Delivering performance, for any enterprise, is an ongoing challenge. If an enterprise can move from strategy to execution successfully, then driving performance becomes the core action guaranteeing success. Business Process Management (BPM) allows complete business processes to be modified, replicated and "tuned" more effectively than the classic development models that do not separate flow from..

Discrete-event simulation is one of the most popular modelling techniques. It has developed significantly since the inception of computer simulation in the 1950s, most of this in line with developments in computing. The progress of simulation from its early days is charted with a particular focus on recent history. Specific developments in the past 15 years include visual interactive modelling, ..

Business modelling and simulation from the Lanner Group have helped the South Yorkshire Passenger Transport Executive (SYPTE) to finalise its plans for the new Doncaster Interchange that will open in 2003. The models created using Lanner’s WITNESS program were used during the planning and design phases to test concepts and support negotiations with the local authority, transport operators, devel..

This paper presents a decision analysis technique on the results obtained from product development process model simulation. The design process involved in the industry is used as a sample application. The software used for simulation is called WITNESS. The simulation model uses the design structure matrix to capture the information flow between tasks where the tasks could be sequential, paralle..

This paper discusses the integration of value stream mapping (VSM) and discrete event simulation to further the continuous improvement goals of lean manufacturing.

This paper introduces and critiques recent project work carried out by Consultants at Lanner Group in Collaboration with Manufacturing Engineers and Simulation Specialists at Ford Motor Company's PowerTrain Operations. These projects enable Simulation Specialists and manufacturing Engineers alike to model and experiment with planned Engine Assembly lines. Since so much commonality exists, both b..

The rapid changing business environment of high-tech asset intensive enterprises such as semiconductor manufacturing constantly drives production managers to look for better solutions to improve the manufacturing process. Simulation, though identified to be the most appropriate technique to generate and test out possible execution plans, suffers from long cycle-time in the process of model updat..
