A Systematic Approach to the Design of Textile Processing Systems

为了响应客户对缩短交货时间和扩大产品范围的要求，美国的纺织工业已经转向需求激活制造。该项目将开发一种设计方法，将纺织加工机器配置成能够响应这些新需求的系统，并充分利用资本投资。本文提出的技术方法分为两部分：系统设计和性能分析。系统设计使用混合整数线性或非线性规划从可用的标准机器中选择和配置候选系统元素。对于性能分析，离散事件模拟将评估纺织加工系统的预测性能和成本。这种方法将导致成本最低的可行系统的选择，如：直接或部分经纱到梁上，纱筒的尺寸，模块化或传统织机等。除了纺织品之外，这种设备配置的设计方法在许多类型的制造系统中都是一个问题。在所有情况下，快速重组制造系统以满足不断变化的需求的问题是有趣的、现实的，并且具有很高的潜在回报。

This project will develop a design methodology to configure textile processing machines into systems that can respond to these new demands, as well as make the best use of capital investment. There are two parts to the proposed technical approach: system design and performance analysis. System design uses mixed integer linear or non-linear programming to choose and configure candidate system elements from standard machines that are available. For performance analysis, discrete event simulation will assess the predicted performance and cost of a textile processing system. The approach will lead to the lowest cost feasible system by making choices like: direct or sectional warping of yarn onto beams, size of a yarn creel, modular or conventional loom, etc. Such a design methodology for equipment configuration is an issue in many types of manufacturing systems, in addition to textiles. In all cases, the issue of quickly reorganizing a manufacturing system to meet changing demands is interesting, realistic, and has a high potential pay-off.
