Types of Distribution Centres:
There are several types of distribution centres, each with a specific focus or purpose. Some of the most common types of distribution centres include:
- Retail Distribution Centres: Retail distribution centres are responsible for managing the distribution of products to retail stores. They typically handle a large volume of products and are focused on delivering products to stores in a timely and efficient manner. These centres are critical in ensuring that the shelves of retail stores are always stocked with the right products, and that stores are able to meet the demands of their customers.
- Wholesale Distribution Centres: Wholesale distribution centres are responsible for managing the distribution of products to other wholesalers or businesses. They typically handle large quantities of products and are focused on delivering products to other businesses in a timely and efficient manner. These centres are critical in ensuring that businesses are able to source the products they need to operate their own businesses.
- E-commerce Distribution Centres: E-commerce distribution centres are responsible for managing the distribution of products that are purchased online. They are focused on delivering products to the end customer in a timely and efficient manner. These centres are critical in ensuring that online retailers are able to meet the demands of their customers and provide a seamless shopping experience.
- Manufacturing Distribution Centres: Manufacturing distribution centres are responsible for managing the distribution of products that are manufactured on site. They are focused on ensuring that products are available for use in the manufacturing process and are responsible for managing the inventory levels of raw materials and finished products. These centres are critical in ensuring that the manufacturing process runs smoothly and that products are available when needed.
- Cross-Docking Distribution Centres: Cross-docking distribution centres are focused on quickly transferring products from one mode of transportation to another. They are designed to minimize the time that products spend in storage and are focused on ensuring that products are delivered to their final destination as quickly as possible. These centres are critical in ensuring that products are delivered on time and that transportation costs are minimized.
- Temperature-Controlled Distribution Centres: Temperature-controlled distribution centres are designed to store products that require a specific temperature range. They are focused on ensuring that products are stored in a way that maintains their quality and freshness. These centres are critical in ensuring that products like food and pharmaceuticals are delivered to the end customer in a safe and effective manner.
NDC-National Distribution Centre
NDC is a central hub that is used to manage the distribution of products on a national or global scale. It is a large warehouse that is responsible for storing and distributing large volumes of products across different regions or countries. NDCs are often owned and operated by large multinational corporations, and they are used to manage the distribution of a wide range of products, from food and clothing to electronics and appliances.
One of the key benefits of using NDCs is that they can help companies to reduce their overall transportation costs. By consolidating their distribution operations in one central location, companies can optimize their shipping routes and reduce the number of trucks and other vehicles needed to transport their products. Additionally, NDCs can help companies to improve their inventory management by providing a centralized location for storing and tracking their products.
NDCs are typically located in areas with good transportation infrastructure, such as near airports, highways, and seaports. This allows for easy and efficient movement of goods in and out of the centre. The size of an NDC can vary depending on the size of the company and the products being distributed. Some NDCs can be as large as several million square feet, while others can be smaller.
The operations at an NDC are complex and require advanced logistics management systems to ensure the efficient movement of goods. Typically, products are received from manufacturing facilities or suppliers and then sorted, stored, and prepared for distribution to regional distribution centres, retail stores, or directly to customers. This process can involve the use of automated material handling systems, such as conveyors, automated storage and retrieval systems, and robotics.
Another key benefit of using NDCs is that they can help companies to improve their supply chain resilience. By having a centralized location for managing their distribution operations, companies can more easily manage disruptions caused by natural disasters, supply chain disruptions, or other unexpected events. NDCs can also help companies to respond quickly to changing market demands by providing a flexible and scalable distribution network.
In addition to their role in managing the distribution of products, NDCs can also provide value-added services to their customers. For example, some NDCs may offer kitting and assembly services, where products are assembled or packaged according to specific customer requirements. Other value-added services may include labeling, product customization, and reverse logistics, where products are returned and processed for resale or disposal.
