Description

A simulation model was developed to study on operation in various pipeline milkers in a cow shed. The performance of the milker was simulated for one operator under various conditions, and the predictive equation was established in order to estimate the performance of pipeline milkers easily.<br>The results are as follows:<br>1) Average milking time in the herd and number of milker units are most important factor in determining the performance of the pipeline milker.<br>2) When average milking time in the herd is more than 2min.×number of units, average milking time is important factor, but when it is less than 2min.×number of units, preparation-work-time and after-work-time are important factors. 3) The number of milking units by one man operation is below 3 units. When it has to use 4 units, it is nesessary to set the automatic cluster removal.<br>4) The coefficient of variation of the milking time in the herd and herd size are less important for the performance in the pipeline milker.<br>5) If two men are engaged milking work, it is better for performance of milking that they share the number of cows rather than they share the progress of work each other. But there is little difference between them.
