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 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..

The Spanish air traffic control provider – AENA - has used modelling and simulation tools from Lanner Group to investigate how the predicted increase in flight numbers through the country’s airspace, will impact on the efficiency of the services they provide.

Airbus has used WITNESS simulation software to play a key role in the development of a massive £21 million surface treatment plant at its Broughton factory in the U.K. The plant is believed to be the biggest fully automated facility of its kind in the world. WITNESS was used to provide more than traditional “what if” simulation. An evolving sequence of models was built to optimise the layout and..

Airbus A380 Airbus relied on WITNESS simulation software from the Lanner Group to help optimize the production process and facility layout for its new A380 wing production complex in Broughton, UK. The new building, known as the west factory is one of a number of facilities that Airbus is constructing across Europe to support production of the A380 and other manufacturing activities. The A380 is..

Several simulation studies have been carried out for and by Air France in their baggage sorting centres at Roissy Charles de Gaulle 2 (CdG2) airport in France. The main purpose of these studies was to determine resource requirements for the various baggage handling operations. The simulation models were built using WITNESS by trained Air France engineers and by a team of experienced Lanner consu..
