If there are several suppliers the transport stock is defined as the weighted average value with taking into account the duration of the transit time and the volume of supply:
|
Volume
of supply
|
The
transit time of the cargo
|
Days
|
|
The 1-st
supplier
|
20
|
15
|
|
The 2-nd
supplier
|
30
|
14
|
|
The 3-rd
supplier
|
10
|
12

Ttrans
=
(20 ×15 + 30 × 14 + 10 ×12) /(20 + 30 + 10) = 14 days
The
current warehouse stock
of material assets is the stock which provides the needs of
manufacturing for the period between their two regular intakes.
The
structure of circulating assets
includes the average current stock accepted at the rate of 50 % from
duration of the interval between two adjacent deliveries:
Tcur
= I / 2 ,
where
I
- the duration in days of the interval between deliveries.
The average
interval between deliveries can be calculated according to the
following formula:
I = 360(180, 90) / ND ,
where
ND
- the number of deliveries during the period.
The stock
intended for providing the needs of manufacturing in case of the
delay of material assets delivery is referred to
as the guarantee (insurance) stock
of material assets.
Calculating
in different ways the size of
circulating
assets,
which is necessary for their normal work, increases
the efficiency of using this resource.
