Kanban Based Scheduling in a Multistage and Multiproduct System
In the highly competitive manufacturing environment, many companies around the world are searching for ways to improve manufacturing performance. This is in response to changes in the manufacturing environment reflected by shortened product life cycles, diverse customer needs and the rapid progress of manufacturing technology. A JIT tool otherwise referred to as kanban based scheduling is then considered as a suitable management concept for Juhel Pharmaceutical Nigeria Ltd to address the challenges by minimising all the components, particularly on the shop floor. The JIT system is not just related to Kanban implementation but it comprises an all-inclusive approach for improving batch size reduction, setup time reduction, quality, production planning, and human resources management. Mechanisms and operating procedures are required to provide detailed step-by-step instructions for the implementation of a pull system. Basically, the Drug Process Plant operations are mainly characterised by single flow line production processes, periodical and multi-items orders. Based on the evaluation of the implementation of the new system, there are some factors that must be considered for further improvement including inventory reduction, improving visibility, batch size reduction and matching with other systems.
