WHEN TO DESIGN A MATERIAL HANDLING SYSTEM?
The need to design a material handling system arises when:
SCOPE OF MATERIAL HANDLING
The scope of material handling activity in any industry depends on the type and size of industry, the product manufactured, the value of the product, the value of the activity being performed, and the relative importance of material handling activity to the other activities. However, it should be emphasized that a sizable portion of total material handling activity is not in manufacturing but in the fields of distribution, service industries, agriculture, and construction. It is very important that both the beginning student and material-handling engineer be aware of the material handling applications in the following areas:
PRINCIPLES OF MATERIAL HANDLING
The College-Industry Council on Material Handling Education (CICMHE), sponsored by Material Handling Institute Inc., adopted 20 principles of material handling.
These principles (Table 1.) represent the experience of designers who have been working in the design and operations of handling systems. These principles serve as rough guides or rules of thumb for material handling system design. The designers of material handling systems are usually advised to follow the following principles. However, in some cases they might not be able to apply them to the fullest extent because of factors such as the limitation on capital, physical characteristics of the building, and capability of the equipment.

FACTORS FOR CONSIDERATION IN MATERIAL HANDLING SYSTEM DESIGN
The material handling system design process is iterative. The analyzer has to go back and forth between the different steps until a satisfactory design has been obtained and can be implemented. The major factors for consideration in material handling system design are:
