Detailed Description

Dataset datastructure.

The AlternativesPerformance class hold the datastructure that implement a complete dataset. An AlternativesPerformance object hold a PerformanceTable that represents the values of each alternative on each vriterion, and a hashmap that stores the ategory assignment for each alternatives. The hashmap is unordered and link the name of an alternative to the Category object to which it is assigned.

Constructor & Destructor Documentation

AlternativesPerformance() [1/4]

AlternativesPerformance::AlternativesPerformance	(	std::vector< std::vector< Perf >> &	perf_vect,
		std::unordered_map< std::string, Category > &	alt_assignment = default_map
	)

AlternativesPerformance standard constructor (PerformanceTable surcharged)

Parameters

perf_vect	Vector of performance
alt_assignment	Map of alternative to the assigned category. Default alternatives assigned to empty categories, but good practice would be to create the AlternativePerformance object with an AlternativeAssignment map, otherwise we should use PerformanceTable instead

AlternativesPerformance() [2/4]

AlternativesPerformance::AlternativesPerformance	(	int	nb_of_perfs,
		Criteria &	crits,
		std::string	prefix = "alt",
		std::unordered_map< std::string, Category > &	alt_assignment = default_map
	)

AlternativesPerformance constructor without perf values but set of criteria to evaluate performance over (PerformanceTable surcharged)

Parameters

nb_of_perfs	Number of performance
crits	Criteria to evaluate performance over
prefix	Prefix to use for the name of each Performance created. Default = "alt"
alt_assignment	Map of alternative to the assigned category. Default alternatives assigned to empty categories, but good practice would be to create the AlternativePerformance object with an AlternativeAssignment map, otherwise we should use PerformanceTable instead

AlternativesPerformance() [3/4]

AlternativesPerformance::AlternativesPerformance	(	const PerformanceTable &	perf_table,
		std::unordered_map< std::string, Category > &	alt_assignment = default_map
	)

AlternativesPerformance constructor using an existing performance table

Parameters

perf_table	Performance table to copy
alt_assignment	Map of alternative assignements to categories Default alternatives assigned to empty categories, but good practice would be to create the AlternativePerformance object with an AlternativeAssignment map, otherwise we should use PerformanceTable instead

AlternativesPerformance() [4/4]
