Abstract
By permitting operators to perform a different part of the organization's work, a
cross-training model is developed. Its chief purpose is to promote multi-functionality
of operators thus improves workforce flexibility. This research intends to investigate
the effect of cross-training configurations, focusing on assembly lines under the
influences of operator absenteeism, operator turnover, product changeover and
learning. The cross training configurations, specifically Scheduled Rotation, Floating
Operators, Zoned Worksharing – Two Skills Chaining, Zoned Worksharing –
Hierarchical and Craft were experimented. Productivity, average skill of operators,
average skill deviation within operator, average skill deviation between operators and
the travelling cost incurred were the performance measures employed. An assembly
factory in Prai was used as the case study in which a stochastic production simulation
model was built upon by using WITNESS simulation software integrated with Visual
Basic and Microsoft Access database for data collection. The raw data obtained were
first statistically examined with non-parametric test, and later thoroughly discussed.
As results showed the significant discrepancies of a number of performance
measures on cross training configurations employed, respective classifications were
duly built. The result potentially facilitates the selection of cross training
configurations to meet certain intended performance measures in real industry
applications.
