Pbd is bbd ’ s matureness and extendability , it extends design reuse idea and emphasizes system reuse Pbd方法是bbd方法的成熟和擴展,它延伸了設(shè)計重用的理念,強調(diào)系統(tǒng)重用。
Then , the conception of smart sensor is introduced for multi - sensor system design to improve systemic characteristic including : flexibility , universality , extendability , extendability , data preprocessing , self - adjustability , data transmission by bus , and so on 然后本文提出了多傳感器系統(tǒng)的底層傳感器模塊應(yīng)具有通用性、可擴展性、對上層接口透明、開發(fā)傳承性、初級預(yù)處理和基于總線的數(shù)據(jù)傳輸?shù)仍O(shè)計要求。
A dynamic hierarchical description method for workflow is presented . the method provides a dynamic hierarchical way to define a workflow with non - determinate or dynamic factors . with this method , the main process defined at build - time can be reified and extended by the principle of the sub - organizations at either the build - time or the run - time . to ensure the consistency and integrity of the description , a series of constraint rules are also discussed to realize seamless integration between a decomposed process and its original one . this approach supports the description of unpredictable uncertainties , the dynamic hierarchy of business process , and the dynamic modification of enterprise organizations , and all of these improve the flexibility and extendability of workflow management systems dramatically 為支持流程中不確定性因素和動態(tài)因素的描述,提出了柔性工作流的動態(tài)層次描述方法,使得流程設(shè)計人員在流程定義階段定義的主流程可以在任意時刻由子組織的負責人進行細化和擴充.為保證動態(tài)層次描述的正確性和完整性,討論了動態(tài)層次描述的一系列約束規(guī)則,確保分解后的流程與原有流程實現(xiàn)無縫銜接.該描述方法支持對不可預(yù)知的非確定性因素的描述,支持業(yè)務(wù)流程的動態(tài)層次描述以及組織機構(gòu)的變化,極大地增加了工作流管理系統(tǒng)的柔性和可擴展性
The business system ' s subsystems are interrelated each other via the data interface , thus reduces mutual coupling and enables the system with strong extendability : a proper subsystem can be easily adjusted on business demand , and a new subsystem can be easily built to fulfill new business requirement 各個子系統(tǒng)之間通過數(shù)據(jù)接口進行關(guān)聯(lián),從而降低了子系統(tǒng)之間的耦合程度,使系統(tǒng)具有較強的可擴展性,既可以根據(jù)業(yè)務(wù)需求的變換改動相應(yīng)的子系統(tǒng),又可通過建立新的子系統(tǒng)來完成新的業(yè)務(wù)功能。
In order to reduce repeat work during developing nc system software and arising efficiency , program design method of extensible command set is applied based on software - overlap thoughts , which enhances program transportability and extendability . then nc program interpreter is realized 為了降低數(shù)控系統(tǒng)開發(fā)過程中程序員大量的重復(fù)性勞動,提高工作效率,應(yīng)用了基于軟件重用思想的程序開發(fā)方法? ?增量式程序開發(fā)方法,來實現(xiàn)代碼集的擴展,提高程序的可移植性,并依此開發(fā)了支持語言擴展的數(shù)控程序解釋器。
