Food supply chain optimization using PredictHQ intelligent event data from AWS Data Exchange for demand forecasting

The U.S. Department of Agriculture (USDA) estimates that 31% of food loss occurs at the retail/consumer level.  According to the USDA food waste impacts food security, wastage of agricultural resources, and can contribute to greenhouse gas emissions in landfills. This is in addition to the financial cost that businesses incur from inaccurate supply planning. Accurately forecasting customer demand offers an opportunity to optimize supply chains and potentially prevent waste across an organization. It’s also a chance to contribute to improving an organization’s environmental impact and their pursuit of sustainability goals.

PredictHQ data, available for trial and purchase through AWS Data Exchange, provides intelligent event data that reveals the context of how and why demand fluctuates. This helps enables businesses to make data-driven decisions to improve demand forecasting and subsequent supply decisions. Quick- service restaurants, delivery services, supermarkets, and many other types of businesses use PredictHQ to help improve the accuracy of demand forecasting and planning, including inventory and staffing optimizations. Events such as sports games, concerts, and even school and public holidays can have a major impact on demand. For example, store locations for one national fast-food chain saw an 90% increase of in-store demand on Super Bowl Sunday, while another leader in the fast-casual space saw the exact opposite with a 30% drop of in-store demand. By incorporating event data to better predict demand, organizations can help ensure they are optimizing their supply chain and avoiding wastage. Another example is with a leading national fast-casual restaurant chain that, by using PredictHQ’ s intelligent event data API, was able to help improve the accuracy of their demand forecasting. PredictHQ noted they saw $2.7 million in supply chain gains from improving over and under forecasting. In combination with AWS machine learning services, PredictHQ helps organizations to forecast demand, optimize their supply chain and prevent waste.

In this post, we will show how it may be possible to avoid wastage and better forecast food needs using PredictHQ’s dataset with  Amazon Forecast and other machine learning services.

Solution overview

In this use case, we will show how to build a solution for a fictitious restaurant chain called Yummy Burger Co operating outlets across several locations within a city. Its individual outlets run the Point of Sale (POS) application TouchBistro, inventory management for both ingredients and sellable food items on Oracle Retail, and store analytics such as total sales and sales patterns on Oracle. The restaurant owner uses Oracle Fusion Applications for enterprise resource planning (ERP) and Oracle Customer Relationship Management (CRM) system. There are also third parties involved, such as food ingredients suppliers and delivery vendors.

Yummy Burger Co currently uses manual forecasting with statistical Excel-based formulas to analyze its data sets at different scales. These ad hoc methods may produce unreliable results, causing an increase in wastage as food ingredients are procured based on inaccurate predictions of upcoming demand. Using PredictHQ intelligent event data to increase the accuracy of forecasting, Yummy Burger Co will incorporate several broad data types alongside PredictHQ intelligent event data:

  1. Store Applications data – These are mostly custom applications running on relational databases like Oracle, MySQL.
  2. Corporate Data – Oracle Fusion Applications (ERP), Oracle CRM application shared across stores or outlets as SaaS versions.
  3. Third Party Data – Supplier systems, delivery and logistics vendor systems.
  4. PredictHQ Data – Intelligent event data available through AWS Data Exchange for APIs.

To implement this solution, Yummy Burger Co follows these four overall steps:

  1. Data Extraction – Extracting data from these four source systems through an automated data ingestion pipeline by ingesting data into inbound Amazon Simple Storage Service (S3).
  2. Data Unification and Harmonization – Keeping the source data refreshed by harmonizing and unifying the data.
  3. Core Forecasting Engine – Preparing input data for forecasting through Amazon Forecast, invoking Amazon Forecast APIs through Amazon SageMaker Canvas.
  4. Data Visualization – Custom dashboards built using Amazon QuickSight to display forecast outputs. Amazon QuickSight will keep refreshing the dashboards using newly exported forecast results for users to review and make subsequent organizational actions based on the forecasted results.

