Sistem Logistik Pelabuhan - Minggu 6a-1 - Pola pasokan bagian pertama

Summary

The lecture discusses supply chain patterns focusing on maritime logistics. It covers the dynamics between ports and their hinterlands, emphasizing supply availability, vessel selection, and cost considerations. Key points include determining supply patterns based on demand, selecting parcel sizes, and choosing appropriate ship types. The lecture highlights the importance of technical aspects, like draft compatibility, storage capacities, and operational efficiency, in decision-making. It further delves into the continuous or discrete nature of demand, supply availability at different points, and the overall impact on logistics operations. The session underscores the need for a strategic approach in planning supply routes and vessel utilization to optimize costs and meet demand effectively.

Takeaways

• 📦 Supply and demand management is crucial in transportation logistics, specifically in managing port operations and shipment schedules.
• 🚢 Key decisions include determining parcel size for shipping and the type of vessel used based on availability and cost efficiency.
• 🛳️ The shipping method depends on factors such as ship availability, ship size, depth of the docking area, and potential risks like water level changes.
• 📊 Supply analysis involves balancing demand throughout the year, with considerations for continuous vs. discrete demand patterns, such as daily fuel needs vs. industrial demands.
• ⚖️ Supply capability is matched with demand, ensuring available supply sources (like refineries) meet the demand levels for a specific location.
• 🏗️ Technical constraints such as storage tank capacity and terminal operations must align with parcel size to prevent logistical issues.
• 🔄 Vessel scheduling and call frequency are calculated based on parcel size, demand, and unloading time, ensuring efficiency in unloading operations.
• 💼 Economic factors, including operational costs, should be considered when choosing supply patterns to maintain cost-effectiveness.
• 🔍 New supply patterns can be proposed based on changes in distances, shipping points, and ship types, with a focus on optimizing routes and minimizing costs.
• 🛠️ Analyzing logistics chains involves mapping out supply sources, shipping methods, and terminal capacities to ensure smooth and efficient operations.

Q & A

What is the primary topic discussed in this lecture segment?

The lecture focuses on supply chain patterns, particularly concerning the logistics of shipping and the factors influencing supply and demand within a transportation network.

What is meant by 'parcel size' in the context of this lecture?

'Parcel size' refers to the size or quantity of goods being shipped in each delivery. It directly influences the number of ship arrivals and the overall logistics strategy.

What are the two key decisions involved in determining the supply pattern?

The two main decisions are the size of the shipment ('parcel size') and the type of ship that will be used for transporting the goods.

How does ship availability affect supply chain decisions?

Ship availability is critical because different ships have varying capacities. The decision to use a particular ship depends on whether it's suitable for the volume of cargo, the route, and the specific conditions of the port.

What are the risks associated with using ships that have different draft levels in shallow waters?

Ships with deeper drafts may encounter issues in shallow waters, especially during low tides. If the ship’s draft exceeds the depth of the river or sea, it may not be able to dock or move efficiently.

How does demand continuity impact the supply chain?

If demand is continuous, like the need for fuel in daily operations, shipments will occur regularly. However, if demand is sporadic, such as for industrial purposes, shipments may only happen periodically, which requires different supply chain planning.

What is the importance of matching shipment size with storage capacity?

Matching shipment size with storage capacity is crucial to avoid overfilling. For example, if a storage tank can only hold 10,000 KL, sending a ship carrying 15,000 KL would be inefficient, as the excess would have no place to be stored.

What are the two key factors influencing port operation costs?

The two key cost factors are the setup time of the ship and the time taken for loading and unloading cargo, which includes the efficiency of equipment at the port.

What should be considered when creating a new supply pattern?

When creating a new supply pattern, considerations include the type of ship, the distance to the destination, and whether existing supply points can handle the volume or whether new sources are needed.

Why is it important to understand the characteristics of both supply and demand in logistics planning?

Understanding the characteristics of supply and demand helps in making informed decisions about shipment frequency, the types of ships needed, and optimizing the costs and efficiency of the supply chain. It also helps in aggregating supply and demand over time for better resource planning.
