This thesis investigates different ways in which the productivity of a one-way bottling and packaging production line can be increased. This is done by comparing different configurations regarding machine capacities, machine reliability and buffer capacities with each other. This is done with both the use of a generic model and a case study. The different configurations were compared and combined together with the use of a simulation model. Following from this it can be concluded that it is dependent on the reliability and the machine capacities which shape of protective capacity is the most productive. Besides, also the place in the system where the largest amount of buffer capacity needs to be placed is dependent on the reliability of the machines which are part of the production line.
