【摘要】：汽車生產(chǎn)管控系統(tǒng),是為汽車零部件生產(chǎn)廠商量身定做,意在使這些企業(yè)的生產(chǎn)工作通過計算機技術實現(xiàn)自動化辦公。這些企業(yè)的生產(chǎn)工作主要由兩部分組成:日常的數(shù)據(jù)維護工作和工廠的生產(chǎn)流程工作。前者對諸如項目材料信息、財務信息、職工信息等企業(yè)生產(chǎn)中相關的數(shù)據(jù)進行維護和管理;后者則需要根據(jù)企業(yè)自身產(chǎn)品生產(chǎn)制造時的工藝特點,結(jié)合車間中可供調(diào)配的資源,合理調(diào)度生產(chǎn),保證產(chǎn)品能夠按時按量生產(chǎn)。而在企業(yè)生產(chǎn)工作當中,難免出現(xiàn)這樣那樣的原因?qū)е聠T工無法繼續(xù)行使當前職責或完成當前任務,如果對這個問題置之不理,可能對企業(yè)的日常工作和生產(chǎn)流程工作帶來阻礙,甚至造成經(jīng)濟損失,同時也給系統(tǒng)安全造成極大威脅。在這樣的情況下,為企業(yè)設計安全有效的授權委托功能,成為了開發(fā)當中確保系統(tǒng)正常運行的當務之急。對于一個企業(yè)生產(chǎn)管控系統(tǒng)而言,授權委托機制是保證系統(tǒng)正常運行不可或缺的一部分,它的核心功能是為在用戶暫時或永久不能承擔系統(tǒng)分配的職能時,提供一種安全有效地機制,將用戶的權限轉(zhuǎn)移給其他用戶,代替行使其職責。對于汽車生產(chǎn)管控軟件而言,在實施委托時,權限是否涉及工作流要區(qū)別考慮,窗體模塊中不同粒度權限的轉(zhuǎn)移也同樣需要由模型區(qū)別控制。本文所研究的核心和重點,就是提出一種能服務于此類系統(tǒng)的授權委托模型。就目前而言,比較主流的委托模型主要有RBDM模型、TBDM模型、PBDM模型以及它們的擴展體、結(jié)合體等等。這些模型在以往的應用中發(fā)揮了各自的優(yōu)點和長處,起到了很好的作用。但隨著信息科技的發(fā)展和時代的進步,各軟件系統(tǒng)的用戶量、數(shù)據(jù)量等都呈指數(shù)增長,客戶需求也呈多樣化趨勢,傳統(tǒng)的委托模型在這樣的情況下便顯得不夠靈活簡便,對于新系統(tǒng)的適用能力也有一定不足,模型設計上都存在或多或少的缺陷。綜上所述,本文立足于梯隊的課題項目,并與企業(yè)具體需求相結(jié)合,通過對上述傳統(tǒng)模型的研究與借鑒,提出了一種新的授權委托模型M-PBDM(Multi-Permission Based Delegation Model)。本模型首先對企業(yè)的組織架構進行抽象剝離,在系統(tǒng)中定義了角色、用戶、任務等概念,并對系統(tǒng)中的權限加以區(qū)分,分為工作流相關權限集WP與工作流無關權限集NWP�；谶@樣的分類,在工作流相關權限集下的權限轉(zhuǎn)移,是發(fā)生在用戶獲得的任務的基礎上,權限的轉(zhuǎn)移即用戶任務的轉(zhuǎn)移;而在工作流無關權限集下的權限轉(zhuǎn)移,是發(fā)生在用戶獲得的角色的基礎上,通過進一步區(qū)分可轉(zhuǎn)授權限集與不可轉(zhuǎn)授權限集,粗粒度權限集和細粒度權限集等,進行用戶權限的轉(zhuǎn)移委托。通過一段時間的實踐和改進,該模型在汽車生產(chǎn)管控軟件得到了很好的應用,降低了系統(tǒng)風險,提高了系統(tǒng)的可用性和安全性。
[Abstract]:The automobile production control system is tailor-made for the automobile parts manufacturers, which is intended to automate the production of these enterprises through computer technology. The production of these enterprises mainly consists of two parts: daily data maintenance and factory production process. The former carries on the maintenance and the management to the related data such as the project material information, the financial information, the staff information and so on in the enterprise production; In the latter case, according to the process characteristics of the production and manufacture of the enterprise's own products, combined with the resources available for deployment in the workshop, the production should be reasonably scheduled to ensure that the products can be produced on time and according to the quantity. In the production work of an enterprise, it is inevitable that one reason or another will result in employees being unable to continue to exercise their current duties or to complete their current tasks. If this problem is ignored, It may hinder the daily work and production process of enterprises, even cause economic losses, but also pose a great threat to the security of the system. In this case, the design of a secure and effective delegation of authority for enterprises has become an urgent task in the development process to ensure the normal operation of the system. For a production control system of an enterprise, delegation mechanism is an indispensable part of ensuring the normal operation of the system. Its core function is to enable the user to temporarily or permanently fail to undertake the functions assigned by the system. Provides a secure and effective mechanism to transfer user rights to other users instead of exercising their responsibilities. For the automobile production control software, whether the authority involves workflow should be considered differently, and the transfer of different granularity permissions in the form module also needs to be controlled by the model. The core and key point of this paper is to propose an authorization delegation model which can serve this kind of system. At present, the mainstream delegation models mainly include RBDM model, TBDM model, PBDM model and their extender, combination and so on. These models have played a good role in the past applications. However, with the development of information technology and the progress of the times, the number of users and the amount of data of each software system are increasing exponentially, and the customer demand is also diversified. Under such circumstances, the traditional entrustment model is not flexible and simple enough. The applicability of the new system is also inadequate, and the model design has more or less defects. To sum up, this paper bases itself on the project of echelon and combines with the specific needs of enterprises. Through the research and reference of the traditional model mentioned above, a new authorization delegation model M-PBDM (Multi-Permission Based Delegation Model).) is put forward. This model firstly abstracts the organizational structure of the enterprise, defines the concepts of role, user and task in the system, and distinguishes the permissions in the system, which is divided into workflow related privilege set WP and workflow independent permission set NWP.. Based on this classification, the transfer of authority under the relevant permission set of workflow occurs on the basis of the task acquired by the user, and the transfer of authority is the transfer of the user task. On the basis of the role acquired by the user, the privilege transfer under the workflow independent permission set is based on the distinction between the transferable permission set and the non-delegated permission set, the coarse-grained permission set and the fine-grained permission set, etc. Delegate user authority transfer. Through practice and improvement for a period of time, the model has been applied to the automobile production control software well, reducing the system risk and improving the usability and security of the system.
