Abstract

Purpose

The purpose of this paper is to develop a preventive maintenance (PM) model for auxiliary components whose failures may not necessarily correspond to system failure but rather to faster system degradation.

Design/methodology/approach

The concept of load sharing was utilized to build a suitable Markov model for the problem. Regression analysis was used to estimate the various transition rates of the model. A real field application was used to illustrate the model.

Findings

Models addressing the design of an optimal PM strategy for such a problem are rare in the literature. The load‐sharing concept was borrowed and found very useful to model this problem. Regression analysis based on real field data was also found to be useful to estimate the model transition rates.

Originality/value

This paper addresses a problem that is not given enough attention in the currently available literature. Available models assume that a PM activity will restore the equipment to an as new, or at least to a better, condition. There exist situations, however, where a PM activity does not amend any damage but instead slows down further deterioration.

Abstract

Today's market environment is characterized by an increasing demand for greater product variety. This has inevitably led to decreased product life cycle and forced volume manufacturers to consider switching from the mass production of a limited range of products to lower volume production of a wider range. This trend is observable in moves towards lean production within the car industry.

Abstract

Purpose

The purpose of this paper is to provide comprehensive information on preventive maintenance (PM) planning and methods used in the industry in order to achieve an effective maintenance system.

Design/methodology/approach

The literature review is organized in a way that provides the general overview of the researches done in the PM. This paper discusses the literatures that had been reviewed on four main topics, which are the holistic view of maintenance policies, PM planning, PM planning concept and PM planning-based in developing optimal planning in executing PM actions.

Findings

PM policy is one of the original proactive techniques that has been used since the start of researches on maintenance system. Review of the methods presented in this paper shows that most researches analyse effectiveness using artificial intelligence, simulation, mathematical formulation, matrix formation, critical analysis and multi-criteria method. While in practice, PM activities were either planned based on cost, time or failure. Research trends on planning and methods for PM show that the variation of approaches used over the year from early 1990s until today.

Practical implications

Research about PM is known to be extensively conducted and majority of companies applied the policy in their production line. However, most analysis and method suggested in published literatures were done based on mathematical computation rather than focussing on solution to real problems in the industry. This normally would lead to the problems in understanding by the practitioner. Therefore, this paper presented researches on PM planning and suggested on the methods that are practical, simple and effective for application in the real industry.

Originality/value

The originality of this paper comes from its detail analysis of PM planning in term of its research focus and also direction for application. Extensive reviews on the methods adopted in relation to PM planning based on the planning-based such as cost-based, time-based and failure-based were also provided.

Abstract

Purpose

Construction projects in the oil and gas sector are greatly affected by external risk factors, especially those related to the economy, politics, security and stability factors. Hence, this research aimed to investigate the fundamental relationship between the external risk factors and their effects on the construction project success using Structural Equation Modeling method and PLS-SEM approach.

Design/methodology/approach

Data collected through a structured survey distributed to projects teams in the oil and gas sectors in Yemeni companies involved in mega construction projects. A hierarchical model for assessing causative external risk factors and their effects on project success was developed and analyzed using Smart PLS 3 software of SEM.

Findings

The findings showed that economic, political, force majeure and security-related risk factors had a strong effect on project success. Besides, the Coefficient of Determination (R-squared value) equals 0.743, represented the proportion of variation in the dependent variable(s), which can be explained by one or more predictor variable. Moreover, the predictive relevance value Q2 is 0.375 above zero, which indicates that the conceptual model can predict the endogenous latent constructs. The calculated Goodness of Fit (GoF) Index of the model was 0.699, which shows that the developed model had substantial explanatory power to represent the relationship between the cause of external risk factors to and the effect on construction project success.

Research limitations/implications

This research was limited to the oil and gas construction projects in Yemen as case study.

Practical implications

Practically, this study highlights the external risk factors that cause a negative effect on the success of oil and gas construction projects in Yemen. The research model of these factors is the first step in the risk management process to develop strategic responses for risks and explain the relationship between cause and effect on project success.

