| dc.description.abstract | In order to decrease air pollution and disturbing noise, beautify the environment, ecological landscape and promote recreational activities, each government institutions and county government agencies set up new parks and green land as their significant developments policy to raise the living quality of people. In consideration of landscape and ecosystem, the park has generally been designed with green lawn in a larger proportion, providing space for the general public taking rest or doing activities. Lawn with a big area requires constant cares and trimming, whose jobs are normally handled by assigned maintaining agencies or employed workers. However, the assignment job of mowers and workers can be trivial so mostly owners or foremen arrange such jobs according to their experiences rather than scientific methods and systematic analysis for making comparison and assessment. It ends up causing inefficiency and waste of resources that truly requires exploration and study.
This research is applicable to the green land in a big area, or independent park with a large quantity of green land. Take the River Side Park in Taipei County as an example, integral lineal planning can be used as structure to develop a set of mathematic optimum mode. Through mower tools designed for suitably area of the lawn, tool working efficiency, cost and resources, LINGO package software can be applied to seek its minimum cost of the tool assignment. This mode can work together with the amendment of related parameters and limit formula according to the environmental change and its features at the site to serve as reference for related resource assignment and scheduling. | en_US |