Solution walkthrough: Using AWS Data Exchange data in demand forecasting

A. Building an automated data extraction pipeline to move input data into Amazon S3

To build an automated data extraction pipeline, follow these steps:

  1. Set up and schedule Database Migration Service (DMS) to migrate your store applications data into an inbound Amazon S3. For example, for Yummy Burger Co to migrate its on-premises Oracle data sources, it did the following:
  1. To connect with Oracle Fusion Application (ERP SaaS), Oracle CRM (SaaS) to extract data into inbound Amazon S3, you must set up and connect your data sources with Amazon AppFlow. To do that:
  1. AWS Transfer Family is a secure transfer service that enables you to transfer files into and out of AWS storage services. To set up AWS Transfer Family services, do the following:
  1. Invoke AWS Data Exchange for APIs to extract PredictHQ data into the common inbound Amazon S3. To do that, follow this tutorial Subscribe to AWS Data Exchange for APIs (Test Product) on AWS Data Exchange. PredictHQ provides further details on their API parameters here.

The following diagram shows steps A1-4.

B. Joining datasets and creating a predictive ML model for forecasting

To harmonize and unify your data sources into a more accurate forecasting tool, do the following:

  1. Join your datasets and create a predictive ML model
  • In the AWS Management Console search field, enter Amazon SageMaker. In the top left corner, choose Canvas. Create a new user profile. To open the Amazon SageMaker Canvas console, choose Open Canvas.
  • In the SageMaker Canvas console, chose Datasets and then Create a new dataset. For the data source, choose Amazon S3. Point to the inbound S3 buckets as your source data. This is the same bucket you point to in step A.
  • To create a consolidated data source by joining four distinct data types using referential keys, choose Join Data. To import data into SageMaker Canvas, choose Import Data.
  • Choose My Models and then choose New Model. Enter a model name. As the problem type, select Predictive Analysis.
  • Select the newly created consolidated data set from above as the input data set of the model. As the target column for forecast output, select future demand. The Model type should automatically point as Time Series. You can optionally configure the model further to define your input parameters.
  • To build the model, choose Quick Build. This will take some time, depending on the size of your input dataset. You can now use your new ML model to analyze your dataset and to generate forecasted demand.
  1. Automate the process for ongoing predictive ML forecasting. To automate the process as datasets update, do the following:

The process is depicted in the figure below as the core engine of your forecasting process.

This image depicts the core engine of your forecasting process. This includes AWS Glue, Amazon Redshift, Raw Data, High Quality Harmonized & Unified Data and Processed Data in one section. There is a multi-direction arrow pointing to another section. This section has Amazon Forecast and Amazon Sagemaker Canvas. There is a multi direction arrow between the two. A image of a person with "Data Scientist" is next to this section.

C. Data visualization and adjusting inventory levels as needed to optimize perishable stock levels

Now that your predictive ML model is created and you have joined your datasets, you can create dashboards for ongoing data analysis and forecasting. To do that, follow these steps:

  1. In the AWS Management Console search field, enter QuickSight.
  2. In the the Amazon QuickSight console window, choose New Analysis. To create custom dashboards, select the outbound S3 you created in step B.2. as your data source.
  3. To set up AWS Glue to automatically trigger a crawler on the exported forecast results into outbound Amazon S3, follow this tutorial Starting jobs and crawlers using triggers. Amazon QuickSight will then automatically refresh the dashboards using newly exported forecast results for users to review and make subsequent organizational actions based on the forecasted results.

Store managers, armed with real-time demand forecasts that incorporate intelligent events from PredictHQ, are now well-prepared for upcoming demand and able to make inventory adjustments to minimize food wastage.

The following is an example of what a store manager might see for one product e.g., bread (Item 39) for their store at one location e.g., Brooklyn (2290). It shows a demand forecast for the next 4 weeks and includes an average as well as upper and lower bounds. With this information, the store manager can make procurement decisions to ensure optimal inventory levels.

This image depicts a chart showing the demand forecasting results. It shows the historical demand for the past 4 weeks and the upper and lower bounds of the forecast for the next 4 weeks. There is an average in-between these for the forward looking forecast.
