Summary. This paper considers the matter of minimizing the time table size of a two-machine store during which notonly can a task be assigned any of the 2 attainable routes, but in addition the processing instances rely on 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 increase its functionality andguarantee a worst-case functionality ratio of 3=2.
