一种基于语法的供应链流程定义元模型

在供应链流程建模和描述的方法体系中,语法建模方法是最新出现的一种很有发展潜力的建模语言,与其它建模方法相比具有多方面的优越性.供应链流程定义语言(SCPDL,supply chain process definition language)作为一种新的供应链流程建模方法,是供应链流程与语法模型的转换器,它可使供应链流程转化为相应的语法模型,以便在系统上实现对流程的查询、管理等逻辑处理,并进一步实现了不同方法描述的供应链流程之间的便利转换.通过对流程定义语言的深入研究,融入最新的过程语法建模和协调理论的相关理念,提出了一个基于语法的供应链流程定义元模型.并在此基础上采用XML(eXtensible Markup Language)对其规则进行重写,形成了基于XML的供应链流程定义语言.提出的XSCPDL(XML SCPDL)模型方法将使供应链管理的建模、管理和优化工具与供应链流程引擎之间实现相互转换,并便于不同软件开发商提供的流程模型在XML的平台上进行快速交互.

浅谈企业运营中流程的管理

二十一世纪世界经济趋于全球化,企业间的竞争日趋激烈。企业在更大的挑战面前如果没有危机感,提高管理意识将面临着失去生存空间的境地。在企业运营中如何才能提高管理效率,让有限的资源发挥最大的作用呢?答案其实并不复杂:只要提纲挈领抓住问题的实质,即流程的运行。以A轴承公司为例,分析企业流程的较为流畅的运行状态。流程分为三类:管理流程、运作流程、及支持流程。每类流程的运营原理是一致的,都是以满足客户需求为目的;都是从基础做起:首先将流程标准化,然后再对其进行管理。流程标准化分为四步:确定流程的主人和团队,可视化流程图,确立流程的目标和量化标准,定义流程"仪表盘"。流程管理同样分为四步:重要输入的控制计划,定期回顾流程的绩效,收集客户的需求,流程改善团队的活动。流程的运行是个系统工程,它将供应商、本团队、客户有机的联结在一起。他是需要团队很好的合作才能达成目标。A公司在此做出了很大的努力,所以才会有公司整体绩效的优异表现。

Cinderella purchasing transformation: linking purchasing status to purchasing practices and business performance

This paper contributes to the on-going debate about the relevance of the purchasing function for the firm value creation. We empirically examine the role of the purchasing function in improving business performance through an international survey based on 653 responses. Results suggest that purchasing practices related to spend rationalisation have a positive impact on the overall business performance, whereas supplier development & integration and sustainable purchasing have not. Moreover, the purchasing recognition by top managers and other organisational units emerge as a powerful antecedent of all purchasing practices. Instead, pure formal authority provided by the position in the organisation chart (i.e. the report level) does not have any influence on purchasing practices adoption.     

A human - computer interactive approach based on activity - section analysis for BPR

In any business process reengineering (BPR) project, a thorough understanding of various tasks and activities of the organization is required. Very often this idea is captured using a simple flow chart or static representation diagram. The weakness here is that the process design complexity is not adequately represented by the use of flow charts, and this allows for limited human-computer interaction during the process design and analysis. In this paper, we propose an enhanced flow chart approach; the concept of activity-section flow chart to support BPR, which is a combination of the existing activity flow chart and section flow chart. Using this approach, a human-computer interactive model for BPR is developed. This model can identify the unreasonable activity loops and excessive business rounds between sections by the adjacent and reachable matrices. Via the human-computer interaction, the process can be revised by human experience. This approach provides an efficient tool for BPR of large-scale systems. It has been applied to the material supply management system of an iron and steel works, and satisfactory results have been achieved.     

Bursts and heavy tails of execution time in business processes

This paper investigates the phenomena and effects of heavy tails of execution time in business processes. We approached the heavy tails as a particular variation of business process execution, and analysed them from empirical data of its execution time. The features and possible causes of the heavy tails were investigated. A workflow simulation was conducted to simulate the heavy tails, in order to evaluate quantitatively their effects to business process performance. The simulation outcomes demonstrate that (1) even a heavy-tailed activity in a business process can cause large variation of end-to-end execution times of the process and (2) there are significant prediction gaps resulted by different assumptions of execution times between an exponential distribution and a heavy-tailed distribution.

Business process re-engineering the supply chain

Common foundations which underlie thinking in the supply chain management (SCM), Business process re-engineering (BPR) and business process improvement (BPI) philosophies are highlighted. The view that BPR is a new concept is argued against by highlighting die work performed in other fields, namely SCM from the systems perspective. It is argued that those who have already implemented the SCM philosophy will have already travelled the same path as BPR and indeed re-engineered their own processes. Once businesses have integrated their supply chain the greatest benefits will have already been achieved, however system dynamics analysis does show significant on-cost differences dependent on the redesign strategy implemented. A generic structured model for SCM is enhanced through this comparison with BPR with the following characteristics being added; do not be afraid to be radical with respect to internal integration and continually search for step change improvement ideas which can be strategically phased in to positively impact the marketplace.

Exploring the impact of sustainable value proposition on firm performance

Considering the immense potential of sustainable business models in tackling the broader challenge of corporate sustainability, this paper integrates the literature streams on sustainability practices and organizational business models to analyze the performance implications of a firm's sustainable value proposition. Based on the analysis of a large panel dataset across different industries, consistent with the proposed theory, a sustainable value proposition has been found to have a positive impact on a firm's market-based financial performance (namely, Tobin's Q). Yet, this impact turns out to be highly context-dependent. In particular, the findings reveal that a firm's R&D capabilities improve the positive effect of a sustainable value proposition on a firm's financial performance. At the same time, the marketing communication capabilities and sustainable practices regarding employee relations reduce the sustainable value proposition's financial performance effect, arguably due to the costs associated with marketing and the loss in employee interest during the process of adopting the sustainable business model elements.     

E-business services and business performance: a study of the telecommunications manufacturing industry

The development of information and communication technologies has significantly changed the business interactions as well as created new approaches for improving business performances. While the benefits from this development have been well documented in the literature, it also poses a significant challenge for companies in tracking or further improving e-business services. This article contributes to this body of knowledge by investigating the impact of e-business service dimensions on business performance in the telecommunications manufacturing industry. Based on 121 usable responses from a questionnaire survey of the UK telecommunication manufacturers, structural equation modelling is employed to identify the main e-business service dimensions which affect business performance significantly. The data analysis reveals that two e-business service dimensions significantly influence suppliers’ performance from the buyer's perspective. It also indicates the significant relationships between suppliers’ performance, buyer-perceived buyer–supplier relationship maintenance and the buyer's competitive advantage. The findings in this research not only help the supplier to understand which practices significantly improve its overall performance (as perceived by the buyer), but also assist the buyer in its supplier development efforts to improve its own business performance.
