Abstract

Purpose

The CIM framework pursues the integration of components in a manufacturing enterprise by means of computer systems. This, however, may be obstructed due to heterogeneity in the field: programmable controllers, robots, sensors and actuators, etc. in communications: different kinds of networks and/or field buses; and in the programming tools for all these devices. Thus a solution is needed to integrate heterogeneous software/hardware components in a well‐defined and flexible fashion. This paper seeks to address these issues.

Design/methodology/approach

This paper proposes a metalanguage, called H, and a set of tools that serve for designing, implementing, deploying, and debugging distributed heterogeneous software on the shopfloor. The metalanguange includes fault‐tolerance and real‐time mechanisms, among other features.

Findings

The use of a framework that can integrate different software and hardware components enables the engineer to take advantage of the best features of each existing technology. The use of object‐oriented techniques, concurrent and distributed programming, and the isolation of heterogeneous parts, have also important benefits in the reusability and optimality of the solutions.

Practical implications

The use of a metalanguage like H, that separates the parts of the application that depend on particular (heterogeneous) components from the parts that are portable, has, as a main implication, important improvements in the development time, effort, and cost of CIM projects.

Originality/value

H is the first metalanguage coping with heterogeneity through the complete development cycle of software for manufacturing applications. It also provides a formal and well‐defined framework for future extensions.

Abstract

Purpose

The purpose of this paper is to demonstrate a multipurpose inspection robot that can both walk on the ground and climb on poles. The structure design, size optimization, kinematics analysis, experiment and arithmetic of the robot are discussed in the paper.

Design/methodology/approach

The robot consists of three adjustable modules and a two-degree-of-freedom parallel mechanism in tandem, and the wheel-finger mechanism of each module can realize wheel-finger opening and closing for fast movement and obstacle crossing. This paper uses geometric analysis and simulation analysis to derive size optimization, and vector coordinate method to derive kinematics. Finally, the experiment is carried out by simulating the working environment of the robot.

Findings

The robot can realize ground walking and ground turning through the robot entity prototype experiment on the built working environment and efficiently realize 0°–90° pole climbing by the assemble design, optimization and machining. In addition, the robot can also smoothly complete the state transition process from 0° ground to 90° pole climbing. Furthermore, the robot shows good environmental self-adaptation and can complete daily inspection work.

Originality/value

The robot can pitch and yaw at a large angle and has six-legged characteristics. It is a multipurpose inspection robot that can walk on the ground and climb on poles. And through structure design, size optimization, kinematics analysis and simulation, the existing robots’ common shortcomings such as poor barrier-crossing ability and poor environmental adaptability are solved.

Abstract

Purpose

The purpose of this paper is to propose a real‐time food receiving operations management system (RFRS), focusing on demonstrating the use of a case‐based reasoning (CBR) and radio frequency identification (RFID) technology in managing the complex food receiving activities in distribution centers, to deal with the global concerns in food safety management.

Design/methodology/approach

The proposed system includes a CBR engine for generating customized operating procedures by retrieving and analyzing relevant knowledge stored in the database and case library. In addition, RFID technology is adopted to gather real‐time inventory information for visualizing inventories, work stations, and equipment status.

Findings

The significance and contribution of RFRS in the context of managing unstructured operations in distribution centers for the food receiving process are demonstrated by adopting the system in one of the Hong Kong‐based logistics companies. The achieved improvement of order fulfillment helps achieve a systematic management in operations process flow. Moreover, the time saving in resource assignment helps improve the operations efficiency of the receiving zone. Hence, the decrease in the faults of quality checking helps improve the service and quality level. All of the above demonstrate the feasibility of the RFID‐based decision support system.

