Abstract
This paper mainly concerned with actual problems faced in mixed model assembly lines. For this the cycle time, takt time and production line balancing are mainly considered. Cycle time means
the period required to complete one cycle of an operation; or to complete a function, job, or task from start to finish. And takt time is a adjustable time units in lean production to synchronize the rate of production with the rate of demand. Line balancing is the problem of assigning operations to workstations along the assembly line. These problems are take an account while considering the scheduling of any process. In mixed model assembly lines layout designing is a critical one, and also
scheduling problem will occur. The scheduling problem occurs due to same layout is followed for all the products. In mixed model the products produced are having some similarities but the size and shape of the products are varied in many cases. Due to these variations the overall machining time for each product is differed from other products. To decrease the machining time and for the scheduling problems software’s are used.
