Business process modeling plays an important role for the documentation and analysis of organizational processes and for the specification of requirements for information systems. Currently, there are many standards for process modeling, and each represents a different approach to modeling and provides different opportunities for creating models. Thus, same models created in different modeling languages differ in terms of their expressiveness, according to each standard. The goal of this thesis is to evaluate the effectiveness of selected business process modeling standards. The effectiveness of standards will be evaluated on two levels. First, in terms of their semantics and second, in terms of their syntax. Evaluation of standards in terms of their semantics will be based on the comparison of standards with a business process metamodel created within the project Opensoul. This model defines a set of basic elements and their associations at a basic level of process modeling. Evaluation of standards in terms of their syntax will be based on the comparison of standards with a framework proposed by Moody and Hillegersberg. The results of this comparison should show which standard best supports defined criteria. The evaluation framework will be applied on the following process modeling standards: BPMN, EPC and IDEF3. Based on the results obtained their strength and weaknesses will be discussed. The main contribution of this thesis can be seen both in the analysis of the element set of selected process modeling standards and further in the comparison of standards according to the evaluation framework.

全球消費者需求快速改變，產品生命週期明顯縮短，不允許過多的存貨屯積，故產品的配送傾向於「少量、多樣、快速」的配送服務，企業希望擁有一個高效率的國際物流服務網路來提供企業在供應鏈管理上更有效率的監督與管控。 　　就國際物流（Global Logistics）來說，海運業者是否能共享正確即時（real time）的資訊，正是其關鍵成功因素。而海運產業中各角色資訊與資源的整合，有賴於企業建構其電子化企業的應用系統架構藍圖；因此，海運產業除了建構企業電子化之應用資訊系統外，更應著重於各系統間的整合與資料交換，發展或利用適當的資料整合與交換技術；對海運而言，系統整合不僅僅是應用系統間資料的交換，更應達到與流程緊密的搭配，才能真正完成進出口流程電子化、資訊與資源共享等目標。然而，各應用系統間資料模式的不一致性、資料交換的不即時性，也為資料交換帶入雪上加霜的困境。 　　有鑑於此，本研究以「個案研究」方式提出一個利用流程分析，建構海運跨組織企業流程模型。主要作法為從海運企業個案營運流程的分析，利用IDEF0與IDEF3方法定義海運產業企業流程模型，並且整合各不同企業流程。透過個案資訊架構分析，提出適合海運業跨組織資料交換之資訊架構，並以此資訊架構改善各企業流程，最後整合改善後流程模型，建置海運跨組織進出口流程模型。

The scope of this thesis is the field of business process modeling and additionally the usability of business process models in areas like conceptual analysis of IS/ICT, business process reengineering and business process management. For the purpose of evaluation of the usability of current standards for business process modeling, an framework for comparison of various characteristics of these standards is proposed. This thesis has two aims. Primarily, to develop an approach for evaluation of business process modeling standards, and as a secondary aim, to apply this evaluation model onto a set of selected standards for business process modeling and thus perform a comparison of these standards. The evaluation model has two main components. The first part is to create a set of characteristics which represent two existing points of view onto the exploitability business process modeling (e.g. during the development of IS/ICT and during BPR/BPM1). During the identification of particular characteristics, a research into the related literature and other sources has been performed to provide a sufficient basis for this activity. The second part of the developed approach is to the application of PEMM (Process & Enterprise Maturity Model), which was developed by Dr. M. Hammer for the purpose os auditing the maturity of business processes. Both of these parts are then put together into one evaluation framework. Based on information gathered from the respective specifications of particular standards, related literature and articles, we've performed an application of this evaluation framework on three standards for business process modeling: EPC, BPMN and IDEF3. The benefits of this thesis could be seen as a creation of a very own approach for evaluation of business process modeling standards. Additionally by performing the comparison of these three standards for business process modeling we've created a guideline which could be there fore applied by the potential reader during the decision making of what standard to use for business process modeling (in the context of expected purpose of this modeling).
