By the browser / web server / database structure and the technology of asp. net and xml, we achieve the expert system running on the network, extend the application and ensure its backward compatibility ; we have the deep research to the representation of knowledge and apply it to the system, extend the traditional method of rule based knowledge representation ; introduce the fuzzy sets, analyze the generalized possibility interval sets, and combine the linguistic variables and fuzzy sets ; the system adopts the forward and backward chaining, researches the reasoning under uncertainty and inexact reasoning ; and we depart knowledge base and inference engine, make the upgrade simple and maintenance convenient. in the last, we construct the potato produce manage system according to the phases of potato ' s growth to give a detailed instruct to its produc e
Net和xml技術，實現了網路化的專家系統，同時擴大了專家系統的應用范圍，提高了系統的後向兼容性；對專家系統中的知識表示技術作了深入探討，在傳統的基於規則的知識表示方法的基礎上，提出了基於規則擴展的知識表示方法，並較好地將其應用到本系統中；引入了模糊集合，分析並推導了廣義可能區間集，將其應用於模糊知識的表示，將語言變量和模糊集合結合起來；提出對系統採用互動式知識獲取途徑、雙向推理控制策略，對不精確推理和不確定性推理的傳播演算法作了一定的研究，成功地將其應用到馬鈴薯專家系統的構建之中；採用知識庫和推理機相分離的方法，使得系統升級簡單易行。 -
According to initial data user puts into database and knowledge in the knowledge base, inference engine makes proper rolling rules and achieve the important parameters of rolling mill through its forward chaining
推理機採用正向推理機制，根據用戶輸入的初始信息，利用知識庫中的知識，推理出合理的軋制規程，計算出軋機的主要結構參數。 -
In this paper, i analyze the practical condition of the cad applied to the transformer, make some researches on the primary technology of the expert system based on the forward chaining, on the modeling technology based on the assemble feature, on the design ideal based on the parametric drawing, on the principal of the database. i develop the practical cad software system about the transformer structural project based on the previous principal and ideal, applying to the vc + + system and the regeneration development tool of the autocad system. the system establishes the foundation for the integration of the transformer design information, reduce the time of the transformer design, increase the design efficiency and the economic effectivity of the enterprise, and have a great applicational value
本論文分析了cad在變電設備行業中運用的實際情況，先後研究了基於正向推理的專家系統的基本技術，研究了裝配特徵的造型技術，研究了參數化繪圖的設計思想，研究了數據庫管理的基本思想；在vc + +環境下和autocad二次開發工具objectarx的基礎上，開發了基於上述技術和思想的變壓器結構方案cad應用軟體系統，為變壓器製造業的信息化和系統設計的集成奠定了基礎，在一定程度上能減少變壓器總體設計時間，提高企業的設計效率，能為企業帶來較大的經濟效益，具有較大的應用價值。
