Bus 140 Operations Supply Chain Ch 7

A load summary chart

provides historical data on the movement of parts and materials between departments.

Effective layouts help with

reduce material handling costs, reduce material handling costs, and improve communication and interaction among workstations.

A format for displaying manager preferences for departmental locations is known as

relationship diagram.

To maximize an assembly line's efficiency

the line's balance delay must be minimized.

Cycle time refers to

the time between finished units coming off an assembly line.

A company has a target output rate of 40 units every five (5) hours when its line is fully operational. To achieve this target the firm must have a cycle time of

7.5 minutes or less

capacity expansion strategy helps with

Capacity lead strategy, Capacity lag strategy, and Average capacity

"area" of disadvantage of cellular layouts is

Capital investment

Facility layout

Effective layouts also: minimize material handling costs, utilize space and labor efficiently, eliminate bottlenecks, facilitate communication, eliminate waste, incorporate safety and security measures, promote product and service quality, encourage proper maintenance, provide for visual control, provide for greater flexibility, and increase capacity.

Facility layout

Facility layout refers to the arrangement of machines, processes, departments, workstations, storage areas, aisles, and common areas within an existing or proposed facility

Examples of basic facility layout are

Fixed-position, Product and process

Examples of hybrid facility layout

Mixed-model, Cellular, and Flexible manufacturing

Similar activities are grouped together in departments or work centers according to the function with a

Process layout

Facility layout

The basic objective of the layout decision is to ensure a smooth flow of work, material, people, and information through the system.

A flexible manufacturing system (FMS) combines flexibility with higher efficiency

True

A process layout groups similar activities together according to the functions they perform.

True

A relationship diagram provides a standard format for displaying manager preferences for department locations.

True

A schematic diagram using weighted lines to denote location preference is called a relationship diagram.

True

Block diagramming is a design tool for process layouts that takes into account the number of adjacent and non-adjacent moves.

True

Capacity can be increased in one large step or incrementally.

True

Cellular layouts combine the flexibility of process layouts with the efficiency of product layouts.

True

Facility layout refers to the arrangement of machines, processes, departments, and other areas within a facility.

True

Fixed-position layouts are used for projects when the product cannot be moved.

True

For a given facility the best operating level equals the percent of capacity utilization that minimizes unit cost.

True

General as opposed to specific purpose equipment is typically found in a process layout.

True

Increasing capacity utilization beyond the best operating level results in dis-economies of scale.

True

Line balancing is constrained by precedence requirements and cycle time restrictions.

True

Material storage and movement are directly affected by facility layout decisions.

True

Minimizing material handling cost is an important objective for a process layout.

True

Precedence requirements reflect physical restrictions on the order in which operations are performed in a product layout.

True

The balance delay is calculated by subtracting efficiency in percent from one hundred.

True

The capacity cushion for a facility equals one minus utilization.

True

The cycle time refers to the maximum amount of time a product is allowed to spend at each workstation.

True

The efficiency of a flexible manufacturing system (FMS) comes from reductions in setup and waiting times.

True

The line-balancing procedure uses heuristics to specify which work elements are allocated to each workstation.

True

The major layout concern for a process layout is where to locate departments or functional areas relative to each other.

True

The majority of service facilities utilize process layouts.

True

The time to complete a task in a mixed-model assembly line can vary from model to model.

True

With a product layout the purpose of line balancing is to equalize the amount of work at each workstation.

True

product layouts are efficient; process layouts are flexible

True

The material storage space required for in-process inventory is typically larger in

a process layout

A schematic diagram that uses weighted lines to denote location preference is known as a

a relationship diagram

With a product layout

activities arranged in a line according to the sequence of operations.

Two techniques used to design process layouts are

block diagramming and relationship diagramming

One of the best known computerized packages available for designing process layouts is CRAFT. CRAFT stands for

computerized relative allocation of facilities technique.

With line balancing the maximum amount of time the product is allowed to spend at each workstation is known as the

cycle time

Advantages of cellular layouts are

easier to automate, control and reduces setup time

A grid layout encourages customer

encourages customer familiarity, has low costs, and is easy to clean,

A process layout is when

equipment is general purpose and the workers are highly skilled

A type of service layout designed to encourage browsing and increase impulse purchasing is known as a

freeflow layout

In-process inventory is

high because material moves from work center to work center in batches waiting to be processed

Production flow analysis

is a group technology technique that reorders part routing matrices to identify families of parts with similar processing requirements.

In a product layout, the process of assigning tasks to work stations is referred to as

line balancing

The process of equalizing the amount of work at each workstation in a product layout is known as

line balancing

"area" of advantage of cellular layouts are

material handling, setup time, and control

factors to the design and operation of a mixed-model assembly line are

model sequencing, line balancing, and u-shaped lines

Material handling equipment that can follow multiple paths, move in any direction, and carry large loads of in-process inventory is most likely to be associated with a

process layout

Storage space in a process layout is large to accommodate the large amount of in-process inventory.

process layout

Most service organizations use

process layouts
