Node.js bindings for or-tools vehicle routing problems

node-or-tools

NodeJS bindings for or-tools Travelling Salesman Problem (TSP) and Vehicle Routing Problem (VRP) solvers.

See API.md for documentation.

Solving TSP and VRP problems always starts out with having a m x m cost matrix for all pairwise routes between all locations. We recommend using the Mapbox Directions Matrix service when optimizing travel times.

Quick Start

npm install node_or_tools

var ortools = require('node_or_tools')

var VRP = new ortools.VRP(solverOpts);

VRP.Solve(searchOpts, function (err, solution) {
  // ..
});

See API.md for interface documentation and the example for a small self-contained example.

We ship pre-built native binaries (for Node.js LTS 4 and 6 on Linux and macOS). You will need a compatible C++ stdlib, see below if you encounter issues. Building from source is supported via the --build-from-source flag.

Ubuntu 16.04

You're fine. The system's stdlib is recent enough.

Ubuntu 14.04

apt install software-properties-common
add-apt-repository ppa:ubuntu-toolchain-r/test
apt update
apt install libstdc++-5-dev

Tests

npm test

Building - Undefined Symbols

If your C++ compiler and stdlib are quite recent they will default to a new ABI. Mason packages are still built against an old ABI. If you see undefined symbols errors force the stdlib to use the old ABI by setting:

export CXXFLAGS="-D_GLIBCXX_USE_CXX11_ABI=0"

and re-build the project.

Releases

• Push commit with [publish binary] on master
• Wait for Travis to build and publish binaries, check the AWS bucket if in doubt
• Tag the release git tag vx.y.z -a on master, git push origin vx.y.z
• Then npm login, npm publish to npm
• Make Github Release for tag

node-or-tools's Issues

Allow vehicles to not start at the depot; real-time passenger pick up and drop-off

At the moment all routes start and end at a single depot. Always.
We should allow for vehicles to start already "on the road".

Use-case: real-time passenger pick up and drop-off "ride sharing".

---

Implementation:

Add dummy depot with artificial edges to all start locations. Set edge costs to zero.

Heterogeneous Fleets

Support different types of vehicles such as walk, bike, car.
Could also be used to model "skill sets" when dispatching employees.

This requires the user to hand us vehicle-class specific

• cost matrices
• duration matrices
• capacities

---

Implementation:

For Costs:

Use SetArcCostEvaluatorOfVehicle and provide callback on a per-vehicle basis. We now require numVehicle cost matrices from the user.

For Time Dimension:

Use AddDimensionWithVehicleTransits. Takes a vector of transition time evaluators per vehicle for pairs of nodes. Evaluator(i, j) { return ServiceTime(i) + TransitionTime(i, j); }. We now require numVehicle duration matrices from the user.

For Capacity Dimension:

Use AddDimensionWithVehicleCapacity. See explanation above.

For Time and Capacity:

Use AddDimensionWithVehicleTransitAndCapacity. See explanation above.

demands integer only

While testing the VPR with ~ 500 destinations with demands, some calculated tours are slightly over the given vehicle capacity. The given demands are floats with 2 decimals. Making the vehicle capacity and the demands integers (by multiply by 100), all the tour-demands are just below the vehicle capacity, which is correct.

https://github.com/mapbox/node-or-tools/blob/master/API.md#constructor-1 = Numbers. Floats are numbers, too.

Is this an error in documentation or a bug in the node-or-tools?

How to package google official ortools into static link library

Can you provide a way to package the official ortools into a static link library, I failed to use bazel packaging, thank you

Provide capacities per vehicle at each location in output

We should output the capacity each vehicle has before / after servicing a location.

Use-case: being able to tell the vehicle's load at a specific time and place.

---

Implementation:

• When an assignment could be found: for each vehicle walk over all location indices in the route
• For each location index store the accumulated capacity domain at this location for the vehicle

const auto* loadVar = capacityDimension.CumulVar(index);
assignment->Value(loadVar)

Inconsistent results when giving additional vehicle even if not required

Is it normal to have one result when specifying ONLY 1 vehicle available, and another order result when specifying more than one vehicle?

Error: Cannot find module './binding/node_or_tools.node'

When I try to install the example here: https://github.com/mapbox/node-or-tools/tree/master/example I get error:

 Error: Cannot find module './binding/node_or_tools.node'
     at Function.Module._resolveFilename (module.js:325:15)

although I did:

npm install

and I can see node_or_tools is already installed:

npm WARN package.json [email protected] No repository field.

