Research on pricing,service and logistic decision-making of E-supply chain with‘Free Shipping’strategy

Considering the cost of logistic service and the‘Free Shipping’strategy,two models of E-supply chain,respectively dominated by e-commerce platform or manufacturer are constructed,and the optimal decisions for each model is calculated in this paper.The research indicates that:the sales price is lower and the profit of manufacturer is higher in the mode dominated by manufacturer.On the other hand,the platform’s service-level is lower and the profit of platform is higher in the mode dominated by dominant platform.Further,the sales price,platform’s service and platform’s profit will increase with the growth of commission and decrease with the service cost elasticity coefficient.Contrarily,the profit of manufacturer will decrease with the growth of commission but increase with elasticity coefficient.And,the logistic price and profit of logistic enterprise are higher in the mode dominated by manufacturer,moreover,they will decrease with the growth of commission.

基于Delphi的Free!ship二次开发初探

Free!ship软件以其功能强大、界面友好以及免费使用等优势得到广泛应用。对船舶初步设计的工作而言,希望在完成线型设计前,该软件也能对主尺度进行确定,而Free!ship现有功能还不能满足这一要求。为此利用Free!ship提供的二次开发环境,在Free!ship2.6版本原有功能的基础上,对软件进行二次开发。以主尺度优化模块及用Delphi编程确定添加灵便型油轮主尺度为例,提出了开发的方法及步骤,为进一步的研究和开发该软件提供了基础。

基于Web的船型变换系统研究

在对系统功能进行总体分析的基础上,采用SQL Server 2005建立了系统所需的船型数据库。使用ASP.NET技术和集成开发工具Microsoft Visual Studio 2008,选用C#为编程语言,调用船舶设计软件Free!ship开发了基于Web的船型变换系统。研究结果表明,该系统可以方便快捷地生成船体型线,加速船舶设计进程,实现船型数据共享。

高强轻舟结构设计及试验应用研究

运用船舶设计软件Free!ship进行主尺度设计,运用同济曙光有限元正反分析软件进行应力分析,运用Adobe Photoshop CS2中文版软件进行图像扫描、编辑修改、图像制作、,图像输入与输出,运用AutoCAD 2007中文版软件进行二维绘图、绘制、设计文档,分析高强轻舟界面应力分布,计算轻舟的理论最大排水量、预期排水量、表观密度等;采用轻质高强纯无机胶凝材料,进行先外模后内模的施工工艺,制作出长6m,厚度12mm、表观密度为1800kg/m3的大跨度轻质高强水泥轻舟。
