•
0 likes•221 views
This document discusses how 3D printing spare parts on-site can significantly impact operations in remote locations like Mali. A case study was conducted analyzing data from the Royal Netherlands Army for 3000 spare parts across three systems. 100 parts were assessed for printability, and 14 were deemed printable with the current printer. Modeling estimated on-site printing could reduce base stock levels by 74% and downtime by 92% for the analyzed parts in Mali. The positive impacts of on-site printing are expected to grow as the technology improves and more parts can be printed.

Troy Schlegel- Accomplishments
This document provides a summary of Troy Schlegel's accomplishments as an Electronics Manufacturing Engineering Manager. It lists numerous projects and initiatives implemented that resulted in savings, increased production and efficiency. Key achievements include implementing 5S, component storage and retrieval systems, frameless stencils, SMT processes, CAD/CAM programming, production tracking software, time management systems, automated component tinning, and color chart methods. Many projects reduced costs and cycle times while improving productivity, production, and on-time delivery.
170614 MSc Project Thales (Michel Reimert)
The document outlines a research project investigating how 3D printing can decrease life cycle costs of one-off parts for Thales Hengelo. It presents the research context, problem, goal, and question. The solution approach involves life cycle cost analysis and a stochastic dynamic programming model to determine the optimal time to use 3D printing. Results from model evaluations, two case studies on radar parts, and future case studies are presented. The research concludes that 3D printing can currently decrease costs in the after-sales phase and future reductions in 3D printing costs may lead to higher savings. Recommendations include reconsidering inventory for parts causing downtime and further research on 3D printing applications and impacts.
170614 Progress Update WP3 (Nils Knofius)
This document discusses numerical experiments and a case study on dual sourcing spare parts using both conventional manufacturing (CM) and additive manufacturing (AM). The key findings are:
1) Dual sourcing can provide cost savings over single sourcing from CM or AM alone, especially when backorder or holding costs are high. Even with higher AM part costs or failure rates, dual sourcing is beneficial.
2) With dual sourcing, the AM source is typically used for emergency resupply due to its higher costs. The proportion fulfilled by AM decreases as its costs or failure rates increase.
3) Applying dual sourcing to a hinge bracket case study showed limited savings due to high AM part certification costs
Overstated role of_capital
The document discusses how manufacturing companies would spend capital if it were available at low interest rates. It lists potential investments such as automation equipment, computer systems, and newer models of existing machines. It also compares assembly plant characteristics and automation levels across different global regions. Some key points made include that highly automated plants require more indirect workers and have lower yields due to breakdowns. It also discusses the benefits of retrofitting older machines with preventative maintenance versus installing all new equipment.
computer aided process planning
Computer Aided Process Planning (CAPP) is used to develop manufacturing plans based on cost, time, availability and other factors. CAPP provides instructions for producing designed parts and links CAD to CAM. There are two main types of CAPP systems: variant systems use standard plans while generative systems automatically generate plans. CAPP determines the instructions and parameters needed to manufacture a part.
170614 Progress Update WP2 (Bram Westerweel)
The document discusses on-site additive manufacturing of spare parts. It presents a model for analyzing the costs and benefits of using on-site 3D printing of spare parts compared to regular replenishments and expediting. The model finds that on-site 3D printing can lower operational costs by decreasing optimal inventory levels and replacing expediting as the preferred emergency supply method late in the replenishment cycle. A case study on printing a carter-plug part for military vehicles found potential savings of over 10%. However, further research is still needed to determine if the investment in on-site 3D printing capabilities outweighs the costs and to establish best practices for temporary versus failure-based use of 3D printed parts.
