Ch. 5: Manufacturing Systems

Material Handling

• Art and science associated with the movement, storage, control and protection of goods and materials

• Right amount of material, right place, right position, sequence, etc

Three Views on the Scope of Material Handling

1. Conventional: Moving from one to another

   1. Usually within the same facility

2. Contemporary: Expands to the integrated and overall movement of materials

3. Progressive: Total system view, all material handling system from all suppliers within a facility and distribution of finished goods to customer

Six Step Engineering Design Process

1. Define objective and scope

2. Analyze the requirements for material handling system

3. Generate alts

4. Eval. Design

5. Select preferred

6. Implement and review

Theoretical Ideal System

Perfect system having zero cost, perfect quality, safety hazards and no wasted space

Ultimate Ideal System

Achievable in the future using the technology not available today

Technologically Workable Ideal System

Tech. Is available but very high cost to install

Recommended System

Cost-effective system that can be installed successfully now

OSTI

• O: Operation

• T: Transport

• S: Storage

• I: Inspection

Unit Load

• Picked up and moved between two locations as a single mass

• : One pallet of cartons

Advantages of Pooling System

• Min movement of empty pallets, increasing utilization

• No need for allocating extra space to store pallets

• Operator own the containers and pallets, responsible for maintaining them, hence better quality

Rough Cut

• Uses standard data and rules of thumb, we can get reasonable accurate estimates by using the unit cost of pallets

• Can vary

OSHA

• Occupational Safety and Health Administration

• Interface between workforce and equipment

• Can compromise width of aisles for type of vehicles use

  • : Forklifts
