Sequencing policy for a CONWIP production system
… of a constant Work-in-Progress (CONWIP) production system through the sequencing of its backlog list is investigated. The performance measures considered are throughput, optimum WIP level (m*), and flow time. Analysis of the effects of sequence dependent bottlenecks on system performance …

Simulation study of a kanban-controlled production system
… (JIT) has become one of the most popular production control philosophies in the last three decades. JIT did not find acceptance in the American companies until after the oil crisis. To be more flexible and to adapt quickly to changes in the market, many American companies took to the …

Inventory control through a CONWIP pull production system
Production systems such as the CONWIP (constant work-in-process) pull production system have been widely studied by researchers to date. The CONWIP pull production system is an alternative to pure push and pure pull systems that lowers and controls inventory levels and reduces production lead time. …

Trace element contaminants in the Kuwait water production system
Fresh water in Kuwait is produced by non- conventional methods. About 95% of this water comes from desalinated seawater using multi-stage flash distillation technique and the remainder comes from underground brackish water. The blended water containes organic, inorganic and trace metal impurities …

Making a high-mix make-to-order production system lean
A high-mix, make-to-order production system can become inefficient when non-value added operations consume too much time, space or labour. To address these issues, cell re-layout is conducted and a CONWIP system is proposed. The cell re-layout started with data collection on current layout, product …

Asynchronous stochastic learning curve effects in a large scale production system
Large scale production systems contain dynamically unequal distributing lead times and improvement rates. This has made it very problematic to statistically predict the ability of global partners to meet common deadlines simultaneously This system behavior can be attributed to the effects of …

Dynamic Lot Sizing and Scheduling in a Multi-Item Production System
… in a single level (or single operation) production system. This research deviates from previous research in this area in that it does not have the kind of assumptions regarding the real world production system that normally were made to reduce the complexity of the problem. Specifically, …
