Summary
This study introduces a hybrid hierarchical fuzzy multiple-criteria group decision making (HH-FMCGDM) model to rank brick manufacturing technologies. The model addresses economic and environmental concerns for cleaner production in the brick industry.
Area of Science:
- Industrial Engineering
- Environmental Science
- Decision Science
Background:
- Brick manufacturing faces challenges balancing economic performance with environmental concerns like air pollution and energy consumption.
- There is a growing need for sustainable and clean production methods in the brick industry.
- Existing decision-making models may not adequately address the multi-faceted criteria involved in selecting manufacturing technologies.
Purpose of the Study:
- To propose a novel hybrid hierarchical fuzzy multiple-criteria group decision making (HH-FMCGDM) model.
- To evaluate and rank alternative technologies for brick manufacturing based on economic, environmental, market, and technical criteria.
- To provide a robust decision-support tool for the brick industry to adopt cleaner production technologies.
Main Methods:
- Utilized a modified fuzzy analytic hierarchy process (MFAHP) to determine criteria weights.
- Developed a new method for assigning weight factors to decision-makers (DMs).
- Employed a fuzzy extended TOPSIS method for evaluating technology alternatives and a final aggregation approach to prevent data loss.
Main Results:
- The proposed HH-FMCGDM model effectively evaluated and ranked alternative brick manufacturing technologies.
- A real-life case study demonstrated the practical applicability and efficiency of the model.
- Sensitivity analysis confirmed the robustness and reliability of the obtained results.
Conclusions:
- The HH-FMCGDM model offers a comprehensive framework for selecting sustainable technologies in the brick industry.
- The approach helps decision-makers navigate complex trade-offs between economic and environmental factors.
- Managerial insights are provided to enhance the practical implementation of the model in real-world scenarios.

Bricks, a fundamental building material, are crafted from fired clay and exhibit a range of shapes, sizes, and colors. The production process starts with extracting local clay or shale, which is then crushed, ground, and screened for a fine texture. The refined material is blended with water, creating a pliable mixture that can be formed into bricks using one of three processes: soft mud, dry press, or stiff mud methods.

Brick sizing plays a crucial role in construction, influencing both the aesthetics and structural integrity of buildings. Bricks are defined by three dimensions: width, thickness, and length. They are commonly designed to fit modular measurements, typically in multiples of 4 inches or 8 inches in width, to facilitate uniform construction and compatibility with other building materials.

Bricks, a fundamental component of construction, are categorized based on their application and structural characteristics into several types. These include facing bricks, building bricks, hollow bricks, paving bricks, and firebricks. Facing bricks, also referred to as face bricks, are primarily used for both structural support and visual appeal, making their appearance a crucial aspect. In contrast, building bricks are typically used in concealed sections of a structure, such as behind the...

Brick masonry uses bricks as the building blocks and involves building walls from individual bricks laid in mortar. The basic building block of brick masonry is the wythe, a vertical layer of bricks with a thickness of one brick. Within a wythe, bricks can be laid in various courses or patterns, with the most common being the stretcher course, where bricks are laid with their long edge horizontal and face parallel to the wall.

1.6K
Reinforced brick masonry is an advanced construction technique that enhances the structural integrity of brick walls by incorporating steel reinforcements. These reinforcements are either placed within the hollow cores of bricks or sandwiched between two layers of masonry, known as wythes, and are then secured in place with grout. Grout is a fluid mixture composed of Portland cement, aggregate, and water, providing the necessary bonding agent for the steel and brick.
