Summary. This paper considers the matter of minimizing the agenda size of a two-machine store during which notonly can a role be assigned any of the 2 attainable routes, but additionally the processing instances depend upon the selected route.This challenge is understood to be NP-hard. We describe an easy approximation set of rules that promises a worst-caseperformance ratio of two. We additionally current a few variations to this set of rules that enhance its functionality andguarantee a worst-case functionality ratio of 3=2.

Assemble the clamp lock mechanism as shown in figure 94 by first attaching one end of each hinge to the end of each side rail on the upper clamp frame with #8 x 1" machine screws & nuts. Then attach the other end of each hinge to the clamp lock bars using #8 x 1" machine screws with nuts. Next insert the lock handle through the 112" diameter holes in the bottom end of the lock bars.
