Development of a conceptual model of sustainable building from a university
2021
Introduction: In this paper, the authors aim is to develop a conceptual model that aims to facilitate the processes of implementing sustainability and / or assessment of sustainable performance in a Higher Education Building (HEB). The conceptual model could also be used to compare two or more buildings of higher education in terms of sustainability. Methodology: The authors started the scientific research with the literature review in order to identify and analyze the most relevant aspects that are frequently assess and could influencing the components of sustainability in higher education institutions. These aspects were clustered into categories and for each of them were established obje…
Statistical learning and multiple linear regression model for network selection using MIH
2014
Award of Appreciation; International audience; A key requirement to provide seamless mobility and guaranteeing Quality of Service in heterogeneous environment is to select the best destination network during handover. In this paper, we propose a new schema for network selection based on Multiple Linear Regression Model (MLRM). A horough investigation, on a huge live data collected from GPRS/UMTS networks led to identify the Key Performance Indicators (KPIs) that play the most important role in the handover process. These KPIs are: Received Signal Code Power (RSCP), received energy per chip (Ec/No) and Available Bandwidth (ABW) of the destination network. To extract a handover model from col…
Improving membrane photobioreactor performance by reducing light path: operating conditions and key performance indicators
2020
[EN] Microalgae cultivation has been receiving increasing interest in wastewater remediation due to their ability to assimilate nutrients present in wastewater streams. In this respect, cultivating microalgae in membrane photobioreactors (MPBRs) allows decoupling the solid retention time (SRT) from the hydraulic retention time (HRT), which enables to increase the nutrient load to the photobioreactors (PBRs) while avoiding the wash out of the microalgae biomass. The reduction of the PBR light path from 25 to 10 cm increased the nitrogen and phosphorus recovery rates, microalgae biomass productivity and photosynthetic efficiency by 150, 103, 194 and 67%, respectively.The areal biomass product…
Assessing the efficiency of wastewater treatment plants in an uncertain context: a DEA with tolerances approach
2012
Abstract As the number of wastewater treatment plants (WWTPs) has increased, the economics associated with their management have become more relevant. The efficiency assessment is therefore a useful tool for cost reduction. For this purpose, Data Envelopment Analysis (DEA) is a highly suitable technique, since it is a holistic approach that aggregates performance indicators into a single index. However, one of the most common criticisms of DEA models is that information on uncertainty estimates is not provided. To overcome this limitation, we assess efficiency by using a DEA model with statistical tolerances for both inputs and outputs. This model is applied to a sample of Spanish WWTPs. Th…
Dealing with Multi-Level Governance and Wicked Problems in Urban Transportation Systems: The Case of Palermo Municipality
2015
Italian New Public Management (NPM) has been mainly characterized by a political orientation toward power decentralization to local governments and privatization of public companies. Nowadays, local utilities in Italy are often run by joint stock companies controlled by public agencies such as Regional and Municipal Administrations. Due to this transformation, these companies must comply with a set of diverse expectations coming from a wide range of stakeholders, related to their financial, competitive and social performance. Such fragmented governance increases the presence of “wicked” problems in the decision-making sphere of these entities. Given this multi-level governance structure, ho…
Conflicting interests but filtered key targets: Stakeholder and resource-dependency analyses at a University of Applied Sciences
2013
Stakeholder theory (SHT) emphasizes that different stakeholders and their interests need to be identified and addressed to maximize firm performance. This emphasis can make the design of performance measurement systems (PMS) challenging because the interests of stakeholders are often in conflict. Based on previous research and using stakeholder and resource dependency theories, we develop a theoretical model suggesting that resource dependency acts as a “filter” in selecting which of the PMS design measures are emphasized for decision making. We find various conflicting interests between stakeholders in our case organization (a unit of University of Applied Sciences in Finland) that affecte…
The impact of training andad hocteams in industrial settings
2006
This paper aims to reflect the use of training via ad hoc teams to adopt lean production practices. In our research, eleven automobile manufacturer suppliers implement training interventions to achieve better results through lean production, concluding that training helps companies to develop lean production systems and to improve performance indicators.
Vers une tridimensionalité du contrôle interactif
2011
We propose in this paper to revisit the concept of interactive control, highlighted by Robert Simons, examining the use of "environmental control systems" in Ten French Companies proactive in ecology. By showing that interactivity of "control systems" is not limited to a vertical dimension as suggested by Simons, but it tends towards three-dimensional (vertical, transversal and external), this study highlights the interest of explore further upstream the concept of interactive control little studied in the literature.
Combined fuzzy TOPSIS and AHP-based methodology for the prioritization of maintenance key performance indicators: Application to an oil refinery plant
2017
A Maintenance Performance Measurement model based on the use of Maintenance Key Performance Indicators (MKPIs) is proposed in the present paper. Referring to a specific industrial context, a multi-level hierarchical structure is firstly designed to highlight the most meaningful perspectives which affect the maintenance performance. Then, MKPIs selected from the literature or properly formulated to detail some particular perspective of the investigated maintenance process are assigned to the hierarchical framework and prioritized by a Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) and Analytic Hierarchy Process (AHP)-based approach.
Communication Gaps in Disaster Management: Perceptions by Experts from Governmental and Non-Governmental Organizations
2011
The complexity of current disasters creates a challenge for crisis communication. This paper aims at identifying gaps in communication in disaster management experienced in practice in order to facilitate learning from those situations. The research was conducted using a qualitative online open-ended questionnaire. It shows that despite the developments in the discipline, communication as an integral part of decision making in disaster management needs to be further developed. The paper provides a practical-oriented overview of the communication constraints in complex crisis situations, which has not been provided so far. This research is part of an international project developing performa…
