Implementation of walk-through audits for designing energy management system: A first step towards an efficient campus
2020
Abstract The purpose of this study is to design a concept of energy management control system (EMCS) at the UNSADA campus, Jakarta, Indonesia by utilizing the results of the previous walkthrough audit. EMCS is an important first step by involving all parties on campus to be concerned the sustainable energy savings. The energy efficiency program utilizes the campus as an energy laboratory to identify, recommend, implement and evaluate the energy consumption, so that the expected energy efficiency targeted by the top managements can be achieved. This program is motivated by several reasons, such as; to support government policies in reducing dependence on fossil energy by implementing energy …
Virtual/Digital and Internet-based Machining
2008
This chapter provides comprehensive knowledge regarding the application of various virtual digital and information techniques to machining processes and machine tools, and their simulation and visualization. A number of manufacturing concepts used in modern industry, such as Internet-based manufacturing, digital manufacturing, virtual manufacturing and telemanufacturing, are characterized. In particular, architectures of digital manufacturing and virtual manufacturing, along with their practical applications, are presented. The architecture of the virtual machine tool and numerous examples of simulations of machining process performing on multi-axis/multitasking are visualized. Moreover, vi…
VISOCAR: an autonomous industrial transport vehicle guided by visual navigation
2003
The authors describe a vision system, called VISOCAR, for mobile robot guidance in industrial environments. VISOCAR is an optically navigating AGV (automatically guided vehicle) that, owing to its local intelligence, can travel automatically in its natural environment, does not need any dedicated floor installations, and does not impose any restrictions on the route network or factory environment. It can navigate accurately on its track and integrate multisensor information to enhance functional redundancy and system reliability. It is shown that the navigation task can be broken down into a hierarchy of goals, which can be attained by functionally independent modules. The system architectu…
Consideration Regarding the Configuration of the Resources and Modeling the Manufacturing Work Cell
2015
This paper is presented the concept of developing a generic reference architecture model for the specification, development, control and reconfiguration of a manufacturing enterprise at a work cell level. It is described a generic system architecture for FMS; there is also briefly explained how to configure the different resource modules that actually control the tasks of the physical device and put together a work cell consisting of other FMS resources. Using the principles of distributed object technology there could be implemented each resource in the work cell as a distributed object. Finally, an example on building a FMS using a hierarchical approach is presented.
Towards more equity concerning quality of Urban Waste Management services in the context of cities
2018
Abstract An innovative combined evaluation approach is proposed in the present paper to deal with the issue of the performance measurement and comparison of Urban Waste Management (UWM) services in the context of cities. The ELECTRE III method is initially considered as tool able to execute a multi-criteria analysis aimed at ranking UWM systems based on their integration and sustainability levels. The latter are comprehensively evaluated via the recently developed “Wasteaware” Integrated and Sustainability Waste Management indicators framework, which takes into account physical components and governance aspects of UWM systems. Then, on the basis on ELECTRE III results, a practical gaps inve…
Sustainable mobility: “exchange poles” between transport networks and urban structure
2012
An intermodal hub can be defined as a place where transportation networks are organized to facilitate intermodality between different modes. Intermodal hubs should intrinsically have an urban dimension and be globally designed as “plug flows”, being interfaces between transport networks and territory, being an element to create “urbanity”. Intermodal hubs focus technical, social, urban, transport, service aspects and they play a multi-modal, multi-service, multioperator role. Several studies highlight the need to “measure the interdependence” among the various aspects of urban problems, avoiding too specific methodologies. The increasing congestion in urban centres and urban parking problem…
An optimized diagnostic architecture for real-time monitoring of MV networks
2006
Due to the electrical energy market liberalization, the Authority for electrical energy and gas (AEEG) in Italy and the other regulatory organizations in other European countries have concentrated their attention on the quality of the electrical service. One of the aspect of major importance in the definition of the quality of a public service is its continuity. In the aim of regulating this field the Authority has defined some continuity indicators, for example the number of interruptions per year and the cumulate duration of the interruptions per year. Recent statistics on these indicator show that the 80% of the number of interruptions in one year is caused by MV network. For this reason…
Sensor-Assisted Machining
2008
This chapter provides comprehensive knowledge regarding the application of various sensors and monitoring techniques to machining processes, cutting tools and machine tools. A number of monitoring methods used in manufacturing and relevant sensors are characterized. In particular, three most frequently used sensors, i.e., force, acceleration and acoustic emission, are presented and their characteristics and advantages are highlighted. The architectures of multiple-sensor tool-monitoring systems for detection of tool wear and breakage and collision for machine tools, including details of sensor fusion, signal processing and decision-making, are presented. Moreover, the concepts of sensor-bas…
<title>Architecture for real-time wood inspection</title>
2000
This study has been realized to improve industrial machines that allow to analyze planks by detecting their width and too important defects thanks to a computer vision system. These machines are currently piloted by software with the help of PCs. The aim of our work is to realize a hardware card to increase the processing speed.
Business architecture development at public administration - Insights from government EA method engineering project in Finland
2008
Governments worldwide are concerned for efficient production of services to customers. To improve quality of services and to make service production more efficient, information and communication technology (ICT) is largely exploited in public administration (PA). Succeeding in this exploitation calls for large-scale planning which embraces issues from strategic to technological level. In this planning the notion of enterprise architecture (EA) is commonly applied. One of the sub-architectures of EA is business architecture (BA). BA planning is challenging in PA due to a large number of stakeholders, a wide set of customers, and solid and hierarchical structures of organizations. To support …
