Dynamic grey model of verification cycle and lifecycle of measuring instrument and its application

Two dynamic grey models DGM (1, 1) for the verification cycle and the lifecycle of measuring instrument based on time sequence and frequency sequence were set up, according to the statistical feature of examination data and weighting method. By a specific case, i.e. vernier caliper, it is proved that the fit precision and forecast precision of the models are much higher, the cycles are obviously different under different working conditions, and the forecast result of the frequency sequence model is better than that of the time sequence model. Combining dynamic grey model and auto-manufacturing case the controlling and information subsystems of verification cycle and the lifecycle based on information integration, multi-sensor controlling and management controlling were given. The models can be used in production process to help enterprise reduce error, cost and flaw.

A Novel Lifecycle Model for Web-based Application Development in Small and Medium Enterprises

Software engineering＇s lifecycle models havc proven to be very important for traditional software development. However, can these models be applied to the development of Web-based applications as well？ In recent years, Web-based applications have become more and more complicated and a lot of efforts have been placed on introducing new technologies such as J2EE, PhP, and .NET, etc., which have been universally accepted as the development technologies for Web-based applications. However, there is no universally accepted process model for the development of Web-based applications. Moreover, shaping the process model for small medium-sized enterprises （SMEs）, which have limited resources, has been relatively neglected. Based on our previous work, this paper presents an expanded lifecycle process model for the development of Web-based applications in SMEs. It consists of three sets of processes, i.e., requirement processes, development processes, and evolution processes. Particularly, the post-delivery evolution processes are important to SMEs to develop and maintain quality web applications with limited resources and time.

Strategy Approach towards Product Lifecycle Management

Mass Customization and global economic collaboration drives the product development and management beyond internal enterprise to cover the whole product value chain. To meet such requirement, a strategy approach focusing on data organization for product lifecycle management was promoted. The approach takes product platform as the base, view engine and rule-based access as data access mechanism, and integration and collaboration bus as a enabler to allow participants involved in product lifecycle to get convenient, WEB-based access to the internal and external content, applications, and services.

On the Design of Effective E-Commerce Applications: An ISO-Based Lifecycle Model

The provision of services as e-commodities and the wide use of networked business models have driven buyer experience to new heights. Innovation, coupled with quality is the competitive advantage e-commerce vendors strive to achieve when designing or re-designing their software. In terms of quality, evaluation stood in the spotlight for many years. However, software analysis and design based on quality models have been used mostly for understanding, rather than improving. In this work, we present a new model for the analysis and design of e-commerce software systems mapped to the software life-cycle process. Quality control procedures are mapped to every phase, from initiation and design to delivery. Based on current ISO standards such as ISO25000 series, this work discusses technical and managerial principles that need to be applied in order to obtain quality e-commerce software.

Overview of the Analytical Lifecycle of Supercritical Fluid Chromatography Methods

In recent times, the overall interest over Supercritical Fluid Chromatography (SFC) is truly growing within various domains but especially for pharmaceutical analysis. However, in the best of our knowledge modern SFC is not yet applied for drug quality control in the daily routine framework. Among the numerous reported SFC methods, none of them could be found to fully satisfy to all steps of the analytical method lifecycle. Thereby, the present contribution aims to provide an overview of the current and past achievements related to SFC techniques, with a targeted attention to this lifecycle and its successive steps. The included discussions were therefore structured accordingly and emphasizing the analytical method lifecycle in accord with the International Conference on Harmonisation (ICH). Recent and important scientific outputs in the field of analytical SFC, as well as instrumental evolution, qualification strategies, method development methodologies and discussions on the topic of method validation are reviewed.

Research on Lifecycle-Oriented Open Framework of Fault Diagnosis for Equipment System

Based on the analysis of the whole lifecycle of equipment, we, in this paper, propose the lifecycle-oriented diagnosis and maintenance philosophy, and expound its connotation and characteristics. Then, we present its open framework of the lifecycle-oriented diagnosis view in detail, which consists of three levels： information model, net model and open space. The open space level indicates the alternation of the information, the integration of the structure and the modeling of the knowledge. These three levels reveal the synthesis of the diagnosis process effectively in length and breadth. Finally, the main work of the paper and the future work on this problem are discussed.

董事会断裂带、内部控制与审计质量——基于制造业上市公司的数据

断裂带的存在极容易使董事会形成不同的子群体,而子群体间的相互作用又会反向牵制和干扰董事会的监督能力,进而影响审计质量。以2013—2021年中国沪深A股制造业上市公司为样本,探究董事会断裂带对审计质量的影响。研究发现:首先,董事会断裂带与审计质量呈倒U形关系,断裂带异常会干扰公司董事会监督职能的正常发挥,从而影响审计质量;其次,董事会断裂带与审计质量的倒U形关系主要源于任务导向断裂带的作用,在企业成熟期更为显著;最后,内部控制能够削弱董事会断裂带对审计质量的影响,而良好的内部控制有助于缓解股东与管理层的代理成本,弥补董事会子群体间冲突带来的负面影响,在合理范围内有效地提升审计质量。
