Abstract
This paper introduces a generic performance measurement methodology for identifying and dimensioning the user requirements of laboratory information systems with a view to evaluating and improving their overall user satisfaction. The dynamic Web‐based laboratory information system (known as IntraMEL) for the Manufacturing Engineering Laboratories (MEL) in the City University of Hong Kong is used as a case study for formulating, testing and implementing the methodology. The proposed model takes an analytical approach to assess the performance of an information system using psychometric concepts. Through the experience gained from applying the methodology on IntraMEL, a set of performance evaluation guidelines can be established. These evaluation guidelines will be applicable to the information systems in other laboratories and service centres.

Abstract
Almost all industrial systems are distributed with multiple control points which interact to a limited extent, for which the idea of distribution of task at local (field) level is emerging. As locally‐based application tasks can reduce control delays, a fieldbus‐based smart and reliable DCS solution is recognised as a leader for real‐time industrial automation. Advanced control system has turned itself towards the implementation of digital distributed control systems (DCS) from centralised control systems. The phenomenon is becoming very popular because of its advantages over the whole operating system. Presents a case study for realising manufacturing systems (production lines) with fieldbus technology. The local operating network (LON) fieldbus system was chosen for this purpose because of availability of a wide range of products. Emphasises the reliability aspects of the control systems. A representative of a conveyor system, integrated with field devices, was conceived as the target platform.

Abstract
A flexible manufacturing system (FMS) is a complex manufacturing system and it demands a robust control software for its scheduling, planning and control functions. This paper describes the development of an agent‐based infrastructure for the control of a cellular FMS. The FMS in this project is a flexible assembly cell (FAC), comprising two assembly robots and a conveyor system. The aim is to establish a multi‐agent control system with good expandability and to be able to cope with dynamic changes in the FAC. The proposed agent‐based FAC control system comprises a collection of agents implemented in a distributed control network. The approach of the agent design is based on the object‐oriented modelling technique. According to the proposed control architecture, a standard agent template has been designed for the establishment of individual agents in the agent‐based system.

Abstract
Knowledge‐based timed colored object‐oriented Petri net (KTCOPN) is presented as a modelling method for a reconfigurable assembly system (RAS) in this paper. Compared to the conventional flexible assembly systems, the configuration of a RAS will allow flexibility not only in assembling a variety of products, but also in changing the system itself. Combining knowledge and object‐oriented methods into timed colored Petri net, allow the characteristic of RAS to be fully expressed. With object‐oriented methods, the whole system can be decomposed into concrete objects explicitly, and their relationship is constructed according to the system assembly requirements. Finally, a simple assembly system modeled by the KTCOPN is given.

Abstract
Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract
Since China initiated its “go global” policy that promotes its overseas investment, China’s Outward Foreign Direct Investment (OFDI) has increased almost twenty times during the last 10 years, reaching $55.9 billion in 2008. The issue of internationalization of Chinese OFDI has attracted increasing attention of researchers from a business perspective. This article systematically reviews the previous studies on overseas investments by Chinese MNEs and discusses the characteristics of Chinese internationalization behavior at both firm level and country level. The internationalization of Chinese companies cannot be understood as a simple game of “catch up” with established MNEs, and more firm‐level empirical studies should be carried out on how these characteristics influence firms’ strategic decisions.

Abstract
We examine the mode of international expansion as an equilibrium governance contract between home country and host country factor owner. The focus is on agency costs, a form of transactions costs. Two phenomena are shown to be related to the agency costs imposed by factor owners: (i) the choice of different modes of international expansion by one firm in different locations, and (ii) the simultaneous occurrence of several forms of foreign involvement in the same location. We attempt to characterize the dynamic relationship between the mode of an offshore operation and changes in factor market conditions that affect agency costs.

Abstract
Purpose
The purpose of this paper is to critically evaluate the state of the art of applications of organisational systematics and manufacturing cladistics in terms of strengths and weaknesses and introduce new generic cladistic and hierarchical classifications of discrete manufacturing systems. These classifications are the basis for a practical web-based expert system and diagnostic benchmarking tool.
Design/methodology/approach
There were two stages for the research methods, with eight re-iterative steps: one for theory building, using secondary and observational data, producing conceptual classifications; the second stage for theory testing and theory development, using quantitative data from 153 companies and 510 manufacturing systems, producing the final factual cladogram. Evolutionary relationships between 53 candidate manufacturing systems, using 13 characters with 84 states, are hypothesised and presented diagrammatically. The manufacturing systems are also organised in a hierarchical classification with 13 genera, 6 families and 3 orders under one class of discrete manufacturing.
Findings
This work addressed several weaknesses of current manufacturing cladistic classifications which include the lack of an explicit out-group comparison, limited conceptual cladogram development, limited use of characters and that previous classifications are specific to sectors. In order to correct these limitations, the paper first expands on previous work by producing a more generic manufacturing system classification. Second, it describes a novel web-based expert system for the practical application of the discrete manufacturing system.
Practical implications
The classifications form the basis for a practical web-based expert system and diagnostic benchmarking tool, but also have a novel use in an educational context as it simplifies and relationally organises extant manufacturing system knowledge.
Originality/value
The research employed a novel re-iterative methodology for both theory building, using observational data, producing the conceptual classification, and through theory testing developing the final factual cladogram that forms the basis for the practical web-based expert system and diagnostic tool.

Abstract
Based on the panel data analysis of Taiwan’s family business groups from 2000 to 2002, this research attempts to investigate the relationships among the types of ownership structure, particularistic ties, and the engagements in regional markets from a social capital perspective. The result indicates that a family business group’s use of particularistic ties is contingent on its relative centralization in decision‐making. Consequently, the family business group’s use of particularistic ties in subsidiaries significantly influences its engagements in regional markets. This study highlights the possible role of particularistic ties as a kind of firm‐specific advantage existing within family business groups when expanding internationally. Furthermore, it indicates that the indigenous particularistic ties intrinsic to Great China societies have implications for multinational companies in the context of this region.

Abstract
We examine whether firms’ multinationality leads to better performance and what the role of R&D investment is in the multinationality performance linkage. Unlike the previous studies, we employ both accounting‐ and market‐based measures of firm performance for a large sample of U.S. manufacturing firms. Our results show that the empirical relation between multinationality and performance is not monotonic but varies with the phase of a firm’s multinationality, starting with a negative relation initially, followed by a positive one, and then again a negative one. This horizontal S‐shaped curvilinear relation of multinationality is more pronounced for the market‐based performance measure and is supportive of the three‐stage theory of internationalization. We also find that a firm’s multinationality is related to greater firm performance when the firm possesses R&D investment, and that the effect of R&D increases with the extent of a firm’s multinationality. These results lend strong support for the Internalization theory and the resource‐based view of firms’ international expansion. Our results are robust to different model specifications with an alternative measure of multinationality.
