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.

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:

kдет + Kmoh, (5.9)

Where Kdet - cost of materials, expenses for manufacturing dezagregirujushchego devices for modernisation of a dynamic separator, Kdem=604,52 thousand rbl.; Kmon - expenses for installation dezagregirujushchego devices, Кмон=15%КДет;

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

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 (Q2> Q1) 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 C1 - 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> B1и TS = Ц2,

Changes of monetary inflow:

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.

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.
