Research On Information Technology In Apparel Process For Manufacturing

Deepens gradually along with the global economic integration advancement, China clothing enterprise demand to promote the information based technology level as soon as possible, the informationization that the clothing produces mainly includes: technology about design information, technology about structural design , technology about production technological design. As CAD technology mature today in the clothing, the technological design in the clothing manufacture system has become to urgently need Researching and Application day by day. As a branch research of "The Application of Information Technology in Clothing Produce " which is a key topic sponsored by Shanghai Municipal Education Commission, This research will help enterprises to accommodate the trend "Many kinds, Small batch, High quality, quickly delivery".This article first studied has constructed the digitized clothing production craft system overhead construction, then key research digitization clothing production craft system 2 aspects technology: The clothing production craft information encoding designs and realizes, based on the genetic algorithms clothing production assembly line arrangement optimization.Has studied the digitized clothing production craft main content and the model, the model tradition profession CAPP system, in the analysis digitization clothing production craft system demand foundation has constructed based on technical digitization clothing craft information technology platform the and so on the database, construction of data overall overhead construction, and divides into the clothing craft coding system, the craft input system, the craft decision-making and the technological document production system, the technological document output system, the distributed database management system and so on 5 big modules, and further has discussed 5 big modules basic functions.Carries on the clothing production craft the research, first must fully grasp the clothing design the structure and the craft characteristic. The craft information description is the CAPP system work foundation , After of a large amount of practising in clothing factories, Collecting the materials,studying and research, the design of code rule and scheme is carried out. With consulting the classification code of other major, in the analysis clothing craft information standard classification code request and in the reasonable code scheme foundation, involves to the clothing craft information process in to the information carries on the code definition, each kind of clothing craft information by digital or letter form classification, performance, memory. Unifies the certain coding rule, establishes the relation for each kind of craftinformation between, carries on the graph information encoding, the technological document code, the clothing GT classification code and the model code structural design, does not cause the classification to code into the isolation the individual, but is can comprehensively describe clothing craft some essential factor.The method of assembly line arrangement in clothing profession production is old at present, The ptimization of clothing production assembly line arrangement can enhance the clothing enterprise competitive, the article solves the problem of optimizing the arrangement of working procedures on clothing assembly line with Self-adaptive. This thesis chooses Roulette and elitist model as selection, chooses multi-point crossover as well as choose inversion as mutation. Moreover, it add starttime and overtime into the working procedure table, so as to calculate fitnesses of chromosomes easier. Then, design program, simulate the algorithm with this program in order to verify that GA can be used in optimizing the arrangement of clothing assembly line.This article carries on the digitized clothing production craft information technology research, has constructed the digitized clothing production craft system overall frame, designed set of code schemes, has obtained one effective assembly line optimization method, was advantageous in the digitized clothing engineering research further advancement.
