| Proportional hazard regression model is the method most commonly because they are not based on the assumption that focus on the shape of the survival distributions available. Proportional hazard models including semi-parametric baseline hazard because it can use any shape and covariates entered the model linearly.This study aimed to determine and analyze maintenance intervals on a machine stamping dies. The variables that affect the brand variables, variable types of dies, and also the variable type of treatment. The method used for this study was proportional hazard method (PHM), The results showed that the variables that affect not follow a particular pattern or trend, it can be seen from the trend test testing using Mann-Whitney test using SPSS19. In addition, from the existing treatment EXP value fi of cox regression testing as well as the value offi.Of all the values obtained, it is also be obtained to determine the value of life time maintenance intervals on a machine stamping dies with 90% reliability level. |
