Procedure Followed
1.Look up at the daily running conditions( Feeder
Speed, Screw speed).
2. What is the history of running the same product.
3.Try to increase the feeder speed and accordingly
make changes in other parameters (Cooling Belt
speed)
4. Identify the constraints
5. Analyze the changes the throughput.

Recommendations
 Find the solution for the problem of backing up of material in the hopper.
Equipment modification such as Design changes in screws.
 Better Cooling system.
Maintenance of sprinklers
Design modification
 Better Communication with the operators.
Need to work with engineer to develop new run conditions for the machines as per the data
collected for last 3 months.
 We should work on the ACMs to increase the Throughput by analyzing various run conditions.

COMPLETE ANALYSIS OF
PRODUCT WHEEL
10
Axalta Coating Systems
Background
Presently Bucket sequencing is followed at the site.
The products are sequenced on the weekly bucket basis as per the demand .
In this process cleaning has to be done more often. This increases the productivity cost.
Wheel sequencing is sequencing of products as per consistent cycle. It helps in reducing the
cleaning time, inventory cost and in turn total production cost.
11
Axalta Coating Systems
To understand if Wheel sequencing will be Beneficial?
What is Product wheel?
Production sequence used by a manufacturing operation when multiple products are made on a
single line/piece of equipment
 Consistent sequence
 Repetitive time cycle
12
Axalta Coating Systems
Benefits
 Decreases controllable fixed costs
 Provides framework for establishing customer order lead times
 Provides understanding of relationship between transition cost and inventory cost

Product Wheel Analysis
Extruder - 3 Comparison of bucket sequencing and Wheel sequencing
Axalta Coating Systems
Results:
From monthly analysis we see some improvement are in Feb, March with 3 week buckets, but April worse, May
improved…so not clear there’s been a sustained improvement.
With Product wheel the transition rate is constant at 0.14 hrs/1000 lb.

Summary by Wheel length for E3
Overall costs look pretty flat across the
various wheel lengths (savings in cost are
balanced by increase in inventory)
Note that both Safety stock and Cycle
stock go up with wheel length
Note that current # FPO’s tracks to about
40 day wheel length, although inventory is
higher here…same is in Safety stock
(because of longer lead times)
Min wheel lengthWheel = 20 Wheel = 40 Wheel = 60

On each Extruder Amount Produced = 130,000 lbs/week
For 3 Extruder = 390,000 lbs/Week = 1.56 Mill lbs/Month
Cleaning time savings = 0.02 hrs/1000lb
= 31.00 hrs/ Month = 372 hrs/Year
So implementation depends on the business strategy.
From production side there are good savings.
From supply chain side the inventory increases. But total cost remains the same.

    Axalta Coating Systems Recommendations Find the solution for the problem of backing up of material in the hopper. Equipment modification such as Design changes in screws.  Better Cooling system. Maintenance of sprinklers Design modification  Better Communication with the operators. Need to work with engineer to develop new run conditions for the machines as per the data collected for last 3 months.  We should work on the ACMs to increase the Throughput by analyzing various run conditions. 9

    Axalta Coating Systems COMPLETEANALYSIS OF PRODUCT WHEEL 10
  • 11.
    Axalta Coating Systems Background PresentlyBucket sequencing is followed at the site. The products are sequenced on the weekly bucket basis as per the demand . In this process cleaning has to be done more often. This increases the productivity cost. Wheel sequencing is sequencing of products as per consistent cycle. It helps in reducing the cleaning time, inventory cost and in turn total production cost. 11
  • 12.
    Axalta Coating Systems Tounderstand if Wheel sequencing will be Beneficial? What is Product wheel? Production sequence used by a manufacturing operation when multiple products are made on a single line/piece of equipment  Consistent sequence  Repetitive time cycle 12
  • 13.
    Axalta Coating Systems Benefits Decreases controllable fixed costs  Provides framework for establishing customer order lead times  Provides understanding of relationship between transition cost and inventory cost 13

  • 18.
    Axalta Coating Systems Results: Frommonthly analysis we see some improvement are in Feb, March with 3 week buckets, but April worse, May improved…so not clear there’s been a sustained improvement. With Product wheel the transition rate is constant at 0.14 hrs/1000 lb. 18

    Axalta Coating Systems Summaryby Wheel length for E3 Overall costs look pretty flat across the various wheel lengths (savings in cost are balanced by increase in inventory) Note that both Safety stock and Cycle stock go up with wheel length Note that current # FPO’s tracks to about 40 day wheel length, although inventory is higher here…same is in Safety stock (because of longer lead times) Min wheel lengthWheel = 20 Wheel = 40 Wheel = 60 Boilerplate capacity (lbs/day) Target % Uptim Calc'd Min Wheel length Wheel length (prod days) 16 20 40 60 Max batch load size 4000 4000 4000 4000 Max fpo time coverage (prod days) 130 130 130 130 Operator hours in each test cycle 1.21 1.21 1.21 1.21 # Operators for transitions 4 4 4 4 Yield loss % on first bx of fpo 2% 2% 2% 2% Annual FPOs 584 503 289 202 Annual batches 1430 1430 1430 1430 Annual machine utility 74% 71% 62% 58% # Operators (load, ettr, test, acm) 8.8 8.7 8.1 7.9 Annual Transition hrs/ 000lb 0.13 0.11 0.06 0.05 Cycle stock (lbs) 193665 231206 434404 644840 Safety stock (lbs) 254148 284146 401844 492156 Labour cost $661,237 $649,504 $610,266 $594,313 Yield loss value $61,548 $53,091 $30,454 $21,155 Inventory value $596,853 $685,652 $1,108,257 $1,504,198 Inventory CC $101,465 $116,561 $188,404 $255,714 Total cost $824,249 $819,156 $829,124 $871,182

    Axalta Coating Systems20 On each Extruder Amount Produced = 130,000 lbs/week For 3 Extruder = 390,000 lbs/Week = 1.56 Mill lbs/Month Cleaning time savings = 0.02 hrs/1000lb = 31.00 hrs/ Month = 372 hrs/Year So implementation depends on the business strategy. From production side there are good savings. From supply chain side the inventory increases. But total cost remains the same.
