The goal of this work is to apply the idea of the city in 15 min to railway stations that can become the starting point of the analysis as they represent the “gateway”, where users start their last mile of travel after getting off the train. Within the research, 11 railway stations located in the Lombardy Region in Italy were identified and analyzed. To perform the analysis, an analytical index was implemented and determined for each station: this index summarizes the main features of the station itself in relation to the territory in which it is located. The adopted approach is comparative: it is not important the absolute value of the index of each station, but the comparison between the different indices. In this way it is possible on the one hand to classify the stations and on the other hand to identify and propose possible interventions to improve the role of a railway station in a territory. The proposed model is expandable and replicable: it is possible to add other useful indicators for the calculation of the index of each station and it is also possible to perform the analysis in different territorial contexts. In fact, it is a decision support tool able to provide indications and information for the planning and programming of the railway system and of the city; among the potential users of the proposed model there are railway station managers and administrations.

Railway stations are usually considered to be one of the main gathering centers of the city; thus, in the event of any incident, there will be significant casualties. The purpose of this study is to simulate strategies for reducing the evacuation time of the railway station in the event of fire using a safe zone approach with simulation software. To reduce the evacuation time, 18 scenarios were introduced and simulated according to (1) number of gates and exit doors, (2) width of the gates, (3) obstacles, (4) priority of the exit doors, and (5) safe zone. The results show that the best evacuation time occurs by increasing the number of exit doors from two to four and considering a safe zone simultaneously; the evacuation time is reduced by 7 min and 19 s. Using safe zones for emergency evacuation has a significant role in reducing evacuation time and improving service levels. Interestingly, the removal of gates and obstacles would increase the evacuation time of passengers. The proposed model could be used for renovating existing railway stations to decrease the consequences of accidents such as fire.

Green areas in urban agglomerations are strategic resource for the sustainable city development. The implementation of Urban Forestry Projects (UFP) allows on the one hand to raise the environmental quality level, improving the microclimate and preserving biodiversity, on the other hand to promote urban regeneration and promote socio-economic development by creating eco-systemic s er vices for the population. The result is a more rational land use and an increase in real estate values. Although the EU Directives show the need to promote the sustainable territory growth through the recover y and redevelopment of the built environment, the implementation of investments based on eco-system logic is rarely counted as a priority action for the city, often preferring a different allocation of available resources. The present work aims first to define an indicators set useful to express the value components – financial, social, cultural and ecological- environmental – for the UFP. These indicator s are the reference terms for the characterization of an innovative protocol of multicriteria analysis for the public operator who wants to establish the optimal distribution of funds between UFP units in limited areas of the urban fabric. The protocol uses the algorithms of mathematical programming and is tested on a case study about urban areas to be redeveloped.

The Shit Flow Diagram (SFD) graphic is an advocacy tool that aims to assist technical and non-technical stakeholders to implement plans and programs related to urban sanitation. The SFD methodology is increasingly being used to analyze the extent of safely managed sanitation in urban areas, providing a valuable picture of the prevailing sanitation conditions, from containment to disposal. As such, it is a widely recognized advocacy and decision support tool that aims to understand, communicate, and visualize how wastewater and fecal sludge move within a city or town. As stated on the SuSanA website, the SFD methodology offers “a new and innovative way to engage sanitation experts, political leaders, and civil society in coordinated discussions about excreta management in their city”. The production and publication of an SFD report for Cap-Haitien (Haiti) would help to visualize the current sanitation situation in the city, resulting in a potential to shift current activities and efforts towards more efficient investments in the places along the sanitation chain that need more attention, improving the urban sanitation situation and the surrounding environment of the city. The structure of this SFD report consists of an executive summary and the SFD report. The latter includes: i) general city information describing its main characteristics; ii) sanitation service outcomes, with a thorough explanation of the SFD graphic outcome and the assumptions made; iii) the service delivery context analysis, which contains information on the regulatory framework of water and sanitation at country and city levels, and describes the city plans, budget and future projects to improve the sanitation situation and; iv) a detailed description of the surveys, Key Informant Interviews (KIIs) and Focus Group Discussions (FGDs) conducted, as well as the key stakeholders involved, field visits carried out and references used to develop this SFD report.

