Research On Construction Enterpirese Material By Lean Management

Materials management is a very important enterprises management forconstruction enterprises. Because China experienced a long planned economy period,materials management of construction enterprises is an old concept and it's in lowlevel. Lean thinking comes from Japan's Toyota Motor Corporation's production,which is an advanced management. Its essence is the elimination of all waste and thecreation of wealth. This article starts from the concept of lean thinking ,combineswith the special materials management way of construction enterprises, discusseshow the construction enterprises achieve supplies lean management in their dailywork, so as to achieve the goal of lower material cost and effective management ofconstruction enterprises.Lean supplier management is an important part of lean materials management inconstruction enterprises. Having a stable, reliable and long-term cooperation supplierteam is the premise of construction materials'durability, full amount and stablesupply, as well as the key of reducing material inventory. At this stage, constructionenterprises have their own qualified supplier library. Comprehensive scientificevaluation system is the scale of measuring lean suppliers, realizing the dynamicsupervision of the qualified suppliers. Based on the disadvantages of existing supplierevaluation indicators of construction enterprises, through communication with theenterprises'workers, lean supplier evaluation system is proposed. Furthermore, theauthor applies the vague comprehensive judging method, and implements theassessment result with scientific data support.Inventory management is the key point to control the materials cost. Leanthinking emphasizes the agility and punctuality of material supply, which is the wayto achieve "zero inventory". Agility is the rapid response to the change of demand forgoods, which means on the basis of existing construction enterprises'monthlymaterial requirements plan, the weekly report of every month's material demand canbe achieved. When demand changes, it will be reported in time, then materialsmanagement departments will update the plan and implement response measures. Theentire plan needs constant adjustments, and the rolling material requirement planningwill be formed. JIT procurement will be used in construction enterprises to reduce material inventory.Information is the bridge of entire material management. A large amount ofcomplicated information is involved in material management of constructionenterprises, and in order to achieve a timely and accurate information transmission,an electronic information management must be needed. In the actual investigation, thebusiness process of construction enterprises materials management is well understood,lean thinking is used to standard business processes, functional modules ofconstruction enterprises materials management is also planed. Material managementinformation system can achieve the sharing of information resources and reduce theloss and delay of information transmission, which is the basis platform for realizinglean material management.Through the implementation of lean management for suppliers, inventory andinformation, lean management of construction enterprises is well interpreted, and ithelps to improve the material management and enterprises management.
