Maintenance strategy selection: a combined goal programming approach and BWM-TOPSIS for paper production industry

Abstract

PurposeCorrect and well-planned maintenance based on modern global methods directly affects efficiency, quality, direct production costs, reliability and profitability. The selection of an optimal policy for maintenance can be a good solution for industrial units. In fact, by managing constraints such as costs, working hours and human workforce causing sudden equipment failure, production and performance can increase.Design/methodology/approachTherefore, in this research a model was presented to select the best maintenance strategy at Kaghaz Kar Kasra Co of Iran. In this study, it was tried to integrate the two techniques of goal programming and the technique for order of preference by similarity to ideal solution (TOPSIS) to prioritize maintenance strategies. First, all factors affecting maintenance were identified, and based on the Best Worst Method (BWM) the degree of their importance was determined.FindingsAfter the evaluation, only 14 criteria in the 4 dimensions of cost, added value, safety and feasibility were selected. The highest points were given to the criteria of equipment cost and depreciation, equipment and personnel performance, equipment installation time and technical feasibility, respectively. In the next stage, using the TOPSIS method the item of maintenance strategy was ranked, and the 3 strategies of preventive maintenance (PM), predictive maintenance (PDM) and corrective maintenance (CM) were chosen. Modeling was performed utilizing a goal programming approach to select the optimal maintenance strategy for 13 devices. All the technical specifications, cost limits and the device time were extracted. After the model was finished and solved the best item for each device was specified.Originality/value1. Developing a goal programming model and decision-making dashboard. 2. Identifying the criteria and factors affecting the selection of the maintenance strategy for paper production Industry

Performance evaluation of bagasse-based cogeneration power generation plant utilizing IFLT, IF-FMEA and IF-TOPSIS approaches

“…With the progression of time, traditional TOPSIS transformed to fuzzy TOPSIS and IF-TOPSIS. Subsequently, these approaches were applied by several researchers in various fields -Credit risk evaluation (Shen et al, 2018); Site selection of wind power plant (Daneshvar Rouyendegh et al, 2018); Sustainable supplier selection (Memari et al, 2019); Paper process industry (Avakh Darestani et al, 2022); Foundry industry (Panchal et al, 2021). In the proposed model first three steps as followed to compute the ranking in IF-TOPSIS are similar to IF-FMEA.…”

Prioritizing the mitigation strategies to lean and green barriers using fuzzy BWM-FTOPSIS method in the food supply chain: an empirical case study

“…For example, Tu et al (2020) have used the fuzzy BWM-TOPSIS method to distinguish the relevance of different indicators of water security levels in various regions of North China. Avakh Darestani et al (2022) incorporated the BWM-TOPSIS approach to determine the best maintenance strategy in the paper production industry. Majumder et al (2022) used the fuzzy BWM-TOPSIS to identify the ideal alternative to enhance the effectiveness of the water treatment plant and found that the fuzzy BWM-TOPSIS approach is superior to fuzzy BWM-AHP and other methods.…”

Toward a new protection plan for Algeria's forest wealth focused on responsible citizenship: case of the Aures region

“…With: D ⊂ R n is a finite or non-finite set and f is a function of R n in R m Among the methods of mathematical programming allowing the treatment of the objective function of Eq. ( 1), let us quote the "Goal Programming -GP," retained in this study and that occupies a place of choice; in particular, to pursue several objectives at the same time (Avakh Darestani et al, 2020;Rifai, 1996).…”
