MAVF_sensitivity: Multi-attribute value function sensitivity analysis

In KraljicMatrix: A Quantified Implementation of the Kraljic Matrix

Description

MAVF_sensitivity computes summary statistics for multi-attribute value scores of x and y given a range of swing weights for each attribute

Usage

MAVF_sensitivity(data, x, y, x_wt_min, x_wt_max, y_wt_min, y_wt_max)

Arguments

data	A data frame
x	Variable from data frame to represent x attribute values
y	Variable from data frame to represent y attribute values
x_wt_min	Lower bound anchor point for x attribute swing weight
x_wt_max	Upper bound anchor point for x attribute swing weight
y_wt_min	Lower bound anchor point for y attribute swing weight
y_wt_max	Upper bound anchor point for y attribute swing weight

Details

The sensitivity analysis performs a Monte Carlo simulation with 1000 trials for each product or service (row). Each trial randomly selects a weight from a uniform distribution between the lower and upper bound weight parameters and calculates the mult-attribute utility score. From these trials, summary statistics for each product or service (row) are calculated and reported for the final output.

Value

A data frame with added variables consisting of sensitivity analysis summary statistics for each product or service (row).

Examples

# Given the following data frame that contains \code{x} and \code{y} attribute
# values for each product or service contract, we can compute how the range of
# swing weights for each \code{x} and \code{y} attribute influences the multi-
# attribute value score.

df <- data.frame(contract = 1:10,
                 x_attribute = c(0.92, 0.79, 1.00, 0.39, 0.68, 0.55, 0.73, 0.76, 1.00, 0.74),
                 y_attribute = c(0.52, 0.19, 0.62, 1.00, 0.55, 0.52, 0.53, 0.46, 0.61, 0.84))

MAVF_sensitivity(df, x_attribute, y_attribute, .55, .75, .25, .45)
