Main Concepts
There are 4 main components: Elements (the data)
› Products, Customers, …
Time› January, February, …
Formula› Sales February = Sales January + Sales January * 0.5)
Component = <Elements, Time, Formula>› Component Sales
› Component Expenses
› Component Results
Sales Expenses
Results
In order to simulate the Results it is necessary to simulate the Sales and the Expenses

Formula: Sales February = Sales January + Sales January * 0.5)
ComponentA simulation component is one of these tables where the values are calculated.

Parameters
In order to obtain more interesting formulas we will need parameters:
Sales February = Sales January + Sales January * growth index)

Multidimensional Parameters
The parameters must have the possibility of changing their values between products, months, etc. growth index (Apple) = 0.5 growth index (Banana) = 0.6
The use of combinations must be possible: growth index (Apple, January) = 0.55 growth index (Banana, January) = 0.65

Order of resolution
To solve the order of resolution the concept of scope must be introduced: Parameter: growth index
› 1 Find by: Product, Month› 2 Find by: Product
growth index (Apple) = 0.5 growth index (Apple, January) = 0.55

Parameters maintenance
The parameters tables, and maintenance applications are automatically generated (if it is necessary) from the simulation definition.
