Pert

Pert is a command line tool built to assist in the process of creating pert diagrams and calculating permitted delays.

Installation

Make sure you have node and npm installed and working

From git

• clone this repo
• run npm install in the root of the repo, then run bower install in client/ if you need to use the Web GUI
• run npm run-script build to compile all files
• the binary should now be in bin/pert

From npm

• npm install -g pert
• run pert in your shell

Usage

Usage: pert <command> [options] [args]

loads activity data from JSON and computes the possible activity delays

Commands:

  example                       show an example of the JSON data format
  calculate|c [options] <file>  calculate data on given JSON document
  graph|g <file>                serve HTTP GUI with pert graph of given JSON document

Options:

  -h, --help     output usage information
  -V, --version  output the version number
  -v, --verbose  be verbose (for debugging)

This is the help information for the pert calculate command:

Usage: calculate|c [options] <file>

calculate data on given JSON document

Options:

  -h, --help  output usage information
  -j, --json  output json data

Data format

This is a valid input document (extra data is ignored but not thrashed):

[
  {"id": 0, "duration": 3},
  {"id": 1, "duration": 1},
  {"id": 2, "duration": 2, "depends": [0]},
  {"id": 3, "duration": 5, "depends": [1]},
  {"id": 4, "duration": 5, "depends": [1]},
  {"id": 5, "duration": 2, "depends": [2,3,4]}
]

And this is the output of the calculate command on the previous document using the --json flag:

[{"id":0,"duration":3,"startDay":0,"endDay":3,"permittedDelay":0},{"id":1,"duration":1,"startDay":0,"endDay":1,"permittedDelay":0},{"id":2,"duration":2,"depends":[0],"startDay":3,"endDay":5,"permittedDelay":1},{"id":3,"duration":5,"depends":[1],"startDay":1,"endDay":6,"permittedDelay":0},{"id":4,"duration":5,"depends":[1],"startDay":1,"endDay":6,"permittedDelay":0},{"id":5,"duration":2,"depends":[2,3,4],"startDay":6,"endDay":8}]
