ABSTRACT
Because the purchase and the supply of electronics manufacturing industry is so inbalance, it
brings the restriction and obstacle to continuous development of the electronics
manufacturing industry. Therefor, the writer of this article believe, the smooth connection
between the supplier and purchaser can be realized in JIT procedure. This paper argument
this procedure from supplier selection and the task allocation based on JIT platform and then
analyzing the efficiency of purchase and cost of stock by this method. Supplier selection and
the task allocation based on JIT purchase is the key studying point and also one innovative
viewpoint for JIT purchasing. This paper draw the following conclusions: firstly, the
application of supplier selection and the task allocation based on JIT purchase for DT corp. is
effective for improving the JIT of purchasing. Secondly, batch supply according to the
demand on order (Kanban) through strategic cooperation with supplier decreased the cash
flow used for purchasing by the means of Order Point Method or Batch Purchase. Thirdly,
defend measure can be made to improve JIT purchase in advance and guarantee its
effectiveness through further forecasting of efficiency of purchase. Fourthly, due to the
selective distribution of supply to suppliers, material stock and safety stock were transferred
from manufacturer to supplier and eliminating past stock reduce even avoid the cost of stock
possess, stock acquire and out of stock through reasonable distribution. The study meet some
problem at three aspects. The first one is the manufacturing enterprises acting JIT whether
have feasibility, regulatory and rationality; the second one is how to choose the punctual
suppliers and which is the strategic alliance take; the third one is how the manufacturing
company to implement allocation in order to guarantee the agility and security of the supply
chain. To face these problems, the writer groped out a set of method by the practice in
purchasing business. The writer use the Cross Mark and a series of calculate formulae to
choice the suitable supplier, and implement task allocation by linear programming method.
Another thing is the writer taking advantage of the smoothly technology carries on the result
to analyze and predict the development curve. The subject gets a good result in practical
application by the design and analyze, so, it is proved that through the scientific
technological methods can promote the supply and purchase to be just in time and
cooperation, and the product quality will be better and better. Then, according to inside
contact of products the writer sets up model used for amount of spare parts and finance,
besides, he puts forward a method to deal with the unpredictable stock phenomenon in the
production. To corporation, taking advantage of predict and practice brings something to
itself, that is, shrinking the stock gradually, improving the quality of goods, long-term solid
supply price of goods, reducing the costs, increasing efficiency and really realizing the
