Jobsite Logistic Simulation in Mechanized Tunneling M. Scheffer, T. Rahm, R. Duhme, M. Thewes, M. König, Ruhr-Universität Bochum. Winter Simulation Conference, 2014.
Projects in mechanized tunneling frequently do not reach their targeted production performance. Reasons are often related to an undersized or disturbed supply-chain management of the surface jobsite. Due to the sensitive interaction of production and logistic processes, planning and analyzing the supply-chain is a challenging task.» Lire plus
Generic Simulation Model to Optimize Production and Workforce Planning at an Automotive Suppplier Klaus Altendorfer, Thomas Felberbauer, Daniel Gruber, Alexander Hübl, Proceedings of the 2013 Winter Simulation Conference
This paper presents a comprehensive simulation project in the area of an automotive supplier. The company produces car styling serial and original accessory parts made from plastic for internal and external applications in passenger cars. For the foaming division, which is identified as the bottleneck, different personnel and qualification scenarios, set-up optimizations and lot-sizing strategies are compared with the current situation. Key performance measures reported are inventory, tardiness and service level. The changes in organizational costs (e.g. employee training, additional employees, etc.), due to the scenarios, are not considered and are traded off with the logistical potential by the company itself. Results of the simulation study indicate that a combination of an additional fitter during night shift, minor reductions of set-up times and reduced lot-sizes leads to an inventory reduction of ~10.6% and a service level improvement of ~8% compared to the current situation.» Lire plus
Utilising dynamic factory simulation to improve unit cost estimation and aid design decisions Stuart Jinks, Jim Scanlan, Philippa Reed (University of Southampton); Steve Wiseall (Rolls-Royce plc). Proceedings of the 2010 Winter Simulation Conference.
Utilising dynamic simulation methods to estimate manufacturing resources, can improve unit cost estimation and aid design decisions. This paper introduces a framework specification that combines Computer Aided Design (CAD), Computer Aided Process Planning (CAPP) and Discrete Event Simulation (DES) technologies.» Lire plus
IRS POST-FILING PROCESSES SIMULATION MODELING: A COMPARISON OF DES WITH ECONOMETRIC MICROSIMULATION IN TAX ADMINISTRATION Arnold Greenland, Erica Layne Morrison, David Connors, John L. Guyton, Michael Sebastiani, 2007 Winter Simulation Conference (WSC’07), Washington D.C., December 9-12, 2007
IRS Office of Research Headquarters measures and models taxpayer burden, defined as expenditures of time and money by taxpayers to comply with the federal tax system. In this research activity, IRS created two microsimulation models using econometric techniques to enable the Service to produce annual estimates of taxpayer compliance burden for individual and small business populations. Additionally, a Discrete Event Simulation (DES) model was developed to represent taxpayer activities and IRS administration in postfiling processes.» Lire plus
Modeling S-Class Car Seat Control with AnyLogic — Daimler-Chrysler Modeling Contest Alexei Filippov and Andrei Borshchev. Object-Oriented Modeling of Embedded Real-Time Systems (OMER-2), May 2001, Herrsching am Amersee, Germany, pp 46-50
In this paper we give an overview of the car seat model that was developed for Daimler-Chrysler modeling contest in year 2001 and was awarded the 1st prize. We outline the OO UML-RT based modeling approach that was used and the simulation tool AnyLogic that supports it, and discuss their main advantages with respect to automotive area.» Lire plus
