What is the best way to determine lead time for a component in MRP?

由人工智能和领英社区提供技术支持

Lead time is a crucial factor in material requirements planning (MRP), the process of calculating the materials and resources needed to produce a product. Lead time is the amount of time it takes to receive a component from a supplier or to make it internally. Knowing the lead time for each component helps you plan your production schedule, avoid stockouts, and optimize your inventory levels. But how do you determine the best way to estimate lead time for a component in MRP? Here are some tips and methods to help you.

1 Use historical data

One of the simplest ways to determine lead time for a component is to use historical data from previous orders or production runs. You can calculate the average lead time by dividing the total time spent on all orders or batches by the number of orders or batches. You can also use the minimum, maximum, or median lead time as a reference. However, historical data may not always reflect the current or future situation, especially if there are changes in demand, supply, quality, or capacity. Therefore, you should update your data regularly and adjust your lead time accordingly.

If we have historical data, this should work. But a periodical review required to keep this field updated.

2 Use supplier information

Another way to determine lead time for a component is to use the information provided by your supplier. Your supplier may have a standard lead time for each component, based on their production process, capacity, and availability. You can also negotiate with your supplier to reduce the lead time or to guarantee a certain delivery date. However, supplier information may not always be accurate or reliable, especially if there are delays, disruptions, or errors in the supply chain. Therefore, you should monitor your supplier's performance and track your orders closely.

3 Use simulation or forecasting

A more advanced way to determine lead time for a component is to use simulation or forecasting techniques. Simulation involves creating a model of your production system and testing different scenarios and variables that may affect the lead time. Forecasting involves using statistical methods to predict the lead time based on historical data and trends. Both methods can help you account for uncertainty, variability, and complexity in your production environment. However, simulation and forecasting may require more data, resources, and expertise than other methods. Therefore, you should validate your results and update your assumptions regularly.

4 Use safety stock or buffer time

A final way to determine lead time for a component is to use safety stock or buffer time. Safety stock is the extra inventory you keep to cover the unexpected demand or supply fluctuations. Buffer time is the extra time you add to the lead time to account for the potential delays or errors. Both methods can help you reduce the risk of stockouts, shortages, or missed deadlines. However, safety stock and buffer time may also increase your inventory costs, storage space, and waste. Therefore, you should balance your safety stock and buffer time with your service level and inventory turnover.

Determining the best way to estimate lead time for a component in MRP depends on your production goals, data availability, and risk tolerance. You can use one or a combination of the methods mentioned above to improve your MRP accuracy and efficiency. What methods do you use to determine lead time for a component in MRP?

Another perspective is to review number of safety dips in a sufficient data points of historical data. Limited number of safety dips should trigger a reduction of safety stock. Higher number of safety dips should trigger an increased level of safety stock

All of these are very relevant points to get a realistic Lead time. Based on the demand, supply patterns and transportation time, a combination above methods should help to project accurate lead time.
