one of the main challenges for manufacturers in production systems on order is balancing between orders, inputs and limited resources. hence, they have to choose some orders and reject the others. in addition, work schedule must be considered in order acceptance. in this research the integrated problem of scheduling and order acceptance in a no wait flexible flow line production system is discu...

In the present paper a bi-objective integer linear programming problem (BILP) is discussed. The main effort in this work to effectively implement ?-constraint method produce complete set of non dominated points. convergence algorithm has been established theoretically. Further comparative study some existing also made.

During the clinical years, medical students frequently experience physical and mental health problems, which are exacerbated by their work schedules. To address this issue, we develop a bi-objective mathematical model in study. The two objectives of 1) balancing workload each student group 2) minimizing deviation among groups. In addition, includes constraints on ward rotation sequencing. requi...
