EOQ TRADITIONAL VS DEMAND-BASED METHODS Cost Control Management (MGMT370 U4) Submission

Facing a tough decision to make, to inform the Global Supply Chain Manager about moving to lean manufacturing and generating profitability improvements including improvements in asset requirements. The information that was given was of inventory and figuring out how to make it more profitable by calculating the changeover in the manufacturing plan, the demand per period along with carrying cost of inventory. Additionally assessing the average cost per unit of inventory. The calculation in a traditional forecast-driven manufacturing, could be complex.

Taking into consideration that the ever changing evolution of Global Supply Chain Management affects price and every consumer. Just as there are benefits and costs of globalization, there are similar pros and cons of a global supply chain. In particular, companies need to manage the related risks. With the onset of globalization, managing supply chains has become more complex and business critical than ever before (Milosz M., Oct 4, 2012). When a company’s operations are under its own control, there are fewer moving parts.

As a result, the company has greater access to information. In this type of scenario, it is much easier to identify, quantify, prioritize and mitigate risk for better decision making. In an environment that has become increasingly global in nature, there are more parties involved and less information available at any point in the production process. This makes it much harder to identify, quantify, prioritize and mitigate risk for better decision making (Milosz M., Oct 4, 2012). There are three major factors that impact supply chain risk: Increasing supply chain complexity, decreasing access to information and greater need for higher quality faster, all for a lower cost.

The ability to anticipate and address risk effectively has been severely handicapped by complexity. Now that manufacturers are outsourcing more work to suppliers across the globe and are managing second and third tier suppliers, it has become difficult to track, trace and monitor production (Milosz M., Oct 4, 2012). As companies continue to expand globally, operational decision will be made regardless of whether all the right information is available. Unfortunately, if the proper communication and collaborations systems aren’t implemented, a lack of data correlates directly to an increase in risk (Milosz M., Oct 4, 2012). When organizations don’t have the right information to make an informed decision, a higher level or risk exists that an undesirable outcome will occur (Milosz M., Oct 4, 2012).

Inventory Management also known as Stock Management is a crucial part of Working Capital Management. EOQ is one of the most prominent models used widely for effective inventory management. EOQ calculates the ordering quantity of inventory using inputs of carrying cost, ordering cost, annual usage of the said inventory. Working Capital Management is an important specialized function of Financial Management. Every component of Working Capital such as inventory, debtors or receivable, cash, creditors or payables, short-term debts, etc., needs the effort to manage.

This makes its management critical, compared to other working capital components (Sanjay B.B, Aug 31, 2017). Assuming that: Monthly sales or demand = 1,000 units Changeover cost = $500 Inventory carrying cost = 30% of inventory cost Average cost per unit of inventory = $10 How to calculate EOQ in a traditional forecast-driven manufacturing operation. The formula is as follows: EOQ = sq. root\/ x $500(carry over cost) x 1,000(demand) / $10(Average cost per unit) x 30% (0.3 inventory carry cost) = 333,333.333 EOQ = sq. root \/$1,000,000 / $3.00 = 333,333.333 = 578units ($5,780)

How to calculate EOQ in a demand-based synchronous manufacturing operation. The formula is as follows: EOQ = 2 x $10(avg. cost / unit) x 1,000(demand) / $10(avg. cost / unit of inventory) x 0.3(inventory carry cost) EOQ = sq. root (2 x $10 x 1,000 / ($10 x 0.3)) EOQ = sq. root (20,000 / $3.00) = (81.697units)$6,666.67 Assuming the carrying cost of inventory is 30%, the dollar savings amount of inventory needed is $886.67.

In conclusion, the impact on the company’s overall ROI when switching to demand-based, synchronous manufacturing is very significant. It causes the company to save a substantial amount of money when it comes to calculating numbers for inventory that is in the millions perhaps billions. Significant improvement on inventory, continual fluidity of the manufacturing plant keeping the company competitive in the industry are some of the many factors. Maximization of money coming into the company, reducing inventory and controlling operating expenses, reduces manufacturing lead times. Continuous improvement is key when the demand-based synchronous manufacturing model strategy is employed.

