A dynamic analysis for the behavior of traffic accidents of motorcyclists is proposed based on a case study about Avenida Boyacá, in Bogotá, D.C. The proposed model includes three main agents which generate traffic accidents: motorcyclists, road infrastructure and psychological and physical causes. Three causal loops are identified with these agent...

Questions (7)
Question
Assume a cancer patient that has just received a specific procedure A. Is it possible to know the probability to be referred to a following procedure B? Like in a network of procedures?
I have found some characterization studies for specific cancer populations of patients, but I'm looking for a more quantitative and modelling approach.
Question
Python provides access to powerful tools for solving LP/MILP optimization problems. Gurobi, PulP and Pyomo are some of them. I would be pleased to get your opinion about its pros and cons. How would you describe them in terms of usefulness, pythonic coding, flexibility, efficiency and efficacy?
By the way, I'm sharing this post from Mohsen Moarefdoost which can bring an inside to this topic.
Thanks a lot in advance.
Question
I am working on a research to assess healthcare systems performance in terms of the flow of orders through networks. Therefore I'm looking for quantitative indicators for the following characteristics:
  • Accesibility: probability to receive attention
  • Continuity: probability to receive different services through once the patient has been received in a healthcare network.
  • Opportunity: how hard does it its to receive attention in a rational term?
  • Integrality: capability of healthcare systems to bring a complete package of different services for patients depending on their diagnosis
  • Resolutivity: posibility to effectively satisfy patient's needs for health services.
Thanks in advance.
Question
System Dynamics modelling some times require the flexibility of programming and available simulation software simply doesn't brings that flexibility. I am looking for examples of the use of Python as a software to develop System Dynamics models. I will try to use them in the modelling of healthcare systems based on big data.
Question
We are looking for a methodology or framework that may allow us the characterization of a network composed by more than 20 hospitals in a region of Colombia. Our characterization is related with the logistics infrastructure, processes and performance measurements of the network and its components.
Question
We are trying to introduce Logframe as a tool that facilitates the project development for undergraduate industrial engineering students. Therefore, we would like to know different experiencies from researches about the use of this tool in such environments.
Thanks a lot in advance.