Pass --update-binary to reinstall or --build-from-source to recompile

any idea?

Optional locations, potentially with penalty

We should expose an option to configure locations as being optional.
Potentially adding a penalty to the solution if the location is not serviced.

---

Implementation: see model.AddDisjunction()

Allow for drivers / vehicles starting at a specific time

We should support drivers starting at a specific time (i.e. not all at the begin of the day).

---

Implementation:

Constrain the min. arrival time at the route's first location:

auto index = model.Start(0);
auto* var = model.CumulVar(index, "Time");
var->SetMin(10am);

Time windows array must include depot?

In your example..

var vrpSolverOpts = {
  numNodes: 3,
  costs: [[0, 10, 10], [10, 0, 10], [10, 10, 0]],
  durations: [[0, 2, 2], [2, 0, 2], [2, 2, 0]],
  timeWindows: [[0, 9], [2, 3], [2, 3]], //<<<< here
  demands: [[0, 0, 0], [1, 1, 1], [1, 1, 1]]
};

timeWindows variable is including a value for the depot index, it must be a full time window? It is represented as hour?

Fairness - balance number of locations serviced per vehicle

We want to be able to balance the number of locations serviced by each vehicle to be as even as possible. The use-case is for example drivers who are getting paid (at least partially) by number of deliveries.

This constraint should be behind a flag and optional.

---

Implementation: use the underlying solver to

• Establish a vehicle vars <-> vehicle counts relationship via the Distribute constraint
• Add a Deviation constraint for vehicle counts targeting the deviation var
• Minimizing the deviation var

Roughly as follows:

std::vector<IntVar*> vehicleCounts;

for (auto vehicle = 0; vehicle < numVehicles; ++vehicle)
  vehicleCounts.push_back(solver->MakeIntVar(0, numNodes));

solver->AddConstraint(solver->MakeDistribute(vehicleVars, vehicleCounts));

auto* deviationVar = solver->MakeIntVar(0, numNodes * numNodes);

solver->AddConstraint(solver->MakeDeviation(vehicleCounts, deviationVar, numNodes));

model.AddVariableMinimizedByFinalizer(deviationVar);

What is durations? And how to declare demands?

i have been able to run your example, also modified it with OSRM to get more than 25 locations.

Did some other examples with more locations and vehicles, and everything works great.

But now i am going to go one step further and test other parameters, but I don't really understand the duration, can you please explain it?
This is what is written in the API docs.

durations Array Duration array the solver uses for time constraints. Two-dimensional with durations[from][to] being a Number representing the duration for servicing node from plus the time for traversing the arc from from to to.

I will try to explain the mean i understand, is it the time that takes to go from pointA to pointB plus the time the driver will stay in pointB

Supposing i will stay 10 minutes in each point

  Distances                   Durations(Travel)         Durations(Travel + Time servicing node)
  |  A -  B -  C |            |  A -  B -  C |          |  A -  B -  C |          
A |  0 - 10 - 20 |          A |  0 - 10 - 30 |        A |  0 - 20 - 40 |          
B | 10 -  0 - 10 |          B | 10 -  0 - 10 |        B | 20 -  0 - 20 |          
C | 20 - 10 -  0 |          C | 30 - 10 -  0 |        C | 40 - 20 -  0 |           

// And this is represented in the array as
distances = [[0,10,20],[10,0,10],[20,10,0]];
// durationTravel =  [[0,10,20],[10,0,10],[20,10,0]]; // without the time servicing node
durationTravelPlusTimeServicing = [[0,20,40],[20,0,20],[40,20,0]];

Also i have another doubt about demand parameter. This is the definition in the readme

demands Array Demands array the solver uses for vehicle capacity constraints. Two-dimensional with demands[from][to] being a Number representing the demand at node from, for example number of packages to deliver to this location. The to node index is unused and reserved for future changes; set demands[at] to a constant array for now. The depot should have a demand of zero.

The instructions says that this has to be a bi-dimentional Array demands[from][to], but only will read the from value, how do you translate this?

// this is in the example
demands = [[0, 0, 0], [1, 1, 1], [1, 1, 1]];

/* if pointA demads 5 and pointB demands 10. How is going to be the array?, 
I know first must be zero because it index to depot. */
demands = [[0,0,0], [5,5,5], [10,10,10]];

Is this correct?

Thank you!

Developer needed

Hi @daniel-j-h , what a wonderful project you've got here! We at letsjobit.com have an app that does order management and planning alongside with route optimisation. Our app is built with Meteor.js (thus, in the nodejs world) but the optimiser is a customized version or o-tools, built in C++.

