¡¡¡¡A. Supply conveyor chain information transmission based oninternet of thingsAccording to the above analysis, the problems insupply chain information transmission are mainly due tothe traditional information transmission chain model. As a newtechnology, internet of things breaks the traditionalvertical information transmission model. From thedownstream to the upstream, internet of things makes itpossible for the supply chain members to get the real-timeproduct information. So it can effectively solve theproblems of information transmission lags. Figure 3 showsthe network structure of internet of things whentransmitting information in supply chain.
¡¡¡¡B. The problems of information transmission in supplychain .In a buyer¡¯s market environment, for manufacturers,leaving downstream information feedback, they can¡¯t doreasonable decision-makings such as the amount ofproducts for every batch. And for distributors, they alsoneed real-time information to support theirdecision-makings, such as the decision-making onreasonable inventory. However, in traditional supply chainmanagement model, the lack of information sharing haslead to the "bullwhip effect". Supply chain information transmission lags are shown as follows.
¡¡¡¡£¨1£© Demand ForecastIn order to arrange production progress, plan outputand control inventory more reasonably, supply chain enterprises need to forecast product demand. However,traditional information sharing method has led to seriousinformation asymmetry. Therefore, in supply chain coupling,upstream enterprises can¡¯t get real demand information. Insome cases, the change of the retailers¡¯ order can¡¯trepresent the same change of the customers¡¯ demand. Onlywhen mastering the final customers¡¯ real demandinformation can the manufactures forecast demandaccurately.
¡¡¡¡£¨2£© Price fluctuationsPrice fluctuations will lead to purchase in advance.
¡¡¡¡Manufactures and distributors usually promote customersto increase purchase in advance through some promotionalmethods, such as price discount and quantity discount.
¡¡¡¡This increased purchase doesn¡¯t represent the real currentdemand. So purchase is not in line with consumption.
¡¡¡¡Finally, price fluctuation will result in "bullwhip effect".
¡¡¡¡£¨3£© Limited supply and short-term gameWhen products are in short supply, suppliers usuallybalance supply and demand through limited supply according to orders from buyers. However, it will inevitably cause buyers¡¯ excessive reaction because of their short-term game to this limited supply. Once thesituation is alleviated, orders will decrease suddenly.
¡¡¡¡Therefore, the result will be that it is impossible for suppliers to distinguish the real increased demand and the inflated phenomenon because of short-term game.
