Effective route planning and scheduling, considering factors such as distance, temperature requirements, and delivery timeframes, are vital to minimize transit time and ensure product integrity upon arrival at the destination.
Differences Between Cold Chain and Normal Supply Chain
Temperature control
The core distinction between cold chain logistics and a normal supply chain lies in temperature control.
Cold logistics focuses on maintaining precise temperature conditions throughout the entire supply chain to preserve the quality, efficacy, and safety of temperature-sensitive goods.
This requires the use of specialized refrigeration systems, insulated packaging, and temperature monitoring devices. In contrast, a normal supply chain does not prioritize temperature control as goods being transported are typically not sensitive to temperature variations.
Perishable goods
Cold chain logistics primarily deals with perishable goods that have a limited shelf life and are highly susceptible to spoilage or degradation if not handled properly. Examples of such goods include fresh produce, dairy products, seafood, pharmaceuticals, and vaccines.
The time-sensitive nature of these goods requires careful handling, storage, and transportation to ensure they maintain their freshness and effectiveness.
In contrast, a normal supply chain may handle non-perishable goods that do not have strict temperature requirements and can withstand various environmental conditions without affecting their quality or safety.
