This paper aims to develop a system dynamics model in order to formalize causal interdependencies between safety factors (technical, organizational and human). These factors define safety conditions in a complex industrial system. It is a systemic approach founded on the method of system dynamics and the case study is a storage unit for chemical products located in Morocco. System dynamics usin...

An extended abstract for ProSim’04 May 24-25, 2004 http://www.prosim.pdx.edu/prosim2004 A standard methodology in the process simulation community is to build simulations using high-end visual programming (VP) system with powerful graphical front-ends. Many such VP tools exist including Vensim (see Figure 1), the Statemate state-based simulation model by i-Logix 1, the Extend discrete event sim...

Bass Model, the most representative accomplishment in the field of product diffusion, is built on a series of assumptions which seriously limit the applied range of the model. This paper improves Bass Model so that it could be applied to competitive products. Also, this paper presents an expression of the analytical form of product margins. By taking the unit variable cost’s learning effect int...

This study conducts dynamic simulation by using System Dynamics Theory and Vensim software which investigates the relationship between consumer satisfaction and operations strategies of campus restaurants. This study simulates the effects of four priorities including service quality, profits of restaurants, turnover rate of restaurant stands and consumer satisfaction which affect the operations...

Based on system dynamics theory, this study used Vensim software to develop the Stock-Flow Diagram. This study used the Dynamic Situations of system dynamics to perform dynamic simulation on the effect of sports promotion strategy on Taiwan’s national health care and its relevant medical expenditure and future expenditure. Moreover, this study used the simulation results as reference for strate...

An approach using component technology for the development of System Dynamics models is introduced. At first a brief introduction of System Dynamics, its modeling perspective and its modeling elements is given. The representation of System Dynamics models in Vensim, an interactive software environment for the handling of such models, is described. On this basis the paper provides an approach fo...

The central bank needs to predict the macroeconomic conditions in the future when it makes a new monetary policy. Namely, we make the optimal monetary policy with a comprehensive analysis on the domestic output, money supply and inflation rate. This article selects the datum of the National Bureau of Statistics of China, the People's Bank of China, and the Customs Statistics Information Network...

Uncertainty in Supply Chain Management can lead to unsuitable services to customers, but it can be overcome through having an emergency inventory. Due to high costs of inventory, a general inclination exists towards a minimum inventory. So, one of the objectives of Supply Chain Management is to coordinate all activities throughout the chain, so that simultaneously with reducing commodity invent...

Amaç –Bu çalışma kapsamında, Türkiye’nin elektrik piyasasını modellemek için Sistem dinamiği modeli (SDM) Vensim PLE programı ile oluşturulmuştur. modeli, bu tür karmaşıklıkları uygun bir yaklaşımdır. Yöntem –Sistem dinamiği, geri bildirim sistemlerine dayanan metodolojidir. Dinamiği Jay Wright Forrester tarafından geliştirimiştir. Forrester'ın metodolojisi, karmaşık ve dinamik sistemler bilgis...
