What’s Inside: Some of DSI’s services to consider for your facility improvement projects:
Develop a “Strategic Alliance” Support Team for GMVO Paint Engineering Group’s procurement of a new paint shop. Team responsibilities included program administration, scheduling activities, financial control, document control, program safety support and training coordination.
GMVO Paint Engineering Group planned to procure a new paint shop facility, including all building and process requirements, from a single full-service contractor, rather than using multiple vendors for engineering, site construction, building construction, equipment installation, etc. The initial screening of contractors for capability of performance was the responsibility of GMVO Paint Engineering.
GMVO Paint Engineering needed a knowledgeable engineering/construction resource during the team engineering, site construction and facility activation stages.
“Bottom Line” Results
A Design Systems “Strategic Alliance” Support Team Concept was developed for the new GMVO Paint Shop that permitted the client flexibility of resource management without incurring additional fixed program costs. The concept included:
Engineering resources provided by the OSI team working parallel engineering studies with the full-service contractor engineering team. These parallel studies permitted the client to examine numerous alternatives offline without impacting the primary scheduling timeframe.
Alternate layout configurations being developed by the OSI Team based on site topography. This effort resulted in the client being able to reduce site preparation by approximately 30,000 cubic yards of fill material and 1400 lineal feet of retaining wall.
The DSI Team was configured to provide both full time and part time personnel as required to complete engineering and construction tasks in a timely manner and at minimal cost. The team consisted of five permanent members: Program Administrator, Administrative Assistant, Scheduler, Financial Controller and Document Controller. Six part time members were assigned to Miscellaneous Paint Process, MSQ Document Control, Electrical Controls, Contract Cost Management, Information Systems and Administrative Launch Assistance.
Evaluate and prove the systems’ ability to meet throughput objectives of 90 JPH “gross” and 77 JPH “average yield.”
Identify any deficiencies (bottlenecks) in cell flow as well as potential improvements to the cell design.
Define the effects of downtime, part shortages and operator efficiency.
A base model was developed for each of the subassembly cells under study. The base model simulation was run without the effects of downtime to verify that objective #1 was achieved and that input parameters were correct. Based on a random approach, downtime effects were applied to the model, and changes in the system behavior were recorded. This allowed the identification of system bottlenecks from statistical data. “What-if” scenarios were then performed on the simulation model to determine how the effects of downtime, material shortages and operator overcycles can be offset, thereby improving throughput.
“Bottom Line” Results
System Throughput: 78.5 JPH Base model Downtime Applied: 73.9 JPH Early and Late Breaks: 64.9 JPH Part Shortages On: 59.3 JPH Quality Issues On: 47.4 JPH
Station 13 identified as the system bottleneck. Part 14957 shortage significantly affected throughput.
Eliminating material shortages associated with part 14957 –> resulted in 52.1 JPH
Replacing Station 13 fixed conveyor with an accumulating conveyor –> resulted in 52.8 JPH
Improving Station 13 and Robot 11 cycle time to 40 sec –> resulted in 59.5 JPH
Eliminating early and late breaks –> resulted In (;1.4 JPH
Eliminating quality issue problems and resulting delays –> resulted in 84.2 JPH
Analyze the system and identify potential bottlenecks.
Evaluate the systems’ throughput at 100% capacity, with allowances for probable unscheduled downtime.
Evaluate “what-if” scenarios to improve system performance to a gross of 115 JPH.
Floor Pan Build System consisting of material handling and shuttle robots, welding robots, operators, turntable stations, and part sub-assemblies.
A baseline simulation model was developed reflecting the current operating conditions of the Floor Pan Build System. An analysis verified that the system’s operationallogic and cycle times could support the measured gross rate, taking into consideration process interaction, but without the effects of downtime. A net rate analysis was performed employing downtime data derived from actual observations. The data was analyzed, filtered and incorporated into the model when evaluating the impact of downtime on the system. Experimentation with respect to cycle time reductions was performed with the objective of achieving a target gross throughput of 115 JPH
“Bottom Line” Results
Gross Throughput –> 99.6 JPH Net Throughput –> 85.0 JPH
AFTER CYCLE TIME CHANGES:
Gross Throughput –> 114.6 JPH Net Throughput –> 97.5 JPH
Recommendations on ways to reduce cycle times in “arious al8Bs went offered, and included in the final report. For example, regstrling shuttle robots 10 and 19, the suggestion was made to eliminate the shuttle robots’ staging movements, thus eliminating redundant parts handling and reducing cycle times.
