This study aimed to analyze the replacement investment of the diesel fuel system with the pallet fuel system in the Korean farming sector. Equivalent annual annuity approach was used to resolve a discrepancy of useful life in capital goods and to facilitate investment analyses in an independent perspective. Data was obtained from previous studies on economic analysis of greenhouse tomato, paprika and cucumber. Results showed that the replacement with the pallet fuel system was acceptable irrespective of the remaining period of useful life for the diesel fuel system. In addition, sensitivity analysis with government support level, repair cost, and light and heat energy cost show ed robustness in the possibility of replacement with the pallet fuel system while the speed of replacement was accelerated with an increase in the amount of diesel fuel used and price of diesel fuel, and a decrease in price of the pallet fuel. The result implied that the replacement investment rather than a new investment was appropriate for existing greenhouse farmers and the pallet fuel system was acceptable to replace existing diesel fuel system in producing greenhouse tomato, paprika and cucumber.

Many parallel lines may be shown in our real life and they are useful for analyzing structure of objects or buildings. In this paper, a vision based technique for estimating three-dimensional direction of parallel lines is suggested, which uses a calibrated camera and is applicable to an image being captured from the camera. Correctness of the technique is theoretically described and discussed in this paper. The technique is well applicable to measurement of orientation of a pallet in a warehouse, because a pair of parallel lines is well detected in the front plane of the pallet. Thereby the technique enables a forklift with a well-calibrated camera to engage the pallet automatically. Such a forklift in a warehouse can engage a pallet on a storing rack as well as one on the ground. Usefulness of the suggested technique for other applications is also discussed. We conducted an experiment of measuring a real commercial pallet with various orientation and distance and found for the technique to work correctly and accurately.

A common problem for manufacturing industries, especially consumer goods industries, is how to establish standardized procedures for loading finished goods onto pallets or containers for subsequent storage and distribution. Utilizing previous research results on the palletizing problem, this paper develops micro-computer based programs which generate an optimum loading pattern leading to the minimum amount of unused pallet or container space. Development of pallet layout chart is also included in the computer programs. The results are displayed by computer-graphic. For the users who are unfamiliar with pallet loading problem and computer system, pull-down menu and user-computer interactive data input procedures are adopted.
