Implementing theory of constraints in a job shop environment
… are described. An implementation of the drum-buffer-rope material control process is described in this thesis. To enable the implementation, a data management system was developed. The system utilizes the concept of critical ratio scheduling priority, a time buffer to protect bottlenecks …

Synchronous manufacturing : implementing "pull" production in a job shop environment
… Shop. This thesis focuses on the design of a Drum-Buffer-Rope implementation of the Theory of Constraints in a high variability, high volume steel fabrication shop. Additionally, it describes how this method was selected over alternative pull systems. Finally, a case study of implementation …

Improving Manufacturing Systems Using Integrated Discrete Event Simulation and Evolutionary Algorithms
… here has investigated the job sequence and buffer management problem in high variety/low volume manufacturing environment, where lead time and total inventory holding cost are used as operational performance measures. The research here has introduced a novel approach through integration of …

Equipment protective capacity optimization using discrete event simulation
… WIP policy alternatives (CONWIP limits vs. drum-buffer-rope starts policies). Reduction of CONWIP limits from 4 days to 3 days appeared robust and generated a 20% decrease in TPT. Equipment protective capacity was optimized. The results indicate that the current gap policy of 10/15/20 is …

Interpreting and applying demand driven MRP: a case study
… – DDMRP is shown to embody the concepts of buffer aggregation and buffer management within the context of dependent demand planning, effectively integrating MRP and TOC. The underlying production planning and control issues of the company were found to be consistent with the literature …
