This project analyzes this scenario for Weatherford Aerospace, LLC, addressing company management’s concern over the lack of a roadmap for production workers to promote within the company. The project was broken into two initiatives: The first, an Operator Skills Matrixand the second, an Certified Operator Training Program. The initiatives together, constitute the project team’s solution to the personnel issue experienced at the company.
Organizations today face a recurring dilemma, the issue being mutual between management and production. Production workers often feel as though their jobs have no clear path for growth, and managers are left within unclear guidelines on how to promote. The question has been proposed: Is there a defined system for how an employee can move through the ranks of the company?
The scenario for Weatherford Aerospace, LLC, follows this description. Management is concerned with the lack of a “roadmap” for the production worker to move upward within the organization’s ranks. By developing a program that satisfies this need, managers feel they will have addressed an important employee need in retaining organizational talent.
DefineDevelop a path for the production worker to promote and improve within the company: Phase I – Create an operator skills matrix to define requirements for individual skill levels.Phase II – Develop an Operator Self-Verification Program to reduce emphasis on traditional inspection techniques.

2. Implementation of Certified Operator Training Program
1. Certifies highly skilled operators to verify their own work
2. Reduces Emphasis on Traditional Inspection Techniques
3. Expands departmental training regimens
The project implements two tools with the goal of providing a roadmap for the production worker to promote within the company. This is accomplished by creating two training programs complete with objective constraints, as well as developing a brand new program to train operators to verify their own work.
By implementing these tools, the company will have clear stepping stones for their employee’s manufacturing careers. It is predicted that with continued project dedications, the company will see a significant drop in production worker attrition rate and employee training time.

IE 4350 Capstone – Spring 2017
Patients at Harold C. Simmons Cancer Clinics aredissatisfied with their overall visit experience interms of wait time and scheduling conflicts.Quantitative data and observations yieldedundesirable wait times, physical communicationbarriers between staff members, redundancies inthe check-in process, and batch patient scheduling.A Three-Part Check-In Redesign is recommended toreduce patient wait times throughout the clinicsalong with the installation of additional safetyequipment and amenities to increase patientsatisfaction.
The scope of the project includes: the 2nd floor main check-indesk, Infusion clinic, Labs, Breast/Surgical Oncology clinic,Hematology Oncology clinic, and Gastrointestinal/Genitourinary clinic. The patient flow throughout the hospitalis redundant in certain areas and, based on our observations,appears to yield little patient confidence and acceptance in thecurrent process. The main objectives are to improve thepatient experience throughout these areas, reduce wait time,and improve quarterly patient satisfaction reports. The currentpatient flow process is illustrated below:
Suggested Alternatives• Three-Part Check-In Redesign
1. Reduce responsibility of 2nd floor main check-in desk
2. Increase responsibility of 1st floor information desk
3. Allow individual clinics to check-in their own patients
• ADA Requirements/RecommendationsIncrease the number of Think-Lifts to one on each floor, install handrails in long hallways, install automatic handicap doors, and widen door frames for wheelchairs.
• Reallocating FundingThe 2 check-in kiosks collectively see 1.6% utilization on busy days. 3 possible financial alternatives:1. More recliners in Infusion clinic2. Waive 5$ valet fee for patients3. Install more Think-Lifts
• Clinic Specific SolutionsImplement One-Piece Flow patient processing procedure and eliminate task batching
Implementing the Three-Part Check-In Redesign wouldallow regular patients to go directly to their appointmentfloor which would reduce bottlenecking on the 2nd floorcheck-in and increase patient satisfaction by eliminatingredundant process steps. Subsequently, increasing theworkload of CSA’s at each individual clinic by enablingpatient check-ins would: increase utilization, reduceemployee down time, and increase CSA job enrichment.Qualitative suggestions based on observations (ADAimprovements, Kiosk alternatives, etc.) provide thestakeholders with additional improvement alternatives thatwould add to the overall patient experience.

Kubota Tractor Corporation’sNorth American DistributionCenter’s small parts storagelayout causes the order pickingprocess to contain excessivemotion and transportationwaste.
Kubota’s North American Distribution Center765,000 sq. ft. facility was established in September2015 in Edgerton, Kansas. The NADC serves as thecentral supplier for other Kubota branchwarehouses. The company is striving to continuallyimprove their lines per hour shipped and setsmonthly baselines to meet goals.