RDC- Regional Distribution Centre
RDC or Regional Distribution Centre is a type of distribution centre that is used to manage the distribution of products within a specific geographic region. RDCs are smaller than NDCs and are typically located closer to retail stores or customers to provide faster delivery times. RDCs are also commonly referred to as satellite warehouses, regional warehouses, or local distribution centers.
The primary function of an RDC is to receive, store, and distribute products within a specific region. These products are typically received from NDCs or directly from manufacturers or suppliers. RDCs are responsible for managing inventory levels to ensure that products are available to meet customer demand. They are also responsible for preparing and packaging products for delivery to retail stores or customers.
RDCs can vary in size depending on the size of the company and the volume of products being distributed. Some RDCs can be as small as a few thousand square feet, while others can be larger than 500,000 square feet. The location of an RDC is critical to its success, as it needs to be easily accessible to retail stores or customers within its region.
The operations at an RDC are similar to those at an NDC, but on a smaller scale. Products are received and sorted, and then stored in the warehouse until they are ready to be distributed. RDCs may use automated material handling systems, such as conveyor systems and robotics, to manage the flow of products within the warehouse.
One of the key benefits of using RDCs is that they can help companies to reduce transportation costs and improve delivery times. By having a distribution centre located closer to customers, companies can reduce the distance that products need to travel, thereby reducing transportation costs and improving delivery times. Additionally, RDCs can help companies to improve their inventory management by providing a centralized location for managing inventory levels within a specific region.
Another benefit of using RDCs is that they can help companies to improve their responsiveness to customer demands. By having a distribution centre located closer to customers, companies can respond more quickly to changes in demand, as they can quickly replenish inventory levels at retail stores or directly to customers. This can help companies to improve their customer satisfaction and increase their market share.
In addition to their primary function of managing the distribution of products, RDCs can also provide value-added services to their customers. For example, some RDCs may offer product assembly or customization services, where products are assembled or packaged according to specific customer requirements. Other value-added services may include labeling, product testing, and quality control inspections.
Managing Distribution Centres – NDC V/s RDC
When it comes to managing the distribution of products within a specific geographic region, companies have two main options: using a Single National Distribution Centre (NDC) or Multiple Regional Distribution Centres (RDCs). Both options have their advantages and disadvantages, and the decision on which one to use depends on various factors, including the size of the company, the volume of products being distributed, and the location of customers.
A Single NDC is a centralized distribution centre that manages the distribution of products for the entire country. All products are received, stored, and distributed from this one location. This approach has the advantage of centralizing inventory management and reducing transportation costs. It also allows for better control over inventory levels and can lead to improved product availability.
However, a Single NDC also has some drawbacks. First, it can lead to longer delivery times, as products need to travel longer distances to reach customers. This can be a significant issue for companies that need to deliver products quickly, such as those in the e-commerce industry. Second, a Single NDC can be vulnerable to disruptions, such as natural disasters or labor strikes, which can impact the entire distribution network.
On the other hand, Multiple RDCs are smaller distribution centres that are located closer to customers within a specific geographic region. This approach has the advantage of reducing transportation costs and improving delivery times, as products need to travel shorter distances to reach customers. It also allows for more flexibility in managing inventory levels and can help companies to better respond to changes in customer demand.
However, Multiple RDCs also have some drawbacks. First, they can be more complex to manage than a Single NDC, as inventory levels need to be managed across multiple locations. Second, they can lead to higher operational costs, as multiple distribution centres need to be staffed and maintained.
NDC V/s RDC in terms of distance
In the case of a Single NDC, all products are received, stored, and distributed from one central location. This approach may result in longer distances that products need to travel to reach customers. For example, if the NDC is located on one side of the country and a customer is located on the other side, the product will have to travel a longer distance to reach that customer. As a result, the average kilometer traveled by the product in the distribution network will likely be higher for a Single NDC.
