Embodiment Construction

[0037] refer to Figure 1-4 . The specific steps of the calculation method for the production capacity of aircraft assembly line personnel in the present invention are as follows.

[0038] This example is to solve the personnel production capacity of the rear fuselage assembly line of a certain type of aircraft. The assembly line is mainly composed of 5 assembly stations and a total of 86 processes. people.

[0039] (a) According to the structural characteristics of the rear fuselage product group components and the process characteristics of the assembly process, the assembly operation is decomposed into the bottom assembly operation elements. After statistical analysis, the types of assembly operation elements are divided according to the types of processes k=1,2,...,N ij , and concluded that the main processes of rear fuselage assembly operations include: assembly preparation, pre-positioning / positioning of parts, drilling, riveting, cleaning and sealing, testing and remov...

Abstract

The invention discloses a method for calculating production capability of airplane assembly line workers. The method is used for solving the technical problem that an existing multidimensional layering production capability accounting method is low in precision. The technical scheme is that the method comprises the steps of first decomposing the assembly process to assembly work elements, calculating theoretical working hours consumed by each assembly unit in a system according to decomposing results, respectively considering three worker production capability influencing leading factors which are assembly accuracy class, learning effect and assembling strength with effectively working hours of workers as the standard, quantitatively correcting the theoretical working hours, finally solving other productivity key parameters through the effectively working hours of workers in each process, and calculating the production capability of a whole assembly line in unit time. With an assembling line for a rear fuselage of an airplane of some model as an example, according to tests, compared with a method for estimation of working hours by experience in the background art, the method improves worker effectively working hours solving precision by 15.4% and improves annual output solving precision by 8%.

Description

technical field [0001] The invention relates to a method for calculating the production capacity of personnel, in particular to a method for calculating the production capacity of personnel in an aircraft assembly line. Background technique [0002] The so-called personnel production capacity usually refers to the physical and psychological characteristics of the operator to complete a certain operation, which is comprehensively reflected in the hidden internal potential, which can be directly reflected in the time spent by the operator to produce a unit of product. For the assembly line of complex products such as aircraft, accurately solving and predicting the production capacity of personnel under the premise of given layout and organizational conditions is not only beneficial to assist on-site management and control personnel to quickly locate "bottleneck" stations and production constraints, and improve production planning. Execution; also helps to evaluate performance ...
