In today's challenging and turbulent competitive markets, companies need to constantly review their strategies in order to survive and sustain their market positions, especially the manufacturing ones. To remain competitive in the market, companies need to be continuously seeking innovative and effective management techniques. Just-in-Time (JIT) is one such management technique that increases the productivity of the enterprise by eliminating all kinds of wastes through continuous improvement. This paper is mainly a comparative study of the techniques, Simple Additive Weighting (SAW) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), for the ranking of performance indicators on the basis of various JIT elements in various industries. In this paper, six performance indicators are mainly used. If selection of these performance indicators is not done properly, it would affect the productivity of companies adversely. The main objective is to compare the rankings of the performance indicators of supply chain in various industries, obtained using SAW and TOPSIS techniques. [ABSTRACT FROM AUTHOR]
