Today’s World: Lean Manufacturing Environments and Cost Management

摘要

This paper will help to identify the interrelationship factor of cost management in lean production system. Standard overhead costs are sum up of expected direct labor & machine hours. In-fact major problem of cost is not direct labor or material, but the cost allocation. Before direct labor was a huge expense for the organizations, but now usually all works is done by robots and electronics instruments, so direct labor cost is almost less than 8% of the total costs. But in opposite side overhead cost is higher than before because extensive usage of machineries. As shown in Table 1 and 2, any changes in a product mix can mislead and extra addition any other product costs, if direct labor saving took for product B, so product A will bear extra cost of overhead because of changes in product B, in-fact no changes in product A process. The most advanced level in the lean production is “Four Wall” Transfer to finished products and vendor receipts. The control requirements of four walls are: Continuous product flow, short lead time and few scrap.
