COB 300 OPERATIONS CH 5 EXAM
QUESTIONS AND ANSWERS
Required cycle time for a process - Answer-dividing the time available to produce a
certain product by customer demand for the product
EX: if an automobile manufacturer needs to produce 1,000 automobiles during a shift
where the assembly line operates 420 minutes, the cycle time is:
( 420 minutes/1,000 automobiles x 60seconds/min)= 25.2 seconds/automobile
What is required to make something can be divided into 3 simple steps - Answer-1.
sourcing the parts we need
2. actually making the item
3. sending the item to the customer
depending on the item being produced, the supply chain can be very long with
subcontractors and manufacturing plants spread out over the globe or short where parts
are sourced and the product is made locally
Depending on the strategy of the firm - Answer-the capabilities of manufacturing, and
the needs of the customers, these activities are organized to minimize cost while
meeting the competitive priorities necessary to attract customer orders
Lead time - Answer-the time needed to respond to a customer order
Many make-to-stock firms invest in - Answer-lean manufacturing programs in order to
achieve higher service levels for a given inventory investment; focus is on providing
finished goods where and when the customers want them
One of the capabilities required for success **********emble-to-order environment is -
Answer-an engineering design that enables as much flexibility as possible in combining
components, options, and modules into finished products; have applied lean
manufacturing principles to dramatically decrease the time required to assemble
finished goods
Total number of combinations; - Answer-N1 x N2 x N3 etc...
in the make-to-order and engineer-to-order environments the customer order
decoupling point could be - Answer-either in raw materials at the manufacturing site or
possible even with the supplier inventory
Process selection - Answer-refers to the strategic decision of selecting which kind of
production processes to use to produce a product or provide a service.
, the formats by which a facility is arranged are defined by the - Answer-general pattern
of work flow; there are 5 basic structures
5 basic structures of work flow - Answer-1. project layout; the product remains in a fixed
location. For large or massive products produced in a specific location, labor, material,
and equipment are moved to the product rather than vice versa. Constant used parts
will be closer to layout than other parts- developed by arranging materials according to
their assembly priority
5 basic structures of work flow - Answer-2. work center; a process with great flexibility to
produce a variety of products, typically at lower volume levels; where similar equipment
or functions are grouped together (e.g drilling machines in one area and all stamping
machines in another). A part being worked on travels, according to the est. sequence of
operations, form work center to work center, where the proper machines are located for
each operation
most common approach is to arrange work centers in a way that optimizes the
movement of material; optimal placement often means placing work centers with large
amounts of interdepartmental traffic adjacent to each other.
EX: a work center for drilling holes, one for performing grinding operations, and a
painting area
5 basic structures of work flow - Answer-3. manufacturing cell; dedicated area where a
group of similar products are produced. These cells are designed to perform a specific
set of processes, and the cells are dedicated to a limited range of products. Typically
scheduled to produce "as needed" in response to current customer demand.
Formed by allocating dissimilar machines to cells that are designed to work on products
that have similar shapes and processing requirements. Widely used in metal fabricating,
computer chip manufacture, and assembly work
5 basic structures of work flow - Answer-4. assembly line; an item is produced through a
fixed sequence of workstations, designed to achieve a specific production rate. Usually
some form of pacing of time at each station is managed
Ex: assembly of toys, appliances, and automobiles; typically used in high-volume items
where the specialized process can be justified
5 basic structures of work flow - Answer-5. continuous process; a process that converts
raw materials into finished product in one contiguous process. Usually highly automated
& constitute one integrated "machine". Similar to an assembly line in that production
follows a predetermined sequence of steps, but the flow is continuous
ex: conversion and processing undifferentiated materials such as petroleum, chemicals,
and drugs