Social implications

The model of external risks factors that cause the failure of construction projects helps develop response strategies for these risks, thereby increasing the chances of project success reflected in the oil and gas sector, which is a main tributary of the national economy in developing countries.

Originality/value

There is a need to improve the planning of economic and security performance as well as to mitigate political risk factors effects on project success and other risk factors discussed in this study, which effect on construction project success according to their priorities.

Abstract

Purpose

The oil and gas construction projects are affected negatively by the drop in oil price in recent years. Thus, most engineering, procurement and construction (EPC) companies are opting to optimize the project mainly to mitigate the source of risks in construction to achieve the project expectation. Risk factors cause a threat to the project objectives regarding time, cost and quality. It is additionally a vital component in deviating from the client's expectation of productivity, safety and standards. This research aims to investigate the causes of risk in the oil and gas construction projects in Yemen.

Design/methodology/approach

A comprehensive literature review from various sources including books, conference proceedings, the Internet project management journals and oil and gas industry journals was conducted to achieve the objectives of this study. This initial work was predicated strictly on a literature review and the judgments of experts to develop the risk factor framework for the oil and gas construction projects in Yemen.

Findings

The authors found a few studies related to risk factors in oil and gas construction projects and shared a similar view about general construction projects. However, only a fraction of the factors accepted have included the variances of other studies on a regional basis or specific countries, such as the Yemen situation, due to the differences between the general construction industry and oil and gas industry. Moreover, the factors of these attributes were still accepted due to their applicability to the oil and gas industry, and no significant variances existed between countries. Research has indicated that 51 critical factors cause risks in the oil and gas construction projects in Yemen. Such risk factors can be divided into two major groups: (1) internal risk factors, including seven critical sources of risks, namely client, contractor, consultant, feasibility study and design, tendering and contract, resources and material supply and project management; and (2) external risk factors, including six sources of critical risk factors, namely national economic, political risk, local people, environment and safety, security risk and force-majeure-related risk factors. A risk factor framework was developed to identify the critical risk factors in the oil and gas construction projects in Yemen.

Research limitations/implications

This research was limited to the oil and gas construction projects.

Practical implications

Practically, this study highlights the risk factors that cause a negative effect on the success of oil and gas construction projects in Yemen. The identification of these factors is the first step in the risk management process to develop strategic responses for risks and enhance the chances of project success.

Social implications

The identification of risks factors that cause the failure of construction projects helps develop response strategies for these risks, thereby increasing the chances of project success reflected in the oil and gas sector, which is a main tributary of the national economy in developing countries.

Originality/value

This research is the pioneer for future investigations into this vital economic sector. Given the lack of resources and studies in the field of construction projects for the Yemeni oil and gas sector, the Yemeni government, oil companies and researchers in this field are expected to benefit from the results of this study. The critical risk factors specific to the oil and gas construction projects in Yemen should be further investigated with focus only on Yemen and its oil and gas industry players.

Abstract

In a system where two material flows with sequence dependency are matched, the use of real‐time information to monitor and control the sequencing buffer improves the system′s ability to schedule many different models, compared with a system with no information at all. In the latter case, the system is upset considerably when more than four different models enter the system. Shows how the performance of a car‐body shop is affected when real‐time information about progress in sub‐systems is available to the scheduler. A case study at a car plant and a simulation study were carried out.

Abstract

Purpose

The purpose of this paper is to explore Singaporeans’ view to a multicultural neighbourhood, specifically, their views on the Ethnic Integration Policy (EIP), a housing policy that promotes residential desegregation, and whether this policy has engendered a positive perspective to residential diversity.

Design/methodology/approach

A grounded theory approach is used to answer the following research questions: how do Singaporeans feel about residential diversity? Does the EIP influence attitudes to residential segregation in Singapore? What do these attitudes mean for governments and policymakers around the world? The research involved focus group discussions with 27 Housing and Development Board real estate agents, in order to tap onto their vast network of clients and better understand the prevailing sentiments on the ground.

