A key concern for the area of discrete event simulationmodelling is to encourage its adoption and use by non-specialists. To achieve this it is important that we focus on developing techniques and tools that can be used easily by people from outside the simulationmodelling community. This paper explores the usefulness of one particular simulationmodelling technique, hierarchical activity cycle diagrams (H-ACDs). We suggest that though H-ACDs are useful to simulation specialists, they can often be overly complex and can discourage non-specialists. We propose and develop a simplified version of H-ACDs, which we call simplified hierarchical activity cycle diagrams (SH-ACDs). We then go on to discuss the development of a simple graphical user interface which is the front-end to a modelling environment which supports the development of SH-ACDs. We discuss the way that an interface of this type can offer those without experience in simulationmodelling the opportunity to develop simulations of their problem domain. We suggest that the SH-ACDs in conjunction with a suitable graphical interface can offer a potentially significant contribution by promising to open up the field of simulationmodelling to non-experts.

Describes an approach to the development of computer simulations-the 'four-phase' approach-which aims to be more accessible than established approaches to non-specialist developers in manufacturing system design. This paper briefly reviews the traditional 'three-phase' approach and highlights its potential drawbacks. It then goes on to suggest that the benefit of the four-phase approach over the more established three-phase approach that it is more suited to simulations developed through iconic representations. Such representations are seen as central to the spread of simulationmodelling into application domains such as manufacturing system design. The paper also suggests that complete modelling environments can be built around those iconic representations which allow the user the opportunity to concentrate on the manufacturing system's behaviour rather than on developing computer code to support the model. This is achieved by the automatic generation of the code from the iconic representation. modelling environments that provide such a focus are likely to be more usable by people without any specialist simulation background.

One dominating view of simulation, especially when graphical methods or notations are used to construct simulations, is that of transaction flow. This paper identifies six behavioral patterns that highlight problems with this view. An object-oriented method of constructing simulations is introduced which consists of embedding simulation entities in "yokes", which can be thought of as reified contracts.
