The Research On Principle Of Product Platform Evolution And Inplementation Method

Along with market competition intensifying,the market is saturated and enterprises gain profit from products to reduce.Under the guidance of this competition of idea,enterprises often seek a best interest between "diversity" and "cost".At the same time,market supply and demand gradually shift to the direction of the customer.Enterprises continuously improve their products to diversification,but the diversification of products lead to the cost increasing.Product platform was born between the diversification and decreasing the cost of product,it can effectively coordinate the cost of enterprise and requirements of customer.In addition,in order to guarantee the market share,enterprises need to be done in time that process to the existing product platform evolution.The current research of product platform evolution is confined to method and rule,which is not in-depth analysis in the principle of product platform evolution and evaluating the scheme of platform evaluation has certain subjective factors.The following is the main research content of this article:1.This article based on the existing product platform evolution rules and methods,combining the entropy and dissipative structure theory,puting forward by the entropy change generate dissipative structure of product platform evolution.And from the nature,reasons and motivation of formation,elaborating the product platform evolution principle in detail and establishing the dissipative structure model of product platform evolution.2.In the process of product platform evolution has selected platform scheme decision,the existing methods are basically based on subjective evaluation,which describe differences between different people.Information entropy in this paper as a kind of the negative entropy which introduced from the outside world,and this paper base on information entropy established comprehensive evaluation model of product platform.This method from the platform itself exclude man-made interference and can objectively evaluate the evolution of platform scheme,making the right decisions.3.In the actual project,the fan of combine-harvester can not produce enough airflow in the operation,and the shell of fan will collide with the ground.Using the above processes and methods complete the evolution of the harvester fan platform.
