When is it better to use agent-based (AB) models, and when should differential equation (DE) models be used? Whereas DE models assume homogeneity and perfect mixing within compartments, AB models can capture heterogeneity across individuals and in the network of interactions among them. AB...

The main task of this work is to develope a model able to encompass, at the same time, Keynesian, demand-driven, and Marxian, profit-driven determinants of fluctuations. Our starting point is the Goodwin's model (1967), rephrased in discrete time and extended by means of a coupled dynamics...

In this article we develop a supply chain model of four levels through the utilization of system dynamics with Ithink® and Mathlab® softwares to analyze data. The supply chain is studied from the chaos theory perspective, which helps identifying the sensitive variables that can lead to a state...

Chaotic phenomena, chaos amplification and other interesting nonlinear behaviors have been observed in supply chain systems. Chaos can be defined theoretically if the dynamics under study are produced only by deterministic factors. However, deterministic settings rarely present themselves in...

Currently, there are numerous indicators (single and composite) for measuring impacts in the three pillars, though current thinking emphasises the need for system thinking rather than the reductionist concept of pillars. Most existing indices/methods measure single aspects of sustainability and...

Представлен обзор отечественных имитационных моделей регионального развития, базирующихся на системной динамике и агент-ориентированном подходе. Показано,...

В статье рассмотрены проблемы российского рынка труда и поставлены задачи имитационного моделирования структуры, состояния и развития рынка труда....

Understanding the sources of sustained competitive advantage is the fundamental task of strategic management research. An interesting concept of fast strategy has emerged, which builds a firm's competitiveness from its ability to react to change more rapidly than its competitors. We approach...

The study of network representations of physical, biological, and social phenomena has developed rapidly in recent years. This paper presents a review of important results and methods of the science of networks with an application to the field of socio-economic systems. The basic definitions and...
