Collection of practical tasks for the discipline "Quality Management".
Situation 1.
The introduction of a rationalization proposal at the enterprise will improve the quality of products and increase the annual output by 500 products. The price of the product before the implementation of the rationalization proposal was 3000 rubles, and after the implementation - 3200 rubles. Determine the annual economic effect from the implementation of the rationalization proposal by the enterprise, taking into account that the initial version of the production of products was equal to 2500 pieces.
Situation 2.
At the enterprise, n = 100 batches of 250 items in each were subjected to complete control. The control results are shown in the table.
Д 0 1 2 3 4 5 6 7 8 9 10 14 1 20
Мр 4 9 18 24 17 11 5 3 2 2 2 1 1 1
mТД 2 8 15 20 20 15 10 2 3 1 0 0 0 0
where: mD is the number of lots with D defective products.
The acceptable level of quality at the enterprise is accepted at 0,09.
Determine: the supplier's risk of receiving defective lots.
Situation 3.
The workshop produces light bulbs at the light bulb factory. To check their quality, 30 lamps are selected and tested on a special stand. The test results are presented in the table.

Determine the average duration of lamp burning.
Situation 4.
When testing a transistor at an electronic equipment factory, the failure rate is determined in the range of 2000 - 3000 hours. Testing of 5 groups of transistors of 300 items for 2500 hours was carried out.
The test results are presented in the table.

4 5 3 8
5 4 2 6
Determine the failure rate of transistors for 2500 hours of operation.
Situation 5.
The reduced costs for the production of 1 motor at the plant in 1998 amounted to 7000 rubles. The introduction of a new technological process in the 1st quarter of 1999, 1999, made it possible to reduce the reduced costs to 6500 rubles.
Determine the economic effect in 1999 from the introduction of a new technological process if it is known that the plant's program for 1999 is 10000 motors.
Situation 6.
The plant sells radio receivers manufactured by it at the price of 1000 rubles, bearing manufacturing costs up to 20% of the selling price. Dealers' expenses for the purchase of radios for transportation and storage are up to 10% of their selling price.
At what price do they need to sell receivers in order to have an economic effect from their transactions not less than the economic effect of the manufacturer?
Situation 7.
The introduction of the invention made it possible to reduce the cost per unit of production by 100 rubles. The initial cost of the product was RUB 1500. The annual production volume at the enterprise was 10000 pieces.
One-time costs for the development and implementation of the invention amounted to 20000 rubles.
Determine the annual economic effect from the introduction of the invention.
Situation 8.
According to the report for 1998, the plant had the following indicators:
The prime cost of rejected products, semi-finished products and other material values is 300 thousand rubles.
The cost of correcting the marriage was 5 thousand rubles.
Defective products sold to the Vtorsyrya enterprise - 120 thousand rubles.
The amount of deductions from employees who made a marriage - 10 thousand rubles.
Amounts collected from suppliers of low-quality materials - 150 thousand rubles.
Determine the amount of losses from rejects at the plant in 1998
