Nábehu

Nábehu is a Czech noun that denotes the process of starting up or ramping up toward a steady state. It is used in several fields to describe a gradual transition from initial conditions to normal operating conditions. The form náběhu is the genitive singular, commonly appearing in phrases such as “dlouhý náběh” or “po náběhu zátěže.”

Etymology and meaning

Náběh comes from the verb běžet (to run) with the prefix ná-, combined with the noun běh (a run or period of running). The term is closely tied to the idea of progression or adaptation over time, rather than an abrupt switch from off to on.

Typical contexts

- Mechanical engineering and manufacturing: the bedding-in or break-in period of a new machine or engine, during which components wear in and operating conditions are gradually increased. Guidelines emphasize slow acceleration, monitoring temperatures, and avoiding heavy loads until wear-in criteria are met.

- Production and process engineering: ramp-up of a production line to reach full capacity, including gradual increases in throughput, energy use, and staffing.

- Information technology and systems: the initial startup or warm-up phase of a system or server, when caches are populated and performance stabilizes.

- Economics and product management: introduction phase of a product or service, where demand and supply are brought to target levels.
