Abstract: | In the present paper, an integer goal programming model formulation is presented for the bus transportation crews planning to find an optimal schedule in which each crew is assigned two days off (consecutive or non-consecutive) per week and several goals like upper and lower limits on the total number of crews having consecutive and/or non-consecutive days off on each day, lower limit on the number of crews having consecutive days off on the particular pairs of consecutive days, and minimization of the number of crews having non-consecutive days off, are taken into consideration. The model is demonstrated by a numerical example. |
