Objectives of Material Handling

• Reduce Unit Material

Handling Cost

– Eliminate Unnecessary

Handling

–Handle Material in Batch

Lots

–Minimize Required

Handling Time

– Replace Handling

Equipment as

Appropriate

• Reduce Production

Time

–Minimize Delays of

Machine Operations

–Maintain Uniform,

Appropriate Movement

of Material

–Use Automatic

Processing When

Appropriate

– Coordinate All Material

Objectives of Material Handling

• Reduce Overhead

–Minimize Non-Productive Labor

–Prevent Damage to Materials

• Conserve Floor Space

– Avoid Excessive Stock Storage

–Move Materials in a Position to Save Space

– Use Equipment Requiring No Floor Space

Objectives of Material Handling

• Prevent Accidents

– Reduce Physical Load Required

– Insure Handling Equipment is Safe

• Improve Employee Morale

– Provide Proper Relationship Between Employee &

Work

Principles of Material Handling

There are 10 principles of material handling:

• Planning Principle

• Standardization

Principle

• Work Principle

• Ergonomic Principle

• Unit Load Principle

• Space Utilization

Principle

• System Principle

• Automation Principle

• Environmental Principle

• Life Cycle Cost Principle

Principles of Material Handling

Planning Principle

• A material handing plan

defines

– the material (what) and

– the moves (when and where);

together they define

– the method (how and who).

Standardization Principle

• Material handling methods,

equipment, controls and

software should be

standardized

• within the limits of

achieving overall

performance objectives and

• without sacrificing needed

flexibility , modularity and

throughput.

Principles of Material Handling

Work Principle

• Material handling work

should be minimized

– without sacrificing

productivity or

– the level of service required

of the operation.

Ergonomic Principle

• Human capabilities and

limitations must be

recognized and respected in

the design of material

handling tasks and

equipment to ensure safe

and effective operations.

Principles of Material Handling

Unit Load Principle

• A unit load is one that can be stored or moved as a single entity at one time, such as a pallet, container or tote, regardless of the number of individual items that make up the load.

• Smaller unit loads are consistent with manufacturing strategies that embrace operating objectives such as flexibility, continuous flow and just-in-time delivery.

Space Utilization Principle

• Cluttered and unorganized

spaces and blocked aisles

should be eliminated in

work areas.

• In storage areas, the

objective of maximizing

storage density must be

balanced against

accessibility and selectivity.

Principles of Material Handling

System Principle

• A system is a collection of interacting and/or interdependent entities that form a unified whole.

• Systems integration should encompass the entire supply chain including reverse logistics.

• It should include suppliers, manufacturers, distributors and customers.

Automation Principle

• Material handling operations

should be mechanized and/or

automated where feasible

– to improve operational

efficiency,

– increase responsiveness,

– improve consistency and

– predictability, decrease

operating costs and

– to eliminate repetitive or

potentially unsafe manual

labor.

Principles of Material Handling

Environmental Principle

• Environmental impact and

energy consumption should

be considered as criteria

when designing or selecting

alternative equipment and

material handling systems.

Life Cycle Cost Principle

• A thorough economic analysis should account for the entire life cycle of all material handling equipment and resulting systems.

• Life cycle costs include all cash flows that will occur between the time the first rupee is spent to plan or procure a new piece of equipment, or to put in place a new method, until that method and/or equipment is totally replaced.

• These may broadly be divided into the

following types:

– Fixed Path Equipments

– Semi-Fixed Path Equipments

– Variable Path Equipments

– Accessories

Material Handling Equipments

Fixed Path Material Handling

• Advantages:

–More economical if large volume of material

moved to same place

– One power supply to drive entire “belt” – more

economical

– Reduction in need for lot identification tags

– Can be used to pace the workers

• Disadvantages

– Less economical if material follows diverse paths

Semi Fixed Path Material Handling

Types

• Cranes

– Jib

– Bridge

– Gantry

• Tracks

–Monorail

– Industrial Rail

Advantage & Disadvantages:

• Advantage

– Can cover a wider area

• Disadvantage

– Still limited to area covered
