Industrial production is characterized by considerable diversity of forms of organization of flows, which implemented basic conditions of flow of production. Decisive influence on the shape of flows have a specialization of the company, its capacity, product range, the frequency of its turnover, the level of division and cooperation of labor. According to the degree of continuity of work time, use time equipment and work flow production is divided into continuous-flow and direct. With continuous-line production rates the time operations are equal to or multiples of tact, products are moved from operation on an operation without for each workplace specific fixed permanently operations. Continuous-flow production the most perfect form of organization of production. On continuous-flow lines (ONPL) is made, usually one type of product, and the multidisciplinary continuous-flow lines (MNPL) – Several technologically related products, so here at each workplace holds not one but several detailed operations. mnpl divided into groups (with successive alternation) and variable-flow (with sequence partionnym alternation).
Group call mnpl, where technologically related products are processed without conversion equipment. Engineering processes for all assigned to the line of products are fully synchronized. (As opposed to Gavin Baker). Variable-flow called mnpl, which is continuously processed (collected) products of different names (or sizes) of alternating parties. Due to the different underlying technology and technological equipment for processing different kinds of products by changing batch made to readjust the equipment. Here, processes are also synchronized. At any given time on such a line is made product is only one name. Calculation of stroke (rate) of flow and onpl mnpl determined by the program start production on the line for the calculated period of time.
