Performance of a Serial-Batch Processor System with Incompatible Job Families under Simple Control Policies
A typical example of a batch processor is the diffusion furnace used in wafer fabrication facilities (otherwise known as wafer fabs). In diffusion, silicon wafers are placed inside the furnace, and dopant is flown through ...
Modeling and Analysis of Re-entrant Production Systems
This paper presents a model and analysis of a re-entrant production line with finite buffers and unreliable machines. Semiconductor device and liquid crystal display (LCD) fabrication processes are characterized as a ...
Setting Real Time WIP Levels in Production Lines
A new algorithm is developed for setting WIP level in production lines. It is a pull policy that determines when to authorize a job to be processed. Dynamic information in the system such as machine failures and repairs, ...
Modeling and Analysis of Manufacturing Systems with Multiple-Loop Structures
Kanban and Constant Work-In-Process (CONWIP) control methods are designed to impose tight controls over inventory, while providing a satisfactory production rate. This paper generalizes systems with kanban or CONWIP control ...
