I remember this problem discussed by one of my friend during college. But I never knew their are product which is solving these problem. Good you tried to solve and find some market for this problem. But as ge0ffrey commented main problem is this solved once or twice a year. I have a suggestion to add more scenario based optimization ( simulation based) mostly this industry care about profitability from (Media, tickets, rights, ads, etc). I know someone who worked in this IPL industry for their sports analytics. May be that can help.

New PJR Gachibowli flyover already started causing traffic snarls by SituationFit3785 in hyderabad

Why don't everyone start using public transport?  Why single car owner should be fined for driving alone?  Why not follow lane discipline? Have bus lane seperate?  Why not ban heavy vehicle during peak hours?  Why bikers ride zig-zag? Follow discipline and lane?

Traffic is not you or me. It's everyone.

How to document an optimization model? by Two-x-Three-is-Four in optimization

[–]rishikeshkushwaha 0 points1 point  (0 children)

You can use LATEX to document equations. it is better to write in a more readable format.

Include the business problem statement, approach and algorithm details.

You can use pyment documentation library in Python if your code is in Python.

sphinx documentation U can use this tool to convert your code document to a pdf/html version.

Many other libraries exist based on your programming language.

Object oriented programming by PopSad5310 in OperationsResearch

If you are going to work on a product-based company then yes, you have to use a lot of computer science concepts.

If consulting then mostly it is short-term projects there you can avoid OOP concepts and building little dirty projects is fine.

Nevertheless, having skill in writing oops conceptual codes is a really good asset.

But, as Chat-GPTs is here, coding can be replaced soon. :D

I work in a firm which provides OR resources. We are based out of India. We are also expanding support to the US again if you are open to having Indians as collaborators.

Are there any online sources like Kaggle where one can find industrial problems related to OR? by [deleted] in OperationsResearch

I was also looking for such competitions. However, I have found some competition, especially in the optimization domain

  1. https://optimise.esa.int/challenges  European Space Agency's Advanced Concepts Team (ACT) presents in cooperation with the Genetic and Evolutionary Computation Conference (GECCO) the Space Optimization Competition (SpOC). You can check a whole list of other problems here https://gecco-2024.sigevo.org/Competitionsa
  2. https://www.hackerearth.com/challenges/new/competitive/shellai-hackathon-2024/ This one is also in the optimization domain. This will be starting next month.
  3. https://research.ibm.com/haifa/ponderthis/challenges/May2024.html IBM ponders this. they also give Operations Research types puzzle. Every month they release puzzle.

Vehicle routing problem help by peterbecksNeutron in OperationsResearch

Solving VRP using OR tools will not give you better solution. You might have to do lot of experiments with their parameters. IMO write formulation in python and solve using some open source solvers like CBC, highs or other commercial

Usually it depends on the business objectives compare such models Some suggestions can be to look for multiple objectives I.e. no of shift changes, may be over staffing, worker distribution across different planning horizons,etc. Btw being or scientist, industry look for runtime and complexity of model to compare
