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

1. clone this repo and run build.sh
2. run bin/pert

From npm

1. npm install -g pert
2. run pert in your shell

Usage

Usage: pert 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

Options:

  -h, --help     output usage information
  -V, --version  output the version number
  --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:

[
  {"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}]
