Frequency

Frequency in foreign trade usually refers to the number of departures/sailings/flights of a transport vehicle (such as a ship, flight, or truck) on a specific route or leg, or the rate at which business activities such as orders, inquiries, or complaints occur. Usage scenarios include: 1) Logistics arrangements, e.g., 'This route has three sailings per week, a high frequency'; 2) Customer communication, e.g., 'The frequency of customer inquiries has increased'; 3) Production scheduling, e.g., 'Delivery frequency must match the production rhythm.' Notes: High or low frequency directly affects inventory costs, capital occupation, and delivery flexibility; it differs from 'Schedule,' which emphasizes fixed timetables, while frequency emphasizes the number of times; it differs from 'Density,' which focuses on quantity per unit space or time, while frequency focuses on time intervals. Distinction: Frequency is a repetition indicator in the time dimension, whereas 'Capacity' is a carrying capability in the spatial dimension. Practitioners need to assess logistics timeliness, negotiate delivery terms, and optimize supply chain responsiveness based on frequency.
