A Resources Provision Policy for Multi-unit Maintenance Program

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 submodels 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.

The Behavior of Procurement Process as Described by Using System Dynamics Methodology

“…The model visualizes the interactions of all relevant goals and elements, presents the need for increased efficiency in the construction industry, and presents the role that KPIs have in driving these required efficiencies. Using system dynamics methodology, Cahyo et al [5] modeled the resource provision policy in multiunit maintenance program (emphasizing resource strategy involving human and procurement). The model is divided into several submodels, namely, human resource submodel, which focuses on policies related to provision and management, and procurement submodel, which emphasizes the procurement process and inventory system.…”
