This article aims to study the application of standardization techniques in a two-wheel hub company in the city of Manaus, more specifically in the subassembly sector of the chassis, responsible for the preparation of parts to supply the assembly line. The methodologies used were the 5S methodology, which is proven very effective in identifying and eliminating waste and increasing efficiency; the standardization of intermediate stock, to improve the performance of the purchasing and business sectors, and finally, the PDCA cycle, to identify needs and find suitable, low-cost solutions. From the data collected, the problem was defined as the three worst parts, which are the mudguard, rear fork, and top cover, as it was found that they are recurrent in more than 50% of the models produced. These defects are due to the improper storage of the parts, which present scratches and beat marks. The need to establish an ideal condition of ideal storage was raised, and a manual was elaborated in which basic actions are listed to avoid small defects. After applying the mentioned tools and methodologies, the company managed to reduce the occurrence of small defects.

Information about the land use of built-up areas is required for the comprehensive planning and management of cities. However, due to the high cost of the land use surveys, land use data is out-dated or not available for many cities. Therefore, we propose the reuse of up-to-date and low-cost place data from social media applications for land use mapping purposes. As main case study, we used Foursquare place data for estimating nonresidential building block use in the city of Amsterdam. Based on the Foursquare place categories, we estimated the use of 9827 building blocks, and we compared the classification results with a reference building block use dataset. Our evaluation metric is the kappa coefficient, which determines if the classification results are significantly better than a random guess result. Using the optimal set of parameter values, we achieved the highest kappa coefficient values for the land use categories “ hotels, restaurants and cafes” (0.76) and “ retail” (0.65). The lowest kappa coefficients were found for the land use categories “ industries” and “ storage and unclear”. We have also applied the methodology in another case study area, the city of Varese in Italy, where we had similar accuracy results. We therefore conclude that Foursquare place data can be trusted only for the estimation of particular land use categories.

Smart cities are an extremely important, multi-faceted subject, both in terms of their practical aspects and in terms of research. This is expressed, among other things, in the multitude of approaches to this concept. These approaches differ based on the emphasis placed on individual aspects: some focus more on technology, and others put more weight on social issues, while still others value sustainable development issues. Currently, an important topic of discussion about the development of the smart city—the importance of which has become even greater in the context of the COVID-19 pandemic—is the digital transformation of the city. The use of robotic process automation (RPA) tools can be a part of such a transformation, as such tools, using advanced software, enable the automation of those tasks carried out thus far by humans. Although such an approach has, to date, been widespread in the case of enterprises (in particular, those operating in the financial and BPO/SSC sectors, but less often in the utilities sector, the first applications of these solutions in the context of process automation for cities are also beginning to emerge in various parts of the world. This article is based on a case study approach. The implementation conditions (including the constraints) of such an approach, the benefits achieved, and the lessons learned (which can be important for other local government units) are outlined using the example of the Bydgoszcz city hall’s (Poland) electricity billing document management. The results of the case study presented here lead to the conclusion that the use of RPA tools enables, very quickly and at relatively low cost, measurable results to be achieved that are related to the processing of electricity billing documentation for the city of Bydgoszcz. This allows the assertion to be made that robotic process automation can be taken into consideration as one of the tools used to build smart cities.

Continuous improvement of productivity and quality is a potential requirement of any competitive organization. Lean six-sigma is known as the useful and popular method to do it. In this paper, a case study in the mechanical manufacturing process would be presented as a successful implementation. The seven quality control tools would be integrated in specific systematic steps of the PDCA cycle and DMAIC process, and lean technology. The case study shows the promising results on improvement of productivity and quality of a mechanical production line. It could be considered to implement for other production or assembly line in other fields such as electronic assembly line, garment line, and furnitune assembly line.

Bridgeheader is one of the typology of low-income people in the city who assume that the house is only ‘a springboard’ for their life in the city. This group of people dwelt not far from the location of their place to work; occupying marginal spaces in the city and its environment tend to be slump. Almost all areas in the city of Jakarta have marginal spaces, therefore the government attempt to improve the quality of their houses, for example by providing low-cost housing. In fact the low-cost house which was provided by the government failed to be ‘consumed’ by the brigdeheaders at the time when the used value of the house has been turned into market value. The research aimed to determine such approaches of use value of the house that can be ‘consumed’ by the brigdeheader, but did not undermine the space in the city. Data collection methods using practical observation conducted with interviews. While the analysis using descriptive pragmatic method in four case study area in Jakarta. The findings indicate that the concept of house for this group is not determined only by the ‘low price tag’ but also ‘the way of use’ of the space contributed with the result that the house can be ‘consumed’ well.

