A Study on Skip Flow Shop Scheduling Considering with a Cutting Process in Reinforcing Bar Manufacturing In recent years, technical innovation is also expanded in the field of housing construction. The unit basic reinforcing rod system (BRS) is one of important innovation of xe2x80x9clayout of reinforcement bar processxe2x80x9d in the making of the housing base. This process was performed by handwork in the past, many housing construction sites are using BRS at now. The BRS is made in factory and production process are complicated. Therefore, the process systematization is behind. A manufacturing premise of BRS is regarded as a flow shop system that the lot sizing condition is different every process. In addition, the first process of BRS is a cutting process. It is also important for making of BRS. In this study, an efficient scheduling method is proposed using the priority of the lot sizing condition and a cutting process.

Application of Lean Manufacturing Tools to Reduce Downtime in a Small Metalworking Facility This article analyzes the extensive downtimes found throughout the process of manufacturing metal structures, and how to minimize them in order to increase productivity. The overall process includes welding, beveling, and transfer to the assembly area, the three of which were identified as the most critical, because they have the highest downtimes. This downtime is generated by several factors, among which are a lack of order and cleanliness in the various work stations, and the absence of mechanisms to control production. A proposal was developed to improve the process of manufacturing brick dryer screens using Lean Manufacturing tools such as Kanban and 5u0027S to reduce downtimes and increase the profitability of the company. The results obtained through a simulation in Arena Software show an overall reduction of downtime by 62%.