Automated Measurement System Analysis (AMSA)
An automated measurement system called AMSA is proposed to digitize TST's inspection process. Currently, inspectors manually record measurements on paper, which are not analyzed to improve processes. AMSA would use wireless data loggers, transmitters, receivers and a main computer database to electronically capture inspection data in real-time. This would save on paper usage and data entry costs while enabling real-time monitoring and analysis of measurements to quickly address issues. The estimated investment cost is 408,320 Baht with a potential payback period of 3.17 years given projected annual cost savings of 129,000 Baht from reduced paper and labor. Appendices provide supplier contact information and a list of tools that could be connected to

This document discusses activity-based costing (ABC), which allocates overhead costs based on activities that drive costs rather than volume. It provides examples of unit, batch, product, and facility-level costs and cost drivers. The key advantage of ABC is that it eliminates cross-subsidies between high and low volume products seen in traditional volume-based costing. While initially developed for manufacturing, ABC has also been adopted by service industries.

Optimization and Balance deployment for MPS
This document discusses optimization and balanced deployment strategies for managed print services. It outlines three pillars of MPS: manage devices effectively, optimize devices for efficiencies, and develop print policies and workflows. MPS with balanced deployment can typically save 25-50% on costs by streamlining processes, boosting productivity, and optimally deploying devices. The process involves an assessment of current device usage and costs, followed by recommendations to realign the print environment for greater efficiencies and savings. Considerations include addressing over-capitalization, refreshing old devices, controlling color printing costs, and balancing deployment against employee needs.
Finite capacity planning and scheduling for manufacturing: Odoo frePPLe conn...
These slides were presented at the odoo opendays 2014.
In a manufacturing plant creating feasible material plans, capacity plans and workforce schedules quickly gets complex - and reaches beyond the capabilities of MRP or excel spreadsheets.
FrePPLe is a leading open source finite capacity planning and scheduling application that provides advanced algorithms for this purpose.
In this session we'll demonstrate the 2-way integration between frePPLe and Odoo, and focus on the value the combination Odoo+frePPLe brings to manufacturing companies.
Work
Work measurement is a technique used to establish the time required for a worker to complete a specified job at a defined performance level. There are four basic work measurement techniques: time study, work sampling, predetermined motion time data systems, and synthesis of standard data. A manufacturing plant implemented work measurement using UMT PLUS software to identify non-value added activities and improve productivity by doubling production while optimizing resource utilization.
ATCO Engineering - Process Evaluation
This document evaluates current systems and processes at ATCO Engineering & Contracting's engineering division and provides recommendations. It finds that key processes like estimation, planning, procurement, payroll, inventory management, and job costing are mostly done manually with redundant data entry, lacking integration between functions. The recommendations include implementing an ERP system to integrate processes, automate data entry and workflows, and capture more project data for analysis to improve project management. A phased implementation plan is proposed starting with shorter term wins in procurement, budgeting, and payroll, followed by longer term changes to estimation and planning.
Unit 3-IE6605 & PRODUCTION PLANNING AND CONTROL
Product planning identifies market requirements to define a product's features. It serves as the basis for pricing, distribution, and promotion decisions. Value analysis aims to increase value, defined as function over cost, by improving function or reducing cost. Lack of product planning can lead to unsatisfied customers, quality issues, and loss of brand name. Process planning involves routing, scheduling, dispatching, and follow up based on product information, processes, capacity, orders, due dates, and resources. Economic batch quantity determines the optimal batch size to minimize average costs by balancing setup costs and inventory holding costs.
KPI Focus
KPIs are formulas that collect evidence to indicate if management is improving or worsening performance over time. An example KPI for elevator management could be the "Average Wait" per 1000 requests, which measures the total wait time divided by 1000 requests on a weekly basis. This would indicate if changes are making people wait less or more on average. Other possible elevator KPIs include the average cleaning cost per month, elevator system availability monthly, or watts used per trip daily. To create a good KPI, you measure a key concern or critical success factor, compare it to a perfect standard, and review the data regularly to track progress.
Reclamation Information System
To support the Environmental Protection and Enhancement Act (EPEA) The government of Alberta through the ministry of Environment and Parks (AEP) collaborated with industry in 2010 to build the Reclamation Information System (RIS). To further the RIS system’s strength in delivering high quality spatial data through the application process, AEP again collaborated in 2017 to complete updates and guide the implementation of a web-based submission interface. The submission tool utilizes many technologies and our presentation will focus on the use of FME Server.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.
