Problem 1: Selecting the type of transport

Condition of the problem.

Kazakh company has assembly plant in South-East Asia. A wide range of component parts regularly sent from Kazakhstan assembly plant. In this case, the question often arises: how to transport cargo by air or by sea?

Factors that play a decisive role in choosing between air or sea transport are:

- Freight rate during transportation by sea - 250 USD for 1 m3;

- Freight rate for air transport - 1154 USD for 1 m3;

- Journey time for the carriage of sea transportom1 - 50 days;

- Journey time for the carriage of air transportom2 -10 days;

- Additional insurance stocks on the assembly business in the case of transport by sea - 14 days;

- The interest rate on the stocks of goods in transit during transportation by sea and air - 7% per annum;

- Additional costs for the assembly business reserves - 15%.

In our example, the freight rate air transport is higher than on the sea. However, air transport products in the path is not as long as in the waterway, so the cost of interest in connection with resources in transit and insurance stocks on the stock assembly business below.

Determine what type of transportation will choose the company at a specific value of the goods, equal to 5 000 USD, 10 000 USD, 50 000 USD.

Problem 2: selecting suppliers

Condition of the problem.

Kazakh company specializes in the production of household appliances and its regularly confronted with the question of where to buy component parts - in Kazakhstan or in Southeast Asia? For example, in the case of shipments from Southeast Asia to overcome long distances than with shipments from Kazakhstan. Transportation costs will be significantly higher and longer periods require additional transportation stocks in supply chain and additional insurance stocks to ensure uninterrupted production. Moreover, products from the region of Southeast Asia is subject to import duties. Table. 7.1 lists additional factors that arise when shipped from South-East Asia.

Table 7.1

Additional factors that arise when products are shipped from the region of Southeast Asia *

Factors name	Value
Cargo transportation tariff by sea	150 USD for 1 m3
Import fee on the import of goods	12%
Interest rate on reserves: On the move Insurance	10% 10%
Transport duration	25 days
Additional insurance reserves completing the recipient	7 days

The unit cost (price) of goods is 4 000 USD, 6 000 USD, 8 000 USD, 10 000 USD, 12 000 USD per 1 m³.

Price components in Kazakhstan is 20% higher than in the region of Southeast Asia, and their quality is the same.

Based on these factors and the specific value of the goods to determine the additional costs arising from the shipments from Southeast Asia. Comparing costs for the purchase of components in Kazakhstan and in Southeast Asia, to choose a supplier of goods.

Problem 3. Selection of containers for transportation of products Condition of the problem.

Products are transported in standard containers in boxes or trays. If trays are used, it fits 300 pieces into the container (25 pallets in one container 12 on a pallet of products). If boxes are stacked, fit 480 products in a container (40 boxes in one container 12 of products in a single box). Transportation costs per container:

-During transportation to 100-249 km - 500 USD, -During transportation to 250-499 km - 800 USD, -During transportation to 500-999 km - 1200 USD, -During transportation to the 1000-1999 km - 2000 $, -During transportation for 2000 km or more - 3000 $ The hourly rate of loading and unloading (RRP): -Manual - 36 USD, -Fork lift - 54 USD The costs of the working time for loading: -One pallet: manually - 4.8 minutes, fork lift - 2.4 minutes; -One box: Manual - 1.8 m, fork lift - 0.9 min. Necessary to determine the costs per pallet, and one box for transportong products in each of these distances, based on calculations - choose the most efficient type of packaging.
