Beschreibung

Initial Situation

Product design decisions significantly influence manufacturing costs, particularly in assembly operations. Characteristics such as the number of components, joining methods, geometric features, and assembly complexity determine the required assembly processes and associated effort. However, detailed process plans and production times are often unavailable during early product development. Therefore, methods are needed to estimate assembly costs directly from available product design information.

Objective

The objective of this work is to develop a method for estimating assembly costs based on product design characteristics. Existing approaches to Design for Assembly (DFA), assembly time estimation, and feature-based cost modeling will be investigated and compared. Based on these findings, a method will be developed to derive relevant assembly operations and estimate their execution times from structured product information. The estimated assembly times will be combined with predefined resource-specific cost rates to calculate assembly costs. The proposed approach will be implemented in a prototype and evaluated using exemplary product designs. The evaluation will focus on estimation accuracy, sensitivity to design changes, and applicability during early product development.

Voraussetzungen

Interest in product development, assembly planning, and manufacturing cost estimation. Basic knowledge of manufacturing engineering and good analytical skills are required. Python programming skills are advantageous. Independent and scientifically structured working skills are expected.
