Embodiment Construction

[0034] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0035] An embodiment of a sub-packaging production method of a multi-variety and small-batch mixed-flow assembly line:

[0036] In tractor mixed-flow assembly production, the optimization goal of sub-assembly production is to meet the needs of final assembly on time and quantity. Tractor sub-assembly production includes the assembly of key components such as engine, transmission system, braking system, cab, etc. The present invention is based on the manufacturing execution system MES (Manufacturing Execution Syetem), using BS (Bubble Sort) automatic sorting algorithm, through computer programming to design the automatic sorting heuristic algorithm (Final assembly-automatic sequencing heuristic algorithm, FA-ASHA) of mixed-flow assembly production to realize the lean and informatization of tractor mixed-flow assembly production planning and automat...

Abstract

The invention provides a multi-variety and small-batch mixed-flow assembly line sub-packaging production method and device. The invention first sets the production sequence of each type of product in the final assembly, and according to the production sequence of the final assembly production of each type of product, meets the requirements on time and quantity. Assembling needs of final assembly, establish sub-package production objective function; then according to the lead time T of each sub-package line j and the final assembly start time is T 0 , calculate the start time of packing as T sj =T 0 -T j ;Finally according to the starting time T of packing sj , lead time T of packaging j , General assembly sequence requirements and model configuration information, calculate the daily output of sub-assembly parts, so that the tractor sub-assembly production can be carried out in an orderly manner, ensuring that the punctual assembly requirements can be met, the production cycle is shortened, and the production efficiency of the final assembly is improved.

Description

technical field [0001] The invention belongs to the field of mixed-flow assembly production of tractors, and in particular relates to a sub-package production method and device of a multi-variety and small-batch mixed-flow assembly line. Background technique [0002] Tractor is a kind of non-road working machinery under complex working conditions. Tractor is a typical product of agricultural machinery equipment, and its advanced production technology is directly related to the international competitiveness of my country's agricultural machinery and even agricultural products. Tractor 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, usually including Parts sub-assembly and product assembly are two-stage production. Among them, the sub-assembly production of tractors i...
