Abstract
Purpose
The purpose of this paper is to find the proper statistical distribution function, which can cover the failure time of a single machine or a group of machines. To this end, an innovative program is written in an Excel software, capable of assessing at least six statistical distribution functions. This research study intends to show the advantages of applying statistical distribution functions in an integrated model format to create or increase productive reliability machines. Productive reliability is a simultaneous combination of efficiency and effectiveness in reliability.
Design/methodology/approach
The method of theoretical research methodology comprises data collection tools, reference books and articles in addition to exploiting written reports of the Iranian Center for Defence’s Standards. The practical research method includes deploying and assessing the proposed model for a selected machine (in this case a computerized numerical control machine).
Findings
A comprehensive program in an Excel software having the capability of assessing at least six statistical distribution functions was developed to find the most efficient option for covering the failure times of each machine in the shortest time with the highest precision. This is regarded as the most important achievement of the present study. Furthermore, the advantages of applying the developed model are discussed and a large group of which have direct influences on the productivity of equipment reliability.

The purpose of this paper is to formulate a model which not only determines minimum level of maintenance requirements but also satisfies expected reliability level.
Abstract
Purpose
The purpose of this paper is to formulate a model which not only determines minimum level of maintenance requirements but also satisfies expected reliability level.
Design/methodology/approach
A multi‐objective decision making (MODM) model has been developed by viewpoint of decreasing wastes and increasing system reliability. Wastes that have been minimized are maintenance requirements (i.e. labor, spare parts, reserve system and productive maintenance activities) and maintenance system reliability that has been maximized is a function of maintenance requirements. This paper proposed goal programming model for decision‐making aid and a real case in an existing Iranian automobile manufacturing company was studied.
Findings
Output of the proposed model was optimum level of maintenance requirements which satisfies the expected reliability level. For example, outputs of model for man hour approximately are the same as available maximum level and inspection, service and test and adjustment activities are not necessary 12 times a year for all the machineries.
Practical implications
This model is useful for managers because they could use that in any maintenance systems and it would ensure them in achieving minimum level of maintenance requirements and the expected reliability level.
Originality/value
Since lean concept has appeared, many works have been done on decreasing or even eliminating of waste such as extra inventory. Although these studies have not taken into account expected reliability seriously, this paper considers these two issues together.

Abstract
Purpose
The aim of this study is to reveal the effects of “safety climate” on “productive organizational energy”, based on the idea that higher energy and productivity will be seen in employees with the improved safety climate in the working environment.
Design/methodology/approach
In this study, data were collected using an online questionnaire from 426 employees of small and medium-sized textile enterprises in the Organized Industrial Zone in the Turkish province of Gaziantep. The “easy sampling” method was applied, one of the sampling techniques not based on probability. Multiple linear regression analysis was used to examine the effects of the “Management's perspectives and rules” and “Colleagues and safety trainings” sub-dimensions of the safety climate on the “emotional”, “cognitive” and “behavioral” components of productive energy.
Findings
The findings showed that the safety climate in the workplace positively and significantly affects the productive organizational energy of employees. In addition, it was observed that the management's perspective and rules had a higher impact on productive organizational energy in attitudes towards the safety climate and productive energies of these employees compared to safety pieces of training.
Practical implications
First of all, the result of this study and the positive results that the safety climate in organizations might cause have been noted. It has been demonstrated that the productive energies of the employees will increase if the necessary safety climate is established in the enterprises. In addition, despite the importance attached to the safety training of the employees, as a result of the analysis, it has been determined that the management's perspective and rules (ß = 0.61; p < 0.01) have a higher positive effect on the productive energy of the employees. If these situations are considered by the managers, it is expected that the occupational health and safety management strategies created for the employees will contribute to the formation of positive behaviors in the employees.
Originality/value
The driving force of the present study is that, to our knowledge, there has been no research on this issue related to employees who are mentioned as a critical force in solving productivity and whose number is about 26 million in Turkey's population.

