We consider the scheduling problem of minimizing the average-weighted completion time on identical parallel machines when jobs are arriving over time. For both the preemptive and the nonpreemptive setting, we show that straightforward extensions of Smith's ratio rule yield smaller competitive...

intensely challenges real time adaptive production scheduling and control. Indeed, many of the most popular heuristics continue … to use Johnson’s algorithm (1954) as their core. This paper presents a state space (SS) heuristic, integrated with a … closed-loop feedback control structure, to achieve adaptive production scheduling and control in OKP. Our SS heuristic …
