Title
  • NEW COMPUTATIONAL RESULTS FOR THE DISCRETE TIME/​COST TRADE-OFF PROBLEM WITH TIME-SWITCH CONSTRAINTS
Author

Notes
  • Recently, time-switch constraints have been introduced in the literature by Yang and Chen (2000). Basically, these constraints impose a specified starting time on the project activities and force them to be inactive during specified time periods. This type of constraints have been incorporated into the well-known discrete time/​cost trade-off problem in order to cope with day, night and weekend shifts.In this paper, we propose a new branch-and-bound algorithm which outperforms the previous one by Vanhoucke et al. (2002). The procedure makes use of a lower bound calculation for the discrete time/​cost trade-off problem (without time-switch constraints). The procedure has been coded in Visual C++, version 6.0 under Windows 2000 and has been validated on a randomly generated problem set.
