| # Mixed model flow (MIX) An infinite number of product variants can be produced in a mixed model flow, even if no regular demand pattern exists. The products are produced on an assembly line. Material supply must be synchronized with the sequence in which the items are produced. In the mixed model situation, assembly orders are used. An assembly order usually applies to a quantity of one. Production scheduling coordinates the sequence in which orders are put on the lines. Kanbans are common here, as well as sequenced shipment schedules. In a mixed-model flow environment, an order is usually made up of one product, with no two products being the same. Production tasks are determined based on the required product options. This assembly situation is characterized by a high volume production of complex customer-specific products. The manufactured products are mainly product variants and, in a few exceptional cases, some customizations are required. Although the product variants can have different routings, most of the operations are the same, which enables inline production. The focus is on lowering component stock and reducing production and purchase lead times. |
