and cycle time by meeting the desired customer demand, which can help the hardwood industry, be more competitive. 7.3 PLANT C AND D FUTURE STATE VALUE STREAM MAP One of the objectives of the project is to determine how vacuum drying can impact the TH, CT and WIP of a flooring line production. According to the value stream maps mentioned in chapter 7, the drying process is the one that produced more inventories due to its lead time to dry lumber. According to the literature review in section 2.4, vacuum technology reduces the drying time of conventional technology by almost half, with the same quality and similar cost values as conventional. Due to this, one of the objectives of the research is to see how the WIP, throughput and cycle time can be impacted in the process. Simulation results presented in Table 36 and 37 in section 7.2. Showed that vacuum drying can reduce lead times, inventory and meet desired demand. The future state map for Plant C and D presents improvement in their lead times and inventory levels of the line production by using vacuum drying. For the future state, case B presented better results than Case A as shown in table 36 and 37 of section 7.2, and it was chosen as the scenario for the future state improvements for Plant C and D. The total lead times were reduced from 288 days to 8 hours and 4.03 min, which corresponded to a 96% reduction. Processing times of 54 days and 1 hour were reduced to 1 hour and 30 min, which represents a 98% reduction. Throughput met the daily demand of 1057 MBF. This means that costumer products are delivered on time. 116PDF Image | Impact of Vacuum-Drying on Efficiency of Hardwood Products
