2.3. Statement of the solvable task 3

     Here we use the following notations:

  • SI — sources of income (piece goods);
  • PPI — payback period of investment.

     General properties of the task:

  • task type — 3;
  • diversity of SI profitability — varying (see definit.);
  • option of SI realization — on their definite profitability;
  • option of accounting SI realization period:
    • by its limitation (option 1);
    • by setting its parameters (option 2);
  • number of same-type SI purchased by one request — one;
  • payback factor — return on investment in absence of initial SI;
  • the need for statistical modeling — is.

     Given:

  • 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 values ​​of this rate;
  • for option 1:
    • deadline of realizing acquired SI;
    • condition of presence (yes) or absence (no) of clearance sale with markdown for those SI that are left after the deadline of their realization;
  • for option 2:
    • control period of realizing acquired SI;
    • maximum probability of incomplete realizing SI of each type during this period;
  • number of SI types, for each of them are given:
    • SI sample description;
    • number of submitted requests for realizing SI;
    • minimum and permissible numbers of being acquired SI samples;
    • number of options for SI purchase cost, for each of them are given:
      • minimum and maximum number of SI in a batch;
      • purchase cost of one SI;
    • number of proceeds options for SI realization, for each of them are given:
      • expected proceeds from realizing one SI;
      • expected intensity of entry of requests for SI realization;
    • for option 1 in the presence of clearance sale with markdown for remaining SI:
      • markdown factor for remaining SI at their clearance sale.

     Maximized quality criterion:

  • at restriction of a the period of realizing SI (option 1) and in absence of clearance sale for remaining SI — total proceeds from SI realization;
  • in all other cases — absolute income from SI realization.
