Sequence inlining system

from Wikipedia, the free encyclopedia

The term sequence inlining system as a system of sequenced delivery is used in two different meanings, as a general designation for an IT system and as a designation of an organizational principle, but these consider the same topic in terms of content.

Areas of application for a sequence inlining system as an information and control system as well as an organizational principle can be found in particular in the automotive and supplier industry, where a large number of variants of the modules to be installed must be provided with the just-in-sequence principle (e.g. E.g. seats in the right color, the right gearbox variant, ...).

IT system

A sequence inlining system as an IT system controls the sequential delivery of parts and assemblies to the production line .

The system takes into account in a preview at what point in time the appropriate variant of a part ordered by the customer must be made available at the installation location through the specified production program. In the calculation of the sequence chain, taking into account all the time requirements in the process chain, the system informs the supplier or the logistics department when the delivery, in extreme cases even the assembly of the part, is to begin.

The sequence inlining system is used in practice, particularly in the automotive industry, which works heavily with sequential deliveries, as a link to various other IT systems (assembly planning system, warehouse management system, transport control system, etc.).

Since in the majority of cases very strong adjustments to the existing IT environment are necessary, a sequence inlining system cannot be referred to as standard software . As a result, the actual practical name of the system is very different.

Organizational principle

As an organizational principle, the sequence inlining system describes the entirety of the organizational measures that are required to support the internal material flow of a production or assembly process in such a way that the final production or assembly sequence is available through the right part at the right time and at the right place . In automotive engineering, one speaks of a “pearl necklace”. In addition to the pure personnel organization, the organizational measures also include personnel deployment control, transport and means of transport planning and material inventory control.

In the case of complex production structures such as in automobile construction, in which a product passes through different production areas, the original production sequence can be destroyed, which is often caused by quality problems with the necessary rework . A sequence judge is required to restore the original or planned sequence. This can be, for example, a sorting store or also parallel material flow paths that are connected with switches.
