AccountBasic model of an account with optional interest |

This information is part of the Business Simulation Library (BSL).
The output y reports the balance of an account that is increased or decreased by flows connected to the stock ports or at given rates (u_plus
and u_minus
respectively) if hasRateInputs = true
. When there are interest payments (withInterest = true
) positive and negative balances of the account will lead to interest earned and interest paid, respectively. The associated fractional rates can be given either as constants or as variable inputs.
hasNetRateInput = true
the rate of flow for the account can be given as a netRate using the connector u_plus
only.Account
is a more general structure than the widely known bathtub [6, pp.10f.] initialBalance |
Value: 0 Type: Money (CU) Description: Initial balance of the account |

hasRateInputs |
Value: true Type: Boolean Description: = true, if input connectors should allow giving transaction rates increasing/decreasing the balance of the account |
hasNetRateInput |
Value: false Type: Boolean Description: = true, if the rate of flow is given a net rate (u_plus only) |
withInterest |
Value: false Type: Boolean Description: = true, if positive and negative balances lead to interest earned or paid |
hasConstantInterest |
Value: true Type: Boolean Description: = true, if the optional interest rates are given as constant parameters |