Findings

The two major considerations when Singaporeans choose a flat are its price and location. Within the confines of these two factors, however, other considerations like race, nationality and the socio-economic makeup of a neighbourhood will influence their decisions.

Social implications

These considerations can be condensed into the factors of constrained choice and voluntary segregation. By limiting the impact of voluntary segregation, the EIP can be credited with bridging the racial divide. However, with constrained choice being unaddressed by the policy, the emerging formation of a class divide is an unintended consequence.

Originality/value

Because almost all developed economies are culturally plural, understanding Singapore’s approach to residential desegregation offers insights as to how other countries may learn from the Singapore experience in managing and encouraging multiculturalism, especially since ethnic residential concentration can reduce the formation of strong social relationships.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between employee loyalty (Organizational Commitment) and its two dimensions namely, affective commitment (AC) and continuance commitment (CC) with employee engagement.

Design/methodology/approach

A self-administered questionnaire was used for collecting the study data from 50 employees who represent three managerial levels from the government sector in United Arab Emirates (UAE). Three hypotheses were developed in order to test the said relationship. Hypotheses were tested through using various testes namely: the correlation coefficient and the regression analysis from the Statistical Package for Social Science software.

Findings

The findings indicated that there is a significant relationship between loyalty and engagement. AC was found to be more important in affecting employee's engagement when compared with CC.

Research limitations/implications

The study is based on a small number of employees working mostly in one single organization which limits the generalizability of the results; a limitation that does not allow for statistical generalization but allows for analytical generalization.

Originality/value

The study contributes to the literature of OC and more specifically to the relationship between employee loyalty and engagement in the UAE public sector. The outcome of the research draws decision makers’ attention to the importance of employees’ loyalty and its impact on their engagement.

Abstract

Purpose

The purpose of this paper is to look at how recent corporate scandals have translated into heightened interest in understanding various facets of corporate governance, notably the effectiveness of boards of directors and the composition of boards with particular attention to the gender dimension. In this context, the current study gauges the perceptions of Lebanese women managers regarding corporate governance issues pertaining to board effectiveness, roles and responsibilities and the benefits of female representation on boards.

Design/methodology/approach

The approach takes the form of a literature review and survey type questionnaire deriving from the literature. The questionnaire was administered to a sample of 61 top and middle level women managers, drawn from the context of 12 different banks in the Lebanese context.

Findings

The findings suggest that Lebanese women managers consider current board performance as not being satisfactory, that women are important board member candidates and that the low representation of women on boards in Lebanon is related to glass ceiling type impediments. They also believed that women board representation can reflect positively on the status of women at work and that government intervention is needed to level the playing field for women in management and at the boardroom level.

Originality/value

The value added of this research is to gauge Lebanese women's perceptions regarding corporate governance issues and the gender dimension, which is of direct relevance/interest to them. Moreover, these expressed perceptions are compared with what is reported in the literature, suggesting overall congruence between the experiences/perceptions of women in various contexts.

Abstract

Purpose

The purpose of this study is to explore the salience of glass ceiling type barriers in the Lebanese banking sector, based on the perceptions of a sample of Lebanese top and middle level women managers.

Design/methodology/approach

Literature review and survey type questionnaire molded after the women workplace culture questionnaire developed by Bergman and Hallberg. The questionnaire was administered to a sample of 61 top and middle level women managers, drawn from the context of 12 different banks in the Lebanese context.

Findings

The findings suggest that the common precepts of the glass ceiling theory are not supported in the context of Lebanese banks with overall positive inferences and perceptions reported by Lebanese women managers in relation to their work environment and daily work experiences. These findings are explained by the progressive evolution of the Lebanese banking sector over the past few decades.

Originality/value

The value added of this research is to revisit the salience of the glass ceiling in a non‐traditional context, namely Lebanon. While the findings encountered in the banking sector cannot be generalized to the entire Lebanese society, they nevertheless present an unexpected trend and potentially interesting implications stemming from an Arab‐Middle‐Eastern context.
