Tenant selection is an important strategic and operational problem for
large property investment and management companies. This paper presen
ts an evolutionary prototyping project developed in conjunction with a
long term programme of establishing a property management information
system for a known company. The project aims at developing a tenant s
election decision support system (TSDSS) which employs a multi-criteri
a analysis technique as its evaluation tool. TSDSS also introduces a n
ew method for determining the alternatives to be considered in the sel
ection process, so that the values of some criteria, which represent t
he characteristics of the combinations of the chosen tenants, can be o
btained. The alternative generation method has actually improved the p
racticality of using Multi-Criteria Analysis (MCA) techniques in some
real life situations. However, from this development, some basic probl
ems of using this technique have been revealed.