Our optimisation servers are nodejs services running C++ binaries with child_process basically.

After seeing your project, I'm sure this is the way to go, but we lack the expertise on some of the libraries you're using (like NAN).

Would you be willing to point us in the right direction here or sharing the contact of someone that could assist?

Many thanks and well done!!

How to minimize number of vehicles and enforce routes to maximize usage

Hi,

I'am trying to minimize the number of vehicles while enforcing to maximize their usage. A vehicle can make a route of maximum 7 hours (I calculate "distance" base on time). To do this I use the following lines of code:

However, for what I saw it is apply as a maximum but not as a maximizer. Our idea is that if the algorithm finds 2 routes, then 1 route should be almost 7 hours lenght and the other only the necessary.

Thanks for you time,

Regards,

[HELP] Can't install node-or-tools on Win10, cmd error

Hi,

Something is preventing me from installing node-or-tools and I can't seem to figure out what. I try running it on Windows 10 64bit in Powershell. I tried it both with node v8.10 and v6.13.1 installed. I already solved an issue with the python PATH settings, as well as with C++ VS 15 tools. I have node-gyp and node-pre-gyp installed using npm. I also tried installing without the msvsversion2015 flag.

This seems to be caused by the ignoring of bindings.gyp in the .npmignore. Is this intentional?

Easy installation - publish Node.js bindings to npm

Installation for the user should be as easy as

npm install node-or-tools

We already get our dependencies via mason and have a gyp-based buildsystem.

What's missing is using node-pre-gyp on Travis to build and publish pre-build node-or-tools binaries. Then we can npm publish a package to npm.

Soft time and capacity bounds, potentially with penalty

We should allow for the user to not only add hard bounds (think: time window of 10am--11am, or a specific capacity) but also soft bounds which will add proportionally to the solution's cost if exceeded.

Use-case: think of a hard time window of 10am--1am. Maybe we want to be on time as often as possible. We could set a soft upper bound e.g. of 10:15am adding a penalty proportional to how late we are)

---

Implementation: see RoutingDimension type's Soft member functions adding penalties to the cost.

Expose machine-readable cause of error in callback result

In case of an error in the bindings we use SetErrorMessage in both the TSP and VRP worker to let NAN generate an Js Error for us. What we should add is not only a message but also a parse-able code, think:

{code: 'Timeout', message: 'Unable to find a solution, solver timed out'}

---

Implementation: in the async. workers override

void HandleErrorCallback()

and generate a Js Error object.

NPM install

Hello,
Trying to do an "npm install node_or_tools" on a SunOS 5.11 Linux machine but running into some errors. Have installed globally the "node-pre-gyp" package and "node-gyp" package. Here are the initial build errors...Does the node version have to be 4.8? I have installed Node 6.9.2 and NPM 5.0.3.

Thanks in advance for any help.

The routes result is empty

Hi, @daniel-j-h.
I have tried this library with these params.
numNodes = 7 (except depot)
demands = all 1
numVehicles = 3
and if I use vehicleCapacity >= 5 it will return just 2 routes and another empty route with cost 8778.
If I use vehicleCapacity = 4 it will return 3 routes with cost 9892.
How can I set the results to have full routes?
Thank you for your response.
ps. sry for my Eng, hope you understand.

Building from source fails because src folder doesn't exist

The src folder exists in the repo but not in the npm package (it seems).
It's explicitly ignored in .npmignore, why?

Environment
OSX/Linux (tried both)

Reproducible by
run npm install node_or_tools --build-from-source

Expectation
Building from source succeeds.

Vehicle Specific Cost and Duration Factors

At the moment we expose a single cost and duration matrix per vehicle. What we should allow for in the context of multiple vehicles is cost and duration factors on a per vehicle basis to scale the cost and duration matrix the user passes us, think

numVehicles: 3
costFactors: [1.0, 0.7, 1.5]
durationFactors: [1.0, 0.7, 1.5]

which would scale both the cost as well as the duration matrices depending on the factors for each vehicle. We need to separate cost and duration factors because users could specify e.g. distance as cost in which case costFactors would be [1.0 1.0 1.0] and durationFactors would account for slower and faster vehicles.

Alternative time windows

We need to be able to set multiple possible time windows for each customer (for example, one customer might be available 8-10 and 18-20, but not 10-18).

Node-or-tools only accepts one time window per node though...

