  • 3. Industrial and Systems Engineering Senior Design Projects Project 1: Inventory Management System for Elgin Industries Company: Elgin Industries Students: Justin Koda James Lezon Jason Schafer Time: 10:00 – 10:20 a.m. Location: Room 241 Faculty Advisor: Dr. Ghrayeb Abstract: The main goal of this project is to formulate a model designed to reduce the current inventory levels for Elgin Industries. Elgin Industries has been a major producer and distributor of automotive engine and chassis parts for many years. There are several factors which will need to be considered to find the best method. First of all, we need to determine which products are mainly responsible for the excessive stock level. Collectively, the company is responsible for approximately 22,000 SKUs. However, only a small percentage of these SKUs account for the majority of stock. Secondly, the lead time for each of the products is unknown. Lead times for each product will be essential in determining an order level. However, Elgin Industries has a very complex order and receiving system where single orders are received in random quantities at several different times. To add to the lead time complexity, some products are kitted and require extensive analysis to calculate a time. Next, Elgin Industries’ clientele typically makes purchases on an as needed basis. This causes product demand to be very unpredictable. Many of the products are sold in large volumes with considerable variation from month to month. Next, certain conditions must be considered when developing the individual inventory models. Due to the company’s strong devotion to customer service, it is important that the percentage of stock outs is kept to a minimal level. However, this loss of goodwill must be weighed against the cost of storing a product in inventory. Also, there is the storage space factor which must be considered. Finally, due to the high volume of SKUs, the data must be arranged in a presentable and accessible manner so that it can be easily referenced. If the data is scattered, the findings will be difficult to implement. Therefore, the most practical way to present our findings would be a database table using software such as Microsoft Access. Only after all of these factors are considered can a valid inventory model be formulated. 1
  • 4. Industrial and Systems Engineering Senior Design Projects Project 2: Analysis and Time Study of Assembly Operation Company: Bergstrom Incorporated Students: Scott Hickey Marcin Kociolek Calvin Wong Nathan Woodson Time: 10:25-10:45 a.m. Location: Room 241 Faculty Advisors: Drs. Asoudegi, Moraga and Rahn Abstract: Bergstrom Incorporated is company that produces cab climate systems for many different types of trucks and off road machines. This project will examine the assembly of two different systems. The two lines will be observed to see what possible improvements can be made, followed by time studies to determine standard assembly times. Upon completion of these time studies, analysis of the throughput and line balancing will be done to increase efficiency. Process maps, value stream maps, and flow charts will all be included to see the process and the cost of each. Finally, a manual of steps taken to complete this project will be included for Bergstrom to continue on to other assembly lines as needed. It is believed that there is much inefficiency within these two lines, so great success is imminent. 2
  • 5. Industrial and Systems Engineering Senior Design Projects Project 3: Ideal Industries Kanban System Company: Ideal Industries Students: Colby Curtis Andrew Ellia Time: 10:50 – 11:10 a.m. Location: Room 241 Faculty Advisors: Dr. Ghrayeb and Moraga Abstract: The objective of this project is to design an inventory management system for Ideal Industries’ new Pulsar 60 press at their Sycamore production facility. The Pulsar 60 will be used to produce six brand new products, each of which will be subsequently conveyed “downstream” to Ideal’s DeKalb facility. Using the principles of JIT manufacturing, the project team will design a Kanban inventory management system that will reduce costs by virtually eliminating overproduction, excessive production resources, and excess inventory. The project team will be utilizing computer simulation to optimize the final parameters of the Kanban system. 3
