since the analysis of complex services systems by using mathematical modeling techniques, with considering the random patterns prevailing in them, is so difficult or probably impossible, improvement guidelines are often followed based on the experts' experiences using qualitative methods. in the present paper, by employing a discrete event computer simulation methodology, criminal trial sy...

Despite the claims by software vendors on positive values of an integrated MES and ERP system, there has been no systematic study conducted to assess and evaluate the impact of such an integrated system on shop floor operations. This paper presents a simulation study to evaluate the impact of the MES integration with the ERP system on production lead times. First, we describe a methodology of u...

Timely faults detection in an industrial process is a key aspect for designing a framework for intelligent supervisory control. A way to perform supervisory control is by providing intelligence to the supervision mechanism in continuous processes exposed to faults in order to cope with the identification of a diversity of faults, classify them and to be able to anticipate the consequences deriv...

Manufacturing enterprise decisions can be classified into four groups: business decisions, design decisions, engineering decisions, and production decisions. Numerous physical and software simulation techniques have been used to evaluate specific decisions by predicting their impact on either system performance or product performance. In this paper, we focus on the impact of production decision...

multiple excavators producing multiple products of raw materials are highly complex and exhibit strong interdependencies between constituents. A network of conveyor belts is used for transportation of the extracted materials to different waste dumps or the coal stockpile. Optimal decision-making in short-term planning and production control are impacted mainly by geological uncertainty associat...

This paper gives a short overview of the multiagent-based simulation system PlaSMA. The system provides distributed discrete event simulation with conservative synchronisation. PlaSMA has been developed for scenarios within the logistics domain with simulation agents representing logistic objects like lorries or cargo as well as abstract services like route planning or transport brokering. PlaS...

81 Abstract—According to the fact that network is a class of discrete event system. Discrete-event simulation tool SimEvents is used to build network dynamic model so as to simulate network-induced delay and packet dropout in networked control systems. The concept of round trip time is introduced to estimate network-induced delay, which is compensated by Smith compensator. By using the control ...

Discrete event simulation is used to model, study, plan, and improve systems in which random events play a dominant role. These systems are often driven by complicated mathematical and logical relationships, making it impossible to derive an analytical solution. The journal OR/MS Today cites simulation software as one of the most widely used tools in operations research, due in part to its appl...