I looked at the original OR-Tools docs too, and it seems to be the same there, so not just a limit of node-or-tools: https://developers.google.com/optimization/routing/tsp/vehicle_routing_time_windows

This seems like it would be a pretty common request, especially when you want to optimize schedules/routes for a whole week. I don't think this would add much to the computational complexity btw, as you're just splitting a range into blocks.

Do you have any suggestions? :)

Expose configurable solver knobs

There are a few knobs we can tune and constraints we can set, especially here:

• RoutingSearchParameters
• RoutingModelParameters

We should aim for common use-cases and make the API surface easy to use. At the same time it should be possible to tune your search based on the user's domain knowledge.

Update to or-tools v6.0

Depends on having pre-built binary dependency in mason mapbox/mason#417.

Should be rigorously tested first.

Problem when considering vehicles with different vehicle speed and capacity in Google OR tools python

Hey, can I have an example of how to implement the following in the Google OR with time windows:

1. Different vehicle speeds
2. Different vehicle capacity
3. Delivering packages rather than picking it up

I know I have to use AddDimensionWithVehicleTransits but I dont know how to use it.

Not giving the best (shortest and fastest) route

It is not taking the best (shortest and fastest) route. The image shows the points to visit ordered as the VRP result.
i use node-osrm to get the cost table using.

As you can see, it ordered to visit A > C > B > D

I Draw these points to osrm route and give this as not the fastest one.

The fastest one was ordering as A > B > C > D , just by some little difference, but i expect it to be the optimized order

RouteLocks is for establish starting points in order, or to assign points to route to visit optimized?

I am working with routeLocks to assign some points to a certain route and to visit them along with others remain, in a optimized way. But instead it just makes the VRP to push them in first place to visit starting the route without analyze if those points are optimized.

As you can see in the image red route start from point depot, goes to point 1, next it goes back to point 2, and goes to point 3 which is close to point 1. With routeLock I expected to assign those points to certain route and visit them optimized. As you can see the route is not optimized, it goes far away, and then comes close to depot, then goes far away close to the first point and come back to depot, the traveling time is the highest possible.

Expected result..

Or this..

Any help?
Did I understand wrong?
Is Node-or-tools capable to solve this and assign points to a route and visit them in a optimized way?

Minimizing Makespan - the total duration vehicles are on the road

At the moment users can pass in a durations matrix for costs and we will minimize the total number of vehicle driving hours. In contrast, this ticket is about minimizing the total duration vehicles are on the road.

---

Implementation:

Minimize the route's end cumul var. for the time dimension. This will minimize the overall completion time.

for (auto vehicle = 0; vehicle < model.vehicles(); ++vehicle)
  model.AddVariableMinimizedByFinalizer(model.CumulVar(model.End(vehicle), timeDimension));

Handling large numbers (400) of locations?

We have around 400 missions/locations. From what I understand, that means we need to start with 400x400 distance matrix. Both yours and Google's Distance Matrix APIs have a maximum of 25x25.
Is it expected that I make many (about 256) requests, and then merge the matrixes myself?
And if the Distance Matrix API can only handle 25x25, is OR-Tools even built to handle this many locations? Or am I supposed to do some sort of pre-culling before creating the matrix?

Vehicle Specific Capacities

At the moment we expose a single vehicleCapacity property. With it users can set the capacities for all their vehicles. What we should do instead is expose a vehicleCapacities property (parallel array coinciding with the vehicles) where the user can specify a capacity on a per vehicle basis.

Multiple time windows per location

We should expose the possibility to specify multiple time windows per location.

Use-case: you can service a location between 9am--11am and between 1pm--3pm.

---

Implementation:

• Sort intervals per location by start then stop, assert for non-overlapping
• Take the min and max and set CumulVar(n)->SetRange(minStart, maxStop)
• Walk over adjacent intervals and remove in between CumulVar(n)->RemoveInterval(stop, start).

Build Debug Bindings for NPM

In #23 we switched to statically linking against upstream libortools.a and more importantly strip out debug symbols here. What we should do is build debug binaries for npm which link against libortools.a with debug symbols not stripped out.

Tasks:

• Create Travis builds for debug binaries which do not strip out debug symbols
• Publish debug binaries passing --debug to node-pre-gyp
• Make a new release https://github.com/mapbox/node-or-tools#releases
• Check s3 to see if debug binaries are there

Size too large for deployment. Possibilities to reduce size?

Hey, guys. Thanks for making a great library. I'm getting beautifully optimized routes!

