Calculation of relative intensity value

Task

The average annual population of the Russian Federation in 2013 was 143.3 million people,

number of births – 1 895 822,

the number of deaths is 1,871,809.

Determine the relative intensity of the indicators of the natural movement of the population of the Russian Federation for 2013.

Decision:

Relative intensity values characterize the degree of saturation of a certain medium by the studied phenomenon. They represent the ratio of oppositely named but interconnected quantities and are calculated as the ratio of the magnitude of the phenomenon under study to the volume of the environment in which the phenomenon develops.

To solve the problem, we determine the birth rate of children in 2013 and the death rate.

Thus, the birth rate of children in Russia per 1,000 people in 2013 was 13.2 people, and 13.1 people died per 1,000 people, therefore, the natural increase was 0.1 ppm:

K natural growth u003d K p – K cm u003d 13.2 – 13.1 u003d 0.1.

My tasks

1. The task of choosing a supplier

A company located and trading in Moscow has the opportunity to buy goods from both Moscow and St. Petersburg suppliers.

Based on the analysis of the total cost, make a decision on the expediency (or inexpediency) of purchasing goods from a supplier located in St. Petersburg.

Table – Initial data for solving the problem.

Name of indicator unit of measurement Meaning
Tariff for the delivery of 1 m 3 of cargo from St. Petersburg RUB/m 3
Interest on a loan raised to pay for goods % year
Increasing the lead time for the purchase of goods in St. Petersburg days
Purchase price of 1 m3 of goods in St. Petersburg RUB/m 3
Purchase price of 1 m 3 goods in Moscow RUB/m 3
When purchasing goods in St. Petersburg, the company incurs additional costs for cargo handling RUB/m 3
When purchasing goods in St. Petersburg, the company incurs additional costs for cargo insurance, calculated as a percentage of its value % 1.5

Decision:

1) 365 – 12%

15-x

x = 0.5%

2) 36000 * 0.005 u003d 180 (rubles) – interest on the loan

3) 36000 * 0.015 = 540 (rubles) – for insurance

4) 36000 + 2820 = 38820 (rubles) – expenses in St. Petersburg

In Moscow, there are no additional costs, therefore, 39,600 rubles. – total costs.

Costs in St. Petersburg are less by 39600 – 38820 = 780 rubles.

It can be concluded that it is more profitable to buy goods from a St. Petersburg supplier, but maybe from Moscow.

2. The problem of determining the share of costs.

The goods are delivered to the company’s warehouse from a non-resident supplier, first by rail and then by road. Shipping cost items are provided in the table.

Table – Cost items for the delivery of goods.

Name of indicator unit of measurement Meaning
Unit purchase price of goods RUB/m 3
Tariff for the carriage of goods by rail RUB/m 3
Tariff for the carriage of goods by road RUB/m 3
Estimated delivery time Days
Interest rate on capital invested in stocks %/year
Additional costs for cargo insurance, calculated as a % of its value %

Determine the share of the total cost of delivering goods from a non-resident supplier in the cost of the delivered goods.

Decision:

1) 365 days – 12%

16 days – x %

x = 16*12/365 = 0.5%

2) Additional costs: 5000 * 0.01 = 50 (rub.)

3) 5000 * 0.005 u003d 25 (rubles) – for invested capital

4) 120 + 600 + 50 + 25 = 795 (rubles)

5) Share of total costs: 795/5000*100 = 15.9%
