Abstract
U-shaped Line (UL) utilizes many manufacturing industries. It applies the just-in-time principle, the lean manufacture, and the quality improvement. It reduces the waste in the manufacturing operation. This paper presents two UL models which consist of eight certain tasks and three uncertain tasks. Two UL models include UL No.1 and UL No.2. The uncertain tasks assume the time distribution that is discrete. The uncertain task time of UL No.1 classifies to three types. The uncertain task time of UL No.2 classifies to five types. The objective function of two UL models is the minimum workstations. Two UL models formulate on a zero-one integer linear programming. This academic work applies MATLAB R2014a which solves the solution of two models. The procedure is run by INTLINPROG toolbox. The solution of the uncertain tasks for UL No.1 is the optimistic time. The solution of the uncertain tasks for UL No.2 is the most optimistic time. The number of workstations of UL No.2 is less than the number of workstations of UL No.1. The most early finish tasks which assign along the UL line affect the minimum workstations.
