Courier services are currently multi-billion-dollar earning industries which help the wheels of business to turn smoothly. With the rapid development of e-business, shorter product and technology life cycles and higher customer expectations, courier service has become more and more popular. Obviously, online sales increased sharply worldwide over the past decade. Traditionally, a courier company delivers messages, packages and mail. A courier service is distinguished from an ordinary mail service by features such as speed, security, tracking, signature, specialization and individualization of services, and committed delivery time which is optional for most everyday mail services. Even with the adaptation of recent technologies to ensure the quick delivery of products at a reasonable cost, most courier companies are poorly rated by customers, especially in social networking sites.
