The Lambda Library: unnamed functions in C++

The Lambda Library (LL) adds a form of lambda functions to C++, which are common in functional programming languages. The LL is implemented as a template library using standard C++; thus no language extensions or preprocessing is required. The LL consists of a rich set of tools for defining unnamed functions. In particular these unnamed functions work seamlessly with the generic algorithms in the C++ Standard Library. The LL offers significant improvements, in terms of generality and ease of use, compared to the current tools in the C++ Standard Library. Copyright © 2003 John Wiley & Sons, Ltd.     

Automatic generation of IDEF0 models

This paper looks into a new area for knowledge-based system application, that of manufacturing modelling. Manual generation of IDEF0 models of manufacturing systems is time-consuming and inconsistent. However, the process can be automated to improve timeliness and consistency. In this paper, a knowledge-based manufacturing modelling system for the automatic generation of IDEF0 models is proposed. The system will not only greatly reduce the IDEF0 modelling time but will also eliminate the inconsistency problem of conventional IDEF0 modelling systems. The paper explains the knowledge-based approach and identifies the kinds of domain knowledge that are required for the construction of the knowledge-based manufacturing modelling system.

An XML-based approach to represent generic bill of materials

To solve the difficulty in describing the generic bill of material (GBOM) with the conventional tabular structure in a relational database system,a novel XML-based approach is presented to represent GBOM. It can represent and maintain one generic structure that encompasses all variants of a product. With the combination of product-oriented notation,this approach further gives a high degree of flexibility to support the user in the product variant specification task. The generic BOM system is then introduced for the particular product variant,and a prototype system has been developed. It is indicated that the presented approach is feasible.     

新的捷联惯性导航划桨误差补偿算法

针对实际捷联惯性导航系统解算中的圆锥误差和划桨误差,结合已解算出的当前时刻之前两个周期的姿态信息对旋转矢量进行修正的算法,利用算法的对偶性原理,将该算法应用于划桨误差补偿算法中。在划桨运动下对该算法进行了仿真,仿真结果表明,该划桨误差补偿算法具有与解析解相当的精度。     

复杂产品共性技术研发的政府最优成本补贴

为发挥政府资助的最优杠杆作用,探究政府在复杂产品共性技术研发中最优成本补贴,从政府分担研发成本的角度,运用博弈模型构建了一个主制造商与一个供应商协同研发、政府扶持下的共性技术研发成本分摊模型,并分析求解了Nash非合作博弈和合作博弈下的政府研发成本最优补贴比例以及主制造商、供应商的最优物质性成本投入,最后基于所构建的模型进行了算例分析。研究表明,复杂产品共性技术的"共性度"和产品复杂度与政府对主制造商和供应商补贴比例成正比,主制造商供应商的物质性成本投入与政府的补贴比例成正比,其研发成果带给主制造商和供应商的利润也与政府补贴比例成正比。
