Supply Chain Case Studies

SCM Globe comes with a library of case studies that explore commercial, humanitarian, and military supply chains as shown below. The case studies range from relatively simple (Cincinnati Seasonings) to quite challenging (Java Furniture Company, Zara Clothing Company, or Syria Evacuation Scenario). Case studies are laboratories where you apply what you learn in lectures and readings to solve supply chain problems in highly realistic simulations. As you work with case studies you will gain an intuitive sense of supply chain dynamics and develop analytical skills to design and operate real world supply chains (see one instructor’s assessment: What You Learn from Case Studies and Simulations).

The case studies presently available in the SCM Globe library are shown here and you can use any or all of them as you like (you can also create your own case studies). They are listed in the three categories and in approximate order of progressive challenge within each category. We recommend that people new to SCM Globe start with the Cincinnati Seasonings case study. Work through the three challenges presented in the introduction to that case study, and you will learn the skills you need to progress on to more difficult cases. Click on the case studies below to see a description and introduction to each of the cases:

COMMERCIAL SUPPLY CHAINS

DISASTER RESPONSE / HUMANITARIAN SUPPLY CHAINS

MILITARY SUPPLY CHAINS

NOTE: the Syria Evacuation Scenario involves both a civilian humanitarian supply chain and a military supply chain. The humanitarian supply chain is to support the refugees, and the military supply chain supports the military organizations that provide protection for the humanitarian mission.

As shown in the screenshots below, you access the case study library by clicking on the “View Library” button (1) in upper right corner of screen as shown below. In the library you can see a list of supply chain case studies (2) and click the “Import” button to load a selected case study into your account. Then click “My Account” button (3) to go back to your account. In you account screen click the “Edit” button associated with the supply chain you want to work on.

Working with Case Studies

In every case study the goal is first to get the supply chain to run for 15 – 30 days, and then get it to run for that same period of time at the lowest operating cost and lowest on-hand inventory levels across the supply chain. As you figure out how to do this, you will gain an intuitive sense for how supply chains work, and develop your analytical skills for exploring different options.

If you continue with a case study, you will next be challenged to use the understanding and skills you’ve acquired to expand or re-design the supply chain you are working on. If the supply chain is supporting a growing business you need to extend the supply chain to support new stores and still keep operating costs as low as possible. If the supply chain supports a disaster response or humanitarian mission you need to create a supply chain to respond to the disaster and make it run efficiently so that the right aid supplies get to the right places when they are needed.

A popular case study to start with is the Cincinnati Seasonings case study. When you load that supply chain model into your edit screen you will see the beginning supply chain drawn on a map; zoom in and click on products, facilities, vehicles or routes to see information about them.  Then click the “Simulation” button, and a new tab will open in your web browser to run the simulation. Click “Play” to start the simulation. The simulation will cycle through some number of days and then a point of failure in the supply chain will be found – a facility will run out of a product, or a facility will accumulate too much product and run out of storage space to handle it as shown in the screenshot below.

Now you make decisions about how to fix these problems. And you run simulations to see how well your decisions work.

Depending on the changes you make, your supply chain simulation will run for additional days and other problems will arise. Keep improving your supply chain model until you get the simulation to run for 30 days. Then refine your supply chain model to make it run for 30 days using less inventory and with lower transportation and operating costs – that is the challenge in SCM Globe and in real-world supply chains as well.

NOTE: You can run simulations for longer than 30 days, but there is usually little reason to do so. This is because most companies do not run their supply chains unchanged for longer than 30 days at a time. They use a 30 day S&OP (sales and operations planning) cycle and these simulations correspond to that S&OP cycle.

Use Default Values or Research Current Data for Case Studies

When you load any of the case study supply chain models from the SCM Globe library, they come with good default numbers already plugged in. You can either accept the defaults or do some research on the Internet to find more accurate and current data.

Look for data on products, facilities and vehicles that are used in your supply chain and see what their specifications and costs are. Costs can vary widely in different parts of the world. Make your best estimates based on the research and cite the sources of your information.

Metric System of Weights and Measures

In the case studies all weights, volumes, distances and speeds are expressed using the metric system. The metric system is used around the world in every country except three: Liberia; Myanmar; and the United States.

So it is good for supply chain professionals to feel comfortable with the metric system.
