Figure 3
The green bars represent “Mould assemble” tasks, and the blue bars represent “Reinforcement bar setting” tasks, as indicated by the legend at the bottom. The legend also specifies “Crew needed: 2” for “Mould assemble” and “Crew needed: 3” for “Reinforcement bar setting,” along with a yellow arrow labeled “Labour flow.” The green “Mould assemble” bars are stacked vertically on the left side of the plot, starting from a low “Time” value. There are four green bars arranged in a step pattern. Following each green bar horizontally, a blue “Reinforcement bar setting” bar is positioned, indicating a sequential task. The blue bars are also stacked vertically in a step pattern and aligned with the corresponding green bars. Several curved yellow arrows, representing “Labour flow,” are drawn. A yellow bar from the bottom green bar is curved upward to end at the top green bar. A yellow arrow from the bottom blue bar is pointing to the third blue bar from the top. Similarly, a yellow arrow from the second blue bar from the bottom is pointing to the top blue bar.Example job schedule with labor flow. Source: Authors’ own work
