Abstract
-
A System Dynamics model for resource provision policy in multi-unit
maintenance program is developed. First, a scheme is developed to formulate and
evaluate policies regarding the provision under uncertain condition or resource
requirement in a period of planning to result in minimum maintenance cost. The
model emphasizes on resourcing strategy involving human and procurement. It is
composed of 3 sub-models presented in a causal loop modelling. The human
resource sub-model focuses on policies related to provision and management. The
procurement sub-model takes into account the procurement process and inventory
system. Due to data availability, the verification has encloses only the relation
between maintenance and human resources but further application on wide range
of resources through case studies is intended. The advantage of this model is
related to its wide outlook of interrelated variables of a complex multi-unit
maintenance system. This model can show the impact of one decision in a certain
maintenance resourcing system on the other maintenance resourcing system and
will lead to an optimum policy for maintenance resource provision system.
