Abstract
All building materials such as brick, cement, paint, lime, steel, glass, etc. of various brands with small variation in their specifications and cost are available in the markets of construction. It becomes very difficult for contractors, engineers, and owners to make right choice of materials logically to maintain good quality and minimum cost of the work. Improper choice may result in either bad quality or higher cost. Multiple Attribute Decision Making Methods are very helpful in selection of any material. These methods have been used largely in various fields of engineering for deciding best of available options. This paper presents an overview of Simple Additive Weighting Method (SAW), Weighted Product Method (WPM) and Analytical Hierarchy Process (AHP) methods which can be simply and successfully used for selection of bricks.
Highlights
All building materials such as brick, cement, paint, lime, steel, glass, etc. of various brands with small variation in their specifications and cost are available in the markets of construction
Steel, stone, brick, glass, wood, tiles and many more materials are required for all types of construction works and all these materials of many verities are available with small variation in their attributes
The literature related to MADM does not show any application of these methods for the selection of materials used in the field of civil construction
Summary
A large variety of materials is present in the market of civil engineering, mechanical engineering, irrigation, medical etc. with different advantages and characteristics of each material. Selection of required beneficial material is difficult and challenging for a selector because attributes of available alternatives are found conflicting doe to day-byday emerging new technologies in field of manufacturing. It becomes multiple decision making problem when requires selection of material from more than two material with more than two attributes. Selection of best material for use in construction or manufacturing is a problem because selection criteria seem very close or conflicting. It needs some easy, scientific, and logical approaches which ease the selection procedure of any material that will be optimal for superior and economical construction. The assigned values of attributes are for demonstration purpose only
