Learn in the textbookResponding to Demand and Operational Processes
DefinitionDemand management (需要管理) is the activity of understanding and forecasting how much a service will be used (demand) and adjusting things so that it stays in balance with what can be provided.
ExplanationIt records how user numbers change and how usage rises and falls by time of day and season, and uses this to estimate future demand. If demand looks likely to exceed what can be provided, it prompts preparations to add resources, and it may also ask users to avoid peak hours so that the demand side itself is smoothed out.
AnalogyIt is like a power company estimating the summer-afternoon peak in advance and asking customers to save power or shift when they use it, so that the peak comes down.