  • 6. Industrial and Systems Engineering Senior Design Projects Project 4: Process Improvement for Motorola’s CCSI Sector Company: Motorola Students: Chris DeFalco Andy Wyrwal Time: Room 241 Location: 11:15 – 11:35 a.m. Faculty Advisors: Drs. Ghrayeb and Rahn Abstract: The objective of this project is to improve the overall process for Motorola’s CCSI sector. The first step would be a define stage implementing process mapping. The CCSI system, including the testing phase, would be the first target. This is crucial to help define the critical parameters and identify any waste that can be eliminated. This information is essential to any improvement that will be suggested. The mapping should then be widened to include the areas both upstream and downstream of CCSI in the supply chain. This will also yield key information for the critical parameters, and will give CCSI a better understanding of the aspects that they can control, as well as those they cannot. 3
  • 7. Industrial and Systems Engineering Senior Design Projects Project 5: Plant Layout Analysis and Redesign Company: SPX Fluid Power – Rockford Illinois Students: Stephen Lamb Cory Meyers Shannon Milligan Time: 11:40 – 12:00 Location: Room 241 Faculty Advisor: Dr. Ghrayeb Abstract: The SPX facility in Rockford has major layout flaws that require attention to improve operations. The factory is a composite of three other SPX companies that have been crammed together into one building which has led to a disjointed and inefficient layout. The goal of our project is to familiarize ourselves with the plant and perform analysis of material flow in order to create an updated and efficient design. We will achieve this goal through a series of analysis starting with a large amount of data collection. Last years highest sales by volume will determine which finished units will be studied on each of SPX’s 90 or so workstations. These units will be broken down into components whose routes will be tracked and mapped through the facility in order to illustrate material flow. This data will be converted into a layout via from/to analysis and the CORELAP algorithm. We will use this information to develop a new, optimal layout for SPX. Upon completion, we will perform an overall analysis of savings that will be produced by our redesign. The deliverables of the project will be presented to the company, hopefully to be implemented in the near future. 4

  • 15. Mechanical Engineering Senior Design Projects Project 1: TTX Torque Measuring Bolster Company: TTX Students: Gleb Maksimov Corine McNamara Time: 9:05 – 9:25 a.m. Location: 101 Faculty Advisor: Dr. Fallahi Project Objective: To modify an existing bolster so it will be able to measure the torque, lateral and vertical loads on bow-liners. Project Summary: The main goal of this project is to model and design a bolster that is capable of measuring torque, lateral, and vertical loads. Currently bolsters are used on all TTX freight trains and it connects the two side frames of the car that hold the wheels and add support. On the car type of interest, a 125-ton articulated double stack care there is one truck, containing a bolster, two side frames, and a set of wheels in between a set of two cars. A bow-liner is inserted in the center bowl of the bolster. The articulated cares currently use plastic bow-liners that wear out quickly. In order to switch to metal bow-liners, which are used on various other trucks, the forces in the uncoated metal the coated metal and the plastic liners must be compared. In order to do this, an existing bolster was modified to hold a strain-gauged cylinder that is able to measure all the forces going throw the center bowl and the liners. A box was then signed and built to put the strength back into the cutout bolster. This design was drawn in AutoCAD and modeled in SolidWorks. Then extensive studies in Cosmos were performed to measure the bolsters ability to carry the necessary loads. The device will be tested in Pueblo Colorado at TTCI. The truck containing the modified bolster will also be equipped with existing instrument wheel sets to measure the forces in the wheels. The car will go through several tracks empty and loaded and the results form the three liners will be compared. In order to switch to the uncoated metal liners they prove to be safe by the railroad criteria. 12

