Planning for Supply Chain Disruption with DCDR

A Real World Test

Currently, (mid-December 2023) attacks by Houthi rebels on shipping headed towards the Suez Canal are disrupting shipping, and several firms have announced that they will be rerouting vessels via the Cape of Good Hope.

I used this scenario as a real-world test of the DCDR agents to brainstorm the effects this might have on US firms and businesses on the East Coast that rely on imports that transit Suez. Overall, I’m pretty impressed with the results. I’d want to check the details before I made any firm decisions but the general timelines and effects all seem plausible and in the right range.

In essence, this is what I’d expect a junior or mid-level associate to produce in a day or so but the agent did it in ~30 minutes.

Here’s the unabridged conversation. (Note, to avoid duplication, I removed the initial draft of the memo as I changed the request slightly.)

Please don’t use this for planning purposes: this is a proof-of-concept demo only and your situation will be unique to you.

Assistant
 Hi, I'm Bryan, let's start planning for Supply chain disruption. Please give me a little more information on what you are planning for and we can get started.
 
User:
 I need your help to brainstorm the effects of a shipping disruption in the Suez Canal. Houthi rebels in Yemen are interdicting shipping with small boats and also firing missiles at passing ships. Some shipping companies and oil and gas firms are now rerouting vessels via Cape of Good Hope.

I need your help to assess the effects on US East coast firms in general.

First, let's get some basic data points on shipping to the US. How much comes via Suez?


 
Assistant
 According to the United States Census Bureau, in 2020, approximately 9.6% of total US seaborne imports and exports passed through the Suez Canal. To give you an idea, in terms of value, the US imported goods worth $74.5 billion and exported goods worth $31.7 billion via the Suez Canal.

It is important to note that these figures represent the overall trade passing through the canal and not specifically the trade destined for the US East Coast. However, it gives us a rough estimate of the importance of the Suez Canal to US trade.


User:
 Ok. Now if vessels redirect via the Cape of Good Hope, how much additional time does that add for vessels traveling to the US East coast approximately?
 
Assistant
 Redirecting vessels via the Cape of Good Hope instead of the Suez Canal can add significant additional time to their journey. On average, it can add an extra 10-14 days to the voyage. This is due to the longer distance and slower speeds required to sail around the southern tip of Africa.

It's important to note that this estimated additional time can vary depending on factors such as vessel speed, weather conditions, and specific routes taken. However, as a rough estimate, you can consider an additional 10-14 days for vessels traveling from the Suez Canal to the US East Coast if they redirect via the Cape of Good Hope.


 
User:
 Well done. Now, let's think about manufacturers or firms that utilize 'just in time inventory'.

Give me some examples of the timeline or tolerance these supply chains operate on. What are some common 'days of supply' that firms have available?

I'm trying to identify how the additional 10-14 days will affect supply chains that are operating with just in time inventory.
 
Assistant
 Supply chains that operate on a "just-in-time" (JIT) inventory model are designed to minimize inventory holding costs and maximize efficiency by receiving goods and materials shortly before they are needed in the production process. The goal is to have minimal excess inventory and reduce carrying costs.

The specific days of supply that firms operate on can vary depending on the industry, product type, and specific company practices. However, some common examples of days of supply in JIT inventory systems include:

1. Automotive Industry: Just a few hours to a few days of supply for critical components or parts, such as engines or high-demand parts.

2. Electronics Industry: Typically a few days to a couple of weeks of supply for components like semiconductors or specialized components.

3. Fashion Industry: Several weeks to a few months of supply for fashion garments or seasonal products.

In general, JIT inventory systems strive to maintain low inventory levels, often in the range of a few days to a few weeks. This means that any additional 10-14 day delay in shipping can have a significant impact on the availability of goods for these firms. It can result in production disruptions, delays in fulfilling customer orders, and potentially increased costs if alternative supply chain arrangements are required.


 
User:
 Ok, let's build a quick timeline.

Imagine the disruption started on December 15 so any vessels before then are already on their way.

Now, give me a simple bullet point timeline of when the disruptions will be felt for US East coast firms and when the rerouted vessels are estimated to start arriving. Identify any gaps that are going to appear in supply chains.
 
Assistant
 Please note that the timeline provided is an approximation and actual timings may vary based on specific circumstances:

December 15:

- Disruption begins with interdiction of shipping and missile attacks by Houthi rebels in Yemen.

December 15 onwards:

- Vessels already en route to the US East Coast are unaffected by the disruption.

- However, uncertainty and security concerns may cause shipping companies to consider rerouting vessels in the coming days and weeks.

Late December/Early January:

- Shipping companies start rerouting vessels via the Cape of Good Hope as a precautionary measure due to ongoing disruption.

