Garment Sewing Hanging On Production Scheduling Technology

With the development of modern manufacture technology and computer technology, multi-cell technology of garment manufacture system was enrichment and perfect by and by too. Disquisition to garment suspending system scheduling technology was carried through in this thesis.The thesis introduced process design and plan of garment manufacture. Next, it presented the general situation of garment suspending produce line and production of company home and abroad. Moreover, based on investigation on Shanghai International Garment Equipment Exhibition in 2002, it showed that process design, man-hour ascertain and scheme about workstation quantitative of garment assembly line also depended on manpower to estimate plan and piece to together, and then reintroduce to suspending produce line even though suspending garment produce system. So, it was inaccessibility to suit efficiency to assembly line. Aimed at the actuality that garment suspending line technics instruction needed also handwork arrangement and then reimported computer to schedule, we studied scheduling technics of garment suspending line in this thesis. On the assumption that workstation was known, we started from working procedure table, educed pretreatment working procedure table based on original time and then obtained correlating information such as priority area, embranchment, embranchment point. We obtained optimum scheduling of garment suspending line using GA. Based on other industry ,target function was present:minSI= . It was using smoothness index to value capabilityand efficiency of suspending line.This thesis placed emphasis on process design and plan of garment manufacture. Through academic research and comprehensive investigation, combining actual manufacture of garment enterprises , garment sewing assembly line optimized scheduling system based on GA was empoldered. This system began from working procedure analyzed table. Initialize time was educed by actual workstation number. At last, pretreatment working procedure analyzed table was gained. It was a base about mostly data of this system. From pretreatment working procedure analyzed table we can find many data. For instance, embranchment working procedure, embranchment pointworking procedure, working procedure total, working procedure and correspond process time. Moreover, this thesis worked out priority area chart. It was based on successively sequence of process manufacture and principle to lessen number of one man working more machine to the best of our abilities. On the based of priority area, this question was solved using GA. This thesis used trousers that used in mostly literatures as actual example to carry through. Through comparing outcome in this thesis with outcome in other literature, it showed that the system in this thesis was preferable to solve the question. In addition, on the based on arrange outcome, this thesis processed dynamic simulation to run of garment suspending produce line.Aimed at NP characteristic of scheduling problem in garment suspending line in this thesis. Mathematics model was set up. We researched that could obtain optimized answer using GA. We settled computer aptitude scheduling system key technics of garment suspending line. It could handle practical production and could improve produce efficiency of garment suspending line. At the same time, it arranged working procedure with reason. Through priority area, we considered factor of equipment. Thus, it employed given mathematics model to be close to practicality even more. It settled foundation for garment manufacturing information.
