Lesson 1: Positioning Flashcards
What are the signs of successful layout in plant layout? (9)
- Directed flow of patterns
- Predictable processing time
- Little WIP (Work In Progress) in the facility
- Open floors: allow communication and easy tracking of work and employees
- Bottleneck operations under control
- Work stations close together
- Orderly handling and storage of raw materials and finished products
- No extra handling or unnecessary handling of materials
- Can easily adapt to changing conditions
Examples of directed flow patterns (2)
- Straight line or other smooth patterns of movement
- Backtracking kept to a minimum
Examples of changing conditions in plant layout (3)
- Considers demand growth or decline
- Considers product change over
- Considers technological change
Three main considerations in plant layout (3)
- Positioning
- Spacing
- Balancing
Its main objective consists of organizing equipment and working areas in the most efficient way and at the same time satisfactory and safe for the personnel doing the work.
Plant Layout
Main objectives of plant layout (4)
- Sense of unity
- Minimum movement of people, material and resources
- Safety
- Flexibility
It is dictated by the number and size of facilities, buildings, etc. and required spacing.
Plant Layout
It is usually based on the number of personnel or vehicles.
Plant Layout
Factors affecting plant layout (8)
- Materials
- Machinery
- Labor
- Material Handling
- Waiting Time
- Auxiliary Services
- The building
- Future changes
True or False: The layout of the productive equipment will depend on the characteristics of the product to be managed at the facility, as well as the different parts and materials to work on.
True
In consideration of the materials, what are the main factors to be considered, since these influence the manufacturing methods and storage and material handling processes? (5)
- Size
- Shape
- Volume
- Weight
- Physical-chemical characteristics
True or False: The sequence and order of the operations will not affect plant layout as well, taking into account the variety and quantity to produce.
False (it will affect)
True or False: Having information about the processes, machinery, tools, and necessary equipment, as well as their use and requirements is essential to design a correct layout.
True
True or False: The methods and time studies to improve the processes are not closely linked to the plant layout.
False (it is closely linked)
Things to consider in plant layout in terms to machinery (10)
- Type
- Total available for each type
- Type and quantity of tools and equipment
- Space required
- Shape
- Height
- Weight
- Quantity and type of workers required
- Risks for the personnel
- Requirements of auxiliary services
Organizational aspect of labor in plant layout (3)
- Direct labor
- Supervision
- Auxiliary services
Environment considerations in plant layout in terms of labor (5)
- Employee’s safety
- Light conditions
- Ventilation
- Temperature
- Noise
Process considerations in plant layout in terms of labor (4)
- Personnel qualifications
- Flexibility
- Number of workers required at a given time
- Type of work to be performed by the workers
True or False: Material handling does not add value to the product; it’s just a “waste”.
True
True or False: In plant layout, the objective is to maximize material handling as well as combining with other operations when possible, eliminating unnecessary and costly movements.
False (it should be minimized)
Other term for waiting time
Stock
True or False: In plant layout, the objective is a continuous material flow through facility, avoiding the cost of waiting time and demurrages that happen when the flow stops.
True
True or False: The material waiting to flow through the facility always represents a cost to avoid.
False (it is not always)
True or False: It is necessary to consider space for the required stock at the facility when designing the layout.
True
Example of waiting time or stock
Resting time to cool down or heating up
It support the main production activities at the plant.
Auxiliary Services
Categories of auxiliary services (3)
- Related to labor
- Related to material
- Related to machinery
Auxiliary services related to labor (4)
- Accessibility paths
- Fire protection installations
- Supervisions
- Safety
