Vehicle routing benchmark instances

For a table of benchmark instances on SDVRP you can have a look at Table 4 (Benchmark on known SDVRP problem instances) of Ray et al. (2014)1. More details are provided in reference [30]2 of the paper....

Real world demand dataset

Time Series Data Library The time series data library from Rob Hyndman has hundreds (~648+) of time-series data. It depends on what you call "demand" and what you require as a "sufficiently long ...

How would you characterize "optimization data?"

I would just call it "planning data". I think it might be easier to convince an administrator that "planning data" needs to be recorded/captured than to sell them on "<...

How would you characterize "optimization data?"

I would call them decision-relevant data, because most optimization problems in practice help people do decisions better, which they already do in a heuristic fashion. This puts the focus on the ...

Tool/Editor to visualize optimization problem files and solutions

AFAIK, some software such as GAMS, Lingo, AMPL and SCIP have had facilities to deal with it. For example, GAMS has a list file which contains much useful information about the problem and its solution....

How would you characterize "optimization data?"

Adhering to the rules of encapsulation, I would simply call it "parameters". If we're thinking of an optimisation model and, as you said, what changes is the number of things (number of ...

Tool/Editor to visualize optimization problem files and solutions

This might be not exactly what you are looking for but GCG (based on SCIP) has a nice visualize command that you can call after it found a decomposition (Dantzig-...

Decoding a Deep Neural Network as an Analytical Expression for Optimization Purpose

It is possible. Although I haven't done this for a deep neural network (my experience was on a multi-layer perceptron), it shouldn't be that different procedure-wise. Considering that each neuron ...

Strategic planning based on average values

The following may or may not be useful for hub location problems, but is certainly applicable to many problems pertaining to the title "Strategic planning based on average values" If $X$ is a random ...

Strategic planning based on average values

I come across the problem quite a bit (am a practitioner in a utility company building offshore wind farms), and here is my take: As Marco said, try to get as much data about the system as possible: ...

Decoding a Deep Neural Network as an Analytical Expression for Optimization Purpose

Instead of deep learning, you can try to use so-called "explainable machine learning", where you learn directly Boolean rules which are generally restricted to be short (of course, accuracy may suffer ...

Vehicle routing benchmark instances

The usual way to check which instances are still open is to check the latest paper(s) on exact solution of the problem. The latest papers seem to be https://pubsonline.informs.org/doi/abs/10.1287/trsc....

Tool/Editor to visualize optimization problem files and solutions

What you are asking for sounds somewhat similar to Alteryx (which starts at $5,195/user per year). Let's see how we can duplicate some of the look and functionality that with free tools. A demo video "...
