The world economy - modeling an article from the SPIEGEL by Kai Neumann

Here is a small model of the arguments taken from an online article from the SPIEGEL: http://www.spiegel.de/wirtschaft/wachstum-der-weltwirtschaft-der-kapitalismus-ist-kaputt-a-1028098.h...

PiM: Demo model for modeling supply chains and optimal inventories 2 by Kai Neumann

This is a small example model that shows how to use normal factors and delays to model delivery times (so you do not always have to use PiM factors); how to identify the optimal quantity of orders and how to identify the optimal number of resources. Do not hesitate to ask for more explanations or some variations of the model :-)

Oil System Model by pierreweidemann@w*

The "Oil System Model" tries to show the significant influences on the price of oil and their implications. Originally created by Gene Bellinger Feel free to join in on the modeling by clicking the collaborative link. Source  - -http://www.systemswiki.org/index.php?title=Oil_System_Model

Quantitative model on smallholder's income (Workshop example using Monte Carlo) by Kai Neumann

This quantitative model is from a workshop for the University of Cape Coast. It features a small quantitative model that starts with a steady constant development of a smallholder's income from growing one crop. Via step by step simulation it can be changed. The model, then, was enriched by a Monte-Carlo simulation of the possible influence from extreme weather and by the use of the range() function to look for all possible combinations to identify an optimal solution. Note: some of the factors have an e...

Interpretation of loops: a dispute between qualitative and quantitative modelers by Kai Neumann

Small model to show the limits and strengths of qualitative models when we look at loops.

PiM Mini Model on Costs based on Availability by Kai Neumann

This mini model shows one of two ways to calculate costs within PROCESS-iMODELER models. Costs can be either as shown in another model the directly associated costs or like shown here the costs of the availability of the resources. For the availability of resources you simply sum up the cost of a resource times the number of principally available resources. The use of level resources can either be equally their principal availability or their use. For this you can use the possibility to connect a process...

Example model on Value Chains (Quantitative Process Model) by Kai Neumann

Just a small example model to show the benefits of quantitative modeling of value chains (https://en.m.wikipedia.org/wiki/Value_chain) The model shows just the basic use of process and project factors as well as resource factors and parameter for their prices. The major benefit of the iMODELER is now to continue with non-linear dynamics in case of reinforcing errors or variations analysed with Monte Carlo simulations to match reality‘s complexity. Don‘t hesitate to ask for more specific and advanced exam...

PiM demo model on IT processes p2: developing solutions by Kai Neumann

This small PiM model shows how an IT company that develops apps or designs websites or installes software can be modeled in order to identify bottlenecks or constraints and to simulate the costs and income (benefit management)

Refugees from different regions - a collaborative model by Kai Neumann

The aim of this model is to have a closer look at the root causes for the flow of refugees from specific countries and regions. Please add your arguments.

qualitative mini model on sustainability by Kai Neumann

Just a small but powerful model to show the features of different qualitative weightings between short, medium and long term.
