“…Hence, ABM is a specific type of modelling, where the real world system that is modelled consists of (one or multiple) autonomous entities (e.g., human beings, animals, or intelligent artefacts). According to Shannon (1975), a model is a representation of an object, system or idea other than that of the entity itself. In a model the most important concepts of the relevant real world system are described, as well as the relationships between them.…”

Computational modelling techniques, originating from fields like Computer Science and Artificial Intelligence, may be beneficial for criminological research. Because of their formal nature, computational models can be processed by machines that operate on them, for example for the purpose of simulation. As a consequence, these techniques may help gain insights that lacked based of purely informal theories. A well-known example of such a technique, which has become widely applied within criminology, is called agent-based modelling. Agent-based modelling (ABM) is a computational method that enables a researcher to create, analyse and experiment with models composed of agents, i.e., autonomous pieces of software that interact within a computational environment (Gilbert, 2008). In the current article this technique will be explored in depth. First, I will give a description of the technique and present the architecture of an ABM. Subsequently, I will apply the technique to a simple toy example in the context of a simulation model of the bystander effect, to demonstrate the possibilities of the approach. I will discuss some pros and cons of the approach and present related work to help appreciate the benefits of applying ABM to different criminological research questions. Hopefully, this will provide readers with the necessary knowledge to consider the use of ABM in their own research.

“…The Simulation generator consists of two components, the simulation software part and the expert system , with a possible definition for expert systems according to BG Buchanan as "An expert system is: A knowledge-based system that contains expert knowledge rather than general knowledge. It is a problem solving program that solves Figure 2 The Software Lifecycle substantial problems generally conceded as being difficult and requiring expertise": Expert systems are usually concerned with tasks that are normally performed by specially trained people [1,4]. There are in general three components to an expert system, the knowledge base, production rules and inference engine, with the knowledge base containing the expert knowledge needed for problem solving or decision support (Figure 1).…”

Successful simulation studies depend on a variety of expertise such as statistics, computer programming, systems analysis and design techniques. Unfortunately these requirements limit the availability of competent simulation analysts, while simulation applications are in demand. This paper presents a possible solution to the shortage of expert simulation knowledge through the design of a simulation generator, a software tool that translates conceptual simulation models into computer code. The design process for the expert system and simulation components of the simulation generator uses an adapted software lifecycle methodology. OPSOMMINGSuksesvolle simulasiestudies hang van verskeie kundigheidsonderwerpe af, soos byvoorbeeld statistiek, programmering, stelselanalise en ontwerptegnieke. Die vereistes beperk die beskikbaarheid van geskikte simulasiekundiges , ten spyte dat simulasietoepassings in aanvraag is. Die artikel bied '0 moontlike oplossing aan vir die tekort aan simulasiekundigheid, deur die ontwikkelling van simulasiegenerators te bespreek, wat rekenaarprogrammatuur is wat konseptuele simulasiemodelle in rekenaarkode omskryf. Die ontwerp van die simulasiegenerato r se ekspertstelsel-en simulasiekomponent is gebaseer op ' n aangepaste rekenaarprogrammatuurlewenssiklus metodologie.

Although the technology exists for more advanced applications of automated guided vehicles in flexible manufacturing systems, the current employment of these vehicles in material handling generally subscribes to a simple mode of operation: single-load-carrying capacity for each vehicle and unidirectional traffic on each route of the system. Through a simulation programme, this study investigates the.effect of several key factors related to the automated guided vehicles on the overall performance of a flexible manufacturing system. These are the number of pallets allowed in the system, the number of vehicles used and the carrying capacity of each and the input and output queue capacities of the machining stations; finally bidirectional traffic is allowed in some routes. The results show that there is a strong interaction among these factors and reveal their combined effects on the throughput from a small flexible manufacturing system. Upon the user's request, the simulation program also provides the animated colour graphics of the system to view developments concurrently under the selected decision values through time.
