EOQ Calculator

EOQ Calculator







Please note that this is a simple implementation and might not cover all aspects of your specific use case. You might need to adjust it according to your needs. Also, remember to handle potential division by zero errors when implementing this in a production environment.

The goal of EOQ is to determine the optimal order quantity and time intervals of ordering in order to reduce costs, such as inventory carrying and ordering costs, while still having the necessary level of stock available.  Understanding and applying EOQ is essential for effectively managing inventory levels, understanding the economic implications of ordering decisions, and forming long-term strategies for operating a business.

As EOQ faces many shortcomings, other models are  used in its’ place.

Simple Bull-Whip calculator

Please enter your demand and order data as comma-separated values. Then click 'Calculate' to see the Bullwhip Effect.

The bullwhip effect is calculated as the ratio of the variance of orders to the variance of demand. Here’s what different values might imply:

  • Bullwhip effect > 1: This means that the variance of your orders is greater than the variance of your demand. This could be a sign that your supply chain is experiencing significant fluctuations in orders due to changes in demand. This might lead to inefficiencies such as excess inventory or stockouts.

  • Bullwhip effect = 1: This means that the variance of your orders is equal to the variance of your demand. Your supply chain is responding proportionally to changes in demand.

  • 0 < Bullwhip effect < 1: This means that the variance of your orders is less than the variance of your demand. Your supply chain might be more stable and less affected by fluctuations in demand. However, it could also mean that you’re not responding adequately to changes in demand, which could lead to issues like stockouts or excess inventory.

  • Bullwhip effect = 0: This would mean that there is no variance in your orders, regardless of the demand. This is highly unlikely in a real-world scenario.

Remember, these are just general interpretations. The specific implications can vary depending on the context and specifics of your supply chain. It’s always a good idea to delve deeper into your supply chain processes if you notice extreme bullwhip effect values.

Demand Forecasting Tool

This tool will help you to calculate the forecast for future periods based on the sales data from five periods.











This tool can be used to predict future demand for a product based on historical sales data. While it won’t be as sophisticated as professional demand forecasting software, it can provide a basic understanding of how demand forecasting works.

Product Stage Tracker

Product Tracking

Product Stages

Update Product Stage

This tool provides a visual representation of a product’s progress through different stages in a supply chain, with an option for manual updates. It’s a simplified example and doesn’t include features you might need in a real-world application, like integration with a database or error handling for invalid inputs. But it gives you an idea of how you could use HTML, CSS, and JavaScript to track and display product stages in real-tim

Interactive Scatter Plot Generator



This code is designed to take a series of data points in the format {"ds": 10, "y": 20} and plot them on a chart using D3.js. The ds value represents the x-coordinate and the y value represents the y-coordinate of each point.

To add data to this code, you would enter it into the text area in the format specified above. Each data point should be separated by a comma. Here’s an example:

{"ds": 10, "y": 20}, {"ds": 20, "y": 40}, {"ds": 30, "y": 60}, {"ds": 40, "y": 80}

After entering your data, click the “Submit” button. The code will then parse your data, calculate the scales for the x and y coordinates based on the maximum values in your data, and plot each point on a chart.

Please note that this is a very basic example and doesn’t include many features you might need in a real-world application, such as error handling for invalid inputs or interactive features like zooming and panning. However, it gives you an idea of how you can use D3.js to create a simple scatter plot from user input.

The “Interactive Scatter Plot Generator” can be quite important in supply chain management for several reasons:

  1. Data Visualization: Supply chains generate a lot of data, from inventory levels to delivery times. Visualizing this data can make it easier to understand and interpret, leading to better decision-making.

  2. Trend Identification: Scatter plots can help identify trends or patterns in the data, such as seasonal fluctuations in demand or correlations between different variables.

  3. Anomaly Detection: Visualizing data can also help identify anomalies or outliers, such as unexpected spikes in demand or unusually long delivery times. These could indicate problems that need to be addressed.

  4. Interactive Analysis: The interactive nature of the tool allows users to input their own data, making it a flexible solution for analyzing different datasets.

  5. Communication: Visual representations of data can be more effective for communicating findings to stakeholders who may not have a technical background.

In summary, an interactive scatter plot generator can be a valuable tool for analyzing and understanding the vast amounts of data generated in supply chain management.

Sustainability Calculator

Sustainability Calculator

Sustainability Calculator











It’s a simple web page that allows users to input data about their supply chain and calculates some basic sustainability metrics. Here’s how it works:

  1. The HTML structure includes a form for users to input data about their total production, waste, carbon emissions, energy usage, and water usage.

  2. When the form is submitted, the page doesn’t reload (which is the default behavior of HTML forms). Instead, it retrieves the data from the form.

  3. It then calculates four sustainability metrics:

    • Waste Efficiency: This is calculated as (1 - waste / total production) * 100. It represents the percentage of production that is not wasted.
    • Carbon Efficiency: This is calculated as (1 - carbon emissions / total production) * 100. It represents the percentage of production that does not result in carbon emissions.
    • Energy Efficiency: This is calculated as (1 - energy usage / total production) * 100. It represents the percentage of production that does not consume energy.
    • Water Efficiency: This is calculated as (1 - water usage / total production) * 100. It represents the percentage of production that does not consume water.

  4. The results are then displayed on the web page.

In terms of its importance for supply chain management:

  • Sustainability Metrics: The tool calculates key sustainability metrics which can help a company understand its environmental impact and identify areas for improvement.

  • Resource Optimization: By tracking waste, carbon emissions, energy usage, and water usage, companies can identify inefficiencies in their supply chain and take steps to optimize resource use.

  • Regulatory Compliance: Many jurisdictions require companies to track and report on their environmental impact. This tool could aid in that process.

  • Brand Reputation: Consumers are increasingly concerned about the environmental impact of the products they buy. Companies that can demonstrate a commitment to sustainability may have a competitive advantage.

Remember, this is a simple example and a real-world tool would likely need to be much more complex. For example, it might need to pull data from a database or an API, handle more sophisticated calculations, or present the data in a more visually appealing way.

Trailer Carbon Emission Calculator

Trailer Carbon Emission Calculator

Trailer Carbon Emission Calculator







Carbon Emissions:

This tool allows users to input data about their trailers and calculates the carbon emissions based on the distance and fuel efficiency. Here’s how it works:

  1. The HTML structure includes a form for users to input data about their trailer name, distance traveled, and fuel efficiency.

  2. When the “Add Trailer” button is clicked, it prevents the page from reloading (which is the default behavior of HTML forms). Instead, it retrieves the data from the form.

  3. It then calculates the carbon emissions as distance / fuelEfficiency. This represents the amount of carbon emissions per mile.

  4. The calculated emissions along with the trailer name are then stored in an array of trailers.

  5. The displayTrailers function is called which updates the list of trailers on the web page with their respective carbon emissions.

In terms of its importance for supply chain management:

  • Carbon Footprint: The tool calculates key sustainability metrics which can help a company understand its environmental impact and identify areas for improvement.

  • Resource Optimization: By tracking carbon emissions, companies can identify inefficiencies in their supply chain and take steps to optimize resource use.

  • Regulatory Compliance: Many jurisdictions require companies to track and report on their environmental impact. This tool could aid in that process.

  • Brand Reputation: Consumers are increasingly concerned about the environmental impact of the products they buy. Companies that can demonstrate a commitment to sustainability may have a competitive advantage.
