Towards a Model-Driven IEC 61131-Based Development Process in Industrial Automation

The IEC 61131-3 standard defines a model and a set of programming languages for the development of industrial automation software. It is widely accepted by industry and most of the commercial tool vendors advertise compliance with it. On the other side, Model Driven Development (MDD) has been proved as a quite successful paradigm in general-purpose computing. This was the motivation for exploiting the benefits of MDD in the industrial automation domain. With the emerging IEC 61131 specification that defines an object-oriented (OO) extension to the function block model, there will be a push to the industry to better exploit the benefits of MDD in automation systems development. This work discusses possible alternatives to integrate the current but also the emerging specification of IEC 61131 in the model driven development process of automation systems. IEC 61499, UML and SysML are considered as possible alternatives to allow the developer to work in higher layers of abstraction than the one supported by IEC 61131 and to more effectively move from requirement specifications into the implementation model of the system.

Teaching Reform for Mobile Application Development with Industrial Projects,Double Instructors,and Automatic Assessments

Mobile Application Development is a well-known undergraduate specialized course majoring in Computer Science and Software Engineering.Since it is a rapid developing technique and requires extensive project samples to help understand,current teaching mechanism has still limitations in rare real project examples,outdated course contents,and lack of automatic assessment platforms.In order to improve the teaching effects and cultivate students’practical ability,we employ this teaching reform with industrial projects,double instructors,and automatic assessment platform to allow students participating in every course process.We aim to improve students’practical and collaboration ability during conducting the project spontaneously,and cultivate their awareness of self-learning and lifelong learning.Our classroom feedback has demonstrated that this teaching reform is effective on improving students’practical abilities,learning initiatives and comprehensive qualities.

A New Approach to Software Development Fusion Process Model

There are several software process models that have been proposed and are based on task involved in developing and maintaining software product. The large number of software projects not meeting their expectation in terms of functionality, cost, delivery schedule and effective project management appears to be lacking. In this paper, we present a new software fusion process model, which depicts the essential phases of a software project from initiate stage until the product is retired. Fusion is component based software process model, where each component implements a problem solving model. This approach reduces the risk associated with cost and time, as these risks will be limited to a component only and ensure the overall quality of software system by considering the changing requirements of customer, risk assessment, identification, evaluation and composition of relative concerns at each phase of development process.

A Reference Model for the Analysis and Comparison of MDE Approaches for Web-Application Development

The emerging Model-Driven Engineering (MDE) paradigm advocates the use of models as first-class citizens in the software development process, while artifacts such as documentation and source-code can be quickly produced from those models by using automated transformations. Even though many MDE-oriented approaches, languages and tools have been developed in the recent past, there is no standard that concretely defines a specific sequence of steps to obtain a functional software system from a model. Thus, the existing approaches present numerous differences among themselves, because each one handles the problems inherent to software development in its own way. This paper presents and discusses a reference model for the comparative study of current MDE approaches in the scope of web-application development. This reference model focuses on relevant aspects such as modeling language scope (domain, business-logic, user-interface), usage of patterns, separation of concerns, model transformations, tool support, and deployment details like web-platform independence and traditional programming required. The ultimate goal of this paper is to determine the aspects that will be of greater importance in future web-oriented MDE languages.

新质生产力推动科研服务地方经济社会发展的理论阐释及实践探索

科研服务地方是加快实施创新驱动发展战略、推进高质量发展、因地制宜发展新质生产力的应有之义。科研机构尤其地方科研机构及有地方特殊科学使命的单位、人员应是地方先进思想的倡导者、地方学术研究的开拓者、地方社会风尚的引领者、党在地方执政的坚定支持者。科研服务地方应坚持正确视角、遵循基本原则,议题有地方针对性。当前我国存在着评价体系不利科研为地方服务、地方科研脱离本地实际、地方性科研机构在地方发展或者决策中缺位或者议题不能聚焦于地方发展、地方特色的基础研究不够等问题,需要进一步统筹国家层面研究和地方层面研究,优化科研布局,合理配置资源,进一步提高科研服务地方的能力。

数字金融高质量发展的区域差异及社会嵌入补链研究

利用2011~2021年中国31省份数字金融数据,基于区域金融视角分析数字金融高质量发展的驱动作用机理,采用Dagum基尼系数对中国数字金融高质量发展的区域差异进行分解,发现存在非均衡的区域差异。进一步构建多层统计模型,对区域数字金融高质量发展差异驱动的结构性影响因素及“嵌入性”补链进行分析,结果显示:金融发展的区域地理、人口、产业分布、资本配置对数字金融高质量发展的影响显著,贡献率为80%;社会嵌入性结构、网络关系、认知、文化、政策等社会嵌入变量对数字金融高质量发展具有显著的直接或间接影响,贡献率为20%。据此认为“社会嵌入”是数字金融高质量发展的理想补链工具,且能较好地使数字金融的内生性与外在性融合。因此,要注重区域数字金融高质量发展的“社会嵌入”补链路径依赖逻辑,优化社会嵌入性因素对数字金融高质发展的影响,保障传统金融与区域数字金融高质量发展的有效对接补链。

新质生产力的知识产权驱动路径与制度协同

新质生产力发展依靠创新发挥主导作用,知识产权是建设与新质生产力相适应生产关系的制度载体。现有理论对新质生产力的范畴内涵尚未达成充分共识,导致关于新质生产力发展路径研究缺乏针对性。生产力以产业为载体,从产业结构转型需求出发,发展新质生产力不限于追求未来技术、颠覆性技术创新,根本上是对科技作为第一生产力的需求强化,既包括通过创新壮大战略新兴产业、培育未来产业,也包括推动传统产业转型升级。作为创新驱动发展的主要制度载体,知识产权通过双重路径驱动新质生产力发展:一是支撑建设科技创新的市场导向机制,二是衔接市场力量和国家战略科技力量,保障科技创新的新型举国体制顺畅运行。面向新质生产力的发展要求,知识产权需从供给、需求、环境三个维度作出制度协同,从而优化知识产权创造供给,提升知识产权保护效能,加强知识产权转化运用,深度参与知识产权全球治理,建设有利于新质生产力发展的国内外制度环境。