Abstract
Purpose
Due to the fact that most individuals tend to engage in some form of procrastination, it is important for organizations to investigate this phenomenon. The purpose of this study is to explore the impact of family–work conflict, grit, engagement and emotional exhaustion on productive procrastination for business-to-business salespeople. These specific antecedents are used to better understand what leads a salesperson to engage in productive procrastination in the workplace.
Design/methodology/approach
Using a Qualtrics panel, 305 business-to-business salespeople were surveyed to investigate what factors lead a salesperson to engage in productive procrastination. These salespeople were from a variety of industries to increase generalizability. All measures were taken from the extant literature. Partial least squares structural equation modeling was used to analyze the data.
Findings
Using the job demands-resources model as the framework, the results indicate that the type of engagement has a differential impact on a salesperson’s usage of productive procrastination such that cognitive engagement has a negative impact while emotional engagement has a positive impact on productive procrastination. Emotional exhaustion and family–work conflict lead to productive procrastination but grit minimizes productive procrastination usage.
Originality/value
To the best of the authors’ knowledge, this study is one of the first to explore the positive aspects of procrastination among salespeople. Specifically, this study focuses on productive procrastination and its antecedents. Relevant managerial implications that can help organizations better understand productive procrastination are discussed and examples are provided.

Abstract
Purpose
A major role of facilities management is ensuring the useability, reliability, and safety of the asset being managed. To achieve this management must use a system to control the maintenance function. The purpose of the paper is to identify and describe the various maintenance management models and systems available for facilities managers to consider.
Design/methodology/approach
Two comprehensive reviews of the literature were undertaken to categorise the various maintenance management models and identify popular models in practice.
Findings
The review identified 37 maintenance management models. From these, four were found to be popular: total productive maintenance (TPM), condition-based maintenance (CBM), reliability-centred maintenance (RCM), and condition monitoring (CM). While many thousands of papers can be found of these four models, the support in the literature for the remaining 33 models is very limited.
Research limitations/implications
While providing a sound foundation for future research, the papers findings are based solely on reviewing literature.
Practical implications
For facilities managers seeking to expand their knowledge of a particular model or maintenance management systems in general, the paper provides a practical understanding.
Originality/value
Papers focused solely on identifying and describing maintenance management models are scarce and this paper makes a concerted attempt to link academic research with management practitioners.

Abstract
Purpose
Maintenance and its management has moved from being considered a “necessary evil” to being of strategic importance for most competitive organisations around the world. In terms of the identification and use of organisational-wide maintenance management models the picture is not clears from both a literature and practical perspective. The purpose of this paper is to shed light on the various models and their use in real-world applications, and in doing so, explores the gap between academic research and practice.
Design/methodology/approach
For this paper two comprehensive reviews of the literature were undertaken, first, to identify and categorise the various maintenance management models, and second, to determine the depth of empirical evidence for the popular models in real-world applications. Descriptive analysis of both the practical examples and empirical evidence rates (EER) for maintenance related journals is provided.
Findings
Within the literature 37 maintenance management models were identified and categorised. From these, three models were found to be popular: total productive maintenance (TPM), condition based maintenance, and reliability centred maintenance. While several thousand papers discussed these three models, only 82 articles were found to provide empirical evidence.
Research limitations/implications
While providing a sound foundation for future research the outcomes are based solely on academic literature. Analysis of EER outside the field of maintenance is needed to make comparisons.
Practical implications
The paper offers practitioners a detailed contemporary overview of maintenance management models along with tabulated results of practical examples to present day organisations. Such practical-focused papers are very limited within academic literature.
Social implications
With EER as low as 1.5 per cent for some journals this paper acts as a reminder to researchers that they have an obligation to society to spend taxpayer funded research on addressing social needs and real-world problems.
Originality/value
This paper makes a concerted attempt to link academic research with management and operational practitioners. While the paper is critical of the current academic imbalance between theory and practice, a number of suggestions to improve EER are offered in the conclusions.

