Parallel SCM: Balancing Issues of Make-or-Buy and Supplier-Retailers Types

抄録

It is well known that SCM has an effect that reduces the extra stock and the cost of system, but how it can make all enterprises achieve the maximal profit is becoming the new problem in the institutional view. First, the two parallel SCM models are identified and formulated on the queueing base of Make-or-Buy and Supplier-Retailers types. Next, the problem of ellipse hypothesis in SCM is numerically discussed in the integral balancing view. Integral balancing means that both economics (profit) and reliability (workload) hold in autonomous balancing by cycle-time sharing. In particular, a feature map in a balance matrix is suggested for a win-win strategy, and is compared to the ellipse theory in the serial SCM type.
