Scheduling Optimization Modelling: A Case Study of a Woven Label Manufacturing Company

Production scheduling involves all activities of building production schedules, including coordinating and assigning activities to each person, group of people, or machine and arranging work orders in each workplace. Production scheduling must solve all problems such as minimizing customer wait time, storage costs, and production time; and effectively using the enterprise’s human resources. This paper studies the application of flexible job shop modelling on scheduling a woven labelling process. The labelling process includes several steps which are handled in different work-stations. Each workstation is also comprised of several identical parallel machines. In this study, job splitting is allowed so that the power of work stations can be utilized better. The final objective is to minimize the total completion time of all jobs. The results show a significant improvement since the new planning may save more than 60% of lead time compared to the current schedule. The contribution of this research is to propose a flexible job shop model for scheduling a woven labelling process. The proposed approach can also be applied to support complex production scheduling processes under fuzzy environments in different industries. A practical case study demonstrates the effectiveness of the proposed model.

A model of seam pucker and its applications Part I: theoretical

Abstract

This article considers a simple model of the lock stitch (301) seam, and uses it to derive a measure of the severity of puckering in the seam. The numerical value of the measure depends on the bending properties of the fabrics and thread in the seam, together with the tensions in the threads. How the latter may be estimated is discussed.

论服装款式设计与结构设计

任何事物都处于一个有机的系统之中,脱离系统或整体而谈论某个组成部分,都会使其失去最根本的意义,容易走入误区。本文着重分析不能孤立地谈论服装款式设计,而是要在把握全局的基础上,强调款式设计和结构设计并重的观点,并着重论述服装结构设计的重要性。     

使用AutoCAD的AutoLISP语言进行服装衣片的计算机辅助绘图与设计

研究了使用ＡｕｔｏＣＡＤ和ＡｕｔｏＬＩＳＰ语言中进行服装衣片的计算机辅助绘图与设计的方法。文中给出了用ＡｕｔｏＣＡＤ的ＡｕｔｏＬＩＳＰ语言写所的程序模块，用该程序模块可以实现由服装的几个基本尺寸转换成衣片图并用绘图机或打印机输出衣片图，实现衣片的计算机辅助设计。     

袖子结构与舒适性关系的研究

本文主要研究袖子结构与人体舒适性的关系．经研究表明，要使得袖子美观舒适，必须正确确定衣片的肩线，袖子的装袖顶点以及吃势，并要使得合体袖具有方向性。而在袖宽、肋宽、背宽及袖下尺寸等方面作适当的调整，可使得袖子有良好的活动机能性。     

An interactive co-evolutionary CAD system for garment pattern design

Traditional CAD (Computer-Aided Design) methods in garment pattern design (GPD) fail to utilize the knowledge of experts for inexperienced designers. Moreover, the interactive and co-evolutionary features are not supported. We propose an interactive co-evolutionary CAD system for GPD (ICE-GCAD). The functionality model, modular architecture and data flow of the system are proposed. Then, the interactive co-evolutionary system whose core module is an immune-inspired co-evolutionary algorithm is studied. Finally, the flow of co-design in the system is proposed. As a case demonstration, we study a design sample of a leisure shirt. The experimental studies show that our approach has promising performance and appealing effects. We believe ICE-GCAD is applicable to support the collaboration among garment designers and experts.
