Considering the recent lockdowns and travel bans due to COVID-19, novel tourism strategies are necessary to face the increasing need for innovative products and services and to ensure long-term sustainable growth. This study looks into the potential use of drones in providing online virtual tours of open-space tourist attractions. To do so, a novel mixed-integer linear mathematical model is developed to optimally determine the number and location of required facilities and the number of drones assigned to each center. The model is applied to a case study of Rome by selecting six historic sites as the tourist attractions and considering several candidate locations for establishing the facilities. The results of different potential scenarios imply that the project is profitable, even if the demand for virtual tours is low.

<p><em>Regional prosperity not only depends on economic issues but also in social and environmental aspects. Achieving a sustainable growth path in the long term implies “coherence” in the advancement of these three dimensions (avoiding potential imbalances threatening that path). Here the notion of “sustainable” competitiveness arises. In this context, the objective of this paper is to demonstrate, through a quantitative methodology, that the coherence of economic, social and environmental dimensions is in fact at the core of regional prosperity and regional gap. To do so, the paper analyses the systemic interdependencies between these three fields using a quantitative methodological approach: the Sustainable Equilibrium Index (SEI). The results include the overall estimates for the SEI in each Spanish region as well as a detailed decomposition of the index by economic, social and environmental fields. Finally, recommendations are made to consider SEI as a metric for the upcoming RIS3 strategies.</em></p>

Electronic commerce, marketing on line, and network economy are today’s keywords of (possible) success. But how many managers effectively know about the cost and benefits of starting to sell their products and services through the Web? How much they should invest at the beginning and how long does it takes to have a break-even point of their investment? In order to give support for better understanding the process of the Web marketing and to have more elements to decide to “dive” or not in this virtual world a System Dynamics (SD) model (Forrester J.W. 1961, 1971, 1980), has been developed. The model has the aim to support strategic decisions for SME involvement in e-Commerce, pointed out to guarantee sustainable growth and medium-long term success. The project e-Impresa1 analyses the whole process of the investment in building and maintaining a web site, taking into account the main variables of E-commerce. Through a case study, a SD business game model has been developed. The model gives the opportunity to users to evaluate different what-if analysis through the simulation period time (2 years) at each model step time (4 weeks). This chapter will explain the overall architecture of the model and will present some results of use of the model in different conditions.

AbstractVarying models of community engagement provide methods for museums to build valuable relationships with communities. These relationships hold the potential to become ongoing, dynamic opportunities for active community participation and engagement with museums. Nevertheless, the nuances of this engagement continue to remain a unique process that requires delicate balancing of museum obligations and community needs in order to ensure meaningful outcomes are achieved. This article discusses how community engagement can be an active, participatory process for visitors to museums. Research projects that utilise aspects of community-driven engagement models allow museums to encourage a sense of ownership and active participation with the museum. Indeed museums can balance obligations of education and representation of the past with long-term, meaningful community needs via projects that utilise aspects of community-driven engagement models. Using an oral history project at Historic Ormiston House as a case study,1 the article argues that museums and historic sites can encourage ongoing engagement through active community participation in museum projects. While this approach carries both challenges and opportunities for the museum, it opens doors to meaningful and long-term community engagement, allowing visitors to embrace the museum and its stories as active participants rather than as passive consumers.

One renewable energy form currently being promoted is that of biodiesel as a substitute for diesel fuel. This involves mixing biodiesel with petrodiesel in proportions governed by the respective regulations of each country. The purposes of this research are to support the exploiting of biodiesel forms of renewable energy and to optimize the palm oil-sourced biodiesel supply chain by conducting an Indonesia-based case study. The optimization process was implemented in accordance with the government's mandate and long-term planning. There are two decision variables to consider. First, the model will identify the optimum delivery point locations as a blending terminal between biodiesel and petrodiesel (petroleum diesel). Second, it will determine the location of biodiesel plants’ construction in order to satisfy the government's mandate. The results show that, while determining delivery point locations affects supply chain costs, it does not do so significantly. More influential is determining the construction locations of biodiesel plants and this study provides a model for deciding the delivery points and locations of biodiesel plants in order to minimize biodiesel supply chain costs in Indonesia. This study presents in detail biodiesel supply chain process in Indonesia and based on the literature, no research was found on studying optimization biodiesel supply chain in Indonesia.

The outbreak of the Covid-19 pandemic caused a serious impact on the business activities of enterprises and households, affecting the operation of banks around the world, especially for capital mobilization from those with savings deposits at commercial banks. In face of the unpredictable developments of the pandemic, many services of banks in Vietnam were also affected, so it has been necessary to make a plan to maintain business operations and respond effectively to these difficulties. In this study, the authors used three research models to form a three-dimensional frame of reference (past, present, and future) to identify, analyze, and evaluate the factors affecting the service quality of commercial banks’ savings deposit mobilization, and to suggest solutions that can minimize risks and improve customer satisfaction for savings deposits at commercial banks, improve service quality to avoid potential long-term risks, as well as maintain sustainable growth and social stability in the future.

Rapid Pace

With the rapid pace of urbanization in populous regions, the conflict between economic development and eco-environment becomes increasingly notable, inducing policy makers to implement new technological solutions for regional sustainable growth. Choosing the East Zhejiang region in China as a case study, this paper reveals the interaction effects between technology-driven urbanization and eco-environment, by compiling novel indexes for factors such as the degree of urbanization, environmental pressure, environmental protection, and environmental quality from 2005 to 2014, and adopting a data-intensive systemic approach. Differing from previous literature, an inverted “U” structure and panel vector autoregressive model are constructed to show that: (i) Given the acceleration of technology-driven urbanization, its surrounding eco-environment is still likely to be under greater pressure; (ii) the relationships between technology-driven urbanization and environmental factors in different regions are heterogeneous, either with a normal U-shaped curve or an inverted U-shaped curve; and (iii) the two-way interaction effects are significantly unbalanced, with long-term contribution rates of environmental quality and pressure on urbanization to be 57.8% and 78.88%, respectively, which is higher than the reversal effect. This study provides scientific reference for urban planning and advocates that more technological innovations should be implemented to help maintain sustainable urbanization processes.

In today’s volatile business arena, companies need to be resilient to deal with the unexpected. One of the main pillars of enterprise resilience is the capacity to anticipate, prevent and prepare in advance for disruptions. From this perspective, the paper proposes a mixed-integer linear programming (MILP) model for optimising preparedness capacity. Based on the proposed reference framework for enterprise resilience enhancement, the MILP optimises the activation of preventive actions to reduce proneness to disruption. To do so, the objective function minimizes the sum of the annual expected cost of disruptive events after implementing preventive actions and the annual cost of such actions. Moreover, the algorithm includes a constraint capping the investment in preventive actions and an attenuation formula to deal with the joint savings produced by the activation of two or more preventive actions on the same disruptive event. The management and business rationale for proposing the MILP approach is to keep it as simple and comprehensible as possible so that it does not require highly mathematically skilled personnel, thus allowing top managers at enterprises of any size to apply it effortlessly. Finally, a real pilot case study was performed to validate the mathematical formulation.
