富通LGS结构公司为埃德蒙顿的住宅提供了一种轻型钢结构（LGS）建筑选择 和商业市场。由于富通的工厂同时为多个项目运营， 该团队已经认识到，开发一个衡量工厂生产率的系统至关重要 生产，在此基础上，精益原则可以应用于改进。目前， 存在的挑战是针对这项研究：（1）目前的制造工艺缺乏一个连续的 流动，导致生产过剩和延迟。目前的进程还受到缺陷、缺陷、 （2）工具和设备的使用效率低下，许多非增值活动存在于 （3）资源均衡在整个过程中不一致，未能考虑到不同的 每个站的周期。为了衡量和提高富通生产线的生产率， 建议的研究旨在解决以下目标：（1）收集当前生产过程的数据： 将进行时间研究，以获取生产工艺的当前状态。(2)生产 过程改进：基于生产线的当前状态VSM，团队将专注于 提出改进过程的潜在解决方案。最终，未来状态价值流图（VSM）是 预计将在富通的生产中实施和模拟。(3)“检查和行动”：拟议的 研究将遵循计划-执行-检查-行动（PDCA）流程。 拟议项目预计将带来以下环境，社会经济和健康效益， 加拿大人：（1）提高生产力，节省非现场制造成本;（2）减少 与住宅/商业建筑相关的温室气体（GHG）排放和CO2足迹;（3） 建立代表“最佳实践”且安全的标准操作程序（SOP） 人体工程学视角

Fortis LGS Structures Inc. provides a light-gauge steel (LGS) construction option for Edmonton's residential and commercial market. As Fortis's factory operates for multiple projects simultaneously, the management team has come to recognize that it is critical to develop a system to measure productivity for the factory production, based on which Lean principles can be applied for improvement. At present, the following challenges exist that are targeted in this research: (1) the current manufacturing process lacks a continuous flow, which results in overproduction and delay. The current process is also hampered by deficiencies, defects, and rework; (2) the tools and equipment are used inefficiently and many non-value added activities exist in the process; and (3) resource levelling is not consistent throughout the process, failing to account for the different cycle times for each station. In order to measure and improve the productivity of Fortis's production line, the proposed research aims to address the following objectives: (1) Collect data for the current production process: Time study will be performed in order to capture the current state of the production process. (2) Production process improvement: Based on the developed current-state VSM of the production line, the team will focus on proposing potential solutions to improve the process. Ultimately a future-state value stream map (VSM) is expected to be implemented and simulated in Fortis's production. (3) "Check-and-Action": The proposed research will follow a Plan-Do-Check-Action (PDCA) process. The proposed project is expected to bring the following environmental, socio-economic, and health benefits to Canadians: (1) Improvement of productivity and cost savings for offsite manufacturing; (2) Mitigation of greenhouse gas (GHG) emissions and CO2 footprint associated with residential/commercial construction; (3) Establishment of Standard Operation Procedures (SOPs), that represent "best practice" and are safe from an ergonomic perspective.
