Decision models for single-period products with two ordering opportunities

Article Abstract:

An inventory decision model was investigated in which a single-period 'newsboy' type product can be ordered twice during a period. The model, which can be addressed through the use of computers and software, was proven to be more complex than the simple one-order-per-period newsboy problem. Resolution of the model enables operations managers to effectively handle situations related to production and ordering, such as when to undertake a second order.

Integrated decision modelling of supply chain efficiency

Article Abstract:

A study was conducted to analyze ways of improving the efficiency and effectiveness of supply chains. In line with this, four criteria were utilized. These were profit, leadtime performance, waste elimination, and delivery promptness. A model was then designed to analyze supply chain performance at two levels, namely, the chain level and the operations level. Results indicated that manufacturing strategies support sensitivity characteristics.

A study on production lines with discrete batch WIP inventory transfer

Article Abstract:

Asynchronous serial lines were analyzed in which WIP inventory is stored and transported in containers between stations. The WIP inventory transfer under consideration entails identification of container's quantity that will be alloted to every buffer location, the interstation distances and the container size. Containers to be transported are found to be capable of lessening the capacity utilization of the line.
