Toyota Kata – Process Analysis. Assess Customer Demand and Determine Line Pace评估客户需求及设定节拍 Toyota Kata – Process Analysis. Two numbers that you must know. 以下2个一定要清楚的数字” 1 Takt Time (TT) Aka Customer Takt The customer demand rate 客户节拍时间 2 Planned Cycle Time (Pc/t): 计划加工周期 The target production rate, which is different from the customer demand rate.目标的生产节拍和客户节拍不同 (Usually faster, as it accommodates changeover time and perhaps some downtime)通常更快,因为包含了换型,和停机时间 Calculate the Takt Time计算节拍时间 The Heartbeat of Production生产的心率 The pulse reflects the customer’s requirement. 脉搏反映客户的需求 It is the rate at which you must produce to satisfy demand.这就是你必须生产而满足需求的速度. It is a calculated number, not a reflection of your capability. 这是计算出来的数字, 不是你产能的反映. It is the core concept for managing a JIT production system. 这是管理及时生产系统的核心理念. Toyota Kata – Process Analysis. Planned Cycle Time (Pc/t) 计划加工周期 Planned Cycle time is derived as follows: 计划加工周期的由来: Takt time minus Changeover time, other losses – ie unplanned downtime, scrap, rework. 节拍时间-换型时间-其它损失时间(非计划停机,报废,返工) Note this is the actual speed the line should be running. 注意这是我们实际应该跑的速度: Changeover time: In the first Pc/t calculation use the current number of C/O done per day and the total time it takes.换型时间 : 第一次计算PC/T用当前换型次数/天和消耗的总时间 Downtime: Two type of shortages. Short stoppages that add up during the day and rarer long stoppages due to breakdowns. Use only the short stoppages in the calculation.停机时间:两种停机: 一种是累加的微小停机,一种是长时间的停机,仅使用微小停机来计算. Note: try to strive for the Pc/t to be approximately 15% or 20% faster than the takt time. Loss time and changeover times need to be addressed to bring this into line 经验值:一般的PC/T比T/T快15%-20%,当导入后,需要进一步来解决停机和换型的损失. Toyota Kata – Process Analysis. The following simple Capacity Analysis using the L-Shaped stack chart is an exceptionally useful tool for calculating Pc/t. 接下来L形图是一个非常有用的产能分析工具. This should be mastered by everyone. 每个人都需要熟练掌握这个工具 In the stack show each category of losses individually
