This document discusses group technology and cellular manufacturing. Group technology is a manufacturing philosophy that groups similar parts together to take advantage of their design and production similarities. Cellular manufacturing is an application of group technology where machines are organized into cells dedicated to producing part families. The key benefits are reduced setup times, inventory, and lead times while improving equipment utilization and throughput.

Cellular layout helps us in increasing the productivity with minimizing the cost.
It is the latest technique to minimize the cost and increase the profits without affecting the organization. The concept of LEAN management.
cells are dedicated to produce similar products or a family of parts.
A manufacture cell produces parts, one at a time, following the sequence of the machines and operations in a lean flow.
It is an application of Group Technology in Manufacturing
Facilities Layout is the method of allocating machines & equipments, various production process and other necessary services involved in transformation process of products with the available space of the factory so as to achieve the greatest possible output of high quality at the lowest possible costs of manufacturing.
Group technology is a manufacturing technique and philosophy to increase production efficiency by making use of the “underlying sameness” of component shape, dimensions, process route,

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Large manufacturing system can be decomposed into smaller subsystems of part families based
on similarities in
1. Design attributes and
2. Manufacturing features
5. IDENTIFYING PART FAMILIES
DESIGN ATTRIBUTES:

work flow and information, whether computer controlled or not)
23. EVALUATION OF CELL DESIGN DECISIONS
The evaluation of design decisions can be categorized as related to either
• The system structure
or
• The system operation.
24. EVALUATION OF CELL DESIGN DECISIONS
Typical considerations related to the system structure include:
• Equipment and tooling investment (low)
• Equipment relocation cost (low)
• Material-handling costs (low)
• Floor space requirements (low)

28. DIFFERENT BETWEEN GROUP TECHNOLOGY
AND CELLULAR MANUFACTURING
Group technology is manufacturing philosophy which similar parts are identified and group together to
take advantage of their similarities in design and production.
But, cellular manufacturing is organizing the production equipment into machine cells, where each cell
specializes in the production of a part family.
On the other word, cellular manufacturing is an application of GT in which dissimilar machines or
processes have been aggregated into cells, each of which dedicated to the production of a part,
product family, or limited group of families.
