Relationship between just-in-time manufacturing practices and performance: A meta-analytic investigation

Just-in-time (JIT) manufacturing is among the most commonly researched topics in the area of operations management. This study examines the relationship between JIT manufacturing practices and performance outcomes by means of meta-analysis of correlations approach. Based on an in-depth analysis of literature spanning from 1992 to 2008, the results of this meta-analytic investigation support a positive relationship between JIT manufacturing practices and aggregate performance. However, the findings suggest that not all individual JIT practices are associated with all types of performance outcomes. This study highlights the JIT practices that have the greatest impact on individual performance outcomes and emphasizes the role of moderating factors in the relationship between JIT practices and performance. Theoretical and managerial implications are discussed and directions for future theory building in JIT are presented.

Comparative study on the relationship between just-in-time production practices and operational performance in manufacturing plants

This study analyzes the differences in approaching JIT production across countries in order to identify alternative paths to high manufacturing performance. We applied ANOVA and regression techniques to the database of High Performance Manufacturing Project to examine the similarities and differences across countries in JIT implementation and the effect of JIT production practices on operational performance. The results indicated that JIT production practices were implemented in different ways across the countries. We found that the relationship between JIT production practices and plant performance is contingent on the national context and infrastructure practices in quality and workforce management. JIT delivery by suppliers, JIT layout, and setup time reduction were found to be the most effective approaches to improve cost, delivery, and flexibility. This study highlights the important role of shop-floor communication and information sharing, which should be focused for maximizing the benefits of JIT implementation.

JIT采购方式对公司净现值的影响

本文通过分析比较JIT采购方式与传统采购方式的不同,得出JIT采购方式的优点,并得出其对公司净现值增值的积极影响。原料采购是企业全部经营活动的起点,这一环节对企业整体经营活动效率的提高非常重要。JIT采购方式是上世纪七十年代由日本丰田集团创造的一种新型的管理方法,在西方发达国家受到了普遍重视,并在实践中取得了良好的效果。目前我国有很多企业正逐步意识到这种管理方法的先进性,并开始把这种管理思想应用到企业价值链的各个环节中去。由净现值公式NPV=-C+PV,我们可以得出JIT采购方式通过使企业最大限度地降低成本,使企业净现值增加,使企业价值增值。     

Just-in-time inventory systems innovation and the predictability of earnings

Firms that adopt just-in-time (JIT) inventory practices do so in order to realize cost savings and improve product quality, but an unexpected benefit to such firms could be a more predictable earnings stream. We examine the relationship between implementation of just-in-time inventory practices and the predictability of future quarterly earnings for a matched-pair sample of 82 firms, half of which have publicly announced that they have adopted JIT inventory practices. We find that one- and four-step-ahead forecasts of quarterly earnings, using either a Brown–Rozeff [Journal of Accounting Research (1979) 179–189] ARIMA or a seasonal random walk expectation model, are more accurate for the firms that have adopted JIT.

Modeling the Impacts of Corporate Commitment on Climate Change

The aim of this paper is to propose an integrative framework for understanding the determinants of business strategies to reduce greenhouse gas emissions and the impact of these determinants on performance. The proposed structural equation model is based on a survey of 319 Canadian manufacturing firms. The study calls into question the traditionally positive relationship between a firm's environmental commitment and its economic motivations. However, the results also show a win–win relationship between the commitment to reduce greenhouse gas emissions and financial performance. This study contributes to the understanding of the motivations underlying the efforts manufacturers make to tackle climate change and their economic benefits.

The production performance benefits from JIT implementation

The intense competition in the current marketplace has forced firms to reexamine their methods of doing business. The US manufacturers have struggled with growing trade deficits and outsourced operations, while strong market competitors have emerged, using superior manufacturing practices in the form of just-in-time (JIT) and continuous process improvement. Although proponents cite the many benefits of JIT adoption, its implementation rate in the US has been relatively conservative. This study uses survey responses from executives at 95 JIT-practicing firms to better understand the benefits that firms have experienced through JIT adoption, and whether a more comprehensive implementation is worthwhile. The research results demonstrate that implementing the quality, continuous improvement, and waste reduction practices embodied in the JIT philosophy can enhance firm competitiveness. JIT implementation improves performance through lower inventory levels, reduced quality costs, and greater customer responsiveness. This study indicates that JIT is a vital manufacturing strategy to build and sustain competitive advantage.     

Efficient approach to health care industry material resource management: an empirical research

The feasibility of JIT implementation in the health care industry was examined through in-depth case studies and survey research. Specifically, this research examined two different groups in the health care industry: health care institutions that have introduced JIT philosophy into their operations and those that have not. Based on this classification, the research reveals the different impacts that the introduction of JIT philosophy has had on the health care industry's inventory management, service quality, and competitiveness. According to the research result, the introduction of the JIT philosophy in the health care industry's material management system improved that system and reduced implementation problems even though the differences between the JH and the NJH were not high. However, this research found that great potentials exist for the successful implementation of JIT philosophy for material management even though most of the JIT in the health care industry is still in its early stages. Moreover, with the maturing of the stockless material management system, differences between the JH and the NJH groups will be even more significant.     

汽车制造行业零部件仓储与配送WPSPI模式研究

汽车制造行业目前普遍采用以主机厂为核心的JIT生产模式,但在JIT模式具体应用的过程中由于种种原因并没有实现在整个供应链内消除库存,大多数情况下只是实现了库存从主机厂向供应链供应商的转移,这种转移无疑增加了供应商的仓储库存成本,鉴于上述情况经过对某大型汽车制造企业上游供应链典型企业的研究,提出了全过程货架托盘一体化物流模式(简称WPSPI,即Whole Process goods Shelf&Pallet Integration模式),该模式旨在减少供应链物流中的包装转换及对仓储设施的购置费用,同时实现整个供应链物流效率的提高和物流成本的降低。     

Just-in-time: maximizing its success potential

The effective implementation and use of JIT manufacturing practices depends largely on the education, training, and commitment of all levels of management to a fundamental quality-first policy. Management must transfer and demonstrate that commitment to every level and extension of the manufacturing endeavor. As a company establishes and reaches toward that goal, the move to JIT manufacturing practices becomes rational and justifiable. Failing to establish and commit to a quality directive greatly diminishes the potential benefits of JIT. If all levels of manufacturing participate in the JIT planning, implementing, and maintenance procedure, the realization of positive change and improvement drives the process. Total participation makes the task of JIT implementation not only possible, but practical. Enhanced mutual respect for all concerned is a likely consequence, advancing the productive environment.

Assessing the impact of JIT using economic theory

This paper combines ideas that are well founded in the production and inventory management literature, with analytical approaches that have been long established in the economic theory literature, to reveal and explore production-function characteristic differences between JIT producers and non-JIT producers among electronic firms in Ontario, Canada. The methodology employed is the estimation of the CES-TL total cost system. Our primary conclusion is that JIT firms are more cost-efficient and appear to be distinct from the non-JIT group. This conclusion is supported by: (1) the fact that, in most cases, the elasticities calculated from the two groups of firms are significantly different; (2) the fact that the cost elasticity with respect to output is lower for the JIT firms than for the non-JIT firms, indicating that the former are better able to capture economies of scale and density; (3) the difference between the elasticities of factor productivity, with respect to output changes, shows the JIT firms as being more labor- and materials-saving than the non-JIT firms.
