【正文】 s journey. It enables identification of waste, consideration of whether the process can be managed more efficiently, consideration of better flow pattern and consideration of whether all activity is necessary. 流程活動(dòng)圖 ?流程活動(dòng)圖方法 1） Identify each step in the process and number them from the 1 at the top of the page to the final step at the bottom. 2） Next to the step number enter a brief written description of that step. 3） Define each step according to a pre defined list of categories. For example: Operation Transport Inspection Storage Delay 流程活動(dòng)圖 4） Record the time taken for each step 5） Record the time in each step that adds value to the patient 6） Record the numbers of patients waiting between each step 7） Record the number of people involved in each step 8） Determine if a particular type of equipment is needed at each step 流程活動(dòng)圖 ?流程活動(dòng)圖分析 A simple starting point is to ask the following questions of each step: 1） what needs to happen? 2） why does it need to happen? 3） when ought it to happen? 4） who ought to perform the step? 5） where ought it to occur? 6） how ought it to occur? 流程活動(dòng)圖 ?流程活動(dòng)圖示例 供應(yīng)鏈反應(yīng)矩陣 ?供應(yīng)鏈反應(yīng)矩陣（ Supply Chain Response Matrix）， also called as “ time based process mapping” 1） Diagram shows the critical leadtime constraints for a particular process. 2） This will be the cumulative lead time in a distribution pany, its suppliers, and retailer. 3） Cumulative lead time = 42 working days (x axis) 4） 99 working days of material held in the system( yaxis) 5） Total response time In the system= 141 days. 6） Each of the individual lead times and inventory amounts can be targeted for improvement. 供應(yīng)鏈反應(yīng)矩陣 生產(chǎn)多樣性漏斗 ?Production Variety Funnel ? Approach originated in operations management area ? Similar method to this is the I,V,A,T analysis ? I,V,A,T Analysis? ? Views internal operations in panies that conform to I,V,A or T shapes. ? I – unidirectional, unvarying production of multiple items ? V limited number of raw materials, wide variety of finished products ? A Many raw materials, limited finished products ? T Wide bination of products from few ponents 生產(chǎn)多樣性漏斗 Advantages of classifying products on IVAT basis ? To understand how the firm or supply chain operates ? How to manage the plexities associated with the supply chain. ? Helpful in deciding where to target inventory reduction and changes to processing of products. 質(zhì)量過(guò)濾圖 （ Quality Filter Mapping） ? New tool designed to identify where quality problems exist in the supply chain. Different types of quality defect ? Product defects not caught up in line ? Service defect inappropriate delivery, documentation etc. ? Internal Scrap caught up inline or endofline. Each of these defects are then mapped to identify the source of defects and ways to correct it. 質(zhì)量過(guò)濾圖 （ Quality Filter Mapping） 需求擴(kuò)大圖 （ Demand Amplification Mapping） ?This simple analytical tool can be used to show how demand changes along the supply chain. 需求擴(kuò)大圖 （ Demand Amplification Mapping） ?Information from the graph ? Can be used for decision making and further analysis. ? Help to redesign the value stream configuration ? Manage fluctuations ? Reduce the fluctuation 決策點(diǎn)分析 （ Decision Point Analysis） ?Particularly used for T plants Wide bination of products from few ponents What is a decision point? ?Decision point is the point in the supply chain where actual demand pull gives way to forecast driven push. ?Products that are made according to actual demand are produced by for
