應用文字探勘與XBRL技術於企業策略分析決策支援系統之研究

連子杰, Lien,Tzu-Chieh Unknown Date (has links)
投資人在投資決策之過程中,所分析之資料可分為財務性與非財務性資訊兩大類,然而受限於傳統財務資料格式之不一致,可能需花費額外之財力與物力來處理,甚至浪費精力於資料的重新輸入。另一方面,非財務資訊在投資決策過程中日益重要,但其龐大的資訊揭露量卻往往徒增投資人閱讀與搜尋上之不便,甚至降低了可閱讀性。 有鑑於上述兩大投資分析不便之處,本研究運用文字探勘(Text mining)技術,嘗試處理股東會年報中與企業策略相關之非財務性資訊,以協助閱讀者有效率地分析、整理這些半結構化,甚至是非結構化文字資訊。另一方面,本研究利用可延伸企業報導語言(eXtensible Business Reporting Language, XBRL)不受軟體平台限制,可於網路上自由下載流通等特性,作為財務資訊之資料來源,同時建立一種新的分析模式,透過連結機制之設計以連接非財務性與財務性資訊,並運用ROMC系統分析法與雛型系統設計法完成本企業策略分析決策支援系統,希冀能協助投資人能於短時間內瞭解並印證標的公司之產業發展與競爭策略,提升決策品質。 / There are two main data types in investment decision process: financial and non-financial. Because the inconsistent of data type in traditional financial data, investors may have more additional costs to solve this problem. In addition, non-financial data become more and more important in investment decision process, but huge amount of non-financial disclosure may reduce the readability and increase the difficulty of searching. To solve the above problems, we try to use text mining technology to handle the semi-structured or unstructured non-financial data related to business strategies in the annual reports of public companies effectively and efficiently. In addition, we use XBRL (eXtensible Business Reporting Language) to be our financial data resources because of its interoperability and re-usability. We also develop a new analytic method to link financial and non-financial data together. Finally, we use two system methodologies: R.O.M.C. and prototyping to design and build our business strategy analysis decision support system in order to help investors understand and prove strategies in companies, and improve the decision quality which they make.

資產負債管理中模式整合問題之探討 / Model integration for asset liability management

陳政裕, Chen, Cheng Yuh Unknown Date (has links)
傳統的資產負債管理(Asset-Liability Management,ALM)研究大多強調數量分析方法,並未考慮資料來源的問題。然而在銀行實務上,資產負債管理人員卻必須根據現有內外部資料來釐定資產負債組合的整体政策。在決策支援系統中,模式整合的功能包含模式之組合及連結等,可用以整合數量分析模式與相關資料。本研究運用人工智慧技術來探討資產負債管理中模式整合之問題。藉此可以明瞭ALM的分析流程,以作為銀行人員訓練之參考。另一方面由於應用黑板架構發展系統,也可以提供一個有彈性的整合環境,以反應使用者需求及資料異動狀況,亦可彈性新增、刪除及修改模式整合過程中的資料結構與知識內涵,以為未來連接理論技巧與實務環境之參考。 / The computer support for Asset Liability Management (ALM) in the literature emphasizes on the mathematical analysis and does not address the data source problems. In the practical banking environment, however, ALM decisions are made based on the dynamic internal and external data changes. Therefore, an ideal ALM decision support system has to consider the integration of data sources and mathematical analysis. Traditional Decision Support Systems (DSS) rely on the expert's assistance to understand the problem and formulate or integrate appropriate models. There is a growing recognition that incorporates Artificial Intelligence techniques (Al) into the DSS can enhance the acceptance of these decision aids by management.   This paper intends to develop an Intelligent Decision Support System (TDSS) and addresses the model integration concept for the ALM. In the paper, model integration is defined as a series of processes from which important decision making information is inferred through automatic data model mapping and mathematical model conversion. The investigation of model integration concept helps the ALM analysis process understanding which can be useful for baaldng personnel training. On the other hand, the IDSS provides a flexible integration environment in which the system can flexibly response to the user's analysis request with the updated data situations. Since the blackboard architecture used for the system development supports the modularization structure, its inherent maintainability aLows a flexible update of the domain knowledge and data structure, and can therefore serve as a testbed to evaluate the potential integration approaches of various ALM data and mathematical models.

運用黑板架構發展智慧型決策支援系統之解釋功能-以授信審查為例 / Developing an explantaion facility for intelligent decision support systems using blackboard architecture - A loan evaluation example

