What is inventory planning?

Inventory planning ensures your business has exactly what is needed—no more, no less. It’s the process of managing the quantities and timing of stock to align perfectly with customer demand. It is an important practice, as this translates into a company's ability to satisfy customers without wasting resources.

Inventory decision-making balances the scale of too much and too little through predicting sales, setting reorder points, and maintaining safety stock levels. This prevents the possible scenario of either being overloaded with unsold items or turning customers away because the shelves are empty.

Efficient planning of your inventory gets your operations organized, reduces costs, and enhances customer satisfaction by having in store whatever they may need at any given time.

Overview of inventory policies

To begin our journey towards successful inventory decision-making, let’s define inventory policies. So, what are they?

Inventory policies are the guidelines businesses follow to manage their stock efficiently. These rules help in achieving a proper balance between having enough products to meet customer demand while avoiding overstocking.

There are a number of inventory policies, but the following are some of the most common:

  • Min-max policy: This sets minimum and maximum stock levels to trigger reorders. When inventory drops to the minimum level, a replenishment order should be placed to bring the stock up to the maximum.
  • RQ Policy: This means that when the stock level falls below a designated replenishment point (R), a constant quantity (Q) is ordered.
  • Order on Demand: Through this policy, a minimum quantity is held in the inventory, ordering the product only as customers place the order.
  • Material Requirements Planning: This method schedules material orders based on detailed production planning.
  • Regular Policy: Orders are placed at regular intervals, which can be adjusted to include safety stock to account for unexpected surges in demand.

Each of these strategies is selected based on the needs of a company and its operational goals regarding efficiency and cost-effectiveness within its inventory planning.

How to choose the inventory policy

Selecting the right inventory policy involves understanding your business needs—like demand patterns, lead times, and variability in supply.

anyLogistix provides tools for the simulation of different inventory strategies, showing how each strategy will perform under various scenarios. This capability helps ensure that you select the most effective policy to optimize both efficiency and cost-effectiveness in your supply chain management.

However, there are times when customization is necessary. In that case, we've got you covered—anyLogistix allows you to define any custom inventory policies to meet the specific needs of your business. Note that inventory policies in anyLogistix are available only within simulation-based experiments.

Implementing Material Requirements Planning

Material Requirements Planning (MRP) is a system for efficient control of inventory and the process of production planning. MRP calculates the materials needed and schedules their delivery based on production forecasts to make sure that everything required for manufacturing is available at the right time.

anyLogistix supports MRP by simulating its impact on your inventory system and optimizing the ordering schedules to improve overall inventory planning. This helps in reducing the level of stock while avoiding production losses due to material shortages.

Consider, for example, a company manufacturing bicycles. MRP would determine the exact amount of steel, tires, and seats needed each month, based on the production schedule, to meet customer orders without overstocking.

Managing safety stock

Safety stock is extra inventory on hand to safeguard against sudden rises in demand or delays in supply. This enables a business to continue selling to customers without interruption. anyLogistix helps optimize this buffer by simulating various market scenarios and calculating the ideal safety stock levels. This prevents stockouts and minimizes excess inventory costs in your decision-making process.

A winter coat seller can use anyLogistix to calculate the level of safety stock based on the historical data of sales and forecasted weather, and possibly even the reliability of the suppliers. This ensures they have enough coats during a sudden cold snap without overinvesting in inventory that might not sell.

Maintaining optimal service levels

Service levels significantly impact customer satisfaction and retention, indicating how well a business meets customer demands for product availability and delivery times. High service levels mean customers get what they want at the right time, which builds their loyalty and trust in a brand.

anyLogistix helps achieve this by using advanced simulation tools that analyze and forecast demand patterns. Businesses can optimize their inventory levels accordingly with the right balance that meets customer demand and at the same time minimizes excess stock.

Smart approach to inventory planning

Effective inventory management is a fine balance between meeting your customers’ demands and managing your resources wisely.
