The global economic meltdown of the late 2000s exposed poor internal processes within many organisations around the world. Previously unshakeable institutions went to the wall and every indicator, from house prices to the number of unemployed, was on a downward trend. As companies begin their slow recovery, they are increasingly looking for ways to reduce working capital by improving operational..

ABSTRACT: Various approaches and techniques have been adopted for reducing cycle time. They can be classified into the following four categories: 1. To establish inter-relationships among critical processes, e.g. pull-type manufacturing; 2. To rationalise the process layout; e.g. cellular layout; 3. To control product mix and product volume released into production lines; 4. To schedule operatio..

Expert systems, and artificial intelligence more generally, can provide a useful means for representing decisionmaking processes. By linking expert systems software to simulation software, an effective means of including these decision-making processes in a simulation model can be achieved. This paper demonstrates how a commercial off-the-shelf simulation package Witness can be linked to an expe..

Dale McQueen at Lanner Group looks at how simulation can provide scientific manufacturing forecasts and predictions, reducing the time needed to bring new products to market

Modeling Component based Simulation This paper describes the development of a generic simulation tool (FORMAT) that uses modular building constructs to create imulation models of the transport of stock from internal stores to delivery points located around engine machining and assembly lines. The model is automatically built in a WITNESS shell containing a CAD factory layout displayed as the bac..

How simulation technology is empowering business leaders in the services sector to drive business transformation and guarantee ROI A white paper by Lanner Group

This paper describes Lanner’s approach to using simulation in Business Process Management. The paper introduces the connection between continuous improvement methodologies and BPM, highlighting the importance of a focus on process and the way in which simulation can provide a unique insight for companies committed to process management. The paper goes on to describe the way in which simulation a..

This paper outlines discrete event simulation and examines the different types of experiments that are performed with simulation models. Optimization techniques are introduced which help establish the best model choices for a defined goal. The paper continues with a discussion on simulation model solution spaces and different types of optimization algorithms. The implementation of the WITNESS Op..
