1. Ice Cream Social Kramerica Industries ISE 503 Final Project Dr. Lavender By, Austin Mount-Campbell RahulBansal Kramer Voigt Paul Kabakjian

2. Background on Project Jeni’s Ice Cream in Grandview Observed Ice cream scooper by the name of Jade Watched for: Postures Technique Work place arrangement Servicing of customers

3. Jade’s Job Service Customers Takes orders Scooping Ice Cream Blending Shakes and Smoothies Checking out customers *note all jobs done by her for the customer she serves in other words there is no kind of assembly line

4. Problem Areas Scooping Ice Cream Forehand Scooping Height of Ice Cream Refrigerators Height Countertops Height Blender Placement Distance

5. Risk Factors Assessment

6. Liftshitz and Armstrong Questions / Answers Can the job be done without contact of fingers or wrist with sharp edges? Yes Is the tool operating without Vibration? Yes Are the workers hands exposed to moderate temperature? No Can the job be done without using gloves? Yes Can the job be done without using finger pinch grip? Yes Can the job be done without bending (flexion or extension) of the wrist? No Can the tool be used without flexion or extension of the wrist? No Can the job be done without ulnar or radial deviation of the wrist? No Can the tool be used without ulnar or radial deviation of the wrist? No Can the worker be seated while performing the job? No Can the job be done without “clothes wringing” motion? Yes Can the orientation of the work surface be adjusted? No Can the height of the work surface be adjusted? Yes Can the location of the tool be adjusted? Yes Is the cycle time above 30 sec? Yes Can the thumb and finger slightly overlap around a closed grip? Yes Is the span of the tools handle between 5-8 cm? Yes Is the Handle of the tool made from material other than metal? Yes Is the weight of the tool below 10 lbs? Yes is the tool suspended? No Yes: 12 No: 8 Score: 12

8. REBA Scores Scooping Ice Cream As shown in last slide it is 7 Blending Milkshake REBA Score of 2 Passing Product to Customer REBA Score of 2 Cashiering REBA Score of 2

9. NIOSH Score Horizontal Multiplier= 10/H where H is equal to 18 inches. 10/18= 0.555 Vertical Multiplier= (1-(0.0075|V-30|)) where V is 36 inches. (1-(0.0075|V-30|))= 0.955 Distance Multiplier= (0.82 + 1.8/D) where D is 24 inches. (0.82 + 1.8/24)= 0.895 Asymmetry Multiplier= (1- 0.0032*A) where A is 0. (1- 0.0032*0)= 1 Frequency Multiplier= From Chart equals 1 Coupling Multiplier= From Chart equals 1 RWL= 51*0.555*0.955*0.895*1*1*1= 24.19 lbs. LI= (Load Weight/ RWL) = ≈25lbs./24.19 lbs.= 1.03

10. Workplace layout

11. New Layout

12. Ice Cream Layout

13. Conclusion REBA, NIOSH scores were no worry other than scoping which is also where Liftshitz and Armstrong showed concern We suggest changing scooping style And re-arranging workplace for added efficiency
