A dynamic business modelling approach to design and experiment new business venture strategies
2018
Abstract Business Modelling has evolved as a key activity to reflect new business venture strategy by framing the way a firm will operate and how it will function in achieving its goals (e.g., profitability, growth, innovation, social impact). However, scholars and practitioners have criticized the adoption of a too static perspective in the design and use of conventional Business Model representations. Such a static perspective prevents nascent entrepreneurs experimenting with their Business Models and, as a result, identifying the most effective strategies, especially in terms of business sustainability and profitability. In this paper, we argue that combining conventional Business Model …
Multiscale Granger causality
2017
In the study of complex physical and biological systems represented by multivariate stochastic processes, an issue of great relevance is the description of the system dynamics spanning multiple temporal scales. While methods to assess the dynamic complexity of individual processes at different time scales are well-established, multiscale analysis of directed interactions has never been formalized theoretically, and empirical evaluations are complicated by practical issues such as filtering and downsampling. Here we extend the very popular measure of Granger causality (GC), a prominent tool for assessing directed lagged interactions between joint processes, to quantify information transfer a…
Strategic Asset Building and Competitive Strategies for SMEs which Compete with Industry Giants
2014
This chapter studies companies which are arguably business super-heroes – the small firms which despite the apparent handicap of very limited resources are able to compete against much larger, multinational firms – the micro-giants Davids that take on Goliaths. Through a process of detailed case studies of actual firms, analysis of asset structure, and experiments with a simulation model, the relationships between key assets, critical success factors, and micro-giant competiveness are explored. The model produces six scenarios reflecting different strategies for developing tangible and intangible assets and, critically, the balance between them. A level of aggression is needed in asset buil…
Disabled People from Welfare to Jobs: A Decision Support Tool
2012
Despite repeated statements from successive governments in Norway, disabled people employment rate remains unchanged since 2000. A range of studies to describe and analyse the situation qualitatively and quantitatively have been performed, however we have not been able to find any study containing a decision support tool focusing on this issue. This paper presents a simulation model, built using the System Dynamics methodology. The model focuses on enabling disabled people to move from welfare to work, incorporating attitudes of disabled people and employers. The model is designed to cover selected factors that are believed to enable and encourage disabled people to take up jobs. It is inte…
Accessibility of Norwegian Municipalities Websites: A Decision Support Tool
2011
Access to public websites is crucial to assure equal opportunities for all citizens to participate in society. Although, a range of studies to analyse the accessibility of websites have been carried out, we have not been able to find any study evaluating the effect of managerial decisions on the accessibility of websites. This paper presents a demonstrator simulation model, built using System Dynamics methodology. The model focuses on accessibility of Norwegian Municipal websites, and is intended to be used as a decision support tool, mainly for managers responsible for website development and maintenance. To build the underlying model we have used information collected from in-depth interv…
Public Sector Applications of the System Dynamics Approach
2010
The article discusses various reports published within the issue, including one by Carmine Bianchi on understanding public sector from different levels and perspectives, one by Mauro Lo Tennero on the aspiration and structure of Sicily to enforce public policy, and one by Nuno Videira and colleagues on the use of group model building in the public sector to concur sustainable policies.
Territorial Governance, E-Government and Sustainable Development Policy: A System Dynamics Approach
2013
Part 1: Research Foundations; International audience; The goal of this paper is to demonstrate how system dynamics modelling can be used in e-government policy and systems as an aid to spport territorial ananlysis, planning and governance, sustainable performance in urban areas and the assessment of policy outcomes. Topics such as renewable energy, efficiency, the design and exploitation of urban energy, water and waste management infrastructure and the alignment of different stakeholders provide relevant fields of study for the analysis of this paper. Specifically, we reflect upon the way in which a preliminary dynamic performance management model of an exemplary case study can be used to …
MODELLI DI SYSTEM DYNAMICS PER IL MIGLIORAMENTO DELLA PERFORMANCE AZIENDALE. VERSO UN SISTEMA DI PROGRAMMAZIONE E CONTROLLO PER LO SVILUPPO SOSTENIBI…
2009
Il libro affronta il tema del governo dello sviluppo sostenibile e del miglioramento della performance aziendale attraverso sistemi di programmazione e controllo che si avvalgano di modelli di system dynamics. Il testo è corredato da numerosi casi applicativi e modelli di simulazione. I casi e i modelli riportati derivano da applicazioni realizzate presso aziende operanti in settori diversi (es. telecomunicazioni, assicurazioni, tessile, servizi bancari, produzione su commessa, commercio all’ingrosso) e con riferimento a problematiche differenti. Gli ambiti decisionali analizzati con i modelli riportati nel libro tendono a coprire gli aspetti maggiormente critici della gestione strategica e…
Overcoming Myopic Behaviour in Intellectual Capital Policies through Interactive Learning Environments based on System Dynamics and Accounting Models
Using simulation to analyze renewables penetration in Brazil
In the new global economy, renewable energy has become a central issue for the competitive. Renewables are the main source of the Brazilian electricity generation sector. This article analyzes the vulnerabilities of hydropower generation and wind power penetration in Brazil. The study presents the results obtained from preliminary analyses of renewable energy’s market penetration in Brazil. Simulation results show the climate variation effects on hydroelectricity generation as well as wind power penetration.
