Abstract

In this paper, a two stage production process is considered such that there is only one machine M1 in the first stage and two machines M2′, M2″ in the second stage. It is assumed that the output of M1 is the input for M2′, M2″. During the breakdown time of M1, a reserve inventory is suggested for M2′, M2″, to prevent the idle time, which is costlier. An inventory model is derived here based on certain assumptions to find the optimum size of the reserve inventory of the semi-finished product of the machine M1 to supply the machines M2′, M2″ till M1 resumes the function. Numerical illustrations are provided.
