1. IJfs, S.R. Improving the Logistical Process Around Cross-Docking of Products from Packaging Lines: A Case Study at the Zoeterwoude Brewery of HEINEKEN Nederland Supply:.

Degree: 2015, Delft University of Technology

HEINEKEN Nederland Supply continuously strives to improve its logistical processes in order to be able to serve its customer better, but at the same time to reduce costs. Within the Zoeterwoude Brewery, the Customer Service & Logistics department is responsible for the supply of the materials to the packaging lines, but also for the loading process of the pallets arriving at the warehouse. Increasing output from the packaging lines have caused regular spill-back of finished goods towards packaging line 2, 4 and 7. This spill-back causes standstill of the filling machine and therefore a drop in the performance of the packaging lines. HEINEKEN Nederland Supply has a large number of open sales orders and is already producing in over-time. This means that every lost production hour leads to sales losses for the company and the potential loss of valuable customers. The objective is to improve the loading process such that the capacities and planning are better aligned with the supply of the packaging lines. This leads to the following research question: How can the loading process at the Zoeterwoude Brewery of Heineken Nederland Supply be improved such that the capacities within the process and the corresponding planning are better aligned with the supply of packaging line 2, 4 and 7? This research is framed within the DMAIC methodology (and performed by following on the Theory of Constraints). This research starts by analysing the current loading process and influencing factors. It is found that the amount of pallets that is being processed by CS&L is growing at a fast rate. Especially the loose-loaded pallets are leading to an increase in pallets. The share of these pallets grew in total from 6% in 2012 to 12% (even 43% for packaging lines 2, 4 and 7) in 2014 and is expected to grow even further. The process is found to be a complex socio-technological part of the brewery and is influenced by many factors, both controlled internally and externally. The next step in this research was to collect data related to this process and to obtain valuable information from different viewpoints. From the analyses the root-causes of the problem are found. From the bottleneck analysis it is found that the transfer car between the cross-docks and the loading stations is not able to handle certain product combinations entering the warehouse. The capacity of the loading operators is sufficient, although requiring two skilled operators. Unexpected disturbances lead to buffers (cross-docks) being occupied, after which the process is not able to restore itself because of a lack of over-capacity of the transfer car. From the remaining analysis it was found that the unexpected disturbances to the process are problems with the availability of containers, human errors, lack of communication, lack of skilled operators and the lack of warehouse capacity. The loading process can be improved by reducing the input to the cross-docks. This can be done by limiting the flow from line 41 and 42 by removing the pallets locally.

2. Oner, Erdinc. An Evaluation of Entrance Ramp Metering for Freeway Work Zones using Digital Simulation.

Degree: PhD, Integrated Engineering (Engineering and Technology), 2009, Ohio University

Entrance ramp metering in freeway work zones was investigated to develop a set of guidelines for entrance ramp control strategies in freeway work zones considering the freeway mainline throughput and local traffic access to freeways and hourly traffic volumes for the freeway mainline and freeway entrance ramp in this study. The basis for this investigation were the historical hourly traffic volume data and the cumulative interarrival time (IAT) data for signalized and non-signalized freeway entrance ramps and the freeway mainline, which were measured at different freeway work zones in Ohio using microwave radar trailers. The cumulative IAT distributions for signalized entrance ramps were developed and the cumulative IAT distributions for freeway mainline and signalized entrance ramps were extrapolated in order to be able to determine IATs for a few vehicles up to 2500 vehicles/hour (vph). Two separate Arena simulation models, ran on a PC, were used to investigate spill back queues from entrance ramp metering signal back to the local (arterial) road and to investigate merging of the entrance ramp traffic and determine queue lengths from the freeway mainline merge area back to the ramp metering signals for different entrance ramp and freeway mainline rightmost lane hourly traffic volumes, truck percentages, and ramp metering signal intervals at signalized and non-signalized freeway entrance ramps. Arena simulation models were validated using Pollazcek-Khintchine formula and IATs based on negative exponential distribution and number of vehicles merging into the freeway mainline rightmost lane. The analysis of the maximum queues determined using Arena simulation models showed that the use of ramp metering signal interval, which is 90% of the metering signal interval that would be equal to process ramp demand in an hour (100%), will result in smaller maximum queues for signalized and non-signalized freeway entrance ramps, while on the other hand not increase the maximum queue from freeway mainline merge area back to ramp metering signal considerably. A set of guidelines for temporary entrance ramp control strategies in freeway work zones for traffic engineers to design and implement an entrance ramp control strategy including ramp metering was established based on the freeway mainline traffic throughput and local traffic access to freeway importance levels and hourly traffic volume levels for freeway mainline and entrance ramp. These guidelines may also be applied to regular freeway/entrance ramp situations without work zones. Advisors/Committee Members: Zwahlen, Helmut T. (Advisor).
