Item A framework for propagating measures of performance throughout organizations using object-oriented technology(Texas Tech University, 1997-05) Marquis, Gerald P.The merging of Business Process Reengineering (BPR) with Object-Oriented Technology (OOT) has been substantively advanced by many authors [Carr and Johansson, 1995; Jacobson et al., 1995; Taylor, 1990, 1995; Yourdon, 1994]. BPR is defined as "The fundamental rethinking and radical redesign of business processes to bring about dramatic improvements in performance" [Hammer and Stanton, 1995, p. 3]. These business processes will most often span across multiple business functions. A business process is "a set of linked activities that take an input, transform it, and create an output" [Carr and Johansson, 1995, p. 9] while a business function refers to the fragmented simple, repetitive steps that are carried out by single departments within the organization [Hammer and Champy, 1993]. This makes it very difficult for the traditional information systems (IS), that were developed to support business functions, to also support a newly developed business process. Object-oriented technology (OOT) is becoming the paradigm of choice to support business process reengineering due to its flexibility and reusability.Item An extended object-oriented modeling method for business process reengineering(Texas Tech University, 1999-05) Nakatani, KazuoExisting Business Process Reengineering (BPR)methodologies rely on modeling approaches. Due to high risks involved in BPR, an organization needs a modeling method that efficiently supports a BPR project. The dissertation has identified a problem in BPR as the lack of an efficient modeling method to support a BPR project under the concept of business process change management. The dissertation proposes a modeling method that utilizes the object-oriented (00) concepts to resolve this problem. A unified research methodology has been used to develop the modeling method. The dissertation first presents a conceptual model as a theoretical basis on which the proposed modeling method has been developed. While developing the conceptual model, the desired behavior of a BPR modeling method has been determined. Then, three types of knowledge required to produce the behavior have been specified. The first type of knowledge contains kinds of information about a business process that should be captured in a model. The second type of knowledge specifies BPR project activities that should be carried out during a BPR project. The last type of knowledge contains which information about a business process is relevant to each BPR project activity. The dissertation then presents an extended 00 modeling method that has been developed based on the above conceptual model. The method consists of three main parts: (a) a modeling framework, (b) steps of the modeling method, and (c) information collection templates and information presentation formats. The proposed method has been compared whh three existing methods to evaluate its comprehensiveness. Three expert committee members have evaluated the four methods for the comparative analysis. The comparative analysis has showed that the proposed method is more comprehensive than the three benchmark methods in four areas: (a) ability to capture more information about a business process, (b) abilhy to support more BPR activhies, (c) ability to support particular BPR activhies in more detail, and (d) ability to provide more information about a business process for a specific analytical action.Item An object-oriented system design for a web-based electronic product evaluation and recovery management system(Texas Tech University, 2002-05) Gao, ZongThe original idea of this electronic product evaluation and recovery management system ("SYSTEM") comes from three previous done projects. The SYSTEM covers all the end-of-life stages in an electronic product's life cycle. The primary parts of this SYSTEM include a front-end user-interface, five functional modules, a core PMM module and back-end databases. The SYSTEM can be applied in various industrial environments as EOL processing guidelines or product design and evaluation reference. The system model design was implemented using an object-oriented (00) modeling approach. The 0 0 modeling of the SYSTEM is given out step by step in this thesis. All components and functions of important modules are presented in detail. A brief evaluation of the system model is included. The system implementation was completed using Java, XML, and web-based tools in 2001. It is now running on a Windows 2000 server in the Advanced Manufacturing Lab that can be accessed through Internet.Item Object-oriented modeling for the integrated process planning and production scheduling system(Texas Tech University, 1998-05) Zhang, DaguangThis research explores an object-oriented generic model for integrated process planning and production scheduling. The research employs the most advanced objectoriented modeling technique and tools to implement a hierarchical-interactive process planning approach which integrates the process planning and production scheduling functions through a stepwise integration advancement. The integration of process planning and production scheduling is a comprehensive, controversial, and complicated topic to both academia and industry. Both process planning and production scheduling play important roles in manufacturing systems. Traditionally, these two functions are separated and have their own planning goals, constraints, and methodologies. The integration of these two functions has been driven by the fact that many process plans cannot be executed on the shop floor because the production constraints are not considered during the process planning. However, the implementation of the integrated planning remains an enigmatic task because of its complexity. While many studies have been conducted, more efforts are yet to be invoked. In this research, the integration of process planning and production scheduling is approached by a Hierarchical-Interactive Process Planning (HIPP) architecture, which has been modeled in the object-oriented paradigm. The HIPP includes three levels interactions between process planning and production functions. The functional and data gaps in the existing separated planning are bridged through object-oriented systems models.
