Abstract
The rigid interlinking of assembly stations in assembly lines is increasingly leading to cycle time losses and inefficiencies. In this context, matrix-structured assembly systems have emerged as an alternative, cycle time-independent form of assembly organization. In matrix-structured assembly systems, the assembly stations are decoupled from each other and arranged two-dimensionally, similar to the squares of a chessboard. The assembly activities to be carried out and the assembly stations to be passed through are determined by a reactive assembly control system depending on individual order characteristics and station availability. Unlike in assembly lines, occupied, inactive or unnecessary assembly stations can be skipped. As a result, matrix-structured assembly systems promise a reduction in cycle time losses and inefficiencies compared to assembly lines. At the same time, however, the number of degrees of freedom to be taken into account in assembly control increases and with it the complexity. This also applies to order release, which is an integral part of assembly control. Until now, approaches to order release in matrix-structured assembly systems have not been based on a detailed comparison of order-specific capacity requirements and activity-related processing offers. However, this is crucial for the economic evaluation and efficient operation of matrix-structured assembly systems. The overall objective of this dissertation is therefore the development of a methodology for capacity-oriented order release in matrix-structured assembly systems. The methodology is modeled as part of an agent system for decentralized assembly control in an evaluation environment, whereby the interdependencies within the assembly control are realistically modeled. The simulation-based evaluation of the methodology is carried out using the example of battery assembly, examining and proving the general functionality of the methodology and its added value, taking into account relevant productivity indicators.
