Hi everyone,

I’m happy to announce that my Julia package, **OperationsResearchModels.jl** , is now in a good state!

> **[GitHub - jbytecode/OperationsResearchModels.jl: A Julia package for operations research subjects](https://github.com/jbytecode/OperationsResearchModels.jl)**
>
> A Julia package for operations research subjects

The package includes, but isn’t limited to: the linear transportation problem, the assignment problem, the classical knapsack problem, various network models (Shortest Path, Maximum Flow, Minimum Spanning Tree), project management techniques (CPM and PERT), the uncapacitated p-median problem for location selection, Johnson’s Rule for flow-shop scheduling, a genetic algorithm for scheduling problems intractable by Johnson’s Rule, a zero-sum game solver, and a Simplex solver for real-valued decision variables.

I primarily created this package for educational purposes, and I’m already using it in my operations research, quantitative techniques in business, and computer programming classes.

Today, I submitted a short manuscript to JOSS.

Please ping me if you’re interested in participating as a reviewer for this package in JOSS so I can suggest you when asked.

Have a nice day!

Hi all,

A manuscript of the package has just been published in JOSS with the reviews of @dourouc05 and @odow. I think the package and the paper are far more better than the initial state, thank you all again!

Here is the published paper:

> **[OperationsResearchModels.jl: A Julia package for operations research models](https://joss.theoj.org/papers/10.21105/joss.08592)**
>
> Satman, M. H., (2025). OperationsResearchModels.jl: A Julia package for operations research models. Journal of Open Source Software, 10(113), 8592, https://doi.org/10.21105/joss.08592

I hope it becomes a useful resource for professors who teach operations research courses at universities.

By the way, I’m already using it’s content in my operations research, optimization, and related courses.

Congrats on your package. I remember taking an OPs Research class in graduate school, we solved w/ Excel Solver and some other Excel packages. This looks much nicer!

Excel’s (and LibreOffice’s) solver is perfectly okay but

```julia
solve(problem)

```

is - ofcourse- better 🙂

Thank you!
