The accurate prediction of the buildtime required is also critical for various activities such as: the job quoting, the job scheduling, the selection of build parameters (. layer thickness and orientation), benchmarking, etc. Two buildtime estimators based on sliced process and STL have been exploited, respectively. Ref. [40] presents the principle of a buildtime estimation algorithm for Stereolithograpy based on model geometrical features. After clients accept initially the quote, they may negotiate with SB on the business and technological details. The Microsoft NetMeeting which can set up a collaborative environment to fulfill information 12 sharing, file transferring, Video and Audio munication etc., provides an ideal tool for the online negotiation. It is also seamlessly integrated IE Browser, thus clients can call SB at any moment. As a result of negotiation, an electronic contract is to be signed. To effectively manage andoperate these electronic contracts, the system alsoprovides a contract management ponent. It is especially convenient and prompt for clients to submit, inquire, and search contract through this module. The manufacturing service module which covers the job management, collaborative manufacturing, process monitor, and collaborative enterprises management, is regarded as one of the most important function modules in the service system. When a contract is confirmed, clients will formally submit their job requirements (. RE, 3D CAD modelling, CAE, RP prototype, or rapid tooling) and sources (. object parts, digitized data cloud, 2D models, 3D models, or .STL files). In order to help many novices submit quickly and easy the manufacturing tasks, various job and source templates have been created, while the client can search, modify, and even delete the manufacturing tasks itself if the occasion arises. The Collaborative Manufacturing System (CMS) is responsible for the selection of collaborative enterprises (CE). In addition, it is extraordinarily important and necessary to monitor the manufacturing schedule and control product quality to ensure smooth production. In the past, a SB had to spend much time on dealing with a lot of inquires from the clients by via phone calls or Faxes. Now, the Process Monitor System (PMS) provides various facilities which canguarantee the tasks to be pleted timely. Any partners falling behind schedule or failing to meet quality standards will be closely examined by SB and users to ensure that precautionary or remedial measures are made ahead of time or any damaging effects are predicted. All information (no matter if it is a real client being ready for a contract with the SB or just a potential one showing his intent or inquiry) involved in the whole service process are managed and maintained by a special Database. These data provide strong supports for both online business and manufacturing service. 13 To create a collaborative environment among SB, users and CE, we have to rely fully on the multimedia and Inter. Therefore, the service system offers three enabling tools: Video conferencing system, Electronic whiteboarding, and FTP. In order to make use of the system as quickly as possible, users can get help from the system navigation module. These nine ponents form a fullyintegrated system that is able to carry out tasks in an efficient and effective way. On the basis of the workflow and function module of service system, the system framework can be constructed as shown in Fig. 4. Fig. 5 illustrates the worked structure of service system. 5. Configuration of running platform In order to run this system effectively, constructing asuitable running platform is necessary and especially crucial. An operating system (OS) is one of the most basic software ponents for running this system. The operating systems monly founded onWeb Servers are UNIX, OS, Linux, and Windows, etc. Windows 2021 Advanced Server is a better platform for running business application. Better SMP scalability, improved working performance, and support for more physical memory have a profound impact on the performance of Windows 2021 Advanced Server in an application server environment. Hence, we select Windows 2021 Advanced Server as the operating systemof the running platform. Web Servers including Apache, IIS, iPla, CERN, and IBM WebSphere, are frequently installed websites at the present time. Inter Information Services (IIS) which is integratedWindows Advanced 2021 Server is a new release Web Server of Microsoft Company. Not only being a Server, it also provides a number of other Inter services such as FTP, News, WWW, and SMTP, etc. With tighter integration between the operating system and IIS, it offers performance gains and higher availability for Web Servers and sites. Normally IIS can not execute Servlet and Java Server Pages (JSP), configuring IIS to use Tomcat redirector plugin will let IIS send Servlet, and JSP requests to Tomcat (and thisway, serve them to clients). of the Apache Software Foundation is selected to act as the engine of JSP and Servlets. Database Server adopts 14 SQL Server 2021 Relational Database. Exchange Server is to be used to implement the mail service function. In order to prevent hacking system, two firewalls based on package filtration and proxy Server, namely, Cisico2511 router and Proxy Server , have been established. 外文資料翻譯 1 基于網(wǎng)絡(luò)的快速原型制造 摘要 ：這篇論文提出了新的基于快速原型快速產(chǎn)品開(kāi)發(fā)集成系統(tǒng) ,發(fā)展了通過(guò)充分利用迅速發(fā)展的計(jì)算機(jī)網(wǎng)絡(luò)和信息技術(shù)的網(wǎng)絡(luò)制造服務(wù)系統(tǒng) ,這個(gè)系統(tǒng)提供更好的在中小型企業(yè)中對(duì)于快速產(chǎn)品開(kāi)發(fā)的支持。提出了制造業(yè)的網(wǎng)絡(luò)化服務(wù)體系的架構(gòu)。此外 ,一些關(guān)鍵問(wèn)題 ,包括模型、規(guī)劃制造鏈 ,選擇可行的合作廠家 ,排列制造任務(wù) ,利用同步協(xié)作的工作環(huán)境 ,建立一個(gè)適合管理平臺(tái)等問(wèn)題得到了論述。可運(yùn)行 java 的解決辦法與網(wǎng)絡(luò)技術(shù) ,用于建立這樣一個(gè)網(wǎng)絡(luò)服務(wù)系統(tǒng)。最后提供了一
