investigateUtility: Post factum analysis: check how much utility is missing

Description

This function calculates missing value of an alternative utility for that alternative to be possibly (or necessarily) assigned to at least some specific class.

Usage

investigateUtility(alternative, atLeastToClass, necessary, problem)

Arguments

alternative

An alternative index.

atLeastToClass

An assignment to investigate.

necessary

Whether necessary or possible assignment is considered.

problem

Problem for investigation.

Value

List with named elements:

• ux - value of missing utility,
• solution - result of solving model. It can be used for further computations (getAssignments, getThresholds, getMarginalUtilities, getCharacteristicPoints).

NULL is returned if given assignment is not possible.

Examples

perf <- matrix(c(8, 2, 1, 7, 0.5, 0.9, 0.4, 0.5), ncol = 2)
problem <- buildProblem(perf, 3, FALSE, c('g', 'g'), c(0, 0))
problem <- addAssignmentsUB(problem, c(1, 2), c(2, 3))

result <- investigateUtility(4, 3, FALSE, problem)
