Safety valuation methods at urban atypical intersections. Analysis of infrastructural scenarios
2007
The definition of decision support tools for identifying ex ante evaluation issues for road safety measures is a new challenge for policymakers and designers managing road networks with the intention of improving traffic safety for roads of their competence. This is consistent with explicit strategies on sustainability in the transport sector established at European level, considering road safety as an essential prerequisite to warrant a sustainable mobility. Based on these considerations, the need for evaluation instruments of safety conditions both for existing infrastructural schemes and for new road installations is recently arisen so that the identification of risks involved in a parti…
Lean design improves both health-care facilities and processes: a literature review
2014
This article presents a literature review of the challenges and possibilities for Lean design in modern health-care facilities. Many of today's health-care facilities are in dire need of renovation since limited financial resources among health-care demand improved work process efficiency, safety and employee well-being. Lean philosophy has been successfully implemented into hospitals with up-and-running hospital processes, but has not been thoroughly tested as a design methodology. The principles of Lean do not contradict with user-centric, participatory or ergonomic design approaches and thus the possibilities of using Lean as a complementary design methodology to the aforementioned appro…
Warehouse threats and loss prevention management in case of fire
2016
Abstract Warehouses play an important role when it comes to the reception, delivery and storage of various types of goods. Due to the complex scenarios that may occur, as well as the heterogeneous nature of goods, warehouses bear a higher risk of accidents. Regardless if we’re taking about removing hassle or standardizing operations we speak the same language: insuring efficiency and increased efficiency leads to smart cost maintenances. In the article hear by we will observe the behavior of different warehouse materials in the case of trigger fired. Starting from the results obtained during the low scale tests and completing the premises with the large scale experiment (warehouse scale), w…
IT Technology Implications Analysis on the Occupational Risk: Cloud Computing Architecture
2014
Abstract The present paper is divided into three major areas: the analysis of occupational risk implications at national and international level, the European priorities in terms of occupational risk and the existing cloud computing services. Since human resource is present within each organization, it is required a comprehensive and actual assessment of the processes in which they participate. Like in any daily activity, processes and people contribute to the emergence of risks. If each organization creates healthy and safe workplaces that means that it contributes to the sustainable development of the area in which it operates. It can be said that occupational risk assessment and occupati…
The Complexity of Risk and Uncertainty Assessment
2017
Abstract Risk reduction means diminishing uncertainties and strengthening the knowledge. There are many ways in which undesirable surprises can be understood and controlled, but the dominating one is the risk approach, on the basis of risk conceptualization, evaluation and risk management. Across time, many progresses have been accomplished in the field of risk, connected not only to the conceptual part, but also to the empirical procedures. Despite this, the premise of this domain is being represented to a substantial extend by theories and practices. This is why it is indispensable to search for trends in the risk framework, to reveal whether further development should be desired and if u…
Technical assessment and evaluation of environmental models and software: Letter to the Editor
2011
International audience; This letter details the collective views of a number of independent researchers on the technical assessment and evaluation of environmental models and software. The purpose is to stimulate debate and initiate action that leads to an improved quality of model development and evaluation, so increasing the capacity for models to have positive outcomes from their use. As such, we emphasize the relationship between the model evaluation process and credibility with stakeholders (including funding agencies) with a view to ensure continued support for modelling efforts. Many journals, including EM&S, publish the results of environmental modelling studies and must judge the w…
The social responsibility of environmental analysis
2014
Abstract A literature updated has been made on the academical studies focused on the social impact of environmental studies, paying attention to both, the quality of the information provided and the side effects of the methodology employed, also considering the importance of the analytical methodologies in the development of remediation processes and the key subject of the transmission of the environmental information to the policy makers and the general society.
FUZZY RISK ANALYSIS OF A MODERN γ-RAY INDUSTRIAL IRRADIATOR
2011
Fuzzy fault tree analyses were used to investigate accident scenarios that involve radiological exposure to operators working in industrial γ-ray irradiation facilities. The HEART method, a first generation human reliability analysis method, was used to evaluate the probability of adverse human error in these analyses. This technique was modified on the basis of fuzzy set theory to more directly take into account the uncertainties in the error-promoting factors on which the methodology is based. Moreover, with regard to some identified accident scenarios, fuzzy radiological exposure risk, expressed in terms of potential annual death, was evaluated. The calculated fuzzy risks for the examine…
Handling the epistemic uncertainty in the selective maintenance problem
2020
Abstract Nowadays, both continuous and discontinuous operating systems require higher and higher reliability levels in order to avoid the occurrence of dangerous or even disastrous consequences. Accordingly, the definition of appropriate maintenance policies and the identification of components to be maintained during the planned system’s downtimes are fundamental to ensure the reliability maximization. Therefore, the present paper proposes a mathematical programming formulation of the selective maintenance problem with the aim to maximize the system’s reliability under an uncertain environment. Specifically, the aleatory model related to the components’ failure process is well known, where…
Back-Propagation Artificial Neural Network for ERP Adoption Cost Estimation
2011
Published version of a chapter in the book: Enterprise information systems, vol 220, part 2, 180-187. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-24355-4_19 Small and medium size enterprises (SMEs) are greatly affected by cost escalations and overruns Reliable cost factors estimation and management is a key for the success of Enterprise Resource Planning (ERP) systems adoptions in enterprises generally and SMEs specifically. This research area is still immature and needs a considerable amount of research to seek solid and realistic cost factors estimation. Majority of research in this area targets the enhancement of estimates calculated by COCOMO family models.…
