PlanBee 🐝

If Plan A fails, dont worry there is always PlanBee! PlanBee is a Job Shop Scheduling algorithm module buzzing with features. Feed PlanBee with your tasks and resources and it quickly finds a solution. It employs the high-speed computation power of NumPy to achieve fast results. With PlanBee, Plan B becomes your Plan A!

Features 🚀

• Define your own tasks and resources.
• Specify available windows for each resource.
• Indicate priority, duration, and necessary resources for each task.
• Solve your scheduling problems with a single function call!
• Get a detailed summary and visualization of the scheduling solution.

Installation 🛠️

pip install planbee

Usage 🐍

First, import the necessary modules:

from PlanBee import Resource, Task, Scheduler

Then, define your resources:

resource1 = Resource(id=1, available_windows=[(0, 10), (15, 20)])
resource2 = Resource(id=2, available_windows=[(5, 20)])

And your tasks:

task1 = Task(id=1, duration=5, priority=1, resources=[resource1, resource2], resource_count=1)
task2 = Task(id=2, duration=3, priority=2, resources=[resource1], predecessors=[task1], resource_count=1)

Finally, use the Scheduler to solve:

scheduler = Scheduler(tasks=[task1, task2])
result = scheduler.schedule()

Visualization 📊

PlanBee provides a function to plot your schedule:

result.plot_resource_plan()