DATA
The company provided our team with zone maps,bin layout & dimensions, individual materialdataset, ABC & cycle count codes, bin reports. Binreports consist of the material descriptions, bintype, bin numbers, storage section codes, andpicking zones.
Shelves were pushed together to increase storagecapabilities and decrease aisle space.
Within the new layout, the configuration from rightto left is organized in a manner so from high moving ‘A’to dead ‘D’ parts. Due to the limited quantity of SP3bins, those were only allocated to hold the fast andmedium moving materials. Additionally, SP3’s were keptin their original shelving as their custom-made to theirsize.
Bin Numbers were renamed to accommodate thenew layout which includes modifying the aisle & shelfcodes. Due to the corrugated cardboard sheets, frontand rear bins were specified with either an ‘F’ or ‘R’respectively at the end of the new bin number.
. After examining the process flow, the team came to the conclusion that thepicking process was contributing the most waste to the system. In order toobtain a clearer idea of a Kubota Warehouse, our team took a tour of theKubota Central Warehouse in Fort Worth, Texas .
Figure 1: Pareto Detailing New ABC Codes
The Pareto examines the average line orders per stock item. A = 80% of Lines & 15% of StockB = 15% of Lines & 18.7% of StockC = 5% of Lines & 24.8% of StockD = 0% of Lines & 41.5% of StockFrom analyzing the zone maps and the Pareto Diagram, we developed two alternatives for potential layouts.
• X bar bar = Avg of Daily Averages, 27 lines/ hr• Set C_pk equal to 1, use standard deviation
from study• Find LSL and USL to determine where the
process needs to lie in order to be in control and meet goals.
• If USL is often surpassed, than expectations can be set higher
• If LSL is not often not met, process needs to be reevaluated
PROCESS CAPABILITY
Figure 2: C_pk Chart
Our team developed a new facility floor layout of the small bin section of NADC. Bin slot and bin locations were also redefined according to new product performance metrics (new ABC codes).
With this new design, we hope to increase lines per hour picked leading to a reduced lead times. The improvement aims to maintain customer satisfaction while reducing energy wasted by excessive motion and transportation of pickers.
UPS Worker EfficiencyTravis Mayes, Yousif Abushaaban, Isaac Hicks, Alan
RamirezIE 4350: Senior Capstone
The Capstone team was tasked with improving worker efficiency using the DMAIC methodology.
After gathering and analyzing data, we concluded changes need to
occur in the process map, layout, and lineup.
The process we are working with is workers loading
packages after sorting ontotrucks. The workers have
individual PPH (packages per hour) goals that are not being met. Data analyzed has been given to us by UPS. And the goal is to improve worker
efficiency.
Define:In order to improve worker efficiency, we need to
optimize methods and procedures
Measure:
Analyze:
Improve:
Control:
We proposed three separate implementations. The layout change was
not implemented in time for any measurements to be taken. The daily lineup improvements increased the
overall building PPH. After deleting waste in the flow chart and recommending it to
UPS we can assume that this would increase PPH as well.

ANCILLARY EQUIPMENT FACILITY DESIGN – DOLLUMUR XPE Michael James Shumate, Abdulhadi Jamil Syed, Luis Adolfo Torres Martinez,
Garrett Michael Jamieson, Haidang Vo NguyenIE 4350 CAPSTONE DESIGN – SPRING 2017
Setting up an entire new facilityrequires much more than procuringprimary equipment and plugging it in.Secondary equipment such aschillers, cooling towers, silos, andmore must be sourced, procured, andplaced on-site. This project includesthe sourcing and procurement of a100,000 pound outdoor silo and theoptimal placement of the remainingancillary equipment.
ABSTRACT
Dollamur Sport Surfaces, based inFort Worth, TX, procures their top rawmaterial, foam, from California andIllinois in order to manufacturewrestling mats. Freight for thismaterial alone costs more than$800,000 annually. A new facility wasplanned to convert Low DensityPolyethylene (LDPE) resin pellets tofoam. This will reduce this cost andallow Dollamur to better control thequality of the foam they use. A tradestudy was conducted to select a silofor raw material storage. FacilityPlanning and Design and EngineeringEconomics techniques were used toplace ancillary equipment optimally.
INTRODUCTION
METHODOLOGYThe trade study conducted onpossible silo showed that the mostfeasible choice of silo would be a K-Malt silo as it met all the requirementsset in the define phase. Pairwiseexchange was used to optimize theamount of piping running through thefacility. Figure 1 shows the amountfinal layout while table 3 and 4 showsthe end results of the the pairwise,resulting in a 29% reduction in pipingfrom the cooling tower and 17%reduction for the water tower pipingcompared to Dollamur’s original plan,shown in tables 3 and 4.
RESULTS
The recommended solutions for thenew facility layout enabled the overallproject to progress on schedule. Theproposed solutions for materialhandling and storage solutionsdecreased the operations costs. Also,the adjusted ancillary equipmentlayout resulted in significantreductions in installation costs.Overall, the new facility in addition tothe solutions implemented in thisproject will result in a forecasted totalsavings of $800,000 per year toDollamur Sport Surfaces.

