Truck haulage simulation animation in Python

truck haul simulation animation in Python

In this article I will share a discrete-event simulation animation example in Python. More specifically a truck haul transport simulation animation for a mine, using SimPy and DesViz in Python. This example, and the DesViz module, was developed by Prof. Paul Corry and his team and I am resharing his example in this post. Using DesViz SimPy model developers can animate their simulation model .

Below is an animation of a SimPy truck haul simulation model for mining operations.

The example is documented and available in Paul Corry’s GitHub repository: https://github.com/corryp/DesViz

How can DesViz be used for simulation animation in Python?

Citing directly from the DesViz documentation:

DesViz is a collection of Python classes and functions facilitating asynchronous animation for discrete event simulation ( DES ) models. It is built on top of the Pyglet package which provides the underlying graphics functionality. DesViz allows a DES model to write a csv file which is later interpreted by DesViz to configure and move sprites representing background and foreground objects in the simulation. Each line of the csv file gives the simulation time, an animation instruction and set of arguments relating to that instruction. These instructions provide a compact method to specify sprite appearance and movements in ways that are useful in a DES context. DesViz documentation, by Paul Corry

SimPy developers can use DesViz to animate their simulation model , in a two-step approach. First, they must use the DesViz library to generate and store animation data. Next, the animation is used for rendering an animation.

Here are some examples of what you can animate with DesViz:

  • movements from pixel point to pixel point or along predefined paths, with automatic object orientations
  • adjusting object orientations, i.e. animate object rotations
  • define master-slave relationships between objects for animation purposes, e.g. truck (master) and trailer (slave)
  • progress bars, either static or attached to another object (i.e. moving together with the associated object)
  • labeling, annotation, and background images
  • defined animation speed (frame interval, i.e. fps – frames per second)

Under the hood, DesViz populates a database (csv-file) with defined animation instructions. These instructions must be implemented into the simulation application itself. The underlying database is populated during simulation execution and is then used for rendering the animation itself. For this, DesViz provides are range of classes, methods, and functions.

Creating a Four-step Transportation Model in Python

A four-step transportation model predicts the traffic load on a network given data about a region. These models are used to evaluate the impacts of land-use and transportation projects. In this example, we will create a model representing California as if it acted as a city. To get started, first we will import the necessary libraries. All of these can be installed from pip.

Step 0 Gather Data

First we need some data about the study area. Supply data is the transportation network including roads, public transportation schedules, etc. To keep things simple, we are going to assume the transport network is a line connecting the centroid of each zone to the centroid of each other zone.

Supply Data

At this point we can plot our zones and see how they look:

Zones

Demand Data

Demand dats is the users of the transportation network. For passenger models, demand data is typically census data including residential locations, work locations, school location, etc. For freight models, demand data could be tons of freight, number of bananas, etc. In this case we will study workers' home locations (from the 2015 American Community Survey (ACS) 5-Year Data) and employees' locations (from the Bureau of Labor Statistics (BLS)). (The BLS API seems to be quite slow...)

The second to last line makes sure the sums of Production and Attraction are equal. Iterative Proportional Fitting in Trip Distribution will fail if they are not. We assume people with multiple jobs are spread thoughout the study area. Now let's take a look at where our commuters live and work:

We can easily see that Alameda and Alpine Counties see an influx of commuters during the day and Butte and Calaveras Counties are the opposite.

Step 1 Trip Generation

Trip Generation is where we compute the numbers for Production and Attraction. We completed this above.

Step 2 Trip Distribution

In Trip Distribution we use a Gravity Model to calculate a cost matrix representing the cost of travel between each pair of zones. First, we create a simple cost function. Then we use that function to calculate our cost matrix by interating through all possible zone pairs. Then we can use our cost matrix to distribute our trips across our study area. Changing the beta parameter adjusts the Friction of Distance . Beta will vary based on the units of distance. We use a Haversine Function to calculate distances in kilometers (or miles) from geographic coordinates. The Trip Distribution function uses Iterative Proportional Fitting to assign trips from our Production and Attraction arrays to our matrix.

If we take a look at the trips table we can see that most trips stay inside each county, but some go quite far. Origin zones are on the left. Destination zones are on the top.

Step 3 Mode Choice

At this point we have a matrix of the number of trips from each zone to each zone. Next we split those trips across the available modes, in this case walking, cycling, and driving. For this we create a Utility Function that describes the utility gained from the trip minus the utility lost due to travel time, cost, and other negative factors associated with the mode. We then use this utility function to determine the probability of taking each mode for each zone pair. Similar to Trip Distribution, we use these probabilities to compute a matrix. We can then multiply our trip matrix by the probability matrices to get the number of trips between each zone pair using a given mode.

