Abstract
The garment industry in Vietnam is one of the country’s strongest
industries in the world. However, the production process still encounters
problems regarding scheduling that does not equate to an optimal process. The
paper introduces a production scheduling solution that resolves the potential
delays and lateness that hinders the production process using integer programming
and order allocation with a make-to-order manufacturing viewpoint. A
number of constraints were considered in the model and is applied to a real
case study of a factory in order to viewhowthe tardiness and latenesswould be
affected which resulted in optimizing the scheduling time better. Specifically,
the constraints considered were order assignments, production time, and
tardiness with an objective function which is to minimize the total cost of
delay. The results of the study precisely the overall cost of delay of the orders
given to the plant and successfully propose a suitable production schedule that
utilizes the most of the plant given. The study has shown promising results
that would assist plant and production managers in determining an algorithm
that they can apply for their production process.
