This paper provides a comparative analysis of two sets of alternative
joint lot-sizing models for the general one-vendor, many-nonidentical-
purchasers case. Specifically, the basic joint economic lot size (irJE
LS) and individually responsible and rational decision (IRDD) models,
and the simultaneous setup cost and order cost reduction versions are
explored. Models for the latter situation are derived by the use of cl
assical optimization techniques. A numerical example is presented whic
h provides the basis for comparison of the models with the results of
independent optimization (10). For the basic models the previously rep
orted advantages of IRRD are refuted. In the simultaneous investment c
ase both the vendor and the purchasers realize significant savings ove
r IO when the JELS policy is followed. This is not true for IRRD. This
suggests that when an environment of co-operation between the parties
has been established the JELS is a superior policy.
