Every link of power system may exist security risks, power industry funds and technology is highly concentrated, the production equipment is very expensive, its operating parameters almost reached the extreme, physical simulation of its production process of experimental teaching costs are extremely high, resource consumption is huge, and may cause malignant environmental pollution. Teaching, training...
Modularization is considered as one enabler for flexible and highly reconfigurable process plants. These characteristics are needed to overcome deficiencies regarding market volatility and shorter product innovation cycles. Current standardization activities aim at the specification of Module Type Package (MTP) files as a semantic description of modules for fast and efficient integration into process...
The current upward trend of the residential energy demand and the high penetration of new renewable resources have changed the conception of the electrical grid. The centralized distribution scheme is currently moving forward to a distributed layout where the paradigm of Smart Energy Communities has emerged, meaning a set of households that share a Microgrid, have tied renewable production and can...
Based on unified data expression model of agricultural data lacking with the common management data, and inconsistent problems of agricultural data in the process of the management and use, the establishing method of the agricultural data integration model based on ontology is presented in this paper. First, the common management data structure of agricultural production institutions is analyzed,...
In this paper, the trailing suction hopper dredger dredging production is used to be an optimization objective. By analyzing the impacts of dredging operation behaviors and system uptime factors, an artificial neural network algorithm for parameter optimization of dredging operations is proposed. Based on the field construction parameters of the trailing suction hopper dredger, the method integrates...
Effective model-driven engineering of complex systems requires to appropriately describe different specific system aspects. To this end, efficient integration of different heterogeneous modeling languages is essential. Modeling language integaration is onerous and requires in-depth conceptual and technical knowledge and effort. Traditional modeling lanugage integration approches require language engineers...
The design of an operator-training computer simulator for chemical processes is very important in the process control and simulation area. In this paper, an operator-training simulator is developed for a small-scale fine chemical production process using an IPC (industrial personal computer and intelligent process controller) simulation mode and a typical SCADA (supervisory control and data acquisition)...
The paper focuses on development and application of a software engineering system BPsim.SD, part of decision support suite BPsim.DSS, which greatly simplifies analysts work and their interaction with software developers. System is integrated into a decision support suite, which allows instant transition from software entities design to simulation of developed product with possible application of simulation...
To meet the increasing requirements of sustainable production and to assure economic competitiveness, novel strategic approaches are necessary in designing production systems and to increase energy efficiency in the manufacturing industry. Individual areas within production facilities (e.g. production system, energy system, building hull) can be analyzed individually by using simulation-based methods...
In oil field enterprise, the spatial information including the geographic information, property data of spatial object and digital cartography are stored and managed dividedly. A integrated data model is put forward to express and manage spatial information. Epicentre, a integrated standard data model, is introduced at first. Based on Epicentre model, the architecture of integrated spatial data model...
Service oriented architecture (SOA) is nowadays one of the dominant styles in developing new information systems. These information systems often have complex models, which can contain mistakes, or are described by informally. In order to minimize mistakes and to create formal models, patterns as components of software development could be used — according to Model driven development (MDD) principles...
Abstract-This article describes the modeling and design ideas of system optimization. It takes the production line of a car factory in Chongqing for example. According to the production management and simulation theory, we use the simulation software Flexsim to establish the model of painting's key process and use it to analyse the existing congestion bottlenecks of tools, proposing two optimization...
This paper first analyzed the technical background and the realistic demand of the web-based system of product customization and simulation. And then, the overall system structure and the work process were proposed, analysis and statement of the essential technology was proposed. Based on the research, a web-based system of product customization and simulation was developed primarily in JSP, and a...
The Disaster Response Network Enabled Platform (DRNEP) is a system that integrates a set of independently developed infrastructure and disaster simulators. This paper describes some of the architectural choices that we made for DRNEP. The overall system uses a master-slave pattern, with one master simulator orchestrating all of the others, based on a central system clock. As the various simulators...
In order to meet the complicated data connection between multi businesses, to meet the original business change on structure and application, to meet the multi-user management, we designed the unified database model of user-defined businesses based on those concepts of Business, ManageClass, Indice, Indice_Group, User, Instance and so on. This paper introduces the object-oriented database modeling...
In the automotive industry an integrated set of manufacturing engineering activities lie on the critical path of the Vehicle Development Process (VDP). After the product integration design is finalized, the Production Tool Design and Build (PTDB) processes becomes the VDP critical path. It is in the PTDB where virtual launch and validation activities are performed. To increase throughput of the engineering...
This paper addressed extending quality data in lot-based traceability information system through modeling and evaluation which is purposely designed for small-to-medium size enterprise (SMEs). The solution translates the system behavior and value data arisen from traceability requirement into useful and organized computerized information system. Easy-understanding and economic approach in design and...
Virtual reality (VR) project workflow is the core and main subject of VR project management and the management of the workflow is the key factor for the smooth progress of the project and the most effective way to improve efficiency of the project. Based on the current status of VR management in China, this paper has formulated a standard VR project workflow featuring universality and generality,...
Collaborative Manufacturing Business System is a new application model based on workflow technology, this paper establishes process model on the basis of analyzing the characteristics of collaborative manufacturing business, and then gives a framework structure for it and implementation techniques, in addition to the heterogeneous data solution.
This paper focuses on data modeling for traceability in information layer of manufacturing control system. The model is able to trace all associated data throughout the product manufacturing from order to final product. Applicability of designed data-model is enhanced with traceability of associated quality data for the system dynamically. The modeling consisted of four steps, mapped successfully...
