CONTOH PENYELESAIAN SOAL REORDER POINT

Summary

This tutorial video explains how to calculate the reorder point in inventory management, focusing on a company’s raw material usage. It demonstrates both manual and computer-based methods, using a simple formula: reorder point = (average usage per period × lead time) + safety stock. Viewers are shown how to calculate the average daily usage, factor in lead time, and add safety stock to determine when to reorder supplies. The video concludes by showing how to implement the calculation in a spreadsheet for efficient tracking, with examples of varying daily usage and reorder points.

Takeaways

• 😀 The video provides a guide on how to calculate the reorder point for a company using both manual and computer-based methods.
• 😀 Reorder point calculation is essential for businesses to ensure they have enough inventory to meet demand without overstocking.
• 😀 The reorder point formula is based on average usage (or consumption) per period, multiplied by the lead time, plus the safety stock.
• 😀 The average usage per period is calculated by adding up the weekly consumption and dividing it by 7 (for a 7-day week).
• 😀 Lead time (the time it takes for a supplier to deliver goods) is a key factor in calculating the reorder point, which, in this case, is 3 days.
• 😀 The safety stock is the extra inventory kept on hand to prevent stockouts and is 50 units per week in this example.
• 😀 To calculate the reorder point, the formula used is: (average usage per period) * lead time + safety stock.
• 😀 For the example provided, with a weekly average usage of 140 units and a lead time of 3 days, the reorder point is 110 units.
• 😀 The video also demonstrates how to calculate the reorder point using spreadsheet software, which simplifies the process.
• 😀 The method can be adjusted to account for variations in usage or lead time, as shown with different weekly consumption scenarios.
• 😀 Understanding and correctly calculating the reorder point helps companies avoid stockouts and optimize inventory management.

Q & A

What is the main topic of the video?

The main topic of the video is how to calculate the reorder point in inventory management, both manually and using a computer application.

What is a reorder point and why is it important?

A reorder point is the inventory level at which a new order should be placed to replenish stock before it runs out. It is important to ensure that the company does not run out of essential materials and can continue operations without delays.

What is the formula for calculating the reorder point?

The formula for calculating the reorder point is: Reorder Point = (Average Usage Per Day * Lead Time) + Safety Stock.

How is the average usage per period calculated in the example?

The average usage per period is calculated by summing up the daily usage for each day of the week (Monday to Sunday) and dividing by the number of days the company operates, which is 7 in this case.

What is meant by 'lead time' in the reorder point calculation?

Lead time refers to the number of days it takes for a new order to be delivered from the supplier. In the example, the lead time is 3 days.

How is the safety stock accounted for in the reorder point?

Safety stock is the buffer stock kept to avoid stockouts in case of demand fluctuations or delays in delivery. In the example, the safety stock is 50 units per week, which is added directly to the reorder point.

What is the total reorder point in the example provided?

In the example, the reorder point is calculated as 60 units (average usage for 3 days) plus 50 units of safety stock, which gives a total of 110 units.

What would change if the company operated only from Monday to Friday?

If the company operated only from Monday to Friday, the average usage per period would be calculated using only 5 days of the week, instead of 7. This would result in a different reorder point.

What role does a computer application play in calculating the reorder point?

A computer application simplifies the calculation of the reorder point by automatically computing the average usage, lead time, and safety stock, making the process faster and reducing human error.

What happens if the daily usage fluctuates during the week?

If the daily usage fluctuates, the average usage should be recalculated, and the reorder point will adjust accordingly. The video demonstrates this by showing different daily usages and adjusting the reorder point for those fluctuations.