Originality/value

A superior method for the management of quality control and service of the receiving process is essential for the success of food distribution centers. However, the complexity of these management processes increases with the rise of customization of service in the supply chain. Hence, such increase in the operation complexity leads to the increase in operation time and, consequently, a decrease in the service quality. The real‐time food receiving operations management system proposed in this paper integrated RFID and case‐based reasoning technology in dealing with food warehouse receiving operation assignment. This is a brand new application combining the two technologies in the field of food reception in warehouses. With the support of the system, the efficiency and the customer satisfaction are improved.

Abstract

Purpose

The purpose of this study is to survey knowledge management (KM) practices and to examine the applications and technologies adopted when developing the knowledge management system (KMS) in build‐to‐order supply chains (BOSC).

Design/methodology/approach

This paper uses a literature review of research articles from 1996 to 2007 with keyword indexes to survey the KM practice, KMS technology and its application in BOSC. Such keyword indexes include: BOSC, SCM, KM, KMS, expert system, knowledge‐based system and information system on the Elsevier online database, ScienceDirect, EBSCO, Proquest, Emerald, DOAJ, and Wiley Inter Science. A total of 1,500 articles were found but only 149 articles related to the keywords of KMS application and KM practices within SCM and BOSC.

Findings

The important findings indicate that the KMS application is solely focused on single knowledge problem for enabling individual SC members to attain operational excellence. There is a need for further research into the development of KMS with features of knowledge coordination that cross organizational borders in attaining the BOSC integration.

Research limitations/implications

Perhaps, the limitation of this study was the narrowness of the scope of the paper based on the keywords used for searching.

Practical implications

Validation of the multi‐disciplines of KM practices and KMS applications provides enterprises with useful guidelines for implementing KM‐ and KMS‐related projects within their current BOSC practices.

Originality/value

This paper provides useful knowledge by highlighting the characteristics of KMS technology within BOSC and empirical insights into the relationship between KM and BOSC practices.

Abstract

Purpose

In the process of the implementation of the eBologna program and the recent change of the university system, curricula at German universities have been redesigned; courses have been condensed and learning content has been re‐structured into modules, each of which requires an evaluation. Simultaneously, skills required for working in research and development changed; knowledge of mathematical or numerical algorithms and programming skills play an increasingly important role in the daily job routine of the working engineer. The purpose of this paper is to describe, implement and test a new course on numerical simulations along with a new software infrastructure, addressing this predicament.

Design/methodology/approach

To support learning by practical exercises, engineering faculties, the faculties of mathematics and physics, and the Computing Center of the University of Stuttgart setup a project for implementing an online programming lab for teaching the required skills. The focus of this project is to provide easy access to the necessary software tools, to avoid the overhead of installation and maintenance, and to seamlessly integrate these tools into the e‐learning infrastructure of the university.

Findings

Student evaluations showed a high acceptance of the project and the developed software is now well‐accepted and taken as a self‐evident part of the homework routine.

Originality/value

An online programming lab that integrates seamlessly into the e‐learning infrastructure of the university and is platform and system independent by following the established SCORM standard.

Abstract

Despite the rapid growth in the implementation of sophisticated software‐based control systems, today’s process industries still rely heavily on sensors and associated conditioning electronics to provide accurate data from the processes. While most instrumentation manufacturers have focused their attention on products and system software beyond such front end signal conditioning, Status Instruments have decided to invest in the design of a highly versatile front end conditioning module which can be adapted to meet an ever increasing number of applications simply by downloading a new piece of software from their Web site.

Abstract

Purpose

The purpose of this paper is to present the design and manufacture of embedded passive devices in organic substrates.

Design/methodology/approach

Low cost and high performance duplexers have been designed for WiMAX front‐end modules with multi‐layered organic substrates. Band‐pass filters (BPFs) and duplexers for the WiMAX FEM have been embedded in organic substrates. In addition, a new organic substrate manufacturing process has been proposed in order to improve the tolerance of embedded passives in organic substrates.