連柏偉, Lein, Boe Wei Unknown Date (has links)
智慧型決策支援系統(Intellignet Decision Support Systems)的特點是可以同時處理定性和定量資料於同一個系統中,以同時執行各種知識推論及數量模式之運算。黑板架構(Blackboard Architecture)的做法是將決策支援求解過程的資料、模式和知識運用情形記錄於一共同工作區─稱之為黑板(Blackboard),將模式及知識記錄在所謂的知識源(Knowledge Sources)中,並提供較有彈性之控制機制,應可提供較佳的解釋功能。以黑板架構為基礎的智慧型系統多應用在科學及工程方面,在管理方面卻寥寥無幾;管理問題多半屬於半結構性或非結構性,良好的解釋應為智慧型決策系統之重要功能。本研究擬就銀行業之授信審查做為本系統之專業領域知識(Domain Knowledge),運用黑板架構中的階層化問題表現方式及模組化知識源分類之特性,建立提供完善解釋功能之智慧型授信決策支援系統。 / Incorporating artificial intelligence (AI) technique is critical to improve the functionality of decision support systems. Explanation function for consultation-based systems has been emphasized in the literature and should be considered important in developing intelligent decision support systems. Blackboard architecture can support a well-organized explanation facility due to its structurization of problem solving space, modularization of domain knowledge, and flexibility of reasoning control. Applying blackboard systems to managerial domain gets attention recently. Since most managerial consultation problems are unstructured or semi-structured, good explanation facility should be able to enhance the consultation effectiveness. The thesis investigates the potential of developing an explanation facility on the blackboard architecture using the loan evaluation as an example. During the interactive consultation process, the system can answer questions such as "What?", "Why?", "How?", and "Where?" with a friendly user interface. In terms of contribution, the inclusion of explanation facility can potentially increase the willingness and confidence of decision makers in using intelligent decision support systems. On the other hand, applying the graphic user interface to the development of explanation facility based on the blackboard architecture can make the reasoning process transparent and enhance the acceptance of this AI technique to managerial problem solving.

影響國際快遞物流服務客戶喜好因素之研究-暨客戶服務決策支援系統概念設計 / Research into customer preferences factors in the field of global express logistics and conceptual design of customer service decision support system

鄭銀華, Cheng, Yin Hua Unknown Date (has links)
產業的成熟與市場的飽和,使得產業的競爭變得愈來愈以成本和服務為導向,而激烈的市場競爭促使服務價格降低求存,以致物流業的服務素質及水準只能「將貨就價」,然而消費者意識的抬頭與服務科學的興起,使得服務品質的管理日益重要。因此,國際快遞物流企業要在提升服務及降低成本的驅動下,透過結合物流產業相關科技優勢與運用服務科學思維,找出顧客對產品及服務的喜好以增進服務效益,進而創新服務。 本研究以層級分析法(AHP)之操作步驟,找出對映客戶需求的四個服務品質構面及衡量構面的十二個準則,在建立一顧客喜好因素架構後,訪談某國際快遞物流前四十大客戶,以Expert Choice的整體階層不一致性判斷值(Overall Inconsistency Index, O.I.I)進行效度檢驗,通過一致性之問卷為32份。研究分析結果發現影響國際快遞物流顧客的喜好之準則,其權重依序是「誠實值得信賴」、「容易使用」及「遞送速度」,構面則以反應性及關懷性最為客戶所重視,並且從驚喜性構面發現,客戶在意的是持續性的改進與穩定的提供服務,而不喜歡沒有系統的改變與創新。在統計分析中,客戶重視程度離散度較大的有「遞送速度」及「誠實值得信賴」兩準則,顯示有特別重視此兩項因素之樣本群,而某些喜好因素間具有中度相關之關聯。 接著本研究為落實服務科學之思維與方法,將影響客戶喜好因素之架構結合決策支援系統,以決策支援系統的三個主要元件,資料庫、模式庫、對話管理提出概念設計,以重要性-績效矩陣(IPA)作為改善服務之排序參考,以及使用品質機能展開(QFD)作為在設計與創新服務的過程中納入客戶需求之方法;此外,也使用權重及客戶滿意度作為瞭解客戶對國際快遞物流服務之偏好程度及對方案之態度參考,使國際快遞物流企業能更有效率的提供滿足客戶個人偏好的服務。 / The maturity of industries and the saturation of markets make industrial competition more and more cost-oriented and service-oriented. To survive the keen market competition, the logistic industry has no choice but to reduce price, which leads to a lower level of service quality. With the uprising consumer awareness and service science, the management of service quality becomes more and more important. Driven by the need of higher service quality and lower cost, international logistic enterprises should combine relevant technical advantage and service science intellect to meet consumer demand, increase service efficiency, and innovate service. This research utilizes AHP method to create 4 service quality dimensions corresponding to customer demand and 12 criteria to measure these dimensions. After the establishment of customer preference framework, interview with 40 largest customer of a certain international logistic company and then examine the validity by the O.I.I. of Expert Choice. There are 32 questionnaires pass the consistency check. Analysis found that the weight of criteria which effect customer preference in sequence is “Integrity / trust worthiness”, “Easy to use”, and “speed of delivery”. As to dimensions, customers value “Respond” and “ Understand me” most. From the “Surprise” dimension we found customer need continuous improvement and steady service. Unsystematic changes and innovates are not preferred. In statistic analysis, “Speed of delivery” and “Integrity / trust worthiness” two dimensions have greater level of scatter on customer emphasis, which indicates there are some samples have special emphasis on these two factors and some factors have mid-level correlation. To practice the intellect and method of service science, this research combines the framework of factors that affect customer preference and decision support system. Concept designed by the 3 main part of a DSS : Database, Model base, and Dialog management, use IPA as the reference of service sequence improvement, and utilize QFD to bring in customer demand in the design and innovation of service. In addition, use weight and customer satisfaction as refer to understand international logistic service preference level and attitude toward programs. To bring more efficient and customer preference satisfied services.
