| 要約: | This paper investigates a Supply Chain System for deteriorating items in
which a supplier supplies a manufacturer with raw material, and the
manufacturer produces the finished goods. Demand rate is assumed to be
time-sensitive in nature (Trapezoidal type), which allows three-phase
variation in demand, and production rate is demand dependent. Our adoption
of trapezoidal type demand reflects a real market demand for newly launched
product. We show that the total cost function is convex. With the convexity,
a simple solution algorithm is presented to determine the optimal order
quantity and optimal cycle time of the total cost function. Numerical
examples are given and the results are discussed.
