# Monte Carlo Project Scheduler (mcps)
|
|
|
|
Monte Carlo Project Scheduler (mcps) is a command-line tool that runs Monte
|
|
Carlo simulations on project schedules to estimate completion times and effort
|
|
required. It helps project managers and engineers gain a better understanding of
|
|
potential project risks and timelines by providing a probabilistic analysis of
|
|
schedule durations and total work effort.
|
|
|
|
## Features
|
|
|
|
- **Simulate Project Schedules**: Run multiple simulations to estimate the
|
|
probability distribution of project completion times and total work effort.
|
|
- **Customizable Inputs**: Accepts project schedules in YAML or JSON formats,
|
|
with options to override certain parameters like the number of workers or the
|
|
number of iterations.
|
|
- **Visual Output**: Generates an ASCII-based cumulative distribution function
|
|
(CDF) graph, providing an easy-to-understand visualization of the simulation
|
|
results.
|
|
|
|
## Installation
|
|
|
|
### Prerequisites
|
|
|
|
You'll need to have Rust installed on your system to build the project. You can
|
|
install Rust using `rustup`:
|
|
|
|
```bash
|
|
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
|
```
|
|
|
|
### Building from Source
|
|
|
|
_Preferred_: Install directly from crates.io:
|
|
|
|
```bash
|
|
cargo install mcps
|
|
```
|
|
|
|
_Alternative_: Clone and build the repository locally:
|
|
|
|
```bash
|
|
git clone <git@git.sr.ht>:~swaits/mcps
|
|
cd mcps
|
|
cargo build --release
|
|
```
|
|
|
|
The binary will be available at `target/release/mcps`.
|
|
|
|
## Usage
|
|
|
|
Once you have built the tool, you can use it by providing a project schedule
|
|
file in YAML or JSON format.
|
|
|
|
### Basic Usage
|
|
|
|
```bash
|
|
mcps example.yaml -i 100000 -w 10
|
|
```
|
|
|
|
This command runs the Monte Carlo simulation on the `example.yaml` schedule file
|
|
with 100,000 iterations and overrides the number of workers to 10.
|
|
|
|
### Command-Line Options
|
|
|
|
- `-i, --iterations <iterations>`: Specify the number of iterations to run. Must be at least 100. Default is 50,000.
|
|
- `-w, --workers <num_workers>`: Override the number of workers specified in the schedule file.
|
|
- `-v, --version`: Print version information.
|
|
- `-h, --help`: Print help information.
|
|
|
|
### Schedule File Format
|
|
|
|
The tool accepts schedule files in YAML or JSON format. Below is an example of the YAML format:
|
|
|
|
```yaml
|
|
num_workers: 5 # for the purpose of scheduling simulation
|
|
estimate_confidence: 0.80 # confidence actuals will fall inside estimate bounds
|
|
tasks:
|
|
- id: DesignPhase
|
|
min_time: 1.5 # 1.5 days
|
|
max_time: 3.5 # 3.5 days
|
|
dependencies: []
|
|
- id: ImplementationPhase
|
|
min_time: 2.25 # 2.25 days
|
|
max_time: 4.75 # 4.75 days
|
|
dependencies: [DesignPhase]
|
|
```
|
|
|
|
### Example Output
|
|
|
|
The tool generates an ASCII-based cumulative distribution function (CDF) graph,
|
|
which visually represents the distribution of project durations and effort:
