An Application of Analytic Hierarchy Process (AHP) and Sensitivity Analysis for Maintenance Policy Selection

Abstract

Purpose: The purpose of this paper is to apply an analytic hierarchy process (AHP) for the evaluation/selection of maintenance policy.

Methodology/Approach: The paper adopts a case study approach of selecting most appropriate maintenance policy in the case of Slovenian paper mill company. Several steps of the AHP method are used in order to structure the decision-making process. Five possible alternatives are considered: failure based maintenance, preventive maintenance, total productive maintenance, reliability centered maintenance and total quality maintenance.

Findings: This paper proposes a framework for maintenance policy selection based on the AHP methodology. The framework was applied to select the most appropriate maintenance policy in a paper mill company. The results suggest that total quality maintenance is the most suitable concept for a paper machine. By performing a sensitivity analysis, it was revealed that the final outcome remained stable in all cases when the weights of the main criteria were increased for 25 percent.

Originality/value: The paper contributes to the literature by providing a framework for decision-making process regarding the maintenance policy selection. In addition, this paper utilizes an exponentially weighted moving average (EWMA) chart for performing a consistency test. Moreover, a sensitivity analysis also presents an important implication of this study.

The Relationship between Sustainability– Oriented Innovation Practices and Organizational Performance: Empirical Evidence from Slovenian Organizations

Abstract

Background and Purpose - The purpose of this paper is to empirically analyse the effects of sustainability-oriented innovation practices on the overall organizational performance. Further, this paper also aims to advance understanding of the measurement of corporate sustainability practices with the focus on innovation dimensions. Design/Methodology/Approach - The study uses data obtained from a survey of 116 organizations encompassing both the manufacturing and service industries in Slovenia. Descriptive statistics were used in order to determine the level of sustainability-oriented innovation practices deployment. Exploratory factor analysis was applied to extract the underlying factors and to provide a basis for assessing their reliability and validity. In addition, regression analysis was used to quantify the effect of sustainability practices on the organizational performance. Results - Data analysis result showed that sustainability-oriented innovation practices are significantly associated with organizational performance. Therefore, empirical evidence from this research confirmed the premise that building innovation competencies and integrating innovation activities in organization’s processes lead to performance benefits. This contributes to the debate about the potential for organizations to be sustainable and competitive. Conclusion - The presented research on corporate sustainability provides important theoretical and practical insights on which the deployment of sustainability-oriented innovation practices are conducive to fostering a broader set of performance benefits. As such, managers should increase organizations’ capacity for innovation which can be beneficial in terms of performance implications and achieving sustainability goals

Contingency Factors Influencing Implementation of Physical Asset Management Practices

Abstract

Purpose: The purpose of this empirical study is to examine the role of two contingency factors, i.e. uncertainty and competitiveness in relation to physical asset management (PAM) practices as well as to maintenance key performance indicators. The research is based on a premise that PAM, which was defined by risk management practices, performance assessment practices, life cycle management practices, and policy & strategy practices, has become an indispensable element of strategic thinking of asset owners as well as maintenance and asset managers. The purpose of this study is to advance the understanding of how organizations that face high or low level of uncertainty and competitiveness respond in terms of PAM deployment.

Methodology/Approach: This study employed a data set based on a large-scale survey among organizations in six European countries (i.e. Slovenia, Poland, Greece, Sweden, Turkey and Slovakia). Data were collected from 138 organizations located in the above-mentioned countries to conduct the study.

Findings: The results show that organizations that are faced with high level of uncertainty and competitiveness are more engaged in the deployment of PAM practices. Moreover, results show that when organizations are facing high levels of competitiveness they are using KPIs to a greater extent than organizations under low levels of competitiveness.

Originality/value: From a theoretical perspective, this study contributes to the contingency theory by providing empirical evidence whether a context-dependent approach to PAM is needed. The findings also provide insights for managers on how to respond to the competitive pressure as well as how to customize PAM practices in order to adapt to the changes in dynamic organizational environment.

Business Model Innovation: Insights from a Multiple Case Study of Slovenian SMEs

Abstract

Background and Purpose: Business model innovation (BMI) has become increasingly important, especially in the fast changing business environment. While large enterprises approach these changes systematically, small and medium sized enterprises (SMEs) are left to their own resourcefulness. For the purpose of developing dedicated methods and tools to support different SMEs in addressing these challenges, we have conducted a multiple case study to gain insights into factors that drive SMEs to innovate their BM, how they approach BMI and what changes they made to their BM.

Design/Methodology/Approach: First the framework of analysis was developed based on BMI research frameworks identified in literature review. Then the multiple case studies were conducted following the case study protocol developed by Envision project.

Results: Based on the proposed framework the results of four Slovene SME cases revealed differences between enterprises regarding the drivers behind BMI and changes in usage of the different BMI elements.

Conclusion: Overall, the results suggest all four SMEs, coming from different sectors, are facing BMI challenges without systematically addressing it and without using any dedicated BM ontologies or tools.
