process strategy and capacity planning
production process strategies
process focus
. a production facility organized around processes to facilitate
low volume, high variety
production
repetitive focus
. product oriented production process that uses modules (parts previously prepared), e.g. assembly line
product focus
. organized around products: product oriented, high volume, low variety process
mass customization focus
. rapid, low-cost production that caters to constantly changing unique customer desires
crossover points for different processes
. Total Cost A = Total Cost B
tools of process analysis
flowchart
. a drawing used to analyze movements pf people or material
time-function mapping
(process mapping). flow chart + time added on the horizontal axis
value stream mapping
. a process that helps understand how to add value in the flow of material and information through the entire production process
process charts
. charts that use symbols to analyze the movement of people or material
service blueprinting
. helps focus on the impact of customer interaction with the process
customer interaction in service processes
mass service and professional service
labor involvement is high
focus on human resources
selection and training is highly important
personalized services
service factory and service shop
automation of standardized services
restricted offerings
low labor intensity responds well to process technology and scheduling
tight control required to maintain standards
advances in recent production technology
machine technology
. increased precision, productivity, flexibility; reduced environmental impact; additive manufacturing; supports innovative product design
automatic identification systems (AISs) and RFID
. improved data acquisition; reduced data entry errors; increased speed; increased scope of process automation
process control
. real time monitoring and control of processes
vision systems
. accurate; modest cost; superior to individuals performing the same tasks
robots
. perform monotonous or dangerous tasks; perform tasks requiring significant strength or endurance; generally enhanced consistency and accuracy
automated storage and retrieval system (ASRSs)
. automated placement and withdrawal of parts and products; reduced errors and labor
automated guided vehicle (AGVs)
used for movement of products or individuals
flexible manufacturing systems (FMSs)
. enhance flexibility and reduced waste; produce low volume high variety; reduced changeover time and increased utilization
computer-integrated manufacturing
. extend flexible manufacturing
capacity
. the number of units a facility can hold, receive, store, or produce in a period of time
design and effective capacity
design capacity
. max output of a system under ideal conditions
effective capacity
. capacity firm
expects
to achieve
utilization
= actual output/design capacity
efficiency
= actual output/effective capacity
actual (or expected) output
= (effective capacity)(efficiency)
bottleneck analysis
. analyzing the limiting factor or constraint in a system
break-even analysis'
objective is to find the point, in dollars and units, at which costs = revenue
expected monetary value of capacity decision
net present value
