Purpose: Understanding how the structure affects logistical performance and food security is critical in the supply chains of perishable foods (PFSC). This research proposes a system dynamics model to analyze the effects of structures: lean, agile, flexible, responsive and resilient, in the...

Both mathematical modelling and simulation methods in general have contributed greatly to understanding, insight and forecasting in many fields including macroeconomics. Never-theless, we must remain careful to distinguish model-land and model-land quantities from the real world. Decisions taken...

We investigate masked financial instability caused by wealth inequality. When an economic sector is decomposed into two subsectors that possess a severe wealth inequality, the sector in entirety can look financially stable while the two subsectors possess extreme financially instabilities of...

The main aim of this study is to empirically investigate the factors influencing the capital structure decisions of listed firms in Ghana. In examining the determinants of capital structure, 28 firms listed on the Ghana Stock Exchange were used for a time period of 8years, spanning from...

The three-sector framework (relating to agriculture, manufacturing, and services) is one of the major concepts for studying the long-run dynamics of the economic structure. We summarize the empirical/theoretical literature consensus by formulating ‘economic laws’ of long-run structural...

Within a financial market where a risk-free bond and a long-lived risky asset are exchanged by investors with heterogeneous trading rules, we assume that the investors most exposed to the risky asset are subject to joint liquidation needs. The latter encompass a risk whenever the market impact...

System resilience is the ability for complex, dynamic-adaptive socio-technical systems to absorb and rebound from trauma or stress, and to avoid "jousting with dragons" where results are uncertain and often fatal. In a safety context, the term "dragons" originates from Professor David Woods at...

В статье рассмотрены подходы к детерминированному моделированию устойчивости социально-экономических систем. Указано, что формализированные подходы к...

Global emissions beyond 44 gigatonnes of carbondioxide equivalent (GtCO2e) in 2020 can potentially lead the world to an irreversible climate change. Employing a novel dynamical system modeling approach, we predict that in a business-asusual scenario, it will reach 61 GtCO2e by 2020. Testing...

This text was written as part of the project "Modelling of Complex Systems for Public Policy". It reviews the classical authors who jointly contributed to establish the elements of what could constitute a "science of complexity". Based on the original writings of these authors, the text...

Analysis of economic state of tourism enterprises of the regional level, developed in the phase of economic recession, allows stating that economic stability should be based on use of anti-crisis models, one of which is the model of co-operation in organisation of the regional tourism business....

Анализ экономического состояния туристических предприятий регионального уровня, развивающихся в фазе экономического спада, позволяет констатировать, что...
