A case study on the object-oriented framework for modeling product families with the dominant variation of the topology in the one-of-a-kind production

Traditional configuration-based product family modeling techniques do not yield favorable solutions for modeling the product families with the dominant product topology variations. This paper presents the case study for the modeling of variations of the product configuration, parameters, and topologies in mass production of custom windows and doors in a one-of-a-kind production (OKP) company. The case study is based on the object-oriented product family modeling framework we developed for OKP which is characterized by the dominant product variation by topology. The problem of variation in topology in our framework is solved by the manual model transformation in the computer-aided design module which creates a new metamodel of products with the desired topology and which is the basis for a further, automatic model transformation. Usage of our framework has a positive effect on the level of the product customizations and shortening of the leading time which helps OKP companies in obtaining a better position at the market. Our software solution for the designing and manufacturing of custom windows and doors based on our framework is implemented in more than 300 mostly small- and medium-sized enterprises. It proves our concept which can be used for the realization of the information systems for computer-aided one-of-a-kind production in the companies with a different production plan.

Web-service-based parametric design reuse for parts

Design reuse of parts plays an important role in product design. In this study, we present a parametric design reuse framework for parts design based on web service. The proposed framework borrowed the ideas from component model of software reuse, such as reuse service, separation of interface, and realizing procedure. The reuse framework for parts can be divided into three layers: the design interface layer, the design service layer, and the design result layer. Firstly, we built parametric templates for parts design using software integrated technology (e.g., iSIGHT). The parametric, automatic, and integrated design for parts can be accomplished through the templates. Then, we deployed parametric templates for parts design using web encapsulation technology (e.g., EASA). Finally, we developed a design reuse prototype system using heat pipe exchanger design reuse for demonstration based on the proposed framework.

A process-centric engineering Web services framework

Collaborative and distributed engineering Web services are emerging as a viable alternative to the traditional design and engineering process automation. Existing approaches have limitations in supporting long-running engineering transactions, automatic engineering process orchestration and choreography, synchronous and asynchronous conversation, and geometric abstraction for transmission and sharing. In this paper, we present a process-centric engineering Web services framework to overcome these limitations by utilizing BPEL-based (business process execution language) process templates and coordination broker-based conversation support. This paper also discusses the synchronization of engineering Web services, which can be either peer-centric or process-centric to support long-running engineering transactions and conversation. The process orchestration and choreography broker works as a service dispatching and aggregation agent for executing process templates, which enables the individual activity of the engineering process to dynamically invoke one of the alternative Web services through the run-time process brokering. Further, the paper presents how to support collaboration over the running process using conversation policy .

An RFID-based enterprise application integration framework for real-time management of dynamic manufacturing processes

Enterprise application integration (EAI) is an important issue for a company trying to transform itself into a ubiquitous real-time organization. However, traditional techniques for EAI are only suitable for integrating the virtual information among different applications. The challenge of integrating physical objects with corresponding business processes and applications at the right time and location is a critical concern for companies building a real-time enterprise (RTE) information system. In this research, we proposed an EAI framework based on radio frequency identification (RFID) technology. On the basis of this framework, a prototype system is developed to demonstrate the applicability of the framework in a shop floor environment. This paper also presents a RFID-based standard operation procedure to configure a prototype system for a particular shop floor operation and an operator orientation for performing the corresponding tasks. The findings of this paper demonstrate that the proposed framework is more capable than most current industrial practices in both managing dynamic manufacturing processes and in providing real-time visibility of work-in-process information. Using this framework, an enterprise can easily integrate an RFID-based solution into its IT infrastructure and manufacturing environment to facilitate real-time management of dynamic production operations.

Framework for morphometric classification of cells in imaging flow cytometry

Imaging flow cytometry is an emerging technology that combines the statistical power of flow cytometry with spatial and quantitative morphology of digital microscopy. It allows high‐throughput imaging of cells with good spatial resolution, while they are in flow. This paper proposes a general framework for the processing/classification of cells imaged using imaging flow cytometer. Each cell is localized by finding an accurate cell contour. Then, features reflecting cell size, circularity and complexity are extracted for the classification using SVM. Unlike the conventional iterative, semi‐automatic segmentation algorithms such as active contour, we propose a noniterative, fully automatic graph‐based cell localization. In order to evaluate the performance of the proposed framework, we have successfully classified unstained label‐free leukaemia cell‐lines MOLT, K562 and HL60 from video streams captured using custom fabricated cost‐effective microfluidics‐based imaging flow cytometer. The proposed system is a significant development in the direction of building a cost‐effective cell analysis platform that would facilitate affordable mass screening camps looking cellular morphology for disease diagnosis.     

Creating a Fit Between BPR and IT Infrastructure: A Proposed Framework for Effective Implementation

As business imperatives change and new high-capability information technologies (IT) appear, organizations recognize the need to remain at the forefront of change by reengineering their business processes and implementing enabling responsive IT infrastructures. However, experience in this context indicates a lack of comprehension of essential elements and their mutual relationships that can contribute to the success of business-process change-implementation efforts. This article proposes a framework for managing IT for effective business-process redesign (BPR) implementation. After establishing BPR principles, components, and the relationship of BPR to some organizational and technological approaches, it presents the role and benefits of IT in BPR. The article then discusses in detail the core elements of the framework. Its theme is that an IT infrastructure that covers issues of BPR strategy development, IT strategic alignment, IT infrastructure development, IT sourcing, legacy systems reengineering, IS integration, and IS function competence is essential and critical for effective implementation.     

A solution procedure for integrated supply chain planning problem in open business environment using genetic algorithm

Enterprise applications are increasingly becoming capable of sharing information and coordinating decisions autonomously without any human intervention. This open business environment gives rise to several new supply chain planning problems that have to be solved by individual entities of a supply chain. This paper first mathematically formulates the supply chain planning problems emerging in the open business environment and second proposes a heuristic solution procedure based on the framework of genetic algorithm applicable to large-scale problems. The procedure has two stages as the original problem is decomposed into two sub-problems in an effort to reduce the overall problem complexity. The performance of the proposed algorithm is empirically proven to be effective in both solution quality and search time in various problem sizes.
