A resources provision policy for multi-unit maintenance program

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.