My issue revolves around the resulting library size. Pulling from npm, this library comes in at a chunk of 475 MB, and it looks like the biggest piece is libtools.a @ 317 MB.

Is there any way I can reduce this size? We were really hoping to use this in a Lambda function to build optimal routes for our fleet, but the Lambda max is 250 MB. Is there another version of libtools.a or node-or-tools in general that's a bit slimmer?

Thanks a lot for any help!

Edit: Using --build-from-source doesn't work either if it helps.

Update to more recent or-tools library

Looks like v6.7.1 of or-tools has been released. We're currently only linking against 6.0 (from May, 2017). We should update, and see if there are new knobs we can expose.

how to minimize each vehicle time in vrp with or-tools

i want minimize network time in other words: each vehicle time should be minimized as possible
1- this means force all vehicle to service locations
2- and balance number of locations serviced per vehicle
3- and minimizes the time the last vehicle will arrive to its end node
@daniel-j-h what you said about forcing all vehicle works fine but others not working at all
do you have any idea to do number 3?

Option to force all vehicles to service locations

We should provide an option to force all vehicles on the road.
Probably goes hand in hand with the fairness constraint, see #1.

---

Implementation: remove the depot from the start's NextVar, so vehicles have to service locations:

model.CloseModel()

for (auto vehicle = 0; vehicle < numVehicles; ++vehicle) {
  IntVar* const start = routing.NextVar(routing.Start(vehicle));
  for (auto node = routing.Size(); node < routing.Size() + routing.vehicles(); ++node)
    start->RemoveValue(node);
}

any plan for supporting recent node version ?

What is depotIndex?

As I am reviewing the source code of node example, I did not understand the depotIndex, can you please explain it?

Also, how to define origin point? considering locations are all destinations?

Last question please, in the example, there is:

  // 9am -- 5pm
  var dayStarts = 0;
  var dayEnds = 8 * 60 * 60;

how did you figure out the 9am ? as dayStarts equals to zero?

Thank you!

Problem when providing pair of pickup and delivery indices

Hey,

There is this issue where providing a pair of pickup and delivery indices would lead to this error message: Unable to find a solution

Expected Behavior

It should return a valid route order based on cost array.

Current Behavior

Returns Unable to find a solution

Steps to Reproduce

1. Copy node-or-tools/test/vrp.js file content to a new file
2. Remove all assertions
3. Add a pair of pickup and delivery indices in searchOpts.

   pickups: [4, 7],
   deliveries: [7, 10]

Context (Environment)

I have a pair of pickup and delivery indices and I want to visit one or more stops before visiting others.

This is my code snippet. You could see that if we remove the pickup and delivery indices, the code will work but after adding aforementioned indices, it returns Unable to find a solution

module.exports = () => {
  const ortools = require('node_or_tools')
  var locations = [
    [0, 0], [0, 1], [0, 2], [0, 3],
    [1, 0], [1, 1], [1, 2], [1, 3],
    [2, 0], [2, 1], [2, 2], [2, 3],
    [3, 0], [3, 1], [3, 2], [3, 3]]

  var depot = 0

  function manhattanDistance(lhs, rhs) {
    return Math.abs(lhs[0] - rhs[0]) + Math.abs(lhs[1] - rhs[1])
  }

  var costMatrix = new Array(locations.length)

  for (var from = 0; from < locations.length; ++from) {
    costMatrix[from] = new Array(locations.length)

    for (var to = 0; to < locations.length; ++to) {
      costMatrix[from][to] = manhattanDistance(locations[from], locations[to])
    }
  }

  var dayStarts = Hours(0)
  var dayEnds = Hours(3)


  var seed = 2147483650

  function ParkMillerRNG(seed) {
    var modulus = 2147483647
    var multiplier = 48271
    var increment = 0
    var state = seed

    return function() {
      state = (multiplier * state + increment) % modulus
      return state / modulus
    }
  }

  var rand = ParkMillerRNG(seed)


  function Seconds(v) {
    return v
  }

  function Minutes(v) {
    return Seconds(v * 60)
  }

  function Hours(v) {

MbxClient.getMatrix is not a function

I've tried to run the example, however, I got this error:

/home/ubuntu/ortools/node-or-tools-master/example/index.js:78
MbxClient.getMatrix(locations.map(function (coord) { return { longitude: coord[0], latitude: coord[1] } }), {profile: profile}, function(err, results) {
          ^

TypeError: MbxClient.getMatrix is not a function

I am sure that MbxClient is initialized, and I can see it in debugger as attached snapshot:
