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...

PiM Mini Model on Associated Costs by Kai Neumann

This mini model shows one of two ways to calculate costs within PROCESS-iMODELER models. Costs can be either as shown here the directly associated costs or like shown in another model the costs of the availability of the resources. For the associated costs you simply connect the process factors to a normal factor and use the costs() function times the process. The costs() value of each process step is the sum of the costs (a parameter of the resource- and level-resource factors) that are connected with t...

Are investments into green energy macroeconomically costs? by Kai Neumann

This qualitative model and its description in the presenter shows an interconnected view of the advantages and disadvanteges of today's investments into green energy.

For Paris: Why actions against climate change do not cost jobs by Kai Neumann

This model was meant to be a small model on the basic interconnections of actions against climate change and the main counter argument against them that they allegedly cost jobs. Feel free to add to it.

Are Resource Costs Macroeconomically seen Costs? by Kai Neumann

In many of my client's models and I have to admit in some of my own as well the depletion of resources simply leads to an increase of resource prices which decreases spending power and competitiveness. But if we widen our system's boundary we can at least put into perspective this view. This qualitative model shows why.

Open Source Horizon Scanning Trend Forecast Foresight Model (1) by Kai Neumann

This model should help to collect news from all over the world and put them into cause and effect relation to each other, and to the factors that define the economy, the societies, the environment, and everyone. Those factors we call targets, colored yellow. Whenever some interesting news pops up we may add further target factors to connect them with the central target of our all well being. The model should remain as general as possible. A small manual is provided with the Menu ... Presenter. News could...

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...

Bringing an E-Car to market (ToC example model) by Kai Neumann

This is just a small example model for part 3 of a series of guidances called "Quantitative Optimization and Risk Analysis of Projects and Processes". It describes a fictitious case of a start up enterprise that develops and produces a new electric vehicle. Here is the link to the guidance: http://www.consideo.de/downloads/Culture_of_Reflection_p3.pdf Here is the Operations Research version using the iM Optimizer: http://www.imodeler.info/ro?key=Cv-vW-0iM4jA9XyEX5IUQcw Here is the Monte Carlo version sim...

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 :-)

Power2Gas by Greenpeace Energy by Kai Neumann

I was interested to change to a power to gas subscription from greenpeace energy in which they offer to invest into power to gas (wind and solar energy is electrolytically transformed into methane that can be transported with the existing fossile gas network) yet to be built. I disliked that right now there is only a minor proportion of power to gas included in their regular fossil gas supply and that there are too few investors. I argued that they should offer a high priced but consequent product which ...