Findings

The overall size of FEM, which includes PA and bypass capacitor, is 5.4×4×1.5 mm. BPFs and duplexer show good electrical performances with low insertion loss and high attenuation. The dual‐band FEM with embedded passive components incorporates the duplexers including 2 and 5 GHz BPFs. The dimensions of BPFs and duplexer are 1.65×1.8×0.12 mm, 1.32×1.2×0.12 mm and 2×2×0.6 mm, respectively. The integrated dual‐band BPFs show an insertion loss < 1.8 dB in path band and 22‐40 dB attenuation performance in rejection band. The newly proposed fabrication process improves the tolerance for embedded capacitors in the organic substrate. This new process provides two main advantages. First, the flat coating process is not required. Second, it has a better copper pattern tolerance since the pattern is achieved with the addictive process. The tolerance of capacitances produced by the newly proposed process is compared with one manufactured by the conventional etching process. The newly proposed process provides a better capacitance tolerance.

Research limitations/implications

In future studies, it is suggested that the tolerance study should include other variations such as thickness, alignment and material properties.

Practical implications

The paper's findings can be used for designing and manufacturing embedded passives devices for wireless applications.

Originality/value

This study shows a technology development in the area of embedded passive devices in organic substrates.

Abstract

Purpose

There is no proposed solution to address the unresolved issues of constructing the Chinese university intellectual property information service system (IPISS) to promote the whole process service efficiency of IP creation, utilization, protection and management. The purpose of this paper is to propose a complete system, including theoretical framework and system development which addresses the existing difficulties to IP create, protect and transfer for researchers in universities. The paper shares the practice of utilizing the system developed by Wuhan University IP research team known as Wuhan University Intellectual Property Information Service System (WHU-IPISS).

Design/methodology/approach

First, the IPISS of 23 universities in China was investigated on the internet. Aiming at the deficiencies of the system, such as single service type, lack of patent display window, low management efficiency. This paper constructs the theoretical framework, proposes the IP ecological chain model, divides it into four sub-chains and carries on the functional design. Further, under the theoretical framework, the IPISS was developed, including the resource supply management system, user demand matching system, resource assessment system and expert support system. Finally, the system was applied to Wuhan University to provide IP services in the whole process for university researchers.

Findings

WHU-IPISS realizes the functions of IP resource supply, demand matching, value evaluation and expert support. It solves the IP needs of university researchers and provides a guarantee for their technology research, patent portfolio, patent transfer and patent rights protection. It also improves the efficiency of IP service and can construct the IP ecosphere in universities.

Originality/value

The WHU-IPISS solution resolves issues of “How to develop the university IP whole process service model, fulfilling the IP service needs for universities' researchers”. The software will be released as open-source for other universities' use. The publishing model is also useful for those universities that intend to implement the IPISS.

Abstract

Purpose

The purpose of this paper is to introduce a methodological approach to develop customized products which offer true customer value and achieve superior competitive advantage.

Design/methodology/approach

An integrated framework is presented where both front‐ and back‐end features of product development activities are illustrated. Detailed explanations of the framework participants are discussed with their specifications and view points that illustrate the value of the framework. This framework communicates between citarasa and do‐it‐yourself‐design configurators at the upstream, and available to promise, agile supply and demand network, advanced planning and scheduling systems in the downstream, in order to visualize the complete production scenarios and to maintain the flow of custom tailored product development.

Findings

It is hoped that the illustrated framework will bridge the gap between manufacturers, and customers in order to produce customer satisfied products that fulfill the business target in terms of earning more revenues.

Research limitations/implications

This research work is based on a theoretical hypothesis. Although the proposed framework is implemented in a truck manufacturing company, it requires application in more industrial organizations in order to generalize its effectiveness, suitability, and consistency in the manufacturing arena.

Originality/value

This paper outlines the configuration principle, along with different tools and methodologies, which support manufacturing firms in the customization of products in both upstream and downstream activities in a profitable way. These tools or methodologies can help product developers to improve their due‐date promising, exploitation of bottlenecks, and the visualization of their capability to produce the customers' specific products.
