The Mixed Model Learning Curve

Abstract

Abstract In this article an extension of the learning curve concept is introduced by considering the rate of reduction in direct labor assembly time for mixed model assembly situations. Here, more than one model is assembled on the same assembly line; hence, the repetitions of the assembly work are not always the same. Following a short description of the mathematical formulation of the learning curve (for convenience called the single model learning curve), a development of a mixed model learning curve is presented. An example is given to demonstrate the application of mixed model learning.
