if present.

Formulas must return a one-dimensional array, or BroadcastingError is raised.

Returns dictionary of {parameter name: numpy array}.

get_interpreter(evaluate_first=True)[source]#: Get an instance of asteval.Interpreter that is prepopulated with global and local symbol names and values.

get_order()[source]#: Get a list of parameter name in an order that they can be safely evaluated

get_references()[source]#: Create dictionary of parameter references