FUTURE WORK
The Six Sigma DMAIC methodology was implemented to develop the solutions for the project. This methodology is composed of 5 phases: Define, Measure, Analyze, Improve, and Control.
DEFINE An overview process of the flow of LDPE through the facility, shown in Figure 1, was developed in order to define thematerial handling equipment this project will improve on. The storage silo and delivery procedure to the mixer will be further analyzed.In addition to the material handling procedures, this project will attempt to reduce installation costs for the remaining of the ancillaryequipment supporting the primary machines of the process.

MEASURE Table 2 shows each silo option with each metric value that was deemed important towards the requirements. All 3alternatives meet the requirements shown in Table 1. These measurements will then be scaled, analyzed, and compared to define themost valuable alternative for Dollamur XPE. The primary metrics of the pump are power, condition and cost. Also, manual materialhandling via forklift is an option that will be compared to the pump through net present value. Lastly, the initial proposed layout for thepiping lines of the ancillary equipment is shown in Figure 2.
Table 2. Silo alternatives and metrics
Table 1. Silo requirements
ANALYZE Weights were assigned to each of the silo criteria based on Dollamur’s priorities. This allowed for a Trade Study to bedeveloped to compare the 3 silo alternatives. The cost ratio factored in the difference the value of the silo and the logistics to install it,therefore all costs were grouped into a single metric. The results are shown on Table 3. For optimizing the piping throughout thefacility, pairwise exchange methodology is utilized to visualize relationships and mathematically determine a new iteration of positionsfor each of the ancillary equipment along the wall. Figure 3. shows the initial and final layout pairwise charts. Finally, a Present WorthAnalysis was performed using cost cash flows to compare the use of manual material (buy pump in 2 yrs.) or directly push the LDPEpellets through a pump (buy pump now). The results are shown in Table 4.
Table 3. Scoring charts for all silo alternatives
CONTROL It’s recommended that all procedures and processes be clearly documented and stored for future reference. It isexpected for Dollamur XPE to expand its manufacturing operations to a brand new facility in 2 years. The documentation will serve asa detailed guideline to better assist with silo vendor selection and produce the most cost effective design of pipeline connections forthe ancillary equipment.

Table 4. Present Worth Analysis Results
IMPROVE The ancillary equipment needs to be installed outside the facility to ensurecontinuous production of the XPE rolls. After many iterations of rearranging the ancillaryequipment to reduce amount of piping required using pairwise exchange, an overall decreaseof 23.6% of necessary piping for the facility’s water lines was noted, as compared to theproposed alternative. Figure 4 shows the best iteration of the facility layout design.

Cook Children’s Auditing SystemJenny Griffin, Stewart Lanie, Bryan
Pennington, Bushra Rohaizad, Abira SyedIE 4350 - Capstone Design
The Audiology Department at Cook Children’s Rehabilitation Services has an internal auditing process that is not accurately measuring the quality of patient charts. The senior design team will collaborate with stakeholders to increase the effectiveness of the auditing tool through the DMAIC methodology and implement corrective action.
Auditing patient charts is required by multiple entities, including the internal compliance department and external accreditors. The tool used for auditing has not been revised for several years. Many indicators have since become unnecessary and redundant. After analyzing the process, the overall tool was found to be only 24.1% effective for measuring chart quality. The objective of this project is to increase effectiveness to 100% by redesigning the auditing tool and implementing a standard process that will allow audiologists to take responsibility or the quality of patient charts.
Overall:Effectiveness Level: ~80%Average Cycle Time (with 15% PFD): 2.27 minutesStandard Deviation: 0.65 minutesTotal Improvement:Effectiveness Level: +75.9%Cycle Time: +38.7%Standard Deviation: +26.8%
The new auditing tool allows leadership a detailed and accurate overview of the quality of patient charts within their department. Previously deemed busy work required by accreditors, the tool now allows Cook Children’s to keep the whole department informed of their quality status, and to begin conducting corrective action as soon as possible.