The interest of companies for a greater valuation of their information, knowledge and competency is increasing. These companies have a knowledge capital (tacit and explicit) often poorly exploited. These information resources include knowledge and information useful and necessary to the execution of trades' processes and that it will be captured and formalized by using knowledge engineering methods, such as knowledge mapping techniques. In this context, the authors present a new approach to dynamic fusion of knowledge maps for an activities process that builds on the one hand, the graphical representation of the knowledge mapping and the boolean modelling of the graph (MBG). On the other hand, the authors' fusion algorithm of the maps which relies on notions of “index” type which allows determines the type of node of map to merge their fusion algorithm of the maps which relies on notions of “index” type which allows determines the type of node to merge and on notions of the boolean modelling of the knowledge maps. The authors finally implemented this algorithm to obtain experimental results. This result can be used as a decision support tool, whether individual or collective.

The objective of this study is to conduct an investigation about architectural heritage of Presidente Prudente. The study approaches about the building of the railway station from the 1940s, features art-deco and protomoderno, which still remains in the city space.The first building was inaugurated in 1926 and it had to be demolished, because, a newstation, bigger and more modern building would be built at the same place; it was inaugurated in 1944. Disabling the railway in Brazil generated the abandonment and/or changed the functionality of the railway stations.;in the case of Presidente Prudente it has housed the Procon Foundation and SEMST, whose building has undergone modifications and changes to accord new uses. Therefore, the research developed the inventory of the Railway Station ranging from historical documentation, photographic surveys, architectural-metric and also the diagnosis of their current condition.

The use of Remaining Useful Life (RUL) predictions as a decision support tool has increased in recent years. The RUL predictions can be obtained from Prognostics and Health Management (PHM) systems that monitor the health status and estimate the failure instant of components and systems. An example of a decision-making problem that can benet from RUL predictions is the load distribution problem, which is a common problem that appears in many industrial applications. It consists in dening how to distribute a task among a set of components. In this paper, a model to solve load distribution optimization problems is proposed. The proposed model considers the RUL prediction of each component in its formulation. Also, the proposed model assumes that the predicted RUL of each component is a function of the load assigned to that component. Thus, it is possible to distribute the load to avoid multiplecomponents to fail in a short interval. An approach based on the MMKP (Multiple-choice Multidimensional Knapsack Problem) is adopted. The proposed model nds a load distribution that minimizes the operational cost subject to a maintenance personnel capacity constraint, i.e. there is a maximum number of components that can be simultaneously on repair. A numerical case study considering a gas compressor station is presented to illustrate the application of theproposed model.

The need for renewal of disused urban area is widespread in many context of south Italy where the lack of public funds make difficult the management and maintenance of sites that often have considerable historical and architecture values.The choice of functions that can represent elements of attraction for the economic and social regeneration of these disused sites is a complex problem, given the multiplicity of interests involved and the uncertain factor determined by the non-typical conditions of real estate market, both from the demand and the supply side.In the present paper we propose to implement a choice model, based on the integration of multicriteria analysis and random utility model (referred to McFadden theory), able to support a participatory decision process of selecting alternative scenarios of requalification of an urban disused area located in a small village near the city of Naples, in the south of Italy.The positive results obtained show that the model proposed can be a useful decision support tool in environments characterized by high complexity, where the objective is precisely to highlight the elements that influence the dynamics of choice for building shared “bottom up” development strategies.

