Abstract
In an effort to increase efficiency, a pharmaceutical company wants to regulate the allocation of warehouse workers . At initial observation, it was identified that the utilization of workers in the Warehouse Material Section was low. This is because workers do not comply with supervisors who make allocations based on experience. This research was conducted to assist companies in allocating workers according to their workloads with the hope of increasing utility and reducing the allocation of excess workers. The study began by selecting non-administrative work and measured standard time as a reference to its workload with work sampling methods . After that, scheduling with heuristic and optimization methods is designed. Scheduling is done twice, scheduling with observational data is used to analyze the differences in initial conditions, the results show a 15% increase in utilization and a decrease of 0.2 in the average needs of workers. The second scheduling with historical data is used to analyze the differences in the results of the two methods, in cases where there is a conflict between activities in a period the heuristic method allocates workers to the most important jobs first while the optimization method allocates workers to jobs that produce the least amount of work remaining.
