Abstract:This research has been conducted at Nijhuis Toelevering B.V. in Rijssen, the Netherlands. Nijhuis Toelevering is one of the biggest carpentry factories in the Netherlands and produces wooden window frames. The demand for wooden window frames has been increasing over the past five years and is expected to keep increasing during the upcoming years. To reach the growing demand, Nijhuis Toelevering needs to increase the production output of window frames as well. A higher output is not possible due to a low final assembly efficiency. By observing the final assembly process and conducting interviews with the employees, we identified the core problem of the low efficiency to be an uncertain availability of materials at the assembly lines. The uncertain availability of materials causes time waste in the final assembly process. This research aims to generate solutions to improve the materials flows within the production facility, in order to increase the efficiency of the assembly process. The main research question addressed in this thesis is formulated as follows: “How to improve the efficiency of the current assembly process at Nijhuis Toelevering? In particular, how to increase the output so as to approach the intended (output increase) target of 50%?”
