XYZ is a manufactured company which produces shoes. This company has scheduling problem. Machine utilization and labor management is not manage and schedule properly. It will become a threat in the future for this growing company. Recently, scheduling is running by owner’s intuition. Thus, this research applied Fuzzy PERT and Lang’s Algorithm in the company for scheduling production. This research used information from the company to make scheduling by production time, production process and expert judgement. Production time used to measure standard time in shoes production. Expert judgment used to Fuzzy PERT, so the production total time with expert judgement can be define. Then, that two production total time become a Lang’s Algorithm input. Thus, this research can define optimization level between labor with nowadays production time. The comparison is between standard total time and Fuzzy Pert total time. The results from data processing define with the Fuzzy PERT method, production total time can be reduce. Standard time for shoes production is 1946,48 seconds or 32,44 minutes. Fuzzy PERT production time is 1835,12 seconds or 30,59 minutes. Through Lang algorithm analysis, it is not necessary to increase number of labor, because the difference of total time between standard time and Fuzzy PERT is not too significant. The production scheduling use the results from Fuzzy PERT method because the production time can be reduce 111,36 seconds or 1,86 minutes. The scheduling use 35 labors and 22 work stations.
