Embodiment Construction

[0037] A JIT-VMI-based supplier direct supply line-side material distribution method, such as figure 1 shown, including the following steps:

[0038] (1) Obtain the production tact of the supplier's material, the production tact of the manufacturer's assembly line, the cycle time of the production plan, the time for the supplier to deliver the material to the VMI warehouse, the loading and unloading time of the material on the line, the safety stock coefficient of the material in the VMI warehouse, and the cycle time of a production plan Inside, the production volume of the corresponding product, the quantity of materials required to produce a single product, the supply ratio of the supplier to supply the corresponding materials, the VMI material storage cost per unit quantity and unit time, the fixed cost coefficient of one-time material delivery by VMI warehouse, and the unit distance cost coefficient of VMI warehouse delivery , the distance between the VMI warehouse and the...

Abstract

The present invention relates to a JIT-VMI-based supplier direct supply line-side material distribution method. Firstly, relevant data parameters are obtained, and then the minimum material distribution total cost model is established, that is, the supplier direct-supply line-side material distribution dynamics based on JIT-VMI The period optimization model, and finally the minimum total material distribution cost model is processed to obtain the optimal distribution batch size and optimal distribution frequency under the minimum total material distribution cost. It is possible to determine the optimal material distribution period and VMI inventory standard that is coordinated with the manufacturer's production plan sequence and adapts to dynamic needs. The punctuality of material distribution improves customer production efficiency, meets individual customer needs, and minimizes the total cost of material distribution, while simultaneously reducing the inventory of suppliers and manufacturers.

Description

technical field [0001] The invention relates to a JIT-VMI-based material distribution method for direct supply from suppliers. Background technique [0002] Mixed-flow assembly production is to meet the individual needs of customers. Products with similar assembly processes but different models are assembled on one production line to achieve low-cost, high-quality and high-efficiency flexible production methods. Mixed-flow assembly production can effectively improve production efficiency and reduce costs, but at the same time increases the difficulty of punctual material distribution. Material distribution is a logistics activity in which materials are delivered to the process or station in a timely manner according to the demand according to the product BOM and the material consumption of the process or station in combination with the production beat. It is the core element in the production logistics system. Among them, the dynamic material distribution period standard co...
