In this post, I describe how deeply uncertain parametric data can be controlled in an optimization model to gain conservative solutions and decisions. The investigated robust optimization approach can lead to least, partially, or fully conservative solutions by paying the […]
One of the duties I frequently performed as an operations research analyst in consulting projects was optimizing companies’ supply chain network designs. A supply chain is a network that connects suppliers with customers to procure materials, transform them into final […]
This post is the first post in an upcoming series of posts on AnyLogic simulation modelling. I want to introduce basic material handling system simulation modelling using AnyLogic as a discrete-event simulation machine and modelling environment. I will use AnyLogic’s […]
Providing a coding example for how to conduct spatial proximity customer clustering, applicable e.g. when searching for multiple centers of gravity (i.e. when wanting to locate multiple warehouses). The logic and approach is the same as in any kind of distance based […]
In a previous post on SQLite 3 and Python I added two related tables to a SQLite 3 database, usign Pyhton. The tables are called universitiesTBxx and studentsTBxx. Both tables are stored in a database called “newDatabase.db”. Students are enlisted […]
In a previous post I already demonstarted how one can connect to a SQLite 3 database in Python and how one can create tables in the connected database. I also demonstrate how one can write data into a table created […]
In this post I will demonstrate how you can create SQL databases powered by SQLite as a database engine in Python. I will be using the sqlite3 engine. The SQLite driver is installed by default through the Python installation itself. […]
In Python it is possible to index dictionaries with tuples. I made use of this technique in one of my previous posts, covering constraint programming with Google OR-tools in Python. I demonstrate the technique in the coding example below: # […]
In previous posts I have already introduced Google OR tools for linear programming. In this post I want to demonstrate the capabilities of Google OR tools for constraint programming. More specifically, I will solve a job scheduling problem using constraint […]
I previous posts I have already introduced seaborn and matplotlib.pyplot for visualization in Python. In this post I want to introduce the altair module. This is an alternative module supporting visualization in Python. The altair module can be installed with […]
In this post I want to introduce a module available in Python for automatizing the creation of drawings in AutoCAD. The module is called pyautocad. It is supported by pip install for easy installation. The pyautocad module will also allow […]
In this post I will demonstrate the layer walk tool in AutoCAD. In other posts I have introduced basic AutoCAD commands such as AutoCAD LINE, AutoCAD PLINE etc. I have also demonstrated how one can use pyautocad for scripting AutoCAD […]
In this post I will demonstrate the AutoCAD MLINE command for drawing multilines in AutoCAD. I start by entering the MLINE command into AutoCAD. AutoCAD will prompt me for a start point. After having selected the start point AutoCAD will […]
In this post I will demonstrate the AutoCAD XLINE command. In other posts I already demonstrated simple AutoCAD commands such as e.g. AutoCAD LINE, AutoCAD MLINE, AutoCAD CIRCLE, AutoCAD OFFSET and many more. You can create construction lines of infinite […]
In this post I will demonstrate rays in AutoCAD, using the AutoCAD RAY command. In other posts I already demonstrated other simple AutoCAD commands, such as e.g. the AutoCAD PLINE command. Rays or ray lines are linear objects that have […]
