New production models: A strategic view

In spite of the recognized crisis of the Fordist production paradigm, the emerging paradigm has not yet been clearly defined but only interpreted by several 'production models' (Lean Production, World-Class Manufacturing, etc.). Furthermore, these are rarely considered as linked to both the corporate and manufacturing strategies. An effort is made here to link the traditional and emergent 'strategic management' dictates and then to interpret the contents of manufacturing strategy. Because of this framework, a collocation of the various production models is proposed. In particular, these production models--in the ambit of 'operations management'--can be seen as different emphases on the main constituent elements of a framework that seeks to unify traditional and emergent 'strategic management' dictates.     

Empirical study of the relationship between operations strategy and information systems strategic orientation in an e-commerce environment

Many corporate executives are convinced that today's e-commerce operations require a fundamental review of business strategy. Operations management researchers also call for substantiating operations strategy research to an e-commerce environment. However, no empirical research has explored information systems strategic issues using operations strategy theory. Drawing on both operations strategy and the information systems strategy literature, this exploratory research proposes a conceptual framework integrating both operations strategy and information systems strategy models, and then applies this new proposed framework to an e-commerce setting. This research not only provides a conceptual framework systematically to explore e-commerce strategic issues, but also provides empirical evidence on the relationships between its various constructs. Results of this exploratory study indicate that the business environment appears to have a tangible impact on strategic choices in operations. It also appears that links between the business environment and operations strategy in e-commerce, as well as the alignment between the information systems strategic orientation and operations strategy, determines e-commerce business performance success. Results show that high-performing e-commerce companies and low-performing e-commerce companies use different information systems strategies to support their operations strategy. The types of strategies these companies use are identified in this study.     

公司治理视角下基于VPRS的公司经营困境预警

从公司治理的角度,构建了一套比较全面的综合预警指标体系。以2006-2009年首次被ST的160家上市公司及其配对公司作为研究样本,基于变精度粗糙集理论(VPRS),分别构建仅包含财务指标和包含所有指标的上市公司经营困境预警模型。通过理论分析和实证研究发现:健康公司和困境公司在早期的公司治理方面就存在着显著差异,晚期差异逐渐减小;加入公司治理变量后的变精度粗糙集模型的预测精度得到了提高;仅包含财务数据的模型在经营困境的晚期预测精度较高,早期预测效果不佳;对早期预测来说,包含财务指标和公司治理指标等多方面因素的模型更加适合。     

The Effect of Corporate Political Activity on MNC Subsidiary Legitimacy: An Institutional Perspective

MNC subsidiaries engage in a variety of corporate political activities to gain legitimacy in the host country. Based on institutional theory, our study examines five types of strategies that MNC subsidiaries pursue to gain legitimacy in foreign markets. Using data from Australian subsidiaries of MNCs operating in different industries, and whose parents originate from 28 different countries, we find that mimetic isomorphism strategy has the strongest effect whereas information strategy has no effect on subsidiary legitimacy. The other three strategies, namely, financial, constituency building and relational have strong to moderate effects on subsidiary legitimacy. In addition, we show that multiple CPA strategies are essential and work together synergistically to contribute to the legitimacy of MNC subsidiaries. Our paper provides empirical support to the widely recognized need for MNC subsidiaries to engage in different types of CPA to legitimize their operations in diverse institutional contexts across the globe.

Hybrid modelling of MTO/ETO manufacturing environments for performance assessment

Performance assessment is critical in today’s competitive environments, where companies need to establish trade-offs between key competitive dimensions. The complexity of these environments calls for new approaches to performance assessment. Thus, in this work, we propose a novel conceptual framework for performance assessment in manufacturing environments combining different production strategies. Focus is laid on MTO/ETO combined environments and a three-stage problem analysis is considered. Firstly, a hybrid SD-DES-ABS model approach addresses the needs of a system that handles different types of orders, processes and workforce allocation requirements; secondly, the model results for different demand scenarios are assessed using a one-way ANOVA analysis followed by a Tukey – Kramer’s test, with pairwise comparisons for assessment of significant performance variations under different system operating policies. A full factorial Design of Experiments (DOE) analysis follows, for determining the relevant process parameters influencing the system performance. As an example of application of the proposed framework, we consider the case of an advanced manufacturing company, whose manufacturing environment encompasses combined MTO/ETO production strategies.     

Aligning workload control theory and practice: lot splitting and operation overlapping issues

This paper addresses the problem of lot splitting in the context of workload control (WLC). Past studies on WLC assumed that jobs released to the shop floor proceed through the different stages of processing without being split. However, in practice, large jobs are often split into smaller transfer sublots so that they can move more quickly and independently through the production process and allow operations overlapping relating to the same job. This paper assesses the performance of different lot splitting policies for job release and dispatching strategies under lot splitting. A new dispatching rule was designed to specifically take advantage of lot splitting and operations overlapping in the context of WLC. Discrete-event simulation is used to assess system performance in relation to the ability to provide shorter delivery times and on time deliveries. Results highlight the importance of releasing the sublots of the same job together and demonstrate that combining an effective lot splitting policy with an appropriate dispatching rule can enhance the performance of production systems.     

Loading and control policies for a flexible manufacturing system

An experimental investigation of operating strategies for a computer-controlled flexible manufacturing system is reported. The system is a real one, consisting of nine machines, an inspection station and a centralized queueing area—all interconnected by an automatic material-handling mechanism. The operating strategies considered involve policies for loading (allocating operations and tooling to machines) and real-time flow control. A detailed simulation was employed to test alternatives. The results are different from those of classical job shop scheduling studies, showing the dependence of system performance on the loading and control strategies chosen to operate this flexible manufacturing system. Loading and control methods are defined that significantly improve the system's production rate when compared to methods which were previously applied to the system. Finally, some conclusions are presented concerning the control of these automated systems.     

Corporate entrepreneurship,operations core competency and innovation in emerging economies

This study used a blended view of corporate entrepreneurship and operations core capability as enablers of innovation. Survey data collected from automotive OEM suppliers in five emerging countries in South-east Asia are used to examine the relationships among corporate entrepreneurship, operations core competency and innovation. We measured corporate entrepreneurship by its corporate culture and leadership, whereas operations core competency was operationalised by a firm’s knowledge management, technology management and process management. Finally, innovation is measured by process innovation and product innovation. Our analyses show that in the context of Asia, corporate entrepreneurship affects a firm’s operations core competency, which in turn affects innovation. Our findings provide valuable insights about the enablers of a firm’s operations core competency and innovation.
