Manufacturing Progress Functions I. An Alternative Model and Its Comparison With Existing Functions

SUMMARY Studies performed over a period of eight years have confirmed that the model ∑.y+ C = a (∑ x)m, derived for the learning of individuals, applies to learning of all kinds in industry. In this paper the model is discussed and its application compared with existing theories. In general, the aim has been not so much to derive a mathematical function, as lo find a model capable of simple graphical interpretation which may be used in training and production scheduling at shop floor level.
