Abstract
Mixed Model Assembly Line are widely used to produce different models as per
customer's demands. sequencing problem is an important factor for an efficient use of
Mixed Model Assembly Line. The Sequencing Problem is resolved in favor of
minimzing the total cost and to keep uniform usage of each part.
In this research project cost model is presented. To get merits and demerits
between Mixed Model Assembly Line and Flexible Assembly Line, a comparision is
done concerning sequencing problem with cost saving and to keep continue usage of
each part. Previously, researchers worked to minimize the utility time or setup time
within Mixed Model Assembly Line. But in this research, different models are produced
withing Mixed Model Assembly Line and without setup and then Mixed Model
Assembly Line is compared with Flexible Assembly Line, where setup is required.
Hence, this research is new and has its novelty. To measure the performance of Mixed
Model Assembly Line and Flexible Assembly Line, different parameters i.e. different
sequence patterns, constant and random demand, cycle time and setup time are used
to check effect on total cost per unit is computed. This analysis yields a comprehensive
result in favor of Mixed Model Assembly Line to save the cost. The outcome of this
research suggests about best sequence pattern for Mixed Model Assmebly Line and
Flexible Assembly Line, which gives continue consumption of each part and cost
saving and reducing of cycle time, would provide higher production.
