Study And Optimization Of Delivery Operation In LY Company

With the rapid change of external Politics,Economy,Society and Technology,the pressure of enterprise competition is increasing.especially in the traditional labor-intensive manufacturing plants in the pearl river delta region,the increase of labor cost makes the manufacturing cost account for a higher and higher proportion of the total cost.As the manager of the manufacturing factory,they should return to the operation site,improve the operation efficiency and reduce the production cost through continuous improvement on the shop floor,so that the enterprise can survive in the fierce competition.Lean logistics is the application of lean concept in logistics,which is a means and method to eliminate waste in logistics operations and improve operation efficiency and quality effectiveness.This paper,from the standpoint of W manufacturing factory,takes the initiative to optimize the supply chain with its mechanical material suppliers,and focuses on the analysis of the"pain spot"problem in the delivery process of material supplier LY company,that is,the phenomenon that the supplier delivery vehicle cannot timely unload the goods and often"waiting".Through the observation of LY company’s"三现"on the delivery operation site,we found that:(1)in the operation site of YD logistics park,it takes about 2hours for a truck to enter the park and finish loading;(2)delivery to W3 factory it takes about4 hours from the time of arrival to the time of delivery.In theory,only 1 truck can meet the transportation demand,and in practice,5 trucks are used,resulting in the waste of logistics transportation cost.Through data collection,the author analyzes the reasons for the long waiting time of delivery vehicles,and use the characteristic factor diagram to determine that "the actual demand of production line is inconsistent with the purchase plan" is the real reason for the waiting of trucks.A JIT(pull system)material distribution method is developed,that is,the delivery of the required products at the required time according to the required quantity.According to the actual situation on site,the formula is used to calculate the safety inventory,the quantity of order points and the order quantity.The electronic kanban system and the call material progress tracking kanban were introduced to realize information transparency and cross-organizational system collaboration in the supply chain.The SIG external inspection mode was introduced to cancel the SQM inspection to improve the operation efficiency.Set up the material preparation area to prepare materials in advance to reduce the waiting time of freight car and the time of handover and inventory of materials.After the implementation of the measures,the waiting time of trucks was reduced to "zero" and the target for improvement was achieved.The whole improvement project has achieved very good tangible results(economic benefits)and intangible results,eliminate the waste in the process of logistics distribution,improve operation efficiency,and save logistics costs.It provides a good reference for other factories of the group and an improved sample for the optimization of supply chain logistics.
