a multi-objective programming to increase labor efficiency of a truck hub: a case study

the problem of staff scheduling at a truck hub for loading and stripping of the trucks is an important and difficult problem to optimize the labor efficiency and cost. the trucks enter the hub at different hours a day, in different known time schedules and operating hours. in this paper, we propose a goal programming to maximize the labor efficiency via minimizing the allocation cost. the proposed model of this paper is implemented for a real-world of a case study and the results are analyzed.
