“…Therefore, the objective is to maximize the composite desirability value (𝐷), as shown in Equation (3), where the throughput response meets the target demand and the remaining response values are maximized. The 𝐷 ranges from 0 to 1, and the closer to 1, the better the resource allocation solution is.…”

“…Especially regarding operators and workstations, there are only more than a dozen operators in the assembly line, but there are nearly 100 workstations overall. Its production mode is neither a traditional assembly flow line [2] nor a pulsating line [3], where the products flow through the fixed stations with regular operators at each station. The operator resource of the assembly line is made up of a certain number of master and auxiliary operators, who work together to complete the assembly tasks of a workstation.…”

Resource-constrained product general assembly lines with complex processes face significant challenges in delivering orders on time. Accurate and efficient resources allocation of assembly lines remain a critical factor for punctual order delivery, full use of resources and associated customer satisfaction in complex production systems. In order to quickly solve the order-based dynamic resource allocation problem, in this paper a metamodel-based, multi-response optimization method is proposed for a complex product assembly line, which has the characteristics of order-based production, long working time of processes, multiple work area re-entry and restricted operator quantity. Considering the complexity of the assembly line and the uncertainty of orders, the correlation between system performance indicators and resource parameters is investigated. Multiple metamodels are constructed by the Response Surface Methodology to predict and optimize the system performance. The adequacy of the constructed metamodels is verified and validated based on the bootstrap resampling method. Under the condition of ensuring the throughput demand of the assembly line, the desirability function is applied to simultaneously optimize the multi-response, and the resource allocation solution is generated. The method in this paper can be used to rapidly adjust the resource configuration of the assembly line when considering the order changes.

“…Shrink-fitting assembly has the advantages of causing less damage to the connection interface, easy operation, etc., and it is applied to the assembly process of aero-engine rotor spigot interference connection structures [1,2]. Assembly, as the final step in the engine manufacturing chain, directly influences the initial state of geometric and stiffness characteristics of aero-engines [3], and the quality of shrink-fitting assembly processes directly affects the final assembly performance of the rotor [4,5].…”

The interference fit connection structure is widely employed in various industries. Different from the conventional connection structure, the aero-engine rotor connection has a spigot-bolt structure. The quality of the shrink-fitting assembly process directly affects the final assembly performance of the rotor. The complexity of the connection structure and the time-varying thermal deformation bring great challenges in analyzing the formation patterns of connection performance. However, existing methods of interference connection analysis are mainly used in the wide range of interference connection structures, which makes them difficult to apply in low height interference connection for aero-engine rotors. This paper introduces a thermomechanical interference fit pressure model. First, a theoretical model for interference fit pressure considering temperature-variable loads is established to obtain the time-varying pressure during the assembly process. Second, a finite element model is established to explore the influence of interference and temperature loads on the spigot pressure and the mounting edge deformation. Finally, the experiments validate the accuracy of both the theoretical model and the finite element analysis. The results indicate that during the shrink-fitting assembly process, the interference fit pressure exhibits a nonlinear evolution trend, and the warping deformation of the mounting edge is a result of the combined influence of temperature and interference fit pressure. The law found in this paper has an application prospect in the process parameter setting of shrink-fitting assembly for special structures.
