Abstract
Based on previous reports on designing buffer capacity, the mixed-model assembly line is classified into two types, that is, Model I and Model II. For these models, relations which illustrate the value of the work zone (for Model I) or the latest work end point (for Model II) at each station are considered. Using these relations, equations which represent the value of the work allowance at each station and the maximum work congestion at the assembly line are formulated for each model. Also relations between the cycle time of conveyer line and the work allowance or the overtime work are specifid.