Customer requirements and expectations is possible while operating efficiently and with shorter wait time (Jennifer J., 2004).

Deciding between traditional EOQ (Economic Order Quantity) methods and a demand-based, synchronous manufacturing approach involves analyzing how each impacts inventory management and overall supply chain efficiency. Both strategies aim to optimize inventory levels, reduce costs, and improve responsiveness to customer demand, but they do so through different mechanisms that are suitable for different organizational contexts.

Traditional EOQ models are forecast-driven, relying heavily on historical demand data, fixed ordering costs, and carrying costs to determine optimal order quantities. This method assumes that demand can be accurately predicted and that inventory levels are maintained to buffer against fluctuations. The formula for EOQ in this model considers carrying costs, ordering costs, and demand volume, providing a static framework for inventory replenishment (Sani et al., 2017). For instance, in a scenario with monthly demand of 1,000 units, a changeover cost of $500, and an inventory carrying cost of 30%, the EOQ computes to approximately 578 units, which balances ordering and holding costs efficiently under stable demand conditions.

Conversely, demand-based or synchronous manufacturing models are more responsive and are designed to align production closely with real-time customer demand. This approach minimizes excess inventory by producing only what is necessary and when it is needed. The EOQ calculation here uses a simplified formula that emphasizes responsiveness, reducing lead times and promoting lean operations (Rezaee & Elmore, 1997). The same demand scenario yields a smaller EOQ of about 82 units, reflecting the leaner inventory requirements and the emphasis on flexibility and rapid response.

The shift from traditional to demand-based EOQ models has significant implications for ROI and operational agility. The demand-based approach typically results in lower inventory costs, lower capital tied up in stock, and reduced waste due to obsolete or excess inventory. In industries with highly variable demand or rapid product life cycles, responsiveness and agility can be competitive differentiators (Coyle et al., 2016). Furthermore, reduced inventory levels lead to decreased storage costs, improved cash flow, and enhanced ability to adapt swiftly to market changes.

However, transitioning to a demand-based model requires robust information systems and real-time data sharing across supply chain partners to predict customer needs accurately. This higher reliance on technology and collaboration adds complexity but pays off through increased supply chain resilience. Companies embracing synchronized manufacturing often adopt just-in-time (JIT) principles, reducing buffer stocks and emphasizing quality and process improvement (Milosz, 2012). It’s vital that organizations cultivate a culture of continuous improvement and invest in supply chain transparency to realize maximum benefits from demand-driven inventory management.

From a financial perspective, adopting demand-based EOQ methods improves working capital management by reducing inventory holding costs and minimizing obsolescence risks. In financial terms, this results in better ROI, higher asset turnover, and more flexible operational capabilities (Sanjay, 2017). Moreover, this approach aligns manufacturing output more closely with actual customer orders, leading to increased customer satisfaction due to shorter lead times and improved delivery reliability (Jennifer, 2004).

Nevertheless, organizations must carefully assess their operational environment, complexity levels, and technological readiness before shifting to demand-based models. Industries with stable demand patterns or long lead times may find traditional EOQ sufficient, while high-variability sectors such as fashion or electronics benefit more from synchronized, demand-driven strategies (Milosz, 2012). Ultimately, a hybrid approach that combines forecast-driven planning with real-time responsiveness may serve organizations seeking to balance efficiency and flexibility.

In conclusion, transitioning from traditional EOQ to demand-based, synchronous manufacturing offers substantial financial and strategic advantages. By reducing inventory levels, lowering costs, and enhancing responsiveness, firms can improve ROI and maintain competitive edge. Success depends on technological infrastructure, supply chain collaboration, and organizational culture. Companies must evaluate their unique operational context to determine the most suitable approach that supports long-term growth and agility.
