Competitiveness powered growth of a secure supply chain through the c-tpat program

Аннотация

This study estimates the competitiveness level among the different modes of transportation (vessels, air carriers, trucks, rail containers and other type) used by a secure supply chain, which had been implemented the C-TPAT program; the Customs-Trade Partnership Against Terrorism is a federal-government-program launched in November 2001 with seven initial U.S. large companies as participants; the C-TPAT program benefits are presented. An analysis of variance (ANOVA) reveals a significant difference (p-value=0.001) among the modes of transport with respect to the average import value; a graphical confirmation (box-plot) is shown for this case. Applying a statistical procedure for data standardization via the Z-score, this article shows the contribution (additive effect) to the competitiveness level of the dissimilar modes of merchandise transport from two factors: the import value in millions of dollars, and the annual percent growth rate of such import value; where the number of C-TPAT validations and revalidations per year has been showing a curvilinear competitiveness powered growth (p-value=0.001).
