This paper provides a basis for selecting a system configuration for assembly line operations. Three line systems are considered: single-model line, mixed-model line, and hybrid line. The hybrid line is defined as a line system in which segments of parallel single-model lines are serially connected to segments of mixed-model lines. Total line lengths are analyzed and compared between the three line configurations. It has been shown that the appropriate selection depends on the required quantities and total operation times for each product model. A procedure for selecting an assembly line configuration is presented based on these results.

Key words: mixed-model line, single-model line, hybrid line, line length, throughput time, buffer.
