DECISION MAKING OF HAND TRACTOR GEAR BOX DESIGNS
ABSTRACT: Decision making on
selection of hand tractor Gear Transmission Box (GTB) “Improvement Designs” is
carried out according to many criteria. Based on the focus group discussion and
brainstorm performed by product-development teams, eight criteria are finally
identified as follows; material corrosion resistance, manufacturability, the
ability of the design to withstand the maximum load operation, material
availability in market, influence on the other components process,
manufacturing cost, mass of GTB design, and processing time. Those criteria are
categorized into positive and negative characteristics. Positive criteria indicate
that score which is the greater the better, by contrast, negative is the less
the better. There are 3 alternatives namely Initial Design, Design 1 and Design
2. The selection is performed based on Analytic Hierarchy Process (AHP) Method.
The evaluation is analyzed separately according to each category. The best
alternative is the one which has the highest ratio between positive and
negative criteria.