PurposeIn Brazil, the city of Pelotas experienced an economic apex between the end of the nineteenth century and the beginning of the twentieth century, reflecting in the construction of several buildings. The aim of this article is to evaluate the state of degradation of the facades of the Old School of Agronomy Eliseu Maciel, using qualitative and quantitative indicators.Design/methodology/approachThe study was divided into visual and photographic survey, damage map and subsequent application of the Degradation Measurement Method (MMD) and the Element Performance Index (Ip). Taking into consideration the evaluation of the building: through historical research and survey of damages. Finally, the building was framed at a level of degradation.FindingsBy calculating the average damage between the methods – damage map, MMD and Ip – a more faithful representation of the damage was obtained, since the values become balanced. The results show the potential of the use of the methods in the analysis of pathological manifestations in facades.Originality/valueThe originality of this article refers to the use of methods for evaluation of historical buildings. The authors believe that the methods described applied jointly provide the results about the state of degradation through nondestructive and low-cost analyses. The methods of surveying damage to Brazilian heritage are a little researched area. This work will hopefully be engaged by academics and professionals to help establish and promote broad government interest and investments.

Purpose The purpose of this paper is to establish and evaluate the concrete loss and labor productivity (LP) indicators in the concreting step of aluminum formwork system (AFS) in construction in Brazil. The loss and productivity indicators are directed to a regional database (Pernambuco, Brazil). Design/methodology/approach Case study was selected as the most appropriate approach. The methodology included data collection in the construction project with 10 residential towers of 320 apartments, in the city of Jaboatão dos Guararapes, Brazil, throughout 82 concrete pouring days using 415 concrete mixer trucks, with a total of 2,582.50 m3 of concrete. Findings The findings identified an average concrete loss of 2.6 percent and the LP indicator varying between 0.15 and 0.97 WH/m3. It could be verified that the loss indicators were influenced mainly by the learning effect associated to the qualification of the labor. In addition, the productivity indicators were strongly influenced by delays at the beginning of the concrete pouring and by problems coming from the sequence of concrete supply. Originality/value LP indicators are still literature restricted, especially considering only the concreting step. The direct observations of this study allow the identification of factors that inhibit productivity. The comparison of indicators for the concreting service between the ASF and the conventional system attests to the speed, low cost and efficiency of the system studied in this paper.

Cotonou is the largest city and main economic centre of the nation of Benin, Africa. Following independence, the city has experienced major population growth resulting in the extensive development of slums on flood plains and marshes causing the loss of biodiversity of these fragile ecosystems. Infrastructural development, unable to keep pace with informal settlement development, and a cumbersome municipal service system, have led to the illegal dumping of organic and plastic wastes, and extensive land pollution. In addition, due to its primary dune coastal location, Cotonou is facing sea level rise risks demonstrating the urgent need to sustainably address urban development. Through a socio-technical framework, this paper considers the use of transformed plastic wastes as new settlement building blocks to reduce solid waste, create jobs, and develop low-cost housing. This new strategy offers employment empowerment and a strategy to generate an income of US$2,380,000 per annum and the creation of 3200 permanent jobs.

Contraction, downsizing, rescaling and subtraction are all words that characterise the urban planning debate with increasing frequency. Two components can be found at the basis of their circulation and declination.On the one hand, the recognition of the vast unused and disused real estate for which regeneration, reuse and renovation are not possible; on the other hand, the will and hope to rebalance the results of the hypertrophic twentieth-century urban development. The legitimacy of these instances is the wides pread belief that demolition and contraction are low-cost operations that can be financed by the owners of the property or through the usual equalisation and negotiation mechanisms. By using a case study, this paper will clear up amis understanding; it will explain how demolition and subtraction costs, which can be put on equal footing with renovations and, in some cases, new construction are sufficiently massive making their implementation within the public and public-private policies very difficult.

Nowadays, digital media play a central role in a shift towards updated modes of communicating knowledge. In addition to this, the tragic recent events related to the long series of earthquakes that have taken place in central Italy have also, unfortunately, reiterated the need to document and preserve not only the material value of the architectural heritage but also the intangible values related to the events and people that have characterized their history. In this framework, the paper investigates some of the opportunities offered by technological innovations, in particular, by the specific application areas of augmented reality and augmented virtuality. The case study The historical site chosen as case study is the complex of <i>Santissima Annunziata</i>, which has played a very important role in the city of Ascoli Piceno (Italy) for centuries. <br><br> The objective was to develop a low-cost web-based platform to serve as a place to gather cultural content related to the diffuse cultural heritage, organized in applications regarding graphical and 3D models as well as 360° images and archival documents.
