Certification in Inventory Control Management

Inventory Control Management is a core capability in materials management, production operations and supply chain management. This course provides a structured introduction to inventory management, inventory control, materials management, Economic Order Quantity (EOQ), ABC Analysis, VED Analysis, production quantity models, quantity discounts, safety stock and reorder point calculations.

The course combines inventory-management concepts with calculations and extensive problem-solving practice. You will begin by understanding the role of materials management, its objectives and responsibilities, before examining what inventory is, the major components of inventory and the relationship between inventory and supply chain management.

From there, the course moves into the analytical techniques used to classify, plan and control inventory.

A practical way to understand the overall inventory-control process is:

Inventory Requirement → Classification → Order Quantity → Order Cycle → Safety Stock → Reorder Point → Cost Analysis → Inventory Decision

This framework connects the major concepts covered throughout the course and helps you understand how individual inventory-control techniques contribute to better materials-management decisions.

Materials Management and Inventory Fundamentals

Effective inventory control begins with understanding the wider materials-management environment.

You will explore the objectives of materials management, the responsibilities involved in managing materials and the fundamental meaning of inventory. The course also examines the different components of inventory and how inventory connects with the broader supply chain management process.

These foundations are important because inventory decisions affect the availability of materials, the timing of replenishment and the way organizations manage resources throughout their operations.

Inventory Control and Classification Techniques

The course then introduces the principles of inventory control and two important inventory-classification approaches: ABC Analysis and VED Analysis.

You will study ABC Classification with an example and calculations, helping you understand how inventory items can be differentiated rather than managed identically.

The course also examines the advantages and limitations of ABC Analysis, providing a balanced understanding of where this approach can be useful and where its limitations should be recognized.

You will then explore VED Analysis — Vital, Essential and Desirable classification. This provides another perspective for categorizing inventory according to its importance.

Together, these approaches demonstrate an important inventory-control principle:

Different inventory items may require different levels of management attention.

Economic Order Quantity — EOQ

A major part of the course focuses on Economic Order Quantity, one of the central quantitative concepts in inventory management.

You will examine:

• Economic Order Quantity models

• Assumptions of the basic EOQ model

• Inventory order cycles

• EOQ cost-model formulas

• EOQ cost-model graphs

• EOQ calculations

The EOQ section helps connect inventory decisions with the costs associated with ordering and maintaining inventory.

Rather than treating order quantities as arbitrary decisions, EOQ introduces a systematic approach to thinking about the relationship between inventory quantity and cost.

A useful decision flow is:

Inventory Requirement → Ordering Decision → Cost Model → EOQ Calculation → Order Quantity Decision

The course also includes a dedicated section containing three EOQ exercises, allowing you to reinforce the concepts through numerical problem solving.

Production Quantity Model

Inventory decisions can differ when inventory is replenished through production rather than through a simple ordering process.

For this reason, the course covers the Production Quantity Model, including:

• Production Quantity Model concepts

• Production Quantity Model graph

• Production Quantity Model formula

• Example and calculations

This expands your understanding beyond the basic EOQ model and introduces another quantitative approach to inventory decisions.

By studying both EOQ and production quantity models, you can better understand how inventory-control models change according to the way inventory becomes available.

Quantity Discount Models

Purchasing decisions may also change when different order quantities are associated with quantity-based pricing conditions.

The course therefore introduces Quantity Discounts, including:

• Quantity discount concepts

• Quantity discount model graphs

• Quantity discount examples

• Quantity discount calculations

This section strengthens your ability to evaluate inventory decisions where order quantities and purchasing-cost considerations interact.

A useful way to approach these decisions is:

Order Quantity → Applicable Discount → Inventory Cost Consideration → Comparison → Decision

This reinforces an important principle: the lowest purchase price does not automatically represent the complete inventory decision. Inventory decisions should be examined using the relevant model and associated cost considerations.

Safety Stock and Reorder Point

Inventory-control decisions are not limited to determining how much inventory to order.

You must also consider when inventory should be replenished and how inventory systems can respond when demand varies.

The course therefore covers:

• Safety stock

• Reorder point

• Variable demand

• Reorder-point analysis under variable demand

Safety stock provides an additional inventory buffer, while the reorder point helps determine when replenishment activity should be initiated.

These concepts can be connected through a simple operating logic:

Demand → Inventory Consumption → Safety Buffer → Reorder Trigger → Replenishment

Understanding this relationship helps connect inventory levels with operational replenishment decisions.

50 Inventory Control Exercises and Solutions

One of the strongest practical components of the course is the dedicated section containing 50 Inventory Control Exercises and Solutions.

These exercises provide extensive opportunities to reinforce the concepts presented throughout the course and strengthen your ability to work through inventory-management problems systematically.

Instead of stopping with definitions and theory, the course gives you repeated practice in approaching inventory-related exercises, evaluating information and working toward a solution.

A practical problem-solving framework is:

Understand the Problem → Identify the Relevant Inventory Concept → Organize the Information → Apply the Appropriate Model → Calculate → Review the Result → Make the Inventory Decision

Repeated practice helps transform inventory-management terminology into a more structured analytical process.

Build a Structured Approach to Inventory Decisions

Inventory control involves several connected decisions.

You may need to determine:

What inventory exists?

How should inventory items be classified?

How much should be ordered or produced?

When should replenishment occur?

How much safety stock may be required?

How do cost relationships affect the decision?

The course brings these questions together through inventory-classification techniques and quantitative inventory models.

The learning progression can be summarized as:

Materials Management → Inventory Fundamentals → Classification → EOQ → Production Quantity → Quantity Discounts → Safety Stock → Reorder Point → Practice

This progression helps you move from basic inventory concepts toward increasingly analytical inventory-control decisions.

From Inventory Data to Inventory Decisions

The central idea of effective inventory control is not simply to maintain inventory. It is to make structured decisions about inventory.

Throughout the course, you can use the following learning framework:

Identify → Classify → Quantify → Replenish → Protect → Evaluate

Identify what inventory is being managed.

Classify inventory using appropriate methods such as ABC or VED Analysis.

Quantify inventory decisions using EOQ, production quantity and quantity discount models.

Replenish inventory using order-cycle and reorder-point concepts.

Protect operations through safety-stock considerations.

Evaluate the results through calculations, examples and structured exercises.

By the end of the course, you will have developed a broader understanding of Inventory Control Management, supported by classification techniques, quantitative models and extensive exercise-based practice.