Abstract
Purpose
The purpose of this paper is to present a new operational approach to equipment maintenance designed to exploit the complementary nature of total productive maintenance (TPM) and reliability-centered maintenance (RCM).
Design/methodology/approach
This paper focuses on the operational aspect of the maintenance practice, proposing an equipment maintenance methodology that can be suitably adopted to define a new maintenance plan or check and improve an existing one. It integrates principles and methods of TPM and RCM and uses different tools to support decision-makers and operators. It proposes several worksheets which facilitate planning and implementing maintenance activities, that range from autonomous maintenance tasks to maintainability improvement actions.
Findings
This paper exploits the complementary nature of TPM and RCM to design or improve maintenance plans for a generic system. The tools and worksheets presented can be helpful to practitioners and operators.
Originality/value
While the integration of TPM and RCM is evidently a central issue in the maintenance management context, it has received limited attention in literature. To the best of the authors’ knowledge, it lacks a structured practical equipment maintenance methodology that exploits the complementary nature of TPM and RCM. Therefore, the approach presented in this paper would fill the current gap.

Abstract
Purpose
The purpose of this paper is to investigate the impact of total productive maintenance (TPM) and total quality management (TQM) practices on operational performance and their inter-relationship.
Design/methodology/approach
The present study includes three main constructs, namely, TPM, TQM and operational performance of pharmaceutical industry. Under TPM, four constructs, namely, disciplined maintenance, information tracking, housekeeping and operator involvement has been considered with the help of literature. In TQM, four constructs, namely, quality data and reporting, product innovation, research and development (R&D) management and technology management has been considered. Out of 410 Indian pharmaceutical plants contacted for survey, 254 responses have been used in the study for analysis. The factor analysis, path model and structural equation modeling has been used to analyze the proposed framework. The results for alternate models has been studied, interpreted and reported. Finally the direct and indirect effect of TPM and TQM on operational performance has been tested and checked for proving and disproving the hypotheses.
Findings
TPM practices have a significant impact on plant-level operational performance. When TPM and TQM practices are coming together to achieve operational performance, then TPM is having strong influence on operational performance. TQM is having significant support from TPM to achieve operational performance. TPM impact TQM and TQM in turn helps to achieve operational performance. TPM practices impact significantly R&D, product innovation and technology management, whereas quality data and reporting is the least contributor toward TQM. This may help industry to understand implications of implementation of TPM and TQM to achieve plant-level operational performance. TPM will help to reduce the cost of quality in terms of reduced scrap and less defective products.
Practical implications
The present study provides the useful insights to practicing managers. In literature it has been mentioned that TQM helps in TPM implementation. In practice TPM plays a great role to achieve quality in processes and therefore in products. In turn quality products, with reduced work in process inventory, less defective products and reduced scrap helps to achieve the operational performance at plant level. TPM practices will help the organization to improve the pace of product innovation and improvement in productivity, which is critical to pharmaceutical industry. The continuous monitoring of TPM practices can help organizations to run day to day operations and maintenance requirement of each machine over a specified period of time.
Originality/value
The present study diagnoses the inter-dimensional linkage between TPM, TQM and operational performance. The pharmaceutical industry is complex system of advance equipment’s and processes. After human resources, the health of machines/equipment’s describe the strength of an organization. The machines require the regular maintenance to produce the products with desired specifications. The specifications in medicines and very tight, which can be achieved only if machines/testing equipment’s are updated and maintained regularly. The TPM practices will helps the plants to achieve the operational performance by having quality in processes.

Abstract
A brief article considering the nature of total productive maintenance (TPM) and reliability‐centered maintenance (RCM) and the relationship between the two. Notes equipment management and empowerment of employees as key features of TPM. Sees the development of an effective preventive maintenance program as essential to effective equipment management and suggests that RCM is central to the development of such a program. Points out that, if implemented within the framework of TPM, RCM can help achieve better results from the TPM implementation.
