In northeast China, logging has three stages; timber
harvest, transportation and the operations inside a timber
yard. The timber yard is an intermediate transhipment point between truck transport and rail transport to manufacturing centers. The transhipment capacity of the timber yard is often the limiting acitivity in the logging chain....
Poor material utilization is inherent to conventional manufacturing processes, leading to high material waste and machining times. Additive manufacturing processes attempt to solve this issue by allowing production of near-net shapes, but the processes may be too expensive or infeasible. By leveraging both processes in a single part, the waste...
In this dissertation, a two stage flexible flow shop scheduling problem is studied, where in stage 1, there are identical batch processors (burnout ovens) and in stage 2, there are identical discrete processors (furnaces). Batch processors perform a pre-heating process on a batch of jobs at a time and discrete...
This research considers a combinatorial optimization scheduling problem in the assembly of printed circuit boards (PCBs) in electronic manufacturing. For the first time in this research, the preparation process, which is typically called kitting operation, is paid attention to and is performed along with the assembly operation, described in this...
A solution to the problems of computer scheduling of students
based on course requests rather than section requests is discussed.
The solution involves keeping all course data in core during the
scheduling process to enable the scheduling program to run as fast as
possible and using a scheduling algorithm which...
In this research, a bi-criteria group scheduling problem is investigated in hybrid flow shop (HFS) environments, where the parallel machines in each stage are unrelated, meaning not identical. The objective of the problem is to minimize a linear combination of the total weighted completion times as a means of complying...
Plywood production scheduling for years has been
considered, more or less, a sacred activity in which only
a select group of individuals with the experience and
knowledge could take part. With the advancements in
computer technology and related fields, the plywood
industry is in a position where more people can...
Expert systems have been suggested as a solution
for difficult problems, including FMS scheduling. As
one of the aspects of artificial intelligence (AI), expert
systems have achieved considerable success in recent
years in medical science, chemistry, and engineering.
However, building an expert system is a difficult
task, the most crucial...
