in this decade, due to the current competitive environment,reputation of industrial brands is markedly dependent upon theperformance of their supply chain. therefore, it is necessary to examinethe factors affecting their supply chain so as to increase the competitivenessof their chain. productivity is among the most important factorsin the advancement of industry and its evaluation requires the...

Governments have strongly recognized that the proper functioning of critical infrastructures (CIs) highly determines the societal welfare. If a failed infrastructure is unable to deliver services and products to the others, disruptive effects can cascade into the larger system of CIs. In turn, decision-makers need to understand causal interdependencies and nonlinear feedback behaviors underlyin...

The title of this refers to the range of system dynamics applications. This range extends from use as experimental tools in theory development through to the practice of problem solving and investigation of real world behaviours. This paper takes a two-facetted view of the scope of and issues in system dynamics practice based on the author’s personal experiences. The first derives from his role...

This paper focuses on the operational and strategic planning decisions related to the quayside of container terminals. We introduce an integrated operational research (OR) and system dynamics (SD) approach to solve the Berth Allocation Problem (BAP) and the Quay Crane Assignment Problem (QCAP). A BAPQCAP optimization modeling approach which considers practical aspects not studied before in the ...

The System Dynamics (SD) methodology is a framework for modeling and simulating the dynamic behavior of socioeconomic systems. Characteristic for the description of such systems is the occurrence of feedback loops together with stocks and flows. The mathematical equations that describe the system are usually nonlinear. Therefore seemingly simple systems can show a nonintuitive, nonpredictable b...

1. Introduction Understanding concentrated colloidal dynamics in the presence of different pairwise interactions and external fields provides a basis to predict the temporal evolution of colloidal microstructures in diverse phenomena including suspension rheology and colloidal crystallization. However, a microscopic theory of concentrated colloidal dynamics does not yet exist that rigorously in...

The key factors that distinguish algorithms for nonadiabatic mixed quantum/classical (MQC) simulations from each other are how they incorporate quantum decoherence-the fact that classical nuclei must eventually cause a quantum superposition state to collapse into a pure state-and how they model the effects of decoherence on the quantum and classical subsystems. Most algorithms use distinct mech...

Given the growing importance of system dynamics (SD) in solving increasingly complex and dynamic problems any country, we believe SD education will become an imperative leverage point helping us deal with our uncertain future. This study tries to understand causal relationships proliferating by a group modelling approach China. Based on questionnaire survey model building (GMB) workshop, aim ex...

The paper contains a critical description of the roles that System Dynamics (SD) can play for the definition of mediated solutions to complex environmental problems. SD can be either a valuable tool for the definition of shared and consensual solution or a burden and a hindrance. We present a critical review of some basic concepts of SD and discuss some key concepts and their roles in the searc...
