Analysis and modeling of maintenance operations in the context of an oil filling plant

Abstract

Purpose

The purpose of this paper is to present models and practical procedures for the analysis of maintenance operations and development of maintenance policies in the context of an oil filling factory. Basic maintenance models, maintenance policy selection and optimum spare part quantity determination procedures are illustrated with a specific case application in a factory.

Design/methodology/approach

Maintenance formulas are constructed and applied in a factory to determine down time due to various types of failures and maintenance practices in the system. Based on the analysis of the current system, a new preventive maintenance policy is proposed and its effect on reducing down time due to random failures is estimated by using the formulation developed. Procedures for spare part requirements and optimum order quantities with respect to total costs are outlined for critical spares.

Findings

Models and case study results presented in this paper demonstrate that selection of appropriate maintenance policy and optimum spare part order quantities should be based on scientific procedures since the results can significantly affect system performance.

Research limitations/implications

The results obtained in this paper are specific to the case application. However, the models and procedures presented are general and can be applied to any similar problems.

Practical implications

Formulations and procedures outlined in this paper can be used to determine effects of various types of maintenance activities and related policies on system performance. They can be valuable tools for maintenance engineers and operational managers in improving system productivity.

Originality/value

The paper considers a management problem related to maintenance policy selection and spare part order quantity determination in a factory. Detailed procedures outlined in this paper can be highly valuable tools for maintenance managers.
