Multiobjective performances of different integrated strategies under the resource flexibility scenario where
| Integrated strategy | Patient selection rule | Solution | Z | Z1: avg. patient waiting time (min) | Z2: avg. resource overtime (min) | Z3: avg. congestion per time unit | Avg. max. resource overtime (min) |
| (Base scenario) None | FCFS | — | 1408 | 152 | 122 | 78 | 193 | Stage I only | FCFS | Best | 597 | 138 | 44 | 34 | 132 | Stage I + II | FCFS | Best | 508 | 145 | 34 | 37 | 140 | Stage I + II | Eqns. (2) and (3) | First | 449 | 194 | 20 | 118 | 178 | | | Best | 254 | 140 | 9 | 42 | 109 | Stage I + II | CP | First | 606 | 198 | 34 | 127 | 179 | | | Best | 263 | 146 | 9 | 47 | 109 |