  • 24. Engineering Technology Senior Design Projects Project 1: Steel Drum Company: NIU Students: Daniel J Brey Kyle F Shanley Adam R Theis Time: 9:30 – 9:50 a.m. Location: 311 Faculty Advisors: Dr. Mirman, Dr. Azad, Project Objective: - To create an electronic replica and/or substitute for a steel drum. - To be more affordable than current steel drums Project Summary: The technological sprawl of the 21st century demands availability of ethnic instruments to studio musicians and the public. Few islanders presently construct steel drums; making it a rare and expensive instrument to procure. Our project helps by providing one possible alternative. The goal of this project was to develop an electronic version of a musical steel drum. A system capable of producing MIDI (Musical Instrument Digital Interface) messages was developed to achieve this goal. MIDI is a system used to specify the actions of a synthesizer or other MIDI capable electronic device through digital messages sent to those devices. The synthesizer can be configured to replicate musical notes; for example the notes of a steel drum. The main parts of the electronic system include; 8 force sensing resistors, signal conditioning components, a microcontroller based sensor to MIDI interface, MIDI cables, and synthesizer. The signal conditioning consists of placing the FSR in a voltage divider that feeds a comparator. This allows denouncing and adjustable threshold. When struck, a force sensing resistor signal is sent through signal conditioning components to produce a logic level high pulse. The sensor signal is then sent to one channel of a controller capable of producing MIDI messages. The MIDI message is then sent to a synthesizer or other capable device to replicate the sound of a steel drum. The note is heard through speakers attached to the synthesizer. The system is equipped with 8 sensors and is thus capable of producing 8 discreet notes. These notes can be programmed but are not user programmable. Physically the project consists of a circular enclosure 4” high and about foot in diameter with a small tab for connectors. The sensors are mounted on the top like a steel drum is arranged and midi cables to connect to a synthesizer or an interface to a computer are provided. A Led on top indicates proper working condition. 21
  • 25. Engineering Technology Senior Design Projects Project 2: Compound Parabolic Concentrator for Crop Drying (Solar Crop Dryer) Company: Students: Brandon J Borgman Justin T Masters Stephen M Toth Time: 9:55 – 10:15 a.m. Location: 311 Faculty Advisor: Dr. Tatara Abstract: Our group has begun research on a sustainable crop drying solution. The scope of our research focuses on the feasibility and practicality of using Compound Parabolic Concentrator (CPC) technology to dry crops. We will test the effectiveness of the CPC to dry crops by building a prototype crop dryer with two key parameters. First, the machine will be completely mechanical and sustainable. This means that the CPC crop dryer can not depend on fuel or electricity to run. Second, the moist crop must enter into the machine, advance through the concentrated light, and exit with reduced moisture content. In the event that the prototype is a success, we have created advanced designs for a full scale CPC Crop Dryer based on the initial design of the prototype. This larger machine was designed to be easily assembled right out of the box, and is constructed out of durable, machine-able, affordable materials. Projective Objective: Determine the feasibility and practicality of using Compound Parabolic Concentrator (CPC) Technology to dry crops.

Donovan Joshua L Malmassari Doug K Meenan John Z White Time: 10:20 – 10:10:40 Location: 311 Faculty Advisor: Dr. Otieno Project Objective: The objective of the Basic Utility Vehicle is to design a low cost yet versatile all-terrain vehicle for third world countries. Project Summary: Our senior design project consists of the design and fabrication of a Basic Utility Vehicle (BUV). The vehicle cannot exceed 12 horsepower and must have a minimum payload capacity of 1100 pounds. The concept behind the BUV is to design a vehicle that is inexpensive, capable, and reliable for third world countries; our design is specified for Africa. The Institute for Affordable Transportation (IAT) has been sponsoring the Basic Utility Vehicle Competition in order to find better designs to improve transportation in third world countries. This vehicle will be entered in the annual BUV competition in Indianapolis on April 28 th . 23

Engineering Technology Senior Design Projects Project 4: Caterpillar Tire Assist Mechanism Company: Caterpillar Students: James P Holmstead Adam J Kearns Time: 10:45 – 10:05 a.m. Location: 311 Faculty Advisor: Dr. Mirman Abstract: We are building a tire manipulation mechanism to flip the tires from their sidewalls up onto their treads. The mechanism will utilize an overhead crane within Caterpillars facility. The station attendant will then be able to use the overhead crane to flip the mechanism, which is mounted to the floor with 3 pivot brackets. This will eliminate the need for a specialized forklift operator to be on call when the attendant needs the tires orientated, and this will also eliminate possibility of injury to the station attendant. 24
