Abstract
AbstractA Just-in-Time (JIT) Material Handling System attempts to manufacture products from start to finish by rearranging the factory floor layout away from batch production toward a product layout using flow lines. One of the most accepted JIT production methods used in this work is known as the Kanban system. Kanbans are used to operate a pull system of material control that links all supplying operations to a final assembly line. The ultimate goal of this system is the conversion of raw materials at the Juhel Oral Drug Process plant into finished products with lead time equal to processing time. The flows in the manufacturing model include: the flow of materials, the flow of information, and the flow of cost. These flows create the value streams. Components of the value stream can be value-add or waste, depending on the operating conditions. The simulation model developed in this research work is based on the single-card pull system developed at the Drug Process Plant. This model consists of three blo...
Highlights
According to Doll and Vondermbse (2011), Just-in-Time (JIT) attempts to manufacture products from start to finish, the first step in applying JIT production, is to reorganize the factory floor layout away from batch production toward a product layout using flow lines
The Just-In-Time (JIT) system implemented at the Drug Process Plant provides many benefits, those associated with inventory reduction at the end buffer, shorter customer lead time, better visual control and better worker motivation
For the reason that this implementation was only a pilot project and it was applied to only one item, problems arose in the implementation that may not completely reflect the real problems encountered in the implementation for multiple items. Some issues such as setup time reduction, process variability reduction and product mix that are essential for successful JIT implementation did not become crucial issues in this research
Summary
According to Doll and Vondermbse (2011), Just-in-Time (JIT) attempts to manufacture products from start to finish, the first step in applying JIT production, is to reorganize the factory floor layout away from batch production toward a product layout using flow lines. Each flow line will normally be U-shaped. This layout allows workers to help other workers if any trouble occurs in the production line and enhance access to more than one machine. Since parts are produced based on demand, there is a constant flow of components rather than batches of work-inprogress (WIP). Doing the job right the first time is one of the main emphases of JIT production (Doll & Vondermbse, 2011)
