| Research Abstract |
One of the major problems in manufacturing is to reduce cost. To do so, various activities such as Total Productive Maintenance (TPM), Total Quality Management (TQM), Industrial Engineering (IE) and Just-in-Time (JIT) are often carried out. However, many companies recognize that these activities do not necessarily guarantee cost reduction even if they have been implemented successfully. In the worst case, manufacturing cost rises with the introduction of such activities. This is an important issue in manufacturing, but strangely in the academic literature there have been no studies that have been addressed directly to the methodology of manufacturing cost reduction. The aim was to develop a good method that establishes a cost-reduction programme scientifically and systematically. A simple algorithm to establish a cost-reduction programme was developed in the following way :
Investigating various production losses and classifying them into causal losses and resultant losses.
Looking for the relationship among the losses, their processes-generating cost and the cost factors. Finding the connection between various kinds of loss reduction and their possible cost reduction is important.
Clarifying if the knowhow on each loss reduction is available and if not obtaining it if not available.
Estimating the cost of reducing or eliminating each identified loss and putting priority to the loss items for the total cost reduction from the viewpoint of cost and benefit.
This method has been coined as manufacturing cost deployment because a process leading to cost reduction is deployed based on the programme from the above four points.