On the other hand, Multiple RDCs are smaller distribution centcenterst are located closer to customers within a specific geographic region. This approach can reduce the distance that products need to travel to reach customers, as products are stored and distributed from regional locations that are closer to customers. For example, if a company has an RDC located in the eastern region of the country and a customer is located in that region, the product will have to travel a shorter distance to reach that customer. As a result, the average kilometer traveled by the product in the distribution network will likely be lower for Multiple RDCs.
In this project
Our client was faced with the decision of whether to improve their delivery centre through the implementation of a single National Distribution Centre (NDC) or multiple Regional Distribution Centres (RDCs). While the NDC option was more cost-effective than having multiple RDCs, it resulted in increased lead times and operational costs, thereby negating some of the advantages gained. Our client was grappling with the question of which option to choose in order to optimize their operational costs, reduce distance travelled, and enhance customer satisfaction by reducing lead times
Data Analysis revealed
A branch network is typically designed based on factors such as the size of the customer network, customer locations, and transportation infrastructure. For example, a company may have several branches located in different regions of a country to efficiently serve the needs of its customers in those regions. However, if the customer network changes or expands, the branch network may no longer be effectively serving the new customer locations. This is when a branch network and customer network mismatch occurs.
To address a branch network and customer network mismatch, companies can take several measures. One approach is to expand the branch network by opening new locations in areas where there are significant numbers of customers. This can reduce transportation costs and improve delivery times, resulting in increased customer satisfaction. However, this approach can be costly and time-consuming.
Another approach is to optimize the existing branch network by adjusting the inventory levels at each branch based on the demand from the customer network. This approach requires accurate demand forecasting and inventory management to ensure that each branch is carrying the right amount of inventory to effectively serve its customers. This approach can be more cost-effective than expanding the branch network, but it requires accurate data and analytics to make informed decisions.
On the case of an NDC, the central location of the distribution centre may not be in close proximity to all customers, resulting in longer lead times and higher transportation costs. This can lead to a mismatch between the branch network and customer network, as the NDC may not be effectively serving all customer locations. To address this, companies may need to consider opening additional branch locations or using alternative transportation methods such as air freight to reduce lead times and transportation costs.
On the other hand, having multiple RDCs can also result in a branch network and customer network mismatch if the distribution centres are not strategically located to effectively serve the customer network. In this case, companies may need to assess their branch network and determine if additional locations are needed to better serve the customer network. They may also need to implement technologies such as route optimization software to ensure that delivery routes are optimized to reduce transportation costs and improve delivery times.
After analyzing the data and considering our recommendations, our client ultimately decided to implement a Multiple RDC strategy. Through the use of advanced warehouse and distribution software, they have been able to effectively manage multiple RDCs without encountering any significant challenges. According to our analysis, there is a clear winner that has the potential to reduce transportation movements by up to 83%.
(insert circle graph of 83% reduction in cost of transportation)
As a result, our project objectives, which included reducing lead times, increasing customer satisfaction, lowering transportation costs, and improving overall operations, have all been achieved.
Distribution centres play a crucial role in supply chain management by serving as the backbone of the transportation and distribution network. They serve as the primary hubs for managing inventory and facilitating the movement of goods between manufacturers, retailers, and end customers.
When deciding on the type of distribution centre to implement, companies must weigh the benefits and drawbacks of options such as National Distribution Centres (NDCs) and Regional Distribution Centres (RDCs). While an NDC may offer cost savings, it may not be able to effectively serve all customer locations due to a branch network and customer network mismatch. On the other hand, implementing multiple RDCs may be more effective in serving the customer network, but can lead to higher operational costs.
It is important for companies to regularly assess their distribution network and implement advanced warehouse and distribution software to optimize operations, reduce transportation costs, and improve customer satisfaction. Companies must also take into consideration the impact of branch network and customer network mismatches and take steps to address them.
Ultimately, the success of a distribution centre strategy depends on a variety of factors, including the nature of the product being distributed, the customer demand, and the supply chain network. By carefully evaluating these factors and making informed decisions about their distribution centre strategy, companies can achieve their operational and financial goals while providing high-quality service to their customers.
