Embodiment 1

[0049] This embodiment provides a method for material distribution in a mixed-flow assembly line based on a static semi-complete strategy, including the following steps:

[0050] S1: Build the physical layer based on the static semi-complete strategy. The physical layer includes the bin preparation area, workstations and AGVs with mixed loads. The bin preparation area stores multiple bins, and the bins are used to store materials; the static semi-complete strategy is specific To: sort and assemble materials and store them in corresponding material boxes. When it is necessary to distribute materials to stations, the AGV with mixed load takes out several material boxes from the material box preparation area, and traverses the work required for refilling. AGV (Automated Guided Vehicle) refers to a transport vehicle equipped with automatic navigation devices such as electromagnetic or optical, capable of driving along a prescribed navigation path, with safety protection and various...

Abstract

The invention relates to a mixed flow assembly line material distribution method and system based on a static half-set strategy, and the system comprises: a sensing layer which obtains the remaining line side stock of each station and the state and position of a mixed load AGV in real time through a sensor; the conversion layer that is used for converting the data acquired by the sensing layer into useful information, determining whether a station has a replenishment demand or not, and summarizing material demands; the network layer that is connected with other layers to realize data exchange; the cognitive layer that determines an optimal material distribution scheduling strategy through data analysis according to the target function; and the control layer that determines a control strategy according to the cognition result of the cognition layer. Compared with the prior art, the invention considers the real-time inventory of each station, the state and position information of the AGV and the like, and has the advantages of effectively reducing the inventory level of the line side, improving the material distribution efficiency, reducing the operation cost and the like.

Description

technical field [0001] The invention relates to the technical field of material distribution, in particular to a material distribution method and system for a mixed-flow assembly line based on a static semi-complete strategy. Background technique [0002] After years of industrial expansion, the automobile industry has transitioned from a period of rapid growth to a period of stability. In such a fierce market competition, automobile manufacturing enterprises are faced with challenges such as diversification of consumer demand, environmental protection, and energy pressure. Various pressures force automobile manufacturing enterprises to improve their management level as much as possible and reduce operating costs. In addition, automobile companies also need to be able to provide diversified products and on-time delivery to improve their competitiveness. The production mode of automobile enterprises has changed from mass production in the past to mass customization today. ...
