I made this model to simulate how a companies revenue will change depending on the lifetime of the appliances it manufactures, in combination with the ratio of repair costs and price. It also shows the accumulation of e-waste.
This model was proposed in a regulatory framework in Brazil. Its main idea is the obtainment of a dynamic control model to avoid the related parties issues on regulated public services over contract extensions. As the terminal condition of these contract extensions is NPV=0, the firms would have an incentive to contract related parties to inflate costs, and diminish their profits, in order to request a larger time extension. So, this system creates a stable "shadow" based on the 5 years before these extensions, where the company did not have such incentives.
Modern industrial civilisation has created massive
interdependencies which define it and without which it could not function. We all
depend on industrial farming to produce the food we eat, we depend on gasoline
being available at the gas station, on the
availability of electricity and even on the bread supplied by the local baker. Naturally,
we tend to support the institutions that supply the amenities and goods to
which we have become accustomed: if we get our food from the local supermarket,
it is likely that we would be opposed to it’s closure. This means that the economic
system that relies on continuous growth enjoys implicit societal support and that
nothing short of environmental disaster or a shortage of essential raw
materials will impede it’s growing indefinitely. It is not hard to work out the
consequences of this situation!

COVID-19 Outbreak in Burnie Tasmania Simulation Model
Introduction:
This model simulates the COVID-19 outbreak situation in Burnie and how the government responses impact local economy. The COVID-19 pandemic spread is influenced by several factors including infection rate, recovery rate, death rate and government's intervention policies.Government's policies reduce the infection spread and also impact economic activities in Burnie, especially its tourism and local businesses.
Assumptions:
- This model was built based on different rates, including infection rate, recovery rate, death rate, testing rate and economic growth rate. There can be difference between
this model and reality.
- This model considers tourism and local business are the main industries influencing local economy in Burnie.
- Government's intervention policies will positive influence on local COVID-19 spread but also negative impact on local economic activity.
- When there are more than 10 COVID-19 cases confirmed, the government policies will be triggered, which will brings effects both restricting the virus spread and reducing local economic growth.
- Greater COVID-19 cases will negatively influence local economic activities.
Interesting Insights:
Government's vaccination policy will make a important difference on restricting the infection spread. When vaccination rate increase, the number of deaths, infected people and susceptible people all decrease. This may show the importance of the role of government's vaccination policy.
When confirmed cases is more than 10, government's intervention policies are effective on reducing the infections, meanwhile local economic activities will be reduced.
