Here are the top 6 inventory control techniques:
ABC classification is also referred to as the “Always Better Control” framework based on the Pareto principle. The Pareto principle states that 80% of the outcome is derived from 20% of total effort. The Pareto principle is also known as the 80/20 rule.
Unlike the ABC analysis, which classifies products based on their consumption value, VED analysis categorizes material based on their criticality for the business. VED is an acronym vital, essential, and desirable, each one a category. VED is used to classify items for a production schedule.
The FNSD analysis categorizes inventories into four groups based on descending order of usage. FNSD analysis emphasizes turnover: fast (F), normal (N), slow (S), or dead (D).
The VED, FNSD, and ABC analysis are inventory classification methods. Economic order quantity (EOQ) is a calculator used to determine ideal order size to meet demand without overspending. EOQ is calculated to minimize holding costs and excess inventory.
So far, we’ve covered how to classify inventory into different categories and determine the optimum ordering quantity, but what about stock replenishment? The reordering point formula is used to calculate the threshold, or point, at which a stock needs to be ordered to prevent stockout.
Just-in-time (JIT) is an inventory control technique in which goods are purchased from the supplier only after receiving a customer order. It is also known as the zero inventory system.
