Scheduling manufacturing systems with work-in-process inventory control: single-part-type systems

Fuzzy work-in-process inventory control of unreliable manufacturing systems

We consider single and multiple part type production lines and networks with ®nite bu€ers and unreliable machines. Three fuzzy control modules, namely, line, assembly, and disassembly controller, are developed. The objective is to keep the work-in-process (WIP) inventory and cycle time at low levels, along with high machine utilization and throughput. This is achieved by adjusting the processin...

Simulation Analysis of Work-In-Process Inventory Control for Discrete Manufacturing Systems

Under the modern discrete manufacturing mode, the multi-variety and small-batch production system satisfies the requirements of the diversified demands of consumers, rapid responses to market needs and high core competitive advantages. Especially, in this production system, tightly coupled cells are widely applied to improve production flexibility and precision and reduce manufacturing costs. H...

Reducing work-in-process inventory in certain classes of flexible manufacturing systems

In this paper, we establish that maintaining a balanced workload on each machine over time stochastically minimizes the work-in-process inventory in certain types of flexible manufacturing systems (FM%) with finite or infinite common input buffer storage and an ample buffer et each machine. The results obtained here complement those obtained by Stecke and Morin (1985), in which it is establishe...

Scheduling in manufacturing systems

A scalarization-based method for multiple part-type scheduling of two-machine robotic systems with non-destructive testing technologies

This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...
