題名: X Window Implementation of an Algorithm to Synthesize Ordinary Petri Nets
摘要: 平行系統之證明極為複雜,合成法用不著驗證,因此可減輕此複雜度之問題,現今大部分合成技術,並不討論電腦輔助設計,很少的電腦輔助工具具有整合分析、減少、模擬、查詢及合成的能力,派翠圖可模擬及分析平行系統。本人前曾發展-組合成律,可逐漸加大派翠圖,同時確保其邏輯正確無誤。本文指出所合成的派翠圖形成一新的種類,並提出時間矩陣的概念,其可記錄程序間之關係如平行、互斥、及序列。基於這一觀念,吾人發展出演算法,去決定何時可用此合成法,查覺違反此合成法的情況,及重新計算此一矩陣,此演算法之複雜度是O(K3),K是程序的總數。吾人前所發展之X視窗工具,以將此演算法具體實踐,此工具可設計、分析,模擬測試及合成通訊協定。; Vertification of concurrent systems faces complexity problem. Synthesis relieves this by avoiding verification. Most existing synthesis techniques do not deal with CAD tool. Few tools are able to integrate analysis, reduction, simulation, query, and synthesis in one software package as ours. Petri nets are used for modelling and analyzing concurrent systems. A set of synthesis rules were developed earlier1-3 for incrementally generating new processes without incurring logical incorrectness. This paper shows that the synthesized nets form a new class of nets and presents the concept of temporal matrix which records relationship (concurrent, exclusive, sequential, ... etc.) among processes. Based on this concept, we develop an algorithm to determinie the applicable rules, detect rule violations, and update the matrix. The complexity for the algorithm is O(K3) where K is the total number of processes. This algorithm has been incorporated int our X-Window based tool for the design, analysis, simulation, testing, and synthesis for communication protocols and others.2016-10-12T07:48:23ZIncentive of Loss Reserves Manipulation and Rate Regulation in Property- \n Liability Insurance Industry

題名: Incentive of Loss Reserves Manipulation and Rate Regulation in Property- \n Liability Insurance Industry
摘要: 損失準備金估計之正確與否,對於保險費率之公平性具有重要影響力。根據以往之研究發現,損失準備金可能受到保險人之人為操縱,以配合公司之財務目標。為防止造假與不適 \n當費率,監理機關通常要求費率必須事先核准,然而冗長之審查程序往往影響費率反映損失經驗之時效性,進而部份抵銷事先核准規範之效果。本文之主要目的在於提出一理論模型,以說產險費率決策過程中,由於保險人與監理機關雙方之資訊不對稱,保險人操縱準備金之道德危險與事先核准規範二者間之關係。本文之研究方法主要是以最佳控制理論(optimal control theory)為基礎,分析監督稽核策略對於保險人操縱造假程度之影響。本文之研究結論主要包括下列二點:(1)保險人造假程度程度愈嚴重,則愈容易受到監理單位之稽核;(2)監理審查時間長短將影響保險人之造假行為,審查拖延愈久,則造假程度愈高。因此根據研究結果,本文建議監理機關可藉由改善審查效率而抑制保險人之操縱造假行為。 \n\n ; The accuracy of loss reserve estimation is important for determining the fair price of an insurance policy. According to the previous studies, the loss \nreserves are vulnerable to manipulation by the insurer in order to pursue certain financial purposes. To prevent the manipulation and inadequate rates, \nthe insurer is required to obtain the approval of rates from the regulator. However, the regulatory review process may cause time lag between price and claim losses information and thus offset the effect of prior-approval.The purpose of this paper is to provide a theoretical model to explain the relationship between the moral hazard of loss reserves manipulation and prior-approval rate regulation for property-liability insurance rating decision,with consideration of asymmetric information between the insurer and the regulator. Based on the optimal control theory, this paper develops a dynamic optimization model to analyze the manipulation behavior of the insurer. The findings of this paper imply the following two points. First, the higher level of manipulation, the higher probability for the insurer being audited. Second, the regulatory reviewing lag will induce the level of manipulation, i.e., the longer the lag, the higher the level of manipulation. The results of this study suggest that the regulator can reduce the level of loss reserves manipulation through the improvement of efficiency in the regulatory review process.2016-10-12T07:44:11ZInternational Regime and Counterfactual Analysis: Regulating Transnational \n Corporations

題名: International Regime and Counterfactual Analysis: Regulating Transnational \n Corporations
摘要: 由於國際建制的個別特性,使得建制理論有過多解釋項的潛在缺失。反事實分析法能夠剔除建制理論中假的或多餘的解釋。本文以改良後的反事實分析法,研究「跨國公司行為規 \n範」的談判過程。雖然馬克斯主義、建制\\制度理論、以及霸權理論都提供有力的理論和証據,來解釋該談判的失敗。但是經過反事實分析法的檢驗後,只有霸權理論所提出美國政 \n府的決策,才是最重要的因素。其餘兩極解釋皆不成立。; Because of the idiosyncracies of international regimes, the overloading of explanatory variables becomes a potential threat to regime analyses.Counterfactual analysis (CFA) can reject redundant or false theoretical explanations in each regime analysis. After refinement, CFA is then applied to a study of the negotiation of the Code of Conduct for Transnational Corporations. Although Marxist, regime/institutionalism, and hegemony theories all provide convincing arguments and evidence to explain the failure of the Code negotiation, CFA points out the paramount importance of the American government`s decision on the issue and rejects the Marxist and regime/ institutionalist explanations.2016-10-12T07:43:52Z中國大陸工會組織之研究

題名: 中國大陸工會組織之研究
摘要: 本文從相關法令的變遷和工會會員密度的特色,剖析中國大陸工會的發展。結果發現:大陸工會的發展雖受政治面的影響很深,但改革開放以後,經濟面的影響力亦大。前者展現 \n於國有企業或國有企業為主的行業之工會會員密度較高,後者反映於非公有制企業的工會會員密度較低。目前台商雖以阻止工會組建來獲取經營上的便利,但大陸的工會主管機關 \n可能會強化其推動工會組建的政策。2016-10-12T07:43:37Z
