Overview
A model which simulates the competition between logging versus adventure tourism (mountain bike ridding) in Derby Tasmania. Simulation borrowed from the Easter Island simulation.
How the model works.
Trees grow, we cut them down because of demand for Timber amd sell the logs.
With mountain bkie visits. This depends on past experience and recommendations. Past experience and recommendations depends on Scenery number of trees compared to visitor and Adventure number of trees and users. Park capacity limits the number of users.
Interesting insightsIt seems that high logging does not deter mountain biking. By reducing park capacity, visitor experience and numbers are improved. A major problem is that any success with the mountain bike park leads to an explosion in visitor numbers. Also a high price of timber is needed to balance popularity of the park. It seems also that only a narrow corridor is needed for mountain biking

This is a simulation of monetary flows for a business that uses
Circular Money.
All numbers represent 1000's of dollars. So a revenue of 3 means a revenue of $3000.
Revenues and expenses are monthly.

uses a deceptive narrative to declare that money the government spends into the economy in excesses of the taxes it collects creates a ‘government debt’.
In fact, the money the government spends into the economy in excess of the
taxes is an income, a benefit for the private sector. When the government
issues bonds, the money the private sector uses to buy them via banks comes
from a residual cushion of dollars that the government already spent into the
economy but has not yet taxed back. If
this were not the case, if the government had taxed back all the money it spent
into the economy, then the economy could not function. There would be no
dollars in the economy, since the government is the sole supplier of U.S.
dollars! In the doted rectangle in the graph you can see that the dollars paid to
the government for bonds sits in a dollar asset account. When the government issues
bonds it simply provides the public and institutions with a desirable money
substitute that pays interest i.e. Treasury bonds. It is a swap of one kind of financial
asset for another. To register
this swap the government debits the dollar asset account and credits the bond
account. When the time comes to redeem
(take back) the bonds, all the government does is revers the swap, and that’s
all! When you look at the total amount of finacial assets in the private sector, these remain constant at $ 25 BN after the payment of $ 5 BN taxes. This implies that no lending of financial assets of the private sector to the government has taken place during the swap operation. The money was always there. The debt mountain is an illusion!

Major update 12 December 2015 (v3.0): This new version of the model overhauls the way that incumbent energy source (fossil sources plus biomass, hydro electricity and nuclear electricity) supply capacity is implemented. This is now based on direct (exogenous) input of historical data, with the future supply curve also set directly (but using a separate input array to the historical data). For coal and natural gas fired electricity, this also requires that the simple, direct-input EROI method be used (i.e. same as for coal and NG heating, and petroleum transport fuels).
Note that this new version of the model no longer provides a historical view of the emplacement rates for energy supply sources other than wind and PV, and therefore no longer allows comparison of required emplacement rates for wind and PV with incumbent energy sources. Output data relating to this is available in model version v2.5 (see link below), for the specific transition duration built into that version of the model.
The previous version of the model (version 2.5) is available here.
The original "standard run" version of the model (v1.0) is available here.

A sample model for class discussion modeling COVID-19 outbreaks and responses from government with the effect on the local economy. Govt policy is dependent on reported COVID-19 cases, which in turn depend on testing rates less those who recover
Assumptions
Govt policy reduces infection and economic growth in the same way.
Govt policy is trigger when reported COVID-19 case are 10 or less.
Interesting insights
Higher testing rates seem to trigger more rapid government intervention, which reduces infectious cases.

Overview
This model which simulates the competition of Logging with Mountain Tourism in Derby, Tasmania. This main reason of this simulation is to find if logging will affect the mountain tourism and by any chance they can co-exist.
How the model works.
Both Timber harvesting and mountain tourism can bring the economic contribution to Tasmania. In the Logging industry, it helps increase the need of employment and at the same time logging generate the profit through selling those timbers. In the Mountain Tourism industry, it can get the revenue through couple of ways which include accommodation (approximately 3 days find in paper), Restaurant and parking fee. However, the low growth rate of the trees is not keeping up with the rate of logging, if the trees getting less in Derby mountain, it will affect the sights and the riding experience for tourists, which will affect the satisfaction and expectation as it depends on the sights and experience. The satisfaction and expectation will influence the number of visitors, if they satisfied, they can come again or tell others about the great experience, if not, more and more people will not come again.
Interesting insightsIt seems like logging has no significant negative effect to the mountain tourism, compare the forestry income with the tourism income, tourism income gradually higher than the forestry income at last, which means tourism is in a very important position, as long as the visitors are stable, tourism industry can provide greater economic contribution, stakeholders and governments can find the balance by maintain the status or better slightly reduce logging in order to make them co-exist.

Simple epidemiological model for Burnie, Tasmania
SIR: Susceptible to infection - Infected - Recovery, Government responses and Economic impacts
Government policy is activated when there are 10 or fewer reported cases of COVID-19. The more people tested, the fewer people became infected. So the government's policy is to reduce infections by increasing the number of people tested and starting early. At the same time, it has slowed the economic growth (which, according to the model, will stop for next 52 weeks).

The following is a start to modeling the investment funds and work flow cycle for a company. This simulates how a fixed resource gets distributed among 3 investors and how the investors can lose those funds back to the investment system. The model assumes at this stage that the amount of money available for investment is fixed over the time period in which the dynamics is unfolding. This can be adjusted as the model is further developed.

Overview
The model shows the industry connection and conflict between Forestry and Mountain Tourism in Derby, Tasmania. The objective of this simulation is to find out the balance point for co-exist.
How Does the Model Work?
Both industries can provide economic contribution to Tasmania. Firstly, selling timbers through logging would generate income. Also, spendings from mountain bike riders would generate incomes. However, low tree regrowth rate can not cover up logging, which influences the beautiful vistas and riders' experiences. While satisfaction and expectation depend on vistas and experience, the demand of mountain biking would be influenced through repeat visits and world of mouth as well.
Interesting Insights
Although forestry can provide a great amount of economic contribution to Tasmania, over logging goes against ESG framework as well as creating conflict with mountain tourism. As long as the number of rider visits is stable, tourism can always provide a greater economic contribution compared to forestry. Therefore, the government should consider the balance point between two industries.
Simulation of Derby Mountain Bikes versus Forestry
This model aims to show that how Tasmania government's Covid-19 policy can address the spread of the pandemic and in what way these policy can damage the economy.
This model assumes that if the COVID-19 cases are more than 10, the government will take action such as quarantine and lockdown at the area. These policy can indirectly affect the local economy in many different way. At the same time, strict policy may be essential for combating Covid-19.
From the simulation of the model, we can clearly see that the economy of Burine will be steady increase when government successfully reduces the COVID-19 cased and make it spreading slower.
