Fast and flexible low-cost data processing and information systems have transformed business operations. Through enhanced information availability, leading manufacturers have accelerated the flow of their products to create competitive advantage based on speed. These companies have developed methods to channel the power of information in order to use organizational resources more effectively and facilitate the management of activities both within and outside the company [1,2]. Internally, interactions between areas such as production and sales can be more closely co-ordinated with the aid of information support. Externally, information availability can result in enhanced service and promote better relationships with supply chain partners. Planning and scheduling systems have been used to manage operations throughout the pipeline. Subsequent reductions in production setup times, lot sizes, and inventory levels have yielded productivity and efficiency improvements [3,4].Changes have been especially dramatic with respect to logistics. Today, logistics is a high-tech process dependent upon information to support planning, operations, and control throughout a firm's supply chain [5][6][7]. In 1992, logistics costs represented approximately 11 per cent of the US gross domestic product[8].