Late January/Early February:

- Vessels rerouted via the Cape of Good Hope begin to arrive on the US East Coast ports.

- However, due to the additional 10-14 days added to the journey, there is a notable delay in vessel arrivals compared to the typical transit time via the Suez Canal.

Late February/March:

- The disruptions are felt by US East coast firms as the delayed vessels start to arrive.

- Just-in-time inventory systems begin to experience gaps in supply chains due to the prolonged transit time.

- Firms relying heavily on goods and materials from disrupted regions may face production disruptions and potential stockouts.

It's important to note that the timeline can be fluid and subject to various factors such as the length of the disruption, availability of alternative shipping routes, and the ability of firms to adjust their supply chains. It's always advisable for firms to closely monitor the situation, communicate with suppliers, and explore alternative strategies to mitigate the impact of disruptions.


 
User:
 Ok, last thing, let's look at alternate supply routes. Currently, the Panama Canal is experiencing limited capacity due to low water levels.

So imagine I am a manufacturer considering getting goods shipped to the US West Coast and then transported cross country.

What would that look like timewise?
 
Assistant
 If you are considering shipping goods to the US West Coast and then transporting them cross country as an alternative to the disrupted Suez Canal route, here's a rough estimate of the timeline involved:

1. Shipping goods to the US West Coast:

- Depending on your location and shipping method, it can take anywhere from a few days to a few weeks for your goods to reach a West Coast port, such as Los Angeles or Long Beach.

- This includes the time for loading, transit, and unloading at the port of origin.

2. Port processing and customs clearance:

- Once your goods arrive at the West Coast port, there will be additional time required for port processing, customs clearance, and possibly inspection. This can typically range from a few days to a week.

 3. Cross-country transportation:

- After clearance, you would need to arrange for land transportation to move your goods from the West Coast to the desired destination on the East Coast.

- The transit time for cross-country transportation can vary based on factors such as distance, route, and mode of transport (e.g., truck, rail).

- On average, it could take around 5-10 days for cross-country transportation, but this can be subject to various factors.

Overall, the total time from shipping goods to the US West Coast to their arrival on the East Coast via cross-country transportation can range from a couple of weeks to a few weeks, depending on various factors such as distance, logistics arrangements, and any potential delays due to congestion or other disruptions along the way.

It's important to note that these timelines are estimates and can be subject to change based on specific circumstances and the prevailing conditions at the ports and transportation infrastructure.


 
User:
 Well done - this is good work. Can you think of any alternate solutions to this problem that could be considered in the short- to mid-term assuming that this issue extends into Q1 of next year?
 
Assistant
 Certainly! Considering the potential extended disruption in the Suez Canal into Q1 of next year, here are a few alternate solutions that could be considered in the short- to mid-term:

1. Utilizing alternative shipping routes:

- Exploring alternative shipping routes, such as routing vessels around the Cape of Good Hope or utilizing the Northern Sea Route (Arctic route) for certain goods, could help mitigate the impact of the Suez Canal disruption.

- However, it's important to assess the feasibility, cost, and environmental impact of these alternative routes, as they may have their own challenges and limitations.

2. Diversifying supply chain sources:

- Actively seeking and diversifying suppliers from different regions could reduce reliance on disrupted areas and provide backup supply options.

- This approach would involve conducting thorough assessments of potential suppliers, assessing their capacity, quality, and lead times, and establishing new business relationships.

3. Implementing buffer inventory and safety stock:

- Increasing buffer inventory or safety stock levels can help offset delays caused by disruptions.

- By holding additional stock, firms can avoid immediate stockouts and maintain production continuity while the disrupted logistics routes stabilize.

4. Leveraging digital technologies and data analytics:

- Implementing digital technologies and data analytics can provide better visibility and real-time monitoring of supply chain operations.

- This can help identify potential disruptions, optimize inventory levels, mitigate risks, and enable quick decision-making to minimize the impact of disruptions.

5. Collaboration and communication within the supply chain:

- Strengthening collaboration and communication with suppliers, logistics providers, and customers can help anticipate and manage potential disruptions proactively.

- Regular communication, information sharing, and contingency planning can help address issues collectively.

These are just a few alternative solutions to consider in the short- to mid-term. The appropriateness and feasibility of each option will depend on individual circumstances, industry dynamics, and the specific requirements of the supply chain. It's always advisable to evaluate the potential impact and risks associated with each solution before implementing them.
 
User:
 Great - some of these are worth exploring later.

For now, please summarize our conversation into a decision-support memo. Outline:

  • The problem

  • The implications

  • The shipping timeline

  • What the alternate west coast supply option looks like.

  • Your additional areas for consideration

 Make the memo clear, comprehensive and format it neatly, ready for issue to decision-makers. Include all pertinent data and any assumptions made.
