# Calculation of economic efficiency from use dezagregirujushchego devices on Open Society «Shebekinsky cretaceous mill»

The purpose of the given calculation is acknowledgement of economic feasibility of use dezagregirujushchego devices in a sort mnogozahodnyh tapes which allows to raise an overall performance of a dynamic separator.

Calculation of economic efficiency from device introduction on Open Society «Shebekinsky cretaceous mill» by a known technique [59] is more low presented.

Initial data for economic efficiency calculation are placed in table 5.4.Table 5.4

Initial data for calculation

Indicator | Marking-off | Units | To Modernisations | After Modernisations |

Productivity of the equipment | Q | t/ch | 7 | 7,36 |

An equipment coefficient of utilisation in time | Kek | - | 0,68 | 0,68 |

Effective fund of an operating time of the equipment, ch. | ^{Tef.m} | mash.ch | 5956,8 | 5956,8 |

G odovoj output volume | AND | t | 41697,6 | 43842 |

Unit cost price | WITH | Rbl. | 2573,7 | Calculation see |

G odes of delivery of the equipment in operation | Year | 2001 | 2001 | |

Size standard of depreciation on full restoration | N | % | 8 | 8 |

Capital investments on equipment modernisation | ΔK | Thousand rbl. | - | 695,2 |

Size standard of discount - Е=0,2; calculation Horizon - _{Tok.ust} = 1 year; Number of a step of calculation, year - t=1.

Capital investments necessary for equipment modernisation it is defined according to a technique.

Additional capital investments AK:

^{k} =К_{дет} + K_{moh}^{, (5}.^{9)}

Where _{Kdet} - cost of materials, expenses for manufacturing dezagregirujushchego devices for modernisation of a dynamic separator, K_{dem}=604,52 thousand rbl.; _{Kmon} - expenses for installation dezagregirujushchego devices, К_{мон}=15%К_{Дет};

_{Kpot} - losses from liquidation of the equipment, component parts and knots.

141

With change of capital investments a fixed capital (AOf) as Of = 0 and _{Kps} = ^{n l}'^{v} changes

Change of the operational expenditure occurs as a result of output increase. At change of productivity of a dynamic separator (Q_{2}> Q_{1}) production gain will make:

Where Q1, Q2 - productivity of a dynamic separator accordingly before introduction, in physical units;

- Base factor of extensive use of the equipment;

Decrease in the cost price of production at the expense of production growth:

Where - conditionally constant expenses in the cost price of a unit of production (shop, manufacturing, on the maintenance and equipment operation) В1, В2 - annual volume of production before introduction.

In connection with growth of a fixed capital we define change of the running charges and operation of the equipment as a result of installation dezagregirujushchego devices in a sort mnogozahodnyh tapes in dynamic separator CSA6 (RSO):

On depreciation:

On capital and operating repair:

On equipment operation

Summaravna:

Decrease in the cost price of production from modernisation:

Cost price decrease per unit of output will make:

The cost price of a unit of production under the project:

Where C_{1} - the full cost price of a unit of production before modernisation

As a result of equipment modernisation there is a change monetary pritokovi monetary outflows

At В2> B_{1}и TS = Ц2,

Changes of monetary inflow:

143

Changes of monetary outflows:

Where - conditionally variable expenses in the cost price of a unit of production to

Introductions, rub;

N - taxes, rbl.

Where ΔΠ - a profit gain, rbl.;

Changes of monetary outflows it is defined on steps:

I G GG h _{fc} ∕ 2

In table 5.5 financial results and the plan of monetary streams which have changed after installation dezagregirujushchego devices are resulted.

Table 5.5

Change of monetary streams and efficiency indicators

III. Profit on production | ΔΠ | Thousand rbl. | 1700,88 |

IV. Net profit minus taxes | n_{t} | Thousand rbl. | 1346,80 |

V. Equipment Depreciation | And | Thousand rub | 55,62 |

VI. Discounting Factor | α_{t} | - | 0,833 |

VII. The Pure discounted income | NPV | Thousand rbl. | 473,01 |

VIII. A profitableness Index | IP | 1,68 | |

IX. The Time of recovery of outlay (the return period kapvlozheny) | Current | Years | 0,52 |

Profitableness index:

So kaksledovatelno, a variant of modernisation of the equipment

It is effective.

Time of recovery of outlay of capital investments (the period of return of capital investments), years:

As a result of introduction on Open Society «Shebekinsky cretaceous mill» dezagregirujushchego devices the pure discounted income of introduction has made 473 thousand rbl., an index of profitableness 1,68, a time of recovery of outlay 0,52 years.
