Today's increasing use of Virtual Commissioning during the development process of automated manufacturing plants paired with the still increasing request towards better control program quality leads to the need of improved virtual plants with more effortless set ups. The common techniques of simulating the plant within the Virtual Commissioning do no longer fulfil these needs, new approaches have...
Industrial manufacturing processes are complex processes, where transparency of every process step is necessary to achieve a high level of quality and efficiency. In order to achieve this transparency, manufacturing execution systems (MES) are used. However, as these systems are very expensive, mainly due to individual programming effort, MES usage is oftentimes limited to larger companies. To ultimately...
Energy crisis is one of the major problems for the economic growth and development of Bangladesh. The gap between power supply and demand is increasing day after day. Moreover, most of the power plants are based on fossil fuel and have the risk of being phased out in future. This paper aims to solve these problems by balancing the power supply and demand in a smart environment, focusing mainly on...
Modern process plants are becoming more and more complex with high demands placed on design, engineering and operation. Throughout the life-cycle of process plants there is always the typical conflict involving costs, time and quality. One way of resolving this conflict is to employ simulation technology as it can be used to answer questions relating to engineering and operation earlier and with lower...
Due to the negative environmental impact of using fossil energy sources and depletion of fossil fuels, the alternative energy sources are being searched all over the world. Since wind energy is clean and renewable, the penetration of wind energy for electricity generation is increasing day by day. Wind power plants require continuous and appropriate intensity winds. In terms of the reliability and...
The increasing shares of renewable energy in power systems have a significant impact on the operation of electricity markets and grids worldwide. This paper provides an overview of the main challenges that high shares of renewable generation introduce in the power system management and electricity markets operation as well as a brief description of potential solutions for alleviating the negative...
This work in progress is a contribution to cropgrowth systems for planning and monitoring of farm activitiesand practices by farmers. The work outlines the initial findingsrelated to modelling, simulation and visualization techniques forcrop growth, specifically targeting the barley crop, such thatthe crop yield is optimized with respect to several parameters(e.g. high end user value and minimum environmental...
The research and application of data warehouse and data mining technology is the core in this paper. The design and implementation of "The productive apparel sizes and styles auxiliary decision system" is the main line. The effect of productive sizes support system is to guide the sizes quantity and enhance production efficiency based on the result of sizes compression and sales trend analysis.
The energy world is quite complex: energy is moved, stored and transformed using a heterogeneous and vastly distributed infrastructure. The move towards a cleaner and more sustainable energy system, which is favoured by people, has major implications on the energy system. Large controllable plants will be replaced by small distributed units featuring most of the time a stochastic behaviour. To accommodate...
We present dispel4py a versatile data-intensive kit presented as a standard Python library. It empowers scientists to experiment and test ideas using their familiar rapid-prototyping environment. It delivers mappings to diverse computing infrastructures, including cloud technologies, HPC architectures and specialised data-intensive machines, to move seamlessly into production with large-scale data...
A growing demand for individualized products results in an increasing number of product variations. A first step to harmonize these variations is to identify similarities between products based on their technical properties.
Real-time monitoring of the workshop is essential in improving the performance of shop floor planning, scheduling and decision making in the discrete manufacturing workshop. In this paper, a new data model is proposed with reference to the idea of spatio-temporal data. And the data structure as well as the query strategy is discussed in details. On this basis, a prototype system of holographic workshop...
With the rapid growth and the improvement of international competitiveness of Chinese economy, China's outward FDI has developed quickly, the relationship between RMB exchange rate and outward FDI has attracted more and more attentions in recent years. On the basis of constructing and analyzing the theoretical model, after method of calculation of exchange rate expectation and exchange rate volatility...
This work presents two large-scale regional models used for the evaluation of normalized power output from wind turbines and photovoltaic power plants on a European regional scale. The models give an estimate of renewable production on a regional scale with 1h resolution, starting from a mesoscale meteorological data input and taking in account the characteristics of different plants technologies...
This paper presents the MATLAB simulation framework, DiSC, for verifying voltage control approaches in power distribution systems. It consists of real consumption data, stochastic models of renewable resources, flexible assets, electrical grid, and models of the underlying communication channels. The simulation framework makes it possible to validate control approaches, and thus advance realistic...
This paper analyzes the input-output model based on data envelopment analysis (DEA), puts forward an input-output model of the vessel traffic services (VTS) based on DEA and builds the input and output index of this model combining with the demand characteristics of the running VTS' efficiency assessment. Combining with an instance of VTS, this paper analyzes the algorithm of the proposed model and...
SCGE models are ideal tool for modelling socioeconomic effects in a spatial manner. The current research is investigating this modeling methodology from the view of transportation and investigating the reciprocal cooperation possibilities with ITS systems. In this combined approach the main aims are to identify the different infrastructure and ITS development possibilities and their effects to set...
Model parameters that represent a photovoltaic (PV) system as built may not align with the original pro forma pa-rameters estimated and possibly guaranteed a priori in the pro-curement phase of a project. In this paper, the pro forma parame-ters of an existing system are revisited via on-site survey, indoor characterization, analytical modeling, and ex-post performance analysis. Moreover, the Photovoltaic...
BIPV market is growing fast and contributing to zero-energy buildings. Installing PV systems on walls is unusual, however it has a huge potential to stimulate zero-energy buildings. The production of energy from photovoltaic panels installed vertically is difficult to predict due to some reasons like the interference of shadows caused by nearby buildings or adjacent vegetation, and the lower yield...
The duration and execution of preventive maintenance (PM) activities have a significant impact on maintaining effective control over factory equipment while ensuring that it is healthy and available for production. Although most PMs in the industry have similar structures, the task of generating an automated segmented view of the PM duration and flow to highlight inefficiencies and corresponding opportunities...
