物流与冷链
Logistics move goods from producers to users through containers, warehouses, trucks, rail and air freight; the cold chain does the same for food, vaccines and medicines that must stay within a temperature range. Both depend on energy, equipment and labour, and both fail quietly before shortages show. This page sets out how logistics and cold chains work and break, how capacity and integrity are measured, and what evidence serves the operators and agencies responsible.

Logistics and cold chain: how the risk develops.
Transport time and disruption. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Capacity is tightly balanced
Containers, vessels, trucks and warehouse space are run near full use to keep costs low. When demand jumps or capacity is lost, delays and costs rise sharply.
Cold chains need constant power
Refrigerated stores and transport depend on electricity and fuel. Outages and equipment failures expose products to temperatures that reduce quality or make them unsafe.
Labour is a critical link
Drivers, port workers and warehouse staff are often in short supply. Illness, strikes and border rules can stop flows as surely as damaged infrastructure.
Losses show up as shortages
Spoiled food, lost vaccine doses and expired medicines are counted late, if at all. The first visible sign is often a 短缺 at the point of use.

What experts ask about logistics.
- How much spare capacity exists in ports, fleets, warehouses and labour?
- How long can goods wait before they lose value or become unsafe?
- What happens to cold storage and transport when power fails?
- How dependent is the system on digital platforms and data exchange?
- Where do last-mile gaps leave communities without reliable supply?
Why time and temperature matter.
Logistics networks are designed for efficiency, which often means high utilisation and little slack. When demand surges or capacity is lost, queues build quickly: ships wait at anchor, containers pile up and delivery times stretch. Recovery takes time because equipment and crews must be repositioned.
Perishable goods add a hard constraint. Fresh food, vaccines and many medicines must be kept within temperature ranges throughout the journey. A break in the cold chain, from a power outage, a delayed truck or a failed refrigeration unit, can spoil the product. Losses in the cold chain are a significant source of food waste in many regions.
Logistics is increasingly digital. Booking, customs, tracking and payment 系统 are interconnected, so a 网络事件 or system outage at a major operator can halt physical flows.
方法及其局限。
- 01
Operations research models
Queueing, routing and inventory models using 优化与运筹学. They rely on assumptions about behaviour under stress.
- 02
Transport engineering
Assessment of terminal, road and rail capacity using transport engineering.
- 03
Temperature monitoring data
Sensor records from cold-chain shipments. Data are proprietary and not standardised.
- 04
Disruption case studies
Structured analysis of past events. Each event is different, which limits generalisation.
Real operating data are mostly held by private operators, so public analysis often relies on proxies and case studies.
