#1 – Select Project:

IE 327 6 #1 – Select Project Human factors – Technical factors – Economic factors – Exploratory tools Pareto analysis Gantt chart Fish diagram Job/Worksite Analysis Guide

PARETO ANALYSIS (80-20 Rule):

IE 327 7 PARETO ANALYSIS (80-20 Rule) Vilfredo Pareto – economist 80% of money held by 20% of people 80% of costs, accidents, injuries, accounted for by 20% of jobs/individuals Concentrate on those 20% Plot in descending order as a cumulative probability distribution ( DesignTools )

GANTT CHART:

IE 327 8 GANTT CHART Horizontal bar chart of activities Shade in bar as completed Any given point in time, a snapshot of the status of all activities Some behind, some ahead of schedule Again focus efforts where needed Use DesignTools

JOB/WORKSITE ANALYSIS GUIDE:

IE 327 10 JOB/WORKSITE ANALYSIS GUIDE Time to go out on the floor Meet with supervisor first Explain study (production?) Select jobs/workers May need to meet with union also Never express opinions Fill out Job/Worksite Analysis Guide

METHODS STUDY (NEXT?):

IE 327 13 METHODS STUDY ( NEXT? ) Get and present data Analyze data Develop ideal method All of these overlap Use special charts or procedures Quicker, more efficient Designed specifically for IEs

Slide 14:

IE 327 14 Charts using sequence only Operation (outline) process chart Flow process chart Two-hand process chart Charts using time Multiple activity chart Simo chart Charts indicating movement Flow diagram Travel chart Motion analysis

PROCESS CHARTS:

IE 327 15 PROCESS CHARTS Record sequence of flow for worker, material, or tools/machines Outline (operation) vs flow Supply basic information: date, job, worker ASME symbols for activities (shorthand) Vertical lines – main flow Horizontal lines – subcomponents to main Summary – compare before and after
