Estimation model of economically useful life of rice combine harvesters
Main Article Content
Abstract
The estimation model based on MATLAB/Simulink was estimated the economically useful life of rice combine harvesters. Result revealed systematically estimated the economically useful life using a sample of rice harvesters in the rice-growing region of Northeast Thailand. The findings revealed that the economically useful life of locally-made rice harvesters that was approximately for 10 years with 12,433 rai (7,460 hectares). The machines are still operated after 10 years, but it is costlier operated. The novelty of research proved the use of MATLAB/Simulink in the estimation model, as opposed to SPSS which is conventionally used to exist the estimation methods of other agricultural tools and machinery. The MATLAB/Simulink is compatible with a number of programing languages, and allowd for further development into web-based applications to use and greater user accessibility. Furthermore, the MATLAB/Simulink estimation model with minor modifications is applicable to other geographical areas, and rice combine harvesters.