Now we can look at the number of driving trips between each zone pair.

Step 4 Route Assignment

At this point we have a matrix of all trips from each zone to each zone by mode. We could use this information to calculate mode share percentages. However, we would also like to see how the trips look on the transportation network. For that, we create a graph to represent the network. Then we calculate the shortest path for each trip and add all the trips to the network ignoring capacity contraints. Last, we can visualize our trips and see how the traffic is distributed. The width of the line between centroids show the volume of traffic.

Here are our trips:

Zones

Obviously the scale of this example is quite ridiculous. Because the cost of travel is so low, our model is telling us that there will be many long distance trips. And because we used centroid-to-centroid routes, there is no concept of geography. This makes the route through the east of the state the fastest path north to south. However, this is the simple method used by transportation planners around the world to predict travel patterns. If you'd like to play with the parameters, here are all the functions:

That's all folks. Questions? Improvements?

Solving Transportation Problem using Linear Programming in Python

Learn how to use Python PuLP to solve transportation problems using Linear Programming.

In this tutorial, we will broaden the horizon of linear programming problems. We will discuss the Transportation problem. It offers various applications involving the optimal transportation of goods. The transportation model is basically a minimization model.

The transportation problem is a type of Linear Programming problem. In this type of problem, the main objective is to transport goods from source warehouses to various destination locations at minimum cost. In order to solve such problems, we should have demand quantities, supply quantities, and the cost of shipping from source and destination. There are m sources or origin and n destinations, each represented by a node. The edges represent the routes linking the sources and the destinations.

truck python assignment expert

In this tutorial, we are going to cover the following topics:

Transportation Problem

The transportation models deal with a special type of linear programming problem in which the objective is to minimize the cost. Here, we have a homogeneous commodity that needs to be transferred from various origins or factories to different destinations or warehouses.

Types of Transportation problems

  • Balanced Transportation Problem :  In such type of problem, total supplies and demands are equal.
  • Unbalanced Transportation Problem : In such type of problem, total supplies and demands are not equal.

Methods for Solving Transportation Problem:

  • NorthWest Corner Method
  • Least Cost Method
  • Vogel’s Approximation Method (VAM)

Let’s see one example below. A company contacted the three warehouses to provide the raw material for their 3 projects.

truck python assignment expert

This constitutes the information needed to solve the problem. The next step is to organize the information into a solvable transportation problem.

Formulate Problem

Let’s first formulate the problem. first, we define the warehouse and its supplies, the project and its demands, and the cost matrix.

Initialize LP Model

In this step, we will import all the classes and functions of pulp module and create a Minimization LP problem using LpProblem class.

Define Decision Variable

In this step, we will define the decision variables. In our problem, we have various Route variables. Let’s create them using  LpVariable.dicts()  class.  LpVariable.dicts()  used with Python’s list comprehension.  LpVariable.dicts()  will take the following four values:

  • First, prefix name of what this variable represents.
  • Second is the list of all the variables.
  • Third is the lower bound on this variable.
  • Fourth variable is the upper bound.
  • Fourth is essentially the type of data (discrete or continuous). The options for the fourth parameter are  LpContinuous  or  LpInteger .

Let’s first create a list route for the route between warehouse and project site and create the decision variables using LpVariable.dicts() the method.

Define Objective Function

In this step, we will define the minimum objective function by adding it to the LpProblem  object. lpSum(vector)is used here to define multiple linear expressions. It also used list comprehension to add multiple variables.

In this code, we have summed up the two variables(full-time and part-time) list values in an additive fashion.

Define the Constraints

Here, we are adding two types of constraints: supply maximum constraints and demand minimum constraints. We have added the 4 constraints defined in the problem by adding them to the LpProblem  object.

Solve Model

In this step, we will solve the LP problem by calling solve() method. We can print the final value by using the following for loop.

From the above results, we can infer that Warehouse-A supplies the 300 units to Project -2. Warehouse-B supplies 150, 150, and 300 to respective project sites. And finally, Warehouse-C supplies 600 units to Project-3.

In this article, we have learned about Transportation problems, Problem Formulation, and implementation using the python PuLp library. We have solved the transportation problem using a Linear programming problem in Python. Of course, this is just a simple case study, we can add more constraints to it and make it more complicated. In upcoming articles, we will write more on different optimization problems such as transshipment problem, assignment problem, balanced diet problem. You can revise the basics of mathematical concepts in  this article  and learn about Linear Programming  in this article .
