Analysis on traditional manufacturing and marketing mode of steel business Procedure of traditional mode For iron and steel enterprises, ERP system mainly consists of the production planning and management (PP), materials management (MM), sales and distribution(SD), financial management (FI) and quality management (QM) and other function modules, MES includes operation planning, production scheduling, material tracking, equipment management, quality management, process management, inventory management etc[2].
Advanced planning system of ERP has demand planning, order management (including: matching stock ATP and available capacity promise CTP), the quality design, materials planning, capacity planning, limited capacity planning and other core functions.
It cannot achieve smooth connection of production planning and materials planning of each branch factories by relying on four advanced planning systems in the planning stage.
Level 4 coordinate isolated level3 systems and achieve effective connections of production planning and materials planning of each branch.

Introduction Along with the significant exaltation of science technique level, the social material wealth was consumedly stored.
Because product design, which is a compound process, is the fusion of science and technology, art, psychology and many other factors, if only in a purely logical reasoning, based on the achievement of product features to emphasize the evolution of design, users will inevitably ignore the pursuit of beauty and personality, can not in the vast design space to find the optimal solution.

In the distribution mode, it’s a heavy workload to maintain the servers of multiple nodes in the purpose of facing application software upgrade, database table structure maintenance and avoiding paralysis from virus infection or hardware failure, which requires more manpower and material resources
It can be believed that, with the development of science, the technology will be more intensive.
