1. Straight Flow Line: The shortest distance between two given points is the straight line. This line provides a guideline for the path to follow.
2. Standardization of Methods: The line method of picking carrying and setting down of material varies. This does not call of an analysis like micro motion analysis but calls for forming a basis for MH in the minimum length with the available equipment. When the method is standardized the time could be fixed and wastage in time labor and equipment could be eliminated.
3. Short Irregular Moves : some MH operations are not repetitive in nature. In such cases deployment of equipment may be costlier than manpower. If the load capacity does not exceed the manpower it is economical to use manual labor for short and irregular moves.
4. Propositioning of Materials : Wherever practicable materials ( viz. Containers after determination of unit loads) should be moved on a horizontal plane. When loading and unloading excessive work can be reduce if the work layout is properly planned.
5. Loading and Unloading : Since a major portion of MH activity line in loading and unloading this function must be given a great deal of attention. Wherever economical loading and unloading should be done by mechanical devices such as industrial trucks cranes conveyors etc. When this principle is followed not only is the possibility of loss and damages reduce but accident hazards are also reduced and safety and protection are increased.
A large number of pickup and delivery points will increase loading and unloading requirements affecting manpower and equipment. Therefore several pickup points should be combined into one central point. Further by segregating materials at source or destination will eliminate double handling of materials.
