Comparation of Schedulling Methods: Campbell Dudek Smith, Palmer and Dannenbring to Minimize Makespan

Abstract

Delays in completing one of production cycle will affect the entire flow of the next production process. DI is a manufacturing company that manufacture aircraft. In 2017 there was a delay in manufacturing processes of A380 aircraft wings, especially in machining parts, which resulted in delays shipping to assembly parts. This delays affected time delivery to customers. So that, scheduling plan was needed in this company. This paper proposes comparation of three scheduling methods, which are Campbell Dudek Smith, Palmer and Dannenbring with the aim of minimizing makespan. Result of this study describes that the best method for minimizing makespan is Campbell Dudek Smith method, with a scheduling sequence starting from job 13-6-5-3-10-4-9-1-7-8-18-11-14-19-17-2- 12-12-15-16, and the makespan value of 46.03 hours taken in constructing both.
