2.3. Statement of the solvable task 3
Here we use the following notations:
- SI — sources of income (shares in construction of houses);
- PPI — payback period of investment.
General properties of the task:
- task type — 7;
- payback factor — return on investment;
- option of SI behavior on initial ranges of their exploitation:
- changing specific income from exploitation (option 1);
- random delay of the start of exploitation (option 2);
- the need for statistical modeling:
- for option 1 — not is;
- for option 2 — is.
Given:
- for option 1:
- number of investment options, for each of them are given:
- investment amount, which consists of two parts:
- investor's own funds;
- credit funds, involved by him;
- investment amount, which consists of two parts:
- interest rate on the loan;
- payback parameters:
- PPI;
- rate of return during PPI on the consumed investment amount;
- number of SI types, for each of them are given:
- SI sample description;
- minimum and permissible numbers of being acquired SI samples;
- cost of one SI;
- expected specific income (per time unit) from exploiting one SI in stationary mode;
- number of points of a tabular function of reduction ratio for specific income from SI non-stationary exploitation, for each of them are given:
- value of argument: a current time of SI exploitation;
- value of function;
- number of investment options, for each of them are given:
- for option 2:
- investment amount, which consists of two parts:
- investor's own funds;
- credit funds, involved by him;
- interest rate on the loan;
- payback parameters:
- PPI;
- maximum and minimum values of a rate of return during PPI on the consumed investment amount;
- number of its values;
- number of SI types, for each of them are given:
- SI sample description;
- minimum and permissible numbers of being acquired SI samples;
- cost of one SI;
- expected specific income from exploiting one SI in stationary mode;
- number of points of a tabular function of distributing a random delay of the start of SI exploitation, for each of them are given:
- value of argument: a current time of owning SI;
- value of function.
- investment amount, which consists of two parts:
Maximized quality criterion: relative income (per time unit) from SI exploitation.
