[en] Nomacorc has a highly volatile demand for the entire range of its products. To meet this variability, the factory has at its disposal a fixed machinery park and uses existing inventory. However, the demand for generic products only represents 17% of the total sales, which makes it difficult to produce large stocks in advance. Moreover, the production has a four day lead time for any received order. Therefore, the company faces a lack of production capacity.
This lack of capacity has been analysed during the project to understand the real causes. The results that emerged demonstrate that some production lines are not used to their full capacity, while others are. The problem of seasonal demand in the production line continues throughout the year.
The solution put forward in the project is to increase the machinery park’s flexibility to distribute the workload equally on each production line. Several proposals were given to the company during the project cycle. A program was created to address the impact of these different changes. It appears that Nomacorc could save up to 210.000€ each year by making these changes.
We would expect savings to be even higher if all unexpected events are taken into account. Indeed, if a machine fails or a sudden increase in demand appears during the year, the machinery park could be changed to adapt to these unforeseen events while it would not be possible with a less flexible machinery park.
By implementing this project, the production will be better prepared for the variability of demand. It will increase productivity while decreasing delays, overtime pay and inventory. By being more flexible, Nomacorc would better react to unexpected events and improve working conditions for employees, as well as returns for stockholders.
