Creating the Logistics Vision Nowadays,most companies are familiar with the idea of "mission statement"as an expression of setting a vision for the business.The mission statement seeks to define the pur-pose of the business,its boundaries and its aspirations.It is now common for organizations to have such statement for the business as a whole and for key constituent components.What some companies have found is that there can be significant benefits to defining the lo-gistics vision of the firm. The purpose of the logistics vision statement is to give a clear indication which business intends to build a position of advantage through closer customer relationship.Such state-ment is never easy to construct.There is always the danger that they will publish the ener-getic and encouraging declaration that give everyone a warm feeling but provide no guideline for action. Ideally the logistics vision should be built around the simple issue of"How do we intend to use logistics and supply chain management to create value for our customers?"To realize this idea will necessitate a detailed understanding of how customer value is created and deliv-ered in the market in which the business competes.Value chain analysis will be a fundamen-tal element in this investigation as will the definition of the core competencies and capabilities of the organization.Asking the question"What activities dowe excel in?"and"What is it that differentiates us from our competitors?"is the starting point for creating the logistics vision statement. Earlier,it was suggested that the three words"Better,Faster,Cheaper"summarizes the ways in which logistics vision statement can provide value for customers.The criterion for good logistics vision statement is that it should provide the road map for how these three goals are to be achieved． Questions:

A:Transportation. B:Costs. C:Customers. D:Punctuality.

Typically, these are concern with the establishment of （） the network and with the control of the flow of messages across this channel. The provision of such facilities is only part of the network requirements, however, since in many applications the communicating computers may be of different types. This means that they may use different programming languages and, more importantly, different forms of （） interface between user(application)program, normally referred to, as application processes or APs, and the underlying communication services may be （） For example, one computer may be a small single -user computer, while another may be a large （） system. In the earlier days of computer communication, these issues meantthat only closed communities of computers ( that is, from the same manufacturer) could communicate with each other in a meaningful way. IBM’s Systems Network.
Architecture (SNA) and DEC’s Digital Network Architecture (DNA) are just two examples of Communication software packages produced by manufacturers to allow their systems to be int erconnected together. These proprietary packages, however, of which there am still many inexistence, do not address the problem of universal interconnect ability, or open systems interconnection. In an attempt to alleviate this problem, （） , in the late 1970s, formulated a reference model to provide a common basis ( or the coordination of standards developments and to allow existing and evolving standards activities to beplaced into perspective with one another.