Abstract. A web-based multi-criteria decision support tool is designed to support the planning, control and deployment of building-integrated photovoltaic (BIPV) in the City of Cape Town, South Africa. Solar energy is one of the renewable sources for generating electricity by means of photovoltaic systems, and it offers a viable and expedient means of generating electricity within a short period of time. Nevertheless, there are some impediments to the extensive deployment of solar photovoltaic systems. The most prominent among these are generation potential and the high capital cost of initial set-up. Hence, the location, design and yield of building-integrated photovoltaic systems have to be well thought-out before their deployment. The interactive web-based tool designed utilises JavaScript and Hypertext Mark-up Language (HTML) to implement a map mashup, which can be queried to retrieve vital information about the solar photovoltaic potential of a building roof. From results generated and the system developed, it becomes possible to remotely and sufficiently evaluate buildings in the city in order to make decisions about solar photovoltaic potentials, designs and installations.

<p><strong>Abstract.</strong> We present a decision suppport tool for the comparison and selection of projects of integrated renovation of derelict buildings and areas for the purpose of urban regeneration. Each project is defined as a subset of derelict properties to renovate together with their respective designated use, and is scored by the decision support tool on two criteria: expected effort and estimated effectiveness in terms of improved urban capabilities in the urban area of interest. The expected effort is estimated as a global transformation cost, factoring in legal and management overhead costs as well as possible economies of scale. The effectiveness in evaluated in terms of extension of urban capabilities centred on walkable distances. We have implemented a bi-objective evolutionary search algorithm to address the computational complexity of the problem of search for efficient (non-dominated) projects over the two criteria. For the purpose of illustration, we present an example case-study application on the historical core of the city of Sassari, Italy.</p>

On 24 August 79 CE the eruption of Mount Vesuvius destroyed the southern Bay of Naples, burying the towns of Pompeii, Herculaneum, and Stabia together with the farms, sanctuaries, and luxury villas of the countryside. Their systematic excavation began in 1748. A community of scholars and lay people have since investigated the cities and their architecture for over 270 years. Their ranks are varied, starting with art and architectural historians, classicists, classical archaeologists, humanists, and amateurs, and continuing with scientists specialized in disciplines as varied as chemistry, biology, and forensics to name a few. The study of Pompeii and the ancient cities on the Bay of Naples is almost its own discipline that has helped to germinate art history and archaeology and spark movements such as Neoclassicism. The result is a burgeoning bibliography that exceeds 20,000 entries, with dozens of books and articles appearing each year. Given the rich architectural remains of the city, many, if not most, of these publications relate to architecture. Yet much remains unknown and considerable research on the architecture of Pompeii awaits current and future scholars. This article constitutes a basic starting point to study the architecture of Pompeii. It focuses on primary sources and monographs, and extends beyond single architectural studies because the study of Pompeian architecture requires attention to external factors governing social behavior. Domestic rituals, religious practices, technological advances, social routines, social hierarchy as well as military, entertainment, economic, environmental, and political factors all came together to shape the city. Modern research in Pompeii began with art historical and epigraphic approaches producing catalogues and publications describing wall painting, inscriptions, statuary, and the objects of the decorative arts. Expansive topographical surveys describing the city’s architecture started to appear in the 19th century and gave rise to a fascination with Pompeii throughout Europe. The expansion of the excavations in this period prompted then superintendent Giuseppe Fiorelli to organize the city into regions, insulae (city blocks), and house numbers, giving buildings the addresses they have today (e.g. VI.12.2-7 for the House of the Faun). Excavations seeking to understand the long-term history of Pompeii began in the 20th century, first, under efforts by Superintendent Amedeo Maiuri and, later, by various international teams and individual scholars, leading to the comprehensive approaches that study the city today. These efforts have produced a consensus that divides the 700+ years of Pompeian history into three mains phases: Pre-Samnite (under Etruscan, Greek, and Punic influence), Samnite, and finally Roman Pompeii, which subdivides further into the Colonial, Imperial, and Post-earthquake (after 62 CE) periods. Each phase is rich and stimulating in its own right, but the Roman period is the one that produced much of the architecture visible today; consequently, it has received the most attention due to the state of preservation.
