Purpose: Employ the Mono Lake model adapted from "Modeling the Environment" by Andrew Ford as a basis for developing a set of guidelines to support asynchronous multi-user model development.
Mono Lake is an ancient inland sea on the eastern side of the Sierra Nevada. From a policy point of view Mono Lake is the story of how a handful of people began a campaign to save a dying lake
Because our problem solving approaches in today's reality don't produce very good solutions we end up continually dealing with unintended consequences which make the original problem worse or create new problems to be dealt with.
Use a bathtub model to investigate the manner in which inflows and outflows govern the quantity of a stock. Extend the structure to create and investigate the relationships of a goal seeking balancing loop.
The situation Big Box Distribution considers to be a problem is an average accounts receivable period which is considered unacceptable as it is costing them money.
This is a definition of the Systems Thinking Interactive Learning Environment (STILE) development process which was used to create Beyond Connecting the Dots (BCtD).
The issue of increasing private and government debt to banks is a major
concern after the financial crisis of 2008 (see Figure at link given below). In order to
understand why our society and government is increasingly indebted to banks we
need to understand how our current money system works and why we need a
continuous infusion of new money in a growing economy. “Why We Are Increasingly
Indebted To Banks?” investigates the reasons behind this and suggest a possible
solution.
The simple savings account is used to demonstrate the nature of a reinforcing loop. Change the initial amount and interest rate and run the model to see the implications of changing these values.
While understanding the interacting components responsible for the situation is important it is even more important to understand the stakeholders as they are the ones responsible for the interacting components being the way they are.
You've probably heard the comment "It's the economy stupid!" Well I've finally concluded that when it comes to the economy "It's stupidity stupid!" might be a more appropriate phrase.
The Sensitivity Analysis option allows you to develop a sense of the extent to which some part of the model is affected by changes in some other part of the model. I think you'll find the approach to implementing Sensitivity Analysis rather straightforward and powerful at the same time.
Use a savings account model to investigate the manner in which inflows and outflows govern the quantity of a stock. Extend the structure to create and investigate the relationships of a growth producing reinforcing loop.
Now that we have some context for the situation it's appropriate to begin to investigate, though possibly not where you might think. And the investigation is actually a bit hindered because management fired the accounts receivables department. What I'm really interested in is trends as to how things have evolved over time.
