Logistics has been an important part of every economy and every business entity. Logistics cost average about 12% of the World’s GDP [1]. In Singapore, logistics cost accounts for about 11% of its GDP [2]. The worldwide trend in globalization has led many companies to outsource their logistics function to Third Party Logistics (3PL) companies, so as to focus on their core competencies. In a recent study [3] conducted by Cap Gemini Ernst & Young US LLC, Georgia Tech and Fedex, involving 400 representatives from North America, Western Europe and Asia Pacific, it is concluded that logistics outsourcing remains a growing business globally. On a smaller scale, Bhatnagar, Sohal and Millen [4] reported that the need for logistics outsourcing is also increasing in Singapore.
