Ontological approach for products-centric information system interoperability in networked manufacturing enterprises

Standardisation initiatives (ISO and IEC) try to answer the problem of managing heterogeneous information, scattered within organizations, by formalising the knowledge related to products technical data. While the product is the centred object from which, along its lifecycle, all enterprise systems, either inside a single enterprise or between cooperating networked enterprises, have a specific view, we may consider it as active as far as it participates to the decisions making by providing knowledge about itself. This paper proposes a novel approach, postulating that the product, represented by its technical data, may be considered as interoperable per se with the many applications involved in manufacturing enterprises as far as it embeds knowledge about itself, as it stores all its technical data, provided that these are embedded on a common model. The matter of this approach is to formalise of all technical data and concepts contributing to the definition of a Product Ontology, embedded into the product itself and making it interoperable with applications, minimising loss of semantics.     

An ant colony optimization approach to multi-objective optimal design of symmetric hybrid laminates for maximum fundamental frequency and minimum cost

An ant colony optimization algorithm for optimum design of symmetric hybrid laminates is described. The objective is simultaneous maximization of fundamental frequency and minimization of cost. Number of surface and core layers made of high-stiffness and low-stiffness materials, respectively, and fiber orientations are the design variables. Optimal stacking sequences are given for hybrid graphite/epoxy-glass/epoxy laminated plates with different aspect ratios and number of plies. The results obtained by ant colony optimization are compared to results obtained by a genetic algorithm and simulated annealing. The effectiveness of the hybridization concept for reducing the weight and keeping the fundamental frequency at a reasonable level is demonstrated. Furthermore, it is shown that the proposed ant colony algorithm outperforms the two other heuristics.     

The cost of approximate controllability for semilinear heat equations

We consider the semilinear heat equation with globally Lipschitz non-linearity involving gradient terms in a bounded domain of R^n. In this paper, we obtain explicit bounds of the cost of approximate controllability, i.e., of the minimal norm of a control needed to control the system approximately. The methods we used combine global Carleman estimates, the variational approach to approximate controllability and Schauder＇s fixed point theorem.     

基于Web应用的工资管理系统

随着企业管理信息化、透明化和Internet应用的普及,基于Web的应用系统也得到了人们的亲睐。通过Web应用,工资管理系统的开发,人们可更好的共享资源和实时的查看自己的工资情况。对信息的获取不再受时间和地点的限制,也能实时的反馈自己的意见,这样对于管理员来说也就极大地降低了工作量,使工资管理更加科学化,业务操作更加透明。该系统的开发主要包括前端的有关应用程序的开发以及后台的数据库的建立、维护两个方面的内容,系统的建立和维护主要要求其管理数据的系统性、规范性、自动性等特点,而前台的应用程序开发则要求做到各项功能完备、操作简便、易学易用。综合上述要求,首先分析了企业工资管理系统的应用现状,阐述了工资管理系统的开发目的。系统开发工具的选择确定了系统的开发平台．然后给出了系统的详细设计和数据库设计。
