The dynamics of unsustainable power usage with constant power generation and consumption rates.

This model simulates a power grid with it's power being consumed by homes and shopping malls. The unit "Kilowatt" is being used to represent an amount of energy (power). The "Power Grid" stock represents the total amount of power that is available at any given time. The “Power Generation” inflow is the amount of power being added to the “Power Grid” based on the “Power Generation Rate”. The “Houses consuming power” and “Shopping malls consuming power” outflows is the amount of power that is being used by the houses and shopping malls based on their respective consumption rate variables. By default it shows an unstable use of power which illustrates how the power grid runs out of power within 24 hours. However, the sliders can be moved around to see how a sustainable amount of power usage can lead to a increase in power held in the power grid.

​Purpose
Enables the different components in the 5 capability model in a visual manner for Enterprise and Business Architecture stakeholders.  

Enter volumes based on transactions from all your applications based on the business process layer.  Actual transaction volumes recorded for your expense or revenue stream.  Example; how many applications are sponsored by engineering that allow CREATE and UPDATE of a supplier or customer.  Enter the number of transactions in the engineering variable.  The engineering group has no authority to create either a supplier or customer.  All organizations are allowed to submit a certain set of inputs for a super user group to review and then those super users create and update the master record.  

Food for thought, the difference between the records created by the super user group and the volume of created party management records is the opportunity to scale and protect the reputation of your client.  

Now lets do the same for every update to a party management record.  All changes to a supplier or customer could effect pricing and tax or duty fees and each must use the formal change management process with many changes needing to have an authorized representative from the supplier or customer.  Digital records are in need of key control designs.  These are monitored and reported to the SEC.  

BUSINESS ARCHITECTURE 

5 Capability Model
The 5 capability model has many stock and flow children which each organization will need to model based on their current state.  

  • Aligns to APQC Process Framework
  • Aligns to Principles in ISO 9001, 26000 and 27001 

ENTERPRISE ARCHITECTURE 
Aligns Zachman Framework Enterprise and Business Architecture with Executive and Leaders from a business management level across any organization.  

A method in which to align and benchmark any organization or agency, with the system(s) logic required from Architects in Row 3, to enable Row 4 engineers who need to supply physics. 


Semantic
Getting terms to align to the generic objects can be a trying task, unless you simply list the stakeholders "semantic" term below the stakeholder in the presentation layer by order shown in the business process management section above the capability management group.

​Physical meaning of the equations
The Lotka–Volterra model makes a number of assumptions about the environment and evolution of the predator and prey populations:

1. The prey population finds ample food at all times.
2. The food supply of the predator population depends entirely on the size of the prey population.
3. The rate of change of population is proportional to its size.
4. During the process, the environment does not change in favour of one species and genetic adaptation is inconsequential.
5. Predators have limitless appetite.
As differential equations are used, the solution is deterministic and continuous. This, in turn, implies that the generations of both the predator and prey are continually overlapping.[23]

Prey
When multiplied out, the prey equation becomes
dx/dt = αx - βxy
 The prey are assumed to have an unlimited food supply, and to reproduce exponentially unless subject to predation; this exponential growth is represented in the equation above by the term αx. The rate of predation upon the prey is assumed to be proportional to the rate at which the predators and the prey meet; this is represented above by βxy. If either x or y is zero then there can be no predation.

With these two terms the equation above can be interpreted as: the change in the prey's numbers is given by its own growth minus the rate at which it is preyed upon.

Predators

The predator equation becomes

dy/dt =  - 

In this equation, {\displaystyle \displaystyle \delta xy} represents the growth of the predator population. (Note the similarity to the predation rate; however, a different constant is used as the rate at which the predator population grows is not necessarily equal to the rate at which it consumes the prey). {\displaystyle \displaystyle \gamma y} represents the loss rate of the predators due to either natural death or emigration; it leads to an exponential decay in the absence of prey.

Hence the equation expresses the change in the predator population as growth fueled by the food supply, minus natural death.

Goal Seeking With Delay
There is much we can learn from the development of qualitative relationships models though once we begin to ask questions like how long, how much, when, etc., a qualitative most is not likely to be of much use. The following video demonstrates how, in a very simple goal-seeking structure with delay, depending on the delay, it can be almost impossible to intuit the implications of the interactions with any level of accuracy. The difficulty arises essentially from operating with outdated data. See also Archetypes.

If private bond holdings are going down and the government is running a big deficit then the central bank has to monetize bonds equal to the deficit plus the decrease in private bond holdings.  We don't show the details of the central bank buying bonds here, just the net results.
