most common production processes - answer1. repetitive 2. discrete 3. process manuf.
repetitive manufacturing - answer The same material is produced repeatedly over an
extended period of time at a relatively constant rate.
Discrete Manufacturing - answer different materials over time in batches, alternate b/w
materials
process manufacturing - answerproduction of materials like paint and chemicals, not
manuf. in individual units, instead in bulk
Difference in process manuf - answercan't take a part items made. individual raw
materials to make up product (side note)
two common production strategies - answer1. make to stock 2. make to order
make to stock - answerproduction process is triggered by a need to increase inventory
make to order - answerproduction process is triggered by need to fill specific customer
order
basic production process - answerRequest Production, Authorize Production, Issue raw
Materials, Create Product, Receive Finished Goods
The master data relevant to the production process are - answerbill of materials, work
center, product routing, material master, production resource tool
bill of materials for discrete and repetitvie manuf - answerCOMPLETE LIST of all the
materials both raw and semifinished goods that are needed to produce specified
quantity of material
Single-level BOM versus multi-level BOM - answercontains only one level in the
hierarchy versus contains more than one level
Nesting - answerrefers to a hierarchy in which a component in a bill of material has is
own bill of material. (this is done in SAP ERP to create multi- level BOM)
BOM includes header section: - answermaterial #, description, usage, validity, status,
and base quantity
, BOM includes items section: - answeridentifies all the materials needes to make the FG
and SFG identified in the header. ex) material #, description, quantity, and item category
Item Category - answeridentifies the type of material and influences how the material is
to be used in the BOM
IC: stock item - answermaterial for which inventory is maintatined; therefore it must
have material master
IC: nonstock item - answerinventory is not maintained therefore; it does not need a
material master
IC: variable size material - answeritems can be represented by same material #, but this
IC shows data concerning the size or dimension to be specified in BOM
IC: text item - answerused to include notes and comments within BOM
IC: document item - answerused to include documents such as drawings, assembly
instructions, photos, etc.
IC: Class items - answerused in variant BOM's to identify class or group of items; used
to create multiple versions of the same material instead of preparing seperate BOM
IC: Intra material or phantom items - answerlogically grouped set of materials that could
collectively be considered a single material.
ex) representing front and back wheels as set
work center - answerA location where value-added work needed to produce a material
is carried out; Resource used to produce a material
data used for work center is - answerbasic data, default values, cost center, hr
assignment, scheduling, capacities
WC: basic data - answer-includes name and and description of work center
-person responsible for maintaining master datat for center
-task list usage or list of operations required to complete a task
-standard value key are used to calc. how much time is used for each element
time elements in WC - answersetup time, processing time, and tear down time
default values in WC - answerfor operations performed at WC, examples are control
keys and wage data
control keys in WC - answerspecify how an operation is scheduled, how costs will be
calc, how operations will be confirmed once they are completed in WC
