ANALYSIS OF SPARE PARTS IN TERMS OF THEIR AVAILABILITY MANAGEMENT FOR THE PRODUCTION PROCESSES NEEDS

Abstract

Customer service is perceived as the ability to satisfy the requirements and expectations of customers, mainly as to the time and place of the ordered supplies, using all available forms of logistics activities. The specificity of the production process indicates that one of the main factors affecting the production continuity is the availability of spare parts for machines and equipment. The aim of the research was to develop a method of analysis of spare parts in terms of their availability management for the production processes needs, which can be used by logistics and maintenance managers. This article presents an analysis of spare parts availability management in terms of ensuring continuity of production resources. The proposed method supports the management of the availability of spare parts and is composed of two parts, ie. Spare parts classifications by two aspect: frequency of use and criticality criterion (for effective maintenance). Spare parts classifications by aspect of frequency of use divided items into three classes based on their history of consumption. Spare parts classifications by aspect of criterion for effective maintenance based on knowledge and experience of employees of the Maintenance Department and applying the AHP (Analytic Hierarchy Process) method. Based on the results of analyses and adopted criteria, among others such as: logistics costs of deliveries, time of waiting for delivery, place of storage of parts, time of preparation of machines for repair, etc. a decision algorithm has been developed for the selection of variants ensuring availability of a spare part.

This paper takes into account both literature analysis and business practice research on the basis of research projects (national and international) carried out at the Institute of Logistics and Warehousing and Poznan School of Logistics in Poland.
