| Abstract: | This research addresses an approach to quantitatively evaluate economic,
environmental and quality differences among feasible product and process
alternatives. A mixed integer programming model is developed to select
from among manufacturing product and process alternatives while considering
the trade-offs of yields, reliability, and environmental impacts.
The emerging product, process and consideration of environment (EPPACE)
model evaluates those characteristics over time for which the manufacturer
is responsible. Most current approaches to evaluate different designs
with consideration of environmental impacts are qualitative tools which
do not take into consideration both cost and yield trade-offs. The
EPPACE model provides a decision tool to analyze the impact of pollution
minimization over time, waste attributed to poor quality, future legislation
and product take-back on the manufacturer. The assembly processing,
assembly rework, disassembly repair, refurbishment, and reclamation activities
are captured in the EPPACE model. Innovative modeling provides decision
variables for the amount of waste disposed in assembly and disassembly
periods in order to evaluate the cost of disposal and the value of recycling
capacities. Explicit constraints limiting material consumption, energy
consumption,
process waste generation, and packaging waste generation are modeled for assembly and disassembly periods. The EPPACE model is validated on a set of feasible product and process design alternatives for an electronics assembly case study. |
