About this Package

An R package to model complex decision making problems using AHP (Analytic Hierarchy Process).

The basic workflow with this package is:

1. specify your ahp problem in an ahp file
2. load ahp file, using LoadFile
3. calculate model, using Calculate
4. output model analysis, either using GetDataFrame or using ShowTable

For more information, see the package vignette using vignette("AHP car example")

There is also a Shiny app that complements that package. You can try it out at http://ipub.com/apps/ahp/

Example

devtools::install_github("gluc/ahp", build_vignettes = TRUE)
vignette("car-example", package = "ahp")
vignette("multiple-decisionmakers", package = "ahp")

# run analysis
library(ahp)
ahpFile <- system.file("extdata", "car.ahp", package="ahp")
carAhp <- Load(ahpFile)
Calculate(carAhp)
Visualize(carAhp)
Analyze(carAhp)
AnalyzeTable(carAhp)

# looking at the vacation example, a multi-decision-maker model
ahpFile <- system.file("extdata", "vacation.ahp", package="ahp")
vacationAhp <- Load(ahpFile)
Calculate(vacationAhp)
Analyze(vacationAhp, decisionMaker = "Dad")
AnalyzeTable(vacationAhp, decisionMaker = "Mom")
AnalyzeTable(vacationAhp)

To play around with the package, you may want to run the Shiny GUI that comes with the package:

RunGUI()

To play around with the example files in your dev environment, you may want to copy them out of the lib path, e.g. like so:

# On Windows
file.copy(ahpFile, "C:\\tmp")

# Or, on Linux:
file.copy(ahpFile, "~")

Then, open them in the text editor of your choice, and modify them. To run the analysis, do, for instance:

myVacation <- LoadFile("C:\\tmp\\vacation.ahp")

NOTE:

The latest from github dev branch may have some breaking changes compared to CRAN. See NEWS for details.
