An execution, monitoring and replanning approach for optimal energy management in microgrids
2011
abstract This work develops a new approach for optimal energy management of electrical distribution ‘smart-grids’. Optimality aims at improving sustainability through the minimization of carbon emissions and atreducing production costs and maximizing quality. Input data are the forecasted loads and productionsfrom renewable generation units, output data are a set of control actions for the actuators. Theconsidered electrical distribution system includes storage units that must be considered over a 24 h timeinterval, to consider an entire charge and discharge cycle. The objectives for the optimal management ofdistributed (renewables and not) generation are technical, economical and environme…
Multidiscipline LCA application to an experience of industrial symbiosis in South of Italy
2007
The paper presents an application of the Life-Cycle Assessment (LCA) to the planning and environmental management of an “eco-industrial cluster.” A feasibility study of industrial symbiosis in southern Italy is carried out, where interlinked companies share subproducts and scraps, services, structures, and plants to reduce the related environmental impact. In particular, the research focuses on new recycling solutions to create open recycling loops in which plastic subproducts and scraps are transferred to external production systems. The main environmental benefits are the reduction of resource depletion, air emissions, and landfilled wastes. The proposed strategies are also economically v…
Clean and Sustainable Biodiesel Production
2015
To date, the majority of world's primary energy is derived from fossil fuels. However, the fossil fuel recourses are in an inevitable decline as energy demand continues to grow exponentially with population growth, urbanization, and improved standards of living. Crude oil prices have recently risen several times and their current annual volatility exceeds 30%. The potential scarcity of fossil fuels has prompted a global search for alternative energy resources. Biodiesel fulfills the major requirements for production of alternative fuels such as feedstock availability, technical feasibility, and economic competitiveness. Together with other renewable biofuels, the use of biodiesel as a subst…
An exploratory study for analyzing the energy savings obtainable by reshaping processes of sheet metal based components
2017
Abstract Producing materials causes about 25% of all anthropogenic CO2 emissions. Reshaping could be one of the most efficient strategy to foster material reuse and lower the environmental impact due to material production. Sheet metal forming processes can be applied to reshape sheet metal based component. This research field is still almost unexplored and the actual environmental impact saving potential has not been quantified. The present paper aims at starting to cover this research gap, a modeling effort to quantify the environmental impact saving of reshaping is proposed. Primary energy demand for conventional recycling and reshaping are quantified and compared. Primary energy savings…
Business Process-oriented design of Enterprise Resource Planning (ERP) systems for small and medium enterprises
2006
In the last few years, many organizations have used business process modelling as an effective tool for managing organizational changes. However, process modelling has rarely been exploited for supporting the entire business process management life cycle. This includes the design of business processes as well as their implementation and control. The adoption and implementation of Enterprise Resource Planning (ERP) systems is a crucial issue if referred to small and medium-sized enterprises. The main problem is that the cost of implementation of ERP, intended as the process of customization of the ERP system towards the actual enterprise business processes, overtakes the cost of ERP acquisit…
AirBaltic Case Based Analysis of Potential for Improving Employee Engagement Levels in Latvia through Gamification
2016
Abstract In 2014, airBaltic Corporation introduced a gamified electronic platform called Forecaster with a purpose to increase its employee engagement. The article considers the approach used by the organisation, analyses results, advantages and drawbacks of the organisation, and mainly formulates recommendations for the organisation in order to improve impact on employee engagement through gamification. As a result of the research, the author proposes 8 steps that are useful and applicable to any organisation, and as such those may serve a broader purpose than just improving airBaltic Forecaster tool. The objective of the paper is to draw learnings and put forward suggestions for the organ…
Internal Quality Assurance for Higher Education Study Programme
2015
<p>Quality assurance for study programme is necessary precondition to realize qualitative higher education. Quality assessment is important part of quality assurance cycle. There are used different methodologies, assessment criteria and indicators to assess the higher education quality. It is clear that the assessment results which study programme will be better or worse are detected by the choice of criteria. It is difficult to find objective criteria which could be used universally for all study programme types. The aim of the research is to investigate quality assurance cycle for study programme quality and pay main attention to assessment part. The aim of assessment part is to sel…
Strategic Priorities and Lean Manufacturing Practices in Automotive Suppliers. Ten Years After
2011
Currently, automobile manufacturers have transformed their philosophy of production in favour of the lean manufacturing paradigm. By doing so, they hope to improve efficiency and to obtain better results in the markets in which they operate. This transformation must occur not only in their plants, but it seems important that their suppliers should also modify their production systems in line with the lean manufacturing philosophy (Liker & Wu, 2000; Morris et al., 2006; Oliver & Delbridge, 2002). The effects of this wave will probably result that one integrated supply chain can be built. Supply companies can see benefits from the implantation of lean manufacturing practices in certain of the…
Power Consumption Analysis of Operating Systems for Wireless Sensor Networks
2010
In this paper four wireless sensor network operating systems are compared in terms of power consumption. The analysis takes into account the most common operating systems-TinyOS v1.0, TinyOS v2.0, Mantis and Contiki-running on Tmote Sky and MICAz devices. With the objective of ensuring a fair evaluation, a benchmark composed of four applications has been developed, covering the most typical tasks that a Wireless Sensor Network performs. The results show the instant and average current consumption of the devices during the execution of these applications. The experimental measurements provide a good insight into the power mode in which the device components are running at every moment, and t…
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.
