For the high-cost stonework transport case (VB4-hi), the 70 runs implemented produced eight discrete solutions (Sol1΄–Sol6΄) as far as their FV is concerned. The 70 runs required about 10 min of simulation time. Table 6 presents the FV, VB1, VB2, VB3 and VB4 values of all solutions as well as the increase (%) in FV solutions exhibited compared to the best solution Sol2΄. A green–white–red colour scale is utilized to better present low–medium–high values per column. Table 7 presents the different dam – BP layouts/configurations of these eight solutions, including the number of dams, dam locations and respective dam heights, together with the BP's location, as well as the number of appearances of each DL in the eight solutions. Six out of eight solutions constitute distinct strategies, judging by the dam locations’ layout alone (Sol1΄, Sol3΄–7΄), while Sol2΄ and Sol8΄ can be categorized in the same strategy. They exhibit the exact same layout (L1, L2, L46, L59 and L61), with the only difference being the DH at L2 (2 m for Sol2΄, 1 m for Sol8΄). Hence, the eight solutions of VB4-hi correspond to seven basic management strategies.
