Question

Плановая годовая потребность в металле составляет 2 тыс. тонн, стоимость 1 тонны металла – 1, 5 тыс. ден. ед., интервал между поставками – 30 дней. Страховой запас принимается в размере 50 % текущего запаса, время на разгрузку и подготовку материала к производству – 2 дня. Определите норму запаса в днях, исходя из среднего текущего запаса и норматив оборотных средств по производственным запасам.Примечание: расписать с формулами.

Answer 1

Объяснение:

Норма запаса в днях:                                                                                     Нзап = Зтек + Врп + Зстрах ,              

Зтек –средний текущий запас (определяется как половина интервала между поставками), дни; по условию 30 дней интервал между поставками , значит Зтек=30:2=15 дней

Врп – время на разгрузку и подготовку материала к производству, дни, по условию 2 дня  

Зстрах – страховой запас, дни, по условию 50% от текущего запаса , т.е.  15 : 2 = 7,5 дней , берем 8 дней по правилу округления. и получаем

15 + 2 + 8 = 25 дней

Норматив оборотных средств по производственным запасам (Wпз), ден. ед.:

                        Wпз= Всут*Нзап*Цм,

где

Всут - суточная норма запаса

Нзап - норма запаса , дни

Цм – цена единицы материала, ден. ед.

По условию :

Годовая норма - 2000 т

Цена 1 тонны - 1,5 тыс. ден. ед. = 1500 ден. ед.

Всут. = Годовая потребность / количество дней в периоде

Всут = 2000/360 =5.6 т

Wпз= 5,6 * 25 * 1500 = 210 000 ден. ед.

Answer 2

Calculation of Average Current Inventory

To determine the average current inventory, we need to consider the planned annual metal requirement, the delivery interval, and the time required for unloading and material preparation.

The planned annual metal requirement is 2,000 tons, and the delivery interval is 30 days. This means that the company receives metal deliveries every 30 days.

The time required for unloading and material preparation is 2 days.

To calculate the average current inventory, we need to consider the delivery interval and the time required for unloading and material preparation.

The formula to calculate the average current inventory is as follows:

Average Current Inventory = (Delivery Interval + Time for Unloading and Material Preparation) / 2

Substituting the given values into the formula:

Average Current Inventory = (30 + 2) / 2 = 32 / 2 = 16 days

Therefore, the average current inventory is 16 days.

Calculation of Safety Stock

The safety stock is the additional inventory maintained to mitigate the risk of stockouts due to unexpected fluctuations in demand or supply.

In this case, the safety stock is taken as 50% of the current inventory.

The formula to calculate the safety stock is as follows:

Safety Stock = 50% of Average Current Inventory

Substituting the value of the average current inventory (16 days) into the formula:

Safety Stock = 50% of 16 days = 0.5 * 16 = 8 days

Therefore, the safety stock is 8 days.

Calculation of Reorder Point

The reorder point is the inventory level at which a new order should be placed to replenish the stock.

To calculate the reorder point, we need to consider the average lead time, which is the time between placing an order and receiving the delivery.

In this case, the average lead time is the sum of the delivery interval and the time required for unloading and material preparation.

The formula to calculate the reorder point is as follows:

Reorder Point = Average Lead Time * Average Daily Usage + Safety Stock

Since the average daily usage is not provided in the question, we cannot calculate the reorder point without this information.

Please provide the average daily usage so that we can calculate the reorder point accurately.

Answer 3

Calculation of Average Current Inventory

To determine the average current inventory, we need to consider the planned annual metal requirement, the delivery interval, and the safety stock.

The planned annual metal requirement is given as 2,000 tons.

The delivery interval is 30 days.

The safety stock is taken as 50% of the current inventory.

To calculate the average current inventory, we can use the following formula:

Average Current Inventory = (Planned Annual Requirement / Delivery Interval) + Safety Stock

Let's substitute the given values into the formula:

Average Current Inventory = (2,000 tons / 30 days) + (0.5 * Average Current Inventory)

Simplifying the equation:

Average Current Inventory - 0.5 * Average Current Inventory = 2,000 tons / 30 days

0.5 * Average Current Inventory = 2,000 tons / 30 days

Average Current Inventory = (2,000 tons / 30 days) / 0.5

Average Current Inventory = 66.67 tons / day

Therefore, the average current inventory is 66.67 tons per day.

Calculation of Inventory Days

To determine the inventory days, we need to divide the average current inventory by the normative working capital for production inventory.

Unfortunately, the normative working capital for production inventory is not provided in the question. Without this information, we cannot calculate the inventory days accurately.

Please provide the normative working capital for production inventory, and I will be happy to assist you further.
