The implementation of PVRP is conducted by determining delivery quantity, delivery time, service time and transportation cost from warehouse to the retailer and between retailers that furthermore is entered in mathematical model and solution searching by using LINGO software. From the result of solution searching, it gives schedule, route and total cost. Visitation schedule after using PVRP method, for Malang downtown and Pakisaji, the schedule of visitation is conducted twice a week on the combination of Monday, Thursday and on Tuesday and Friday. For Pujon, there should be three times a week of visitation schedule; Monday, Wednesday, Friday and Tuesday, Thursday, Saturday.
