OIA Global is a third-party logistics provider that is locally based here in Portland Oregon. It seeks to minimize the labor cost required to fulfill their customer demand of international shipments. In this paper, we used two different models, current situation and redesigned future way, of Integer Linear Programming (ILP) to quantify and examine the potential benefits of a new method to assign tasks to workers. The result shows 30 workers- 50 percent of all of employees are not working on any task in current situation analysis. For the future employee utilization, we suggest 49 of 60 current workers are not needed which the vice president of OIA also considers our findings are valuable for OIA.
