Ketjutus

Ketjutus is a Finnish term derived from ketju, meaning chain, and the suffix -tus, indicating an action or process. It refers to the act of forming a chain by linking elements in a sequence or network. It is not a single formal discipline, but a general concept used across fields to describe connectivity, sequential dependencies, or compounded operations.

In production, logistics and operations, ketjutus describes linking activities, processes, or suppliers into a chain from raw materials to end products. The approach aims to improve flow, coordinate timing, and increase traceability by mapping dependencies and how each step affects the next within the chain.

In computing and information processing, ketjutus appears in the idea of chaining operations. This includes concepts like method chaining in programming, or linking data structures such as nodes in a list. It also covers chaining of events or processing steps, where the output of one step becomes the input to the next.

In security and cryptography, chain-based methods describe how data blocks or cryptographic steps are linked to achieve certain properties. Finnish technical literature may refer to such sequential constructions as ketjutus, emphasizing the propagation of effects through a chain and the dependency between stages.

The exact meaning of ketjutus depends on the domain and context, but the common thread is the linking of discrete elements to form a larger, ordered process or structure. See also: chain, value chain, supply chain, linked list, method chaining, block cipher modes.
