Modeling the natural gas supply chain for sustainable growth policy
2020
Abstract Natural gas has been used globally as a transitional fuel for supporting a green-energy-supply strategy, which has been questioned for the intermittence and lack of reliability of renewables. This paper proposes a System Dynamics model for assessing alternative security of supply policy along the natural gas value chain. The model incorporates demand, transport, production and reserves of natural gas variables according to a systemic perspective. It also includes a module for evaluating the effect of natural gas price on the demand and supply levels, respectively. Alternative supply policies are evaluated under different scenarios. The chosen case-study focuses on the Colombian nat…
Data-based modeling of vehicle crash using adaptive neural-fuzzy inference system
2014
Vehicle crashes are considered to be events that are extremely complex to be analyzed from the mathematical point of view. In order to establish a mathematical model of a vehicle crash, one needs to consider various areas of research. For this reason, to simplify the analysis and improve the modeling process, in this paper, a novel adaptive neurofuzzy inference system (ANFIS-based) approach to reconstruct kinematics of colliding vehicles is presented. A typical five-layered ANFIS structure is trained to reproduce kinematics (acceleration, velocity, and displacement) of a vehicle involved in an oblique barrier collision. Subsequently, the same ANFIS structure is applied to simulate different…
Managing Sustainable Performance and Governance in Higher Education Institutions : A Dynamic Performance Management Approach
2022
This book aims to cover about a decade of research activities devoted to university management, exploring its specific organizational complexity, and adopting systemic approaches to managing its performance generation mechanisms. It also draws on the field experience spent as the academic delegate for scientific support to strategic planning, management control, performance evaluation, and statistical reporting at the University of Palermo, Italy. This work is included in a series on “System Dynamics for Performance Management.” The fast-changing evolutionary process of global higher education systems systematically poses new challenges related to the appearance of innovative elements that …
Supporting public sector management through simulation-based methods: a dynamic performance management approach
2018
AbstractThough it draws a number of precursors, simulation-based techniques applied to traditional performance management frameworks constitute a novel approach to support public sector institutions in framing organizational performance dynamics and, as a result, improving public service delivery. This paper aims at contributing to the improvement of the outcomes achievable from the use of traditional performance management systems in the public sector by combining them with a simulation-based method named System Dynamics modeling. Such an approach is called Dynamic Performance Management.
A Dynamic Viewpoint to Design Performance Management Systems in Academic Institutions: Theory and Practice
2014
This article illustrates how to design and apply Performance Management systems in academic institutions by identifying and modeling those factors affecting academic performance through a dynamic performance management view. Particularly, combining performance management with System Dynamics modeling may allow academic decision-makers to better identify key performance drivers for pursuing a sustainable performance improvement in universities. In the second section of the article, a number of examples based on empirical findings from a field project aimed at designing a dynamic performance management model for the University of Palermo (Italy) are discussed.
Using System Dynamics to Enhance Performance Management in Local Government: An Application to Residential Refuse Collection
2012
While some scholars have suggested that the forces of New Public Management are now in decline (Hughes, 2003), a clear success story of this reform is the use of performance measurement in the public sector for tracking the outputs and outcomes of service delivery. In fact, research has demonstrated that well-managed performance measurement systems are critical for accurately and systematically demonstrating operational accountability in governmental organizations (Rivenbark, 2007). However, we must be cautious in how we think about the use of performance measurement systems because of their two distinct parts as described by de Lancer Jules and Holzer (2001). The first part involves adopti…
Dynamic business modeling for sustainability: Exploring a system dynamics perspective to develop sustainable business models
2019
In the last decade, business models for sustainability have gained increasing attraction by corporate sustainability scholars with international conferences and scientific journals encouraging the development of the debate on their design, use and innovation processes. Capitalizing on the basic principles, requirements, and methodological limitations found in the literature on sustainability‐oriented business model design, this paper aims to conceptualize a dynamic business modeling for sustainability approach, which combines an adapted sustainable business model canvas and system dynamics modeling. To this end, the paper also illustrates the key operating principles of the proposed approac…