Diese Themen werden behandelt
- Reduzierung der Lizenzkosten durch Auffinden und Beheben von Fehlkonfigurationen und überflüssigen Konten

- 10. On-site printing results (3) 26-9-2018SINTAS AM workshop 10
- 11. Model building Supply of spare parts • Scheduled replenishment to the base every 𝑳 periods • On-site printing as an option for backorders that occur in between replenishments 26-9-2018SINTAS AM workshop 11
- 12. Model building Spare parts characteristics and demand • Replenishment and printing has a zero-period lead time • Printed parts have a higher probability of failure 𝒑 𝒑 > 𝒑 𝒓 • Unit ordering costs 𝒄 𝒓 and 𝒄 𝒑 • Number of systems = 𝑵 We assume that printed parts are removed and disposed of at the end of each order cycle 26-9-2018SINTAS AM workshop 12
- 13. Simple optimal policy structure 26-9-2018SINTAS AM workshop 13
- 14. Model application The RNLA provides us with data on ~3000 spare parts for three of its systems 26-9-2018SINTAS AM workshop 14
- 15. Where to start? Not all parts can be printed and technical assessments are labor intensive • Multiple criteria determine printing potential. We use a scoring framework adapted from Knofius et al. (2016) • 100 spare parts are assessed by the RNLA’s AM expert • 14 parts can be printed with the current printer 26-9-2018SINTAS AM workshop 15
- 16. Parameterization based on Mali Printing costs are determined based on volume 𝒗, printing speed 𝒔, raw material cost 𝒄 𝒎, and depreciation cost per hour 𝒄 𝒅 Printed parts are estimated to fail approximately 10 times faster than regular parts 𝒑 𝒑 = 𝟏𝟎𝒑 𝒓 Installed base size = [𝟔, 𝟖, 𝟒𝟐] Holding costs 𝒉 = 𝒄 𝒓/𝟑𝟔𝟓 Weekly replenishment to the main operating base 𝑳 = 𝟕 𝒅𝒂𝒚𝒔 26-9-2018SINTAS AM workshop 16
- 17. Application results for Mali 26-9-2018SINTAS AM workshop 17
- 18. Application results for Mali 26-9-2018SINTAS AM workshop 18
- 19. Application results for Mali • Base stock levels decrease by 74% and downtime by 92% 26-9-2018SINTAS AM workshop 19
- 20. Application results for Mali • Base stock levels decrease by 74% and downtime by 92% • We find a -0.52 correlation coefficient between the spare parts rank and annual savings 26-9-2018SINTAS AM workshop 20
- 21. The impact of printing in Mali To what extent are these parts representative of the entire set? • Technical feasibility is not a criterion of the part ranking method • This implies that 10-20% of parts can be printed • And this number will grow as technology develops We only considered 3 systems, but there are many more! 26-9-2018SINTAS AM workshop 21
- 22. Extension: Operations closer to home Sometimes parts can be expedited overnight at a premium cost in case of a shortage • Denote unit expediting costs by 𝒄 𝒆 > 𝒄 𝒓 and 𝒄 𝒆 > 𝒄 𝒑 Illustrating a new optimal policy structure 26-9-2018SINTAS AM workshop 22
- 23. Extension: Operations closer to home Suppose that 𝒄 𝒆 = 𝟒𝒄 𝒓 (Recall that printing saves 58% by itself) • Expediting saves 9.8% as a stand-alone option • Combining expediting and printing saves 58.7% On-site printing will also impact operations closer to the Netherlands and its allies 26-9-2018SINTAS AM workshop 23
- 24. Conclusions On-site AM will significantly affect the RNLA’s operations in remote locations by: • Decreasing required storage space via reduced base-stock levels • Increased asset availability by a cheap temporary solution to inventory shortages Benefits are attained even if printed parts have much worse characteristics than regular parts! On-site AM can be applied to a substantial subset of parts 26-9-2018SINTAS AM workshop 24
- 25. Broader implications 26-9-2018SINTAS AM workshop 25
