Step #1 - Lean Manufacturing Used to Identify Waste In and/or Cause By the Manufacturing Process Lean is accomplished by identifying and eliminating waste (non-value added activities).
Lean Studies Used as Problem-Solving Techniques; VSM Findings Were Flushed Out Through Financial Analysis Percentage of Units Per Monthly Cost Annual Cost of Area Re-work Cost Month of Quality Quality Finesse 3% $1.50 6750 $10,125.00 $121,500.00 Touch-up 4% $2.04 9000 $18,360.00 $220,320.00 Repeat Op 3 4% $2.70 9000 $24,300.00 $291,600.00 Repeat Op 2 3% $4.81 6750 $32,467.50 $389,610.00 Totals 14% 31,500 $1,023,030.00 Scrap Percentage of Scrap Cost Units Per Monthly Cost Month of Quality Approximately 1 month of Production Per Year is Lost Due to Scrap and Re-work Annual Cost of Cost of Lost Monthly Cost Annual Cost of Quality Opportunity of Quality Quality Monthly Cost of Quality for Sales Annual Cost of Quality for Sales Op 1 3% $8.36 9,000 $75,203.67 $902,444.04 $45.16 $406,403.67 $4,876,844.04 462,068.67 5,544,824.04 Op 2 3% $11.56 4,500 $52,015.87 $624,190.46 $48.36 $217,615.87 $2,611,390.46 245,448.37 2,945,380.46 Op 3 3% $12.39 4,500 $55,776.06 $669,312.66 $49.19 $221,376.06 $2,656,512.66 249,208.56 2,990,502.66 Op 4 1% $15.18 4,500 $68,310.00 $819,720.00 $51.98 $233,910.00 $2,806,920.00 261,742.50 3,140,910.00 10% 22,500 $3,015,667.16 $12,951,667.16 14,621,617.16 VSM Findings: *14% Rework *10% Scrapped & Reprocessed *1% Scrap at Each Major Dept. *1 Day WIP *3 Days Receiving Inventory *3+ Months of Finished Goods *First Time Thruput < 60%
Step #2 MES Manages the Shop-Floor Through Improved Data Collection; Provides Improved UI over ERP System A MES is a Mechanism for Continuous Process Improvement through its capability to capture it s planned and actual production data (Cause and Effect). What to Build Mechanism How to Build What was Built As-Planned For CPI As-Built How was it Built
The Architecture Demonstrates the Ability of MES to Provide the Right Information, to the Right Resource, at the Right time for Action, Enabling CPI Enterprise Factory Process/Line Recipe/Machine As-Built Product & Process Demand Product & Process Data Definitions ERP EDM / PDM Production Status Production Orders Product & Process Data Definitions CPI Execution Systems Consumption Results & Status Set Points Shop Packet Picklist Verification & Traceability Work Status Production, Quality, & Maintenance Controls People Inventory Manufacturing Process Alarms History Data Readings & Parameters Equipment As-Planned
Step #3 - Knowledge Gained by 6 Sigma Methodology to Reduce Variation May be Applied to MES to Enhance CPI Capabilities A Pareto of Top Manufacturing Defects was Identified. Defects Highlighted in RED are Caused During the Casting Process, Accounting for Half the Total Defects. 5.0 1.0 6σ Methodology 2.0 1.0 2.0 3.0 Define Opportunity What is Important? Measure Performance How are we Doing? Analyze Opportunity What is Wrong? 16000 12000 8000 Methodology Applied By Exploring Top Manufacturing Defects 4.0 3.0 4.0 5.0 Improve Performance What Needs to be Done? Control Performance How do we Guarantee & Sustain Performance? 4000 0 Shrink Spoke Pinholes Hand Rim Cast Pit Hand Cast Other
Step #4 An Event Driven Response System Manages Production to Meet Actual Customer Demand 1.35 1.15 0.95 0.75 0.55 0.35 93 94 95 96 97 98 99 2000 2001 2002 2003 2004 Synchronized Manufacturing Demand Volatility Results In: Based on Dynamic Demand Variability in Manufacturing Lead-Times Uncertainty in Order Commitment Quantity and Delivery Dates Dependent on Production Resource Availability Need to Address Product Variation in Planning/Scheduling
The Sense & Respond System Optimizes Planning & Scheduling and Reaction to Dynamic Customer Demand React and Plan on Real-Time Basis to Dynamic Business Conditions, Optimizing the Orchestration of Business Activities Consumer Retailer Wholesaler Distribution Manufacturer Supplier
The 4-Step Approach Achieves Sustained CPI Through Lean, MES, Six Sigma, and Sense & Respond, Increasing Production Yields & Reducing the COGS 4-Step Approach Waste Elimination Mechanism For CPI Overall Expected Results 2 Months Additional Production Yields Per Year No Additional Facility Resources Required All Elements Working Together as a Well Oiled Entity Variability Reduction Optimization of Customer Order Fulfillment Process
