Sammanfattning
Purpose - In today’s globalized marketplace, businesses of all kinds experience a
constant change in customer needs and demands. For a company to stay competitive,
it is essential to have flexible production systems, which allow for rapid production
changes and ensure that new products are effectively and quickly introduced into the
factory. Before a new product, or a change in product specifications, is introduced
into the production system, two main areas must be carefully evaluated, i.e., the
identification of the critical features of the product and the identification of suit able machines to perform the required machining operations. The main aim of the
project is the development of a model based on the evaluation of those two areas for
identifying the critical parameters that have a direct effect on resource allocation at
GKN Aerospace.
Methodology - A triangulation of methods was used. A literature review was con ducted to get an overview of the research area. Quantitative and qualitative data
were retrieved from GKN Aerospace and analyzed to comprehensively investigate
the area of study.
Findings - The products and machines of interest were assessed for identifying the
critical parameters that have a direct impact on resource allocation. These results
were then used to analyze the associations between product features and machine
capabilities to develop a model that can help in implementing effective resource al location strategies at GKN Aerospace. Specifically, two products and about forty
machines were used to test the model. Recommendations were also provided on how
to improve and make the implementation of the association model more effective and
responsive.
Limitations - The research was limited to only the machines capable of performing
certain cutting operations (turning, milling and drilling) and to only three products.
The project does not include any software development to automate the association
procedure between product features and machine capabilities. Moreover, due to the
inaccuracy of some data (which in some cases were generalized for the purpose of
running the model), the results of the association matrices may not be accurate.
Furthermore, due to time constraints and lack of data, the model could only be
tested for two of the three products studied.
