The web platform DecSpace is a Decision Support System (DSS) that is offered as a web-based service available in most browsers. It aims to have a user-friendly interface, providing a simple and straightforward way to create, modify and share multiple projects in the form of workflows. This platform can also be used for teaching purposes in the future.
The Distance Matrix App is an application with the objective of calculating the matrix of real distances (by road) between a set of points characterized by their geographical coordinates. The code was written in Python 3.6 using a service provided by openrouteservice, using the API made available for this purpose.
Route Plotting is an application developed to facilitate the visualization of the routes present in a solution of mathematical models implemented with the GAMS software. The code was written in Python 3.6. The application writes the sequence of visits in excel, and represents the routes using the openrouteservice.org service, using the API made available for this purpose.
MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique) is an interactive approach that requires only qualitative judgements about differences to help a decision maker or a decision-advising group quantify the relative attractiveness of options. It employs an initial, interactive, questioning procedure that compares two elements at a time, requesting only a qualitative preference judgement.
As judgements are entered into the software, it automatically verifies their consistency. A numerical scale is generated that is entirely consistent with all the decision maker ‘s judgements. Through a similar process weights are generated for criteria.
