Sammanfattning
In recent years, the constant improvements in production planning has become increasingly
important for manufacturing enterprises seeking to maximize their market
value in a volatile industrial environment. This thesis is entitled towards providing
an optimized production planning model. Mark Bric is a manufacturer of size
marker hangers which are mainly used in the clothing industry. Size hangers are
of different varieties which differ in size and color. When there are many varieties
of products to be produced in manufacturing line it requires time for change-overs
between each variant change. The aim of this thesis is to develop the resources
needed for Mark Bric to become more efficient in their sequencing of these variation.
This thesis illustrates how an investment decision was analyzed by constructing an
objective function, constraints, variables, and solving it using a mixed integer function
created in Python. The authors of this thesis has researched the optimal number
of machines needed to be procured to satisfy the future demand. Throughout this
thesis 4 different numbers of machines (4-5-6-7 machines) are going to be analyzed
over 4 different production demands, this will create 16 different scenarios of data
which will be analyzed to make a the investment decision.
The comparison shows that using 6 machines allows for an advantage in terms of
total machine run-time when compared to other scenarios. The majority of scenarios
shows that there is a decline of around 50% compared to 4 machines and 68%
compared to 5 machines. also, the overall change-over time during 6 machines is
reduced. Therefore, it demonstrates that production alignment is well-organized
while using 6 machines. Hence, purchasing 6 machines will be beneficial because it
would allow Mark Bric to achieve a more efficient output.
