Research On Feeding Material Logic To Production Line Based On Time And Quantity Dimension And Design On Workshop Material Delivery Management System

Aiming at the situation of disorderly materials management,high inventory on the production line and low distribution efficiency in the manufacturing workshop,a logistics operation method combining time and quantity dimension was proposed to study the logic of feeding material from the point of materials flow balance and based on Lean Logistics and action analysis method.The method was used to reduce inventory on production line,eliminate waiting time,improve the production line balance and production efficiency finally.The main contents of the dissertation are as follows:(1)The theory of manufacturing production logistics was researched.The operation requirements of enterprise production logistics were analyzed from materials supply and material flow.The production logistics operation flow chart were designed to analyze key parameters,which put forward the requirements of systematic distribution in the workshop.(2)Taking a domestic engine manufacturing as an object to analyze workshop layout,material requirements,material distribution process,propose the logistics problems and improvement goal.The action analysis method was used to analyze factors that affected production line balance.Based on unitized materials packaging,workshop material distribution was studied from the time and quantity dimensions,which proposed the content of materials distribution.(3)The feasibility of production orders and the distribution main body were researched to set up production time scheduling model.Based on the inverted time method and the distribution main body,The model of time and sequence relationship was established.Combined with production time scheduling,time and the quantity dimension,the material delivery time interval model was designed to research the logic of distribution time zone and work plan split,which could provide instruction to the design of workshop distribution management system.(4)According to the logic of delivery time and quantity to design the function structure and data model of workshop distribution management system,which based on information flow to perform distribution process.The workshop distribution management system that used C#language was designed from data access layer,business logic layer,and interface display layer,which could guide the workshop logistics operation and feedback work information timely in the form of material flow,information flow,work flow,and time flow.
