  • Flexibility, in the context of manufacturing, refers to an ability to accommodate changes in market requirements in terms of product, process, and other services in a timely manner at a reasonable cost. The basic purpose of this paper is to analyze manufacturing strategies of leading Korean manufacturers in order to answer the following questions : How important are manufacturing flexibilities to Korean companies in restoring their once competitive cost-based strategies and adopting new variety-based strategies\ulcorner How effectively are Korean companies competing with their foreign competitors, like the US and European companies in terms of manufacturing flexibilities\ulcorner And in order to improve the flexibilities what kinds of manufacturing capabilities are considered as important key factors by Korean manufacturers and are their action programs effectively implemented to acquire these capabilities\ulcorner Major findings of the analysis indicate that Korean companies are very eager to reorganize their high-volume, cost-based corporate strategies as low volume, variety-based strategies. However, Korean manufacturers are still much dependent on the large size high volume factories and / or 'focus factories'. And the action programs and technologies to improve manufacturing flexibilities have been actively implemented at a higher rate than those of their foreign counterparts.

  • In the automated manufacturing systems, the problem regarding how to make production activities flexible is even more important and critical than that regarding how to product large quantities, and the more flexible, if possible, the manufacturing system is, the more competitiveness and profitable factors it gets. This research, therefore, concentrated on establishing the flexibility and evaluating performance on the manufacturing system, operational flexibility is considered because of enabling the manufacturing system to get both the improvement of production rate and the adaptive ability of environment changes. For it, we used the analytical tool, GSPNs, which is a kind of timed Petri-Nets. GSPNs is competent enough to consider practical situations just like operation priorities, machine failure, randomness, concurrency and so on. Through the GSPNs analysis, it is confirmed that in the manufacturing system with operational flexibility is compatible with the traditional performances such as production rate or mean waiting time.
