Item An Analysis of Intermodal Railroad-truck Freight Transportation Facilities and Services in Minnesota(1991-12) Harper, Donald V.; Evers, Philip T.The general objectives of the study reported on here were to identify the Intermodal railroad-truck (IRT) facilities and services available to manufacturers in Minnesota, the extent of use of IRT service by those manufacturers, the characteristics of the users, and the perceptions of users and nonusers about the service and its cost. The study concluded that IRT facilities and services are sufficiently available to Minnesota manufacturers and other shippers and receivers in the state, within the limits of IRT service regarding the location of origin and destination points and shipment size. Minnesota is probably served as well as any state is currently being served by IRT.Item The Impact of the Use of Just-in-Time on the Use of Inbound Transportation by Manufacturers(1989-11) Harper, Donald V.; Goodner, Karen S.Transportation is a critical element in any JIT system and several transportation practices can be affected by the need to support a manufacturer's inbound JIT system. These include increased importance attached to inbound transportation, a shift in who has control over inbound transportation, the size of and frequency of shipments, the lengths of haul, the mode and carrier choice, the number of carriers used, and vehicle utilization. In addition, energy consumed in transportation and transportation costs can be affected. The objectives of the mail and personal interview study reported on here were, first, to determine the extent to which manufacturers in Minnesota and Wisconsin have adopted the JIT concept for inbound movements and what kinds of firms they are in terms of size, products produced, and plant location. The second objective was to determine, for those manufacturers included in the study, why they did or did not adopt the JIT philosophy. The third objective was to determine to what extent the implementation of inbound JIT caused a change in the use of transportation. The study was a preliminary study in that it was intended to provide information that could be used as a foundation for a more detailed study later.Item Just-in-time and the use of transportation by Minnesota and Wisconsin manufacturers(1991-02) Harper, Donald V.The objectives of the study were to determine (1) the extent to which manufacturers in Minnesota and Wisconsin have adopted the JIT concept for inbound or outbound movements; (2) what kinds of firms can successfully use JIT in terms of their size, plant location, products produced, and type of manufacturing (repetitive or non-repetitive); (3) for those manufacturers that have adopted the JIT philosophy, what their reasons were for doing so and, for non-users of JIT, why they had not done so; and (4) to what extent the assumptions concerning the use of transportation in a JIT environment are supported by the experience of manufacturers in Minnesota and Wisconsin, i.e., what was the effect of their participation in JIT on their use of transportation. The study, conducted in 1989-1990 followed a preliminary study conducted in 1988-1989.Item Transportation facilities and services available to Minnesota exporters to serve Pacific area markets(1993-07) Harper, Donald V.The transportation facilities and services available to Minnesota exporters to export to Pacific area countries were identified. This included the modes of transportation, individual carriers, third parties, and ocean ports and airports available to Minnesota shippers. The service provided was evaluated as were its accessibility to Minnesota exporters and the ability of the system to handle a substantial increase in exports from Minnesota. Included were international water and air transportation and domestic railroad, motor truck, and intermodal railroad-truck transportation. The conclusions drawn were that (1) the transportation service from Minnesota to the Pacific area is sufficient in quantity and quality in all modes, with some problems with lack of enough air freight service at Minneapolis-St. Paul; (2) the transportation service is satisfactory in terms of cost for water and motor truck service, with less satisfaction with the cost of the other modes; (3) the transportation service is generally accessible to Minnesota exporters; and (4) the transportation system for the most part should be able to handle a major increase in the quantity of exports to the Pacific region from Minnesota, the possible exception is air freight transportation in terms of both carrier capacity and airport capacity.Item Transportation of Energy in Minnesota: Review and Analysis(1989-06) Harper, Donald V.The purpose of the study reported on here was to investigate and analyze the energy transportation system in Minnesota in order to identify what the system consists of and how energy sources' are transported to and within the state, and to evaluate the system and to make recommendations for state policy on the matter. It is hoped that the report will be useful to producers, distributors, and users of energy and those who perform energy transportation service, and to government agencies responsible for promoting and/or providing and/or encouraging private investment in transportation facilities in Minnesota.
