The impact of alternate periods of learning and forgetting on product
quality in a manufacturing system is discussed in this paper. Factors
that may precipitate forgetting are often recognized as interruptions
in the production process. Interruptions can occur at scheduled times
or randomly. The approach presented here addresses the mixed effect of
learning and forgetting. The resultant output of the worker is compar
ed with the expected output without interruption. A case model is used
as an illustrative model for the proposed methodology. The approach e
xtends the conventional univariate learning curve to a multivariate mo
del and incorporates a forget model. Multivariate analysis facilitates
the inclusion of other important factors in manufacturing productivit
y analysis. The inclusion of a forget model creates a realistic repres
entation of the effects of learning and forgetting on worker output an
d product quality.