Like all USPS processing plants, a Bulk Mail Center (BMC) must use its resources wisely to meet the challenges of a changing mail processing environment.
Presently, package piece count is increasing 20 to 70% annually, prompting the BMCs to request installation of a Large Package Sorting System (LPSS). Without these systems, package volume will overwhelm BMCs in the near future, causing a degradation in service and higher costs due to an increase in manual processing.
The LPSS operates within BMCs and other USPS mail processing facilities to sort large parcels. Systems include a sorter and equipment to deliver and take away product from the sorter. The configuration of the system is site-specific depending on the space availability, package count, and number of distributions required.
These are the important points relative to the LPSS project.
Flexible Model for Evaluating LPSS Systems
The simulation was constructed with distinct modules, such as singulator, scanner, etc., so that different configurations could be easily modeled.
If different configurations are modeled, floor space requirements may be more accurately quantified after determining the effectiveness of the new system.
Package Sort Plans
The simulation model was tested using one sort plan. To optimize the number of runouts, changes must be made to the sort plan and the staffing of the runouts. Alternatives include:
Combining low volume runouts and having multiple pallets at one runout.
Splitting up high volume runouts to ease workload and minimize “full” conditions.
Using multiple operators at single high volume runouts.
The highest impacting deficiency in the LPSS system today is the sweep operation at the end of the runouts.
The uneven distribution of packages to these runouts decreases sweeper utilization and increases packages sent to the mis-sent runout, which is less efficient than the regular runouts. Optimizing the sort scheme will correct a large part of this problem.

System 3: Palletized order sortation using semiautomated bridge cranes.
“Bottom Line” Results
System can achieve 5100 rolls per day requirement Detennined optimum dispatch locations for empty AEM vehicles. Developed dispatch algorithm for empty vehicle selection of rewinder pick-up location. Developed AEM path flow logic to minimize vehicle flow restrictions through the following methods:
AEM track zoning
Pick-up/Drop-off decision logic
Determined minimum vehicle requirements of 12 for system ‘1 and 15 for system 12. Vehicle costs were $80,000 and $30,000 for systems ‘1 and 12, respectively.

Design Systems, Inc. proudly introduces an additional offering to its growing list of Conveyor Health Assessment services. The tension of the chain can be measured through the length of the conveyor with a Strain Gauge Link.
Strain Gauge Link Benefits:
Maximum tension in chain and location of the tension
Compare real tension data to theoretical Chain Pull results to avoid adding unnecessary drives
Chain Pull at each drive for the current load condition
Rolling friction of chain to verify lubrication effectiveness
Air pressure needed at take-up to give minimum system tension
Pulsing of chain tension from engagement with the drive’s cat chain
Link can be shipped, installed and removed by plant personnel, then returned for data processing, to limit engineering time in the field
Results presented on a graph of tension vs length of conveyor
Temperature limit is 170°F due to battery limitations. Higher temperature applications are possible with the data logger in an insulated enclosure attached to the chain.
Other Possible Configurations:
A Strain Gauge Link will show the difference in tension before and after it passes a drive. A drive monitor sensor will show the Chain Pull at the drive for varying load conditions that occur during the day. Results are presented on a graph of Chain Pull vs. time to determine maximum pull of the drive.
Carrier Rolling Friction
A tension sensor can be used to measure individual carrier pull by temporarily attaching to the preceding carrier. This will give actual rolling friction for the carrier wheels to use in Chain Pull analysis, instead of a theoretical value.
Strain Gauges can also be added to the framework of a conveyor turn that is at the lowest tension in the system. When the loads vary, the take-up air pressure can be adjusted with feedback from the gauges to keep chain at the lowest tension which reduces wear.
