Group model building: a collaborative modelling methodology applied to critical infrastructure protection
2012
Large crises management, affecting CIs needs multidisciplinary knowledge including technical, economical, social, political, legal and managerial knowledge. Being these crises international a huge variety of agents is involved in their response. This situation concludes in a set of stakeholders who only have fragmented knowledge. In the presence of dispersed and incomplete knowledge, and of fragmented and disrupted crisis management, the collaborative approach group model building (GMB), where modelling experts unify fragmented, tacit knowledge from domain experts, is a valuable option. However, GMB has been little used in CIP. We have done so in the context a European project on crisis man…
Green Data Centres integration in smart grids: New frontiers for ancillary service provision
2017
Abstract The paper presents a study, conceived within the GEYSER FP7 co-funded European research project, on the ancillary services that Green Data Centres (GDCs) can provide, focusing, in particular, on spinning reserve. More in detail, the main contribution of the paper is to show how GDCs can be involved in the secondary frequency regulation process of a smart distribution grid, for contrasting the disturbing effects of unexpected variation of the energy production. With this aim, a real data centre, owned by Engineering S.p.A., is simulated as connected to the Medium Voltage IEEE 14-bus test grid where some RES-based generators are supposed to exist. Simulations are carried out in order…
Intelligent learning environment for better student’s academic performance
2021
In this paper, the authors aim to develop an intelligent learning environment model designed to improve students’ academic performance. Methodology: Referring to the litarature, the authors identified and analyzed a number of relevant issues that influence the specific components of an intelligent learning environment. These aspects were quantified using performance indicators defined on the basis of the specific objectives of each aspect chosen. Results: Following the analysis, the authors developed a model of intelligent learning space, and for its representation, we used conceptual modeling. Conclusions: Finally, the authors propose the prevalidation of the model using the dynamic modeli…
Modeling the escalation/de-escalation of response operation levels in disaster response networks using hierarchical Colored Petri Nets (CPN) approach
2018
In emergency situations, the first responders need to act promptly to situations, while the disaster management authorities' response might not be at the same speed. Delays by disaster management authorities had a direct impact on response operations led response teams to the shift away from command and control structures to net-centric ones. This paper is part of a study to examine patterns of emerging organizational relations and coordination structures in disaster response operations. Understanding coordination patterns in disaster chaos can help to integrate those patterns in the planning and execution in the modern disaster management operations. We use dynamic modeling methods to anal…
Experimenting lean dynamic performance management systems design in SMEs
2018
Purpose The purpose of this paper is to frame the potential benefits of lean dynamic performance management (PM) systems for small and micro-enterprises. Such systems may exploit the entrepreneur’s tacit knowledge and build on managerial competencies, by incorporating individual attributes into organisational routines. Design/methodology/approach The paper suggests the use of insight models based on the combination of lean PM tools and system dynamics (SD) modelling. Based on a number of exemplary cases, the paper discusses the potential benefits of these models, in respect to four specific contexts: artisan, new company start-up, established firm and micro-giant company. Related to such c…
Designing dynamic performance management systems to foster SME competitiveness according to a sustainable development perspective: empirical evidence…
2015
The role of performance management (PM) systems has become crucial for steering small-medium enterprises (SMEs) to successfully compete during the ongoing critical economic transition. To improve decision-maker strategic learning processes, traditional PM frameworks need to be combined with system dynamics (SD) modelling. This paper shows how to design and use a dynamic performance management (DPM) approach to assess and support SMEs competitiveness according to a sustainable development perspective. The emerging framework is applied to a real case of an Italian small business to analyse the empirical effectiveness of the approach hereby suggested.
Supporting start-up business model design through system dynamics modelling
2017
Purpose The purpose of this paper is to explore how system dynamics (SD) modelling can provide a methodological support to business model (BM) design with the intent to better communicate business strategy and manage performance. Design/methodology/approach After a literature review of the field and an analysis of the strengths and limitations of conventional BM frameworks, the paper illustrates and discusses an approach that combines such a framework with SD modelling. A single-case study design was selected to explore the implications and limitations of using this combined approach to business modelling. Findings The methodological support provided by SD to BM design may effectively impr…
Applying Dynamic Performance Management to Foster Collaborative Governance in Higher Education: A Conceptual Framework
2020
Higher education is characterized by growing complexity and uncertainty, which highlight how wicked issues cannot be addressed by one organization acting alone. A collaborative governance approach is here proposed to tackle these issues. Such a perspective has been implemented widely, from public services design and delivery to infrastructure development and environmental protection. Although higher education is not less critical than the above areas, less attention has been paid to collaborative governance in this field. To foster collaborative governance in higher education, based on a literature review, we develop a conceptual framework using the dynamic performance management approach. …
Overcoming managers’ myopic decisions in a waste collection company
2019
Purpose The purpose of this paper is to show how the changing interrelationships between fleet management, human resources and outsourcer capacity areas are likely to counterbalance managerial policies, thereby generating a performance decay. The use of system dynamics modelling in a waste collection company offered an effective contribution to support decision makers to overcoming myopic decisions. Design/methodology/approach Literature review and a case study analysis (including interviews with company actors and data gathering) offered the basis to build a system dynamics model. The model built was then used to run simulations sessions to assess alternative investments decisions. Findin…
Combining system dynamics modelling and management control systems to support strategic learning processes in SMEs: a Dynamic Performance Management …
2015
Traditional management control systems, mainly centred on accounting-based measures, are widely recognized as useful tools to support Small and Medium Enterprises (SMEs) managers and entrepreneurs in steering business development. However, due to the increasing turbulence and dynamic complexity that characterize today’s competitive arenas, such systems need to be combined with simulation-based methodologies in order to improve entrepreneurial learning processes and, as a result, better detect possible crisis symptoms and weak signals of change—emerging from the business environment—to promptly react. Therefore, the aim of this paper is to show how a combination of traditional management con…
