Abstract

Purpose

The purpose of this paper is to introduce a practical integrated overall equipment effectiveness (OEE) framework that encompasses the core characteristics of OEE.

Design/methodology/approach

The paper reviewed the backgrounds of OEE and improvement frameworks and explored the limitations. An integrated OEE framework was developed by synergizing the strengths of OEE and improvement frameworks to complement the shortcomings. This new framework underlies the OEE concepts and provides structural improvement steps. It was applied to systematically assist and guide OEE practitioners in a case study.

Findings

The review of OEE literature found that there is a lack of improvement frameworks with systematic steps specifically developed for OEE implementation. Conversely, a review on improvement frameworks of different methodologies revealed that they do not fully capitalize on the use of performance measures as benchmarks and improvement drivers. An integrated framework that incorporated the advantages of both OEE and conventional improvement frameworks was developed and validated through a case study over a period of 38 weeks. The OEE performance before the improvements was low (73.4 percent) due to high availability losses (76.5 percent). Both OEE and availability achieved the target of 76.5 percent and 80 percent, respectively, after using the framework for improvements.

Research limitations/implications

The reviewed papers represent a sample of papers present in the literature and were selected based on relevancy. A greater number of papers incorporated into the literature review would certainly bring out a more comprehensive study.

Practical implications

The proposed integrated OEE framework provides OEE practitioners with systematic directions and steps combined with benchmarking and loss prioritization features for effective improvement efforts. In addition, it provides overview for the practitioners to make better decisions in project management. This helps address the common issues of practitioners not sure of what the next improvement step is. A case study using the proposed framework at a semiconductor company had successfully achieved the OEE benchmarks and set target for conversion time.

Originality/value

This paper provides a new integrated OEE framework offering a systematic approach toward implementing OEE improvements.

Abstract

Purpose

As suggested in many previous studies, good thermal comfort and indoor air quality (IAQ) played a significant role in ensuring human comfort, health and productivity in buildings. Hence, this study aims to evaluate the thermal comfort and IAQ conditions of open-plan office areas within a green-certified campus building through a post occupancy evaluation.

Design/methodology/approach

Using the field measurement method, environmental dataloggers were positioned at three office areas during office hours to measure the levels of thermal comfort parameters, CO2 concentrations and the supply air rates. At the same time, questionnaires were distributed to the available office staff to obtain their perception of the indoor environment. The findings were then compared with the recommended environmental comfort ranges and used to calculate the thermal comfort indices.

Findings

Results show that the physical parameters were generally within acceptable ranges of a local guideline. The neutral temperature based on the actual mean vote at these areas was 23.9°C, which is slightly lower than the predicted thermal neutrality of 25.2°C. From the surveyed findings, about 81% of the occupants found their thermal environment comfortable with high adaptation rates. A preference for cooler environments was found among the workers. Meanwhile, the air quality was perceived to be clean by a majority of the respondents, and the mean ventilation rate per person was identified to be sufficient.

Research limitations/implications

This study focussed on the thermal environment and air quality at selected office spaces only. More work should be carried out in other regularly occupied workplaces and study areas of the green educational building to allow a more thorough analysis of the indoor air conditions.

Practical implications

This paper highlights on the thermal comfort and air quality conditions of the air-conditioned office spaces in a green-certified campus building and is intended to assist the building services engineers in effective air conditioning control. The findings reported are useful for thermal comfort, IAQ and subsequently energy efficiency improvements in such building type where adjustments on the air temperature set-point can be considered according to the actual requirements. This study will be extended to other green campus spaces for a more exhaustive analysis of the indoor environment.

Originality/value

There is limited information pertaining to the environmental comfort levels in offices of green campus in the tropics. This study is, therefore, one of the earliest attempts to directly explore the thermal comfort and IAQ conditions in such workplace using both on-site physical measurement and questionnaire survey.

Abstract

Purpose

This research aims to provide systematic insight into the current maturity of augmented reality (AR) and virtual reality (VR) in operations and supply chain management (OSCM), by analyzing the existing literature, contemporary concepts, data and gaps for future research directions.

Design/methodology/approach

This research uses information from existing literature regarding timeline trends, publishers, research design and method, industry engagement, geographic location, active authors and affiliated universities, concentrated topics, theories and maturity in its review. A collection of publishing databases from 1997 to 2021 were explored using the keywords “Augmented Reality,” “Virtual Reality” and “Operations” and/or “Supply Chain” in their title and abstract to examine which publications to be included. Based on the search, a total of 164 journal articles were selected, and information on a chain of variables was collected.

Findings

There has been a significant publication growth over the past 25 years regarding the adoption of AR/VR in OSCM. Key findings indicate that 52% of the publications were focused on manufacturing, with only 10% of the existing literature using background theories. AR/VR can be observed at the introduction and growth phase and have yet to reach their maturity. Furthermore, there is limited utilization of AR/VR as drivers in facilitating sustainable practices in OSCM by academics and practitioners, albeit a strong promise exists. Finally, the prospective applications of AR/VR toward post-COVID-19 supply chains recovery require special attention.

Research limitations/implications

This systematic review is limited to considering only academic articles available from Emerald, Elsevier, Taylor and Francis, Springer, Scopus, JSTOR and EBSCO containing the keyword parameters.

Originality/value

The study used a bibliometric review to identify the trends and maturity in the evolution of AR/VR in OSCM. This research provides a better understanding of current research practices and offers directions toward the adoption of AR/VR in OSCM.

Abstract

Purpose

There are ten universal principles of United Nations Global Compact in four areas namely human rights, labour, environmental and anti-corruption, and this chapter will explore the sixth principle of labour standard on elimination of discrimination in employment and occupation, in particular the doctrine of constructive dismissal in Malaysian labour relations. Constructive dismissal is creating a new challenge in labour relation in Malaysia.

Methodology/approach

This chapter specifically analyses some of the constructive dismissal awards and its implication to labour relations in Malaysia. The methodology employed in this chapter is the analysis of case laws using criterion-based sampling from the Industrial and Superior Court awards on constructive dismissal.

Findings

There has been an increasing number of awards on constructive dismissal made by the Malaysian Industrial Court over the last nine years. From the year 2009–2013, the Industrial Court has made 663 awards on constructive dismissal, mostly against employers. With compensation awarded to each employee amounted to as much as 24 months of back-pay salary plus a month’s pay for every year of service, employers can no longer neglect this pressing issue.

Research limitations/implications

The concept of constructive dismissal falls within the purview of section 20 of the Industrial Relations Act 1967 in Malaysia. Constructive dismissal is a ‘deemed dismissal’ if an employer is guilty of a breach of the employment contract which goes to the root of the contract. It arises when a workman terminates his/her contract of employment and considers himself/herself discharged from further obligations because of the employer’s conduct.

Practical implications

With a good understanding of the constructive dismissal awards, it is expected that organizations will manage and treat their human resources as their greatest assets and prevent constructive dismissal claims from taking place. This will eventually help to improve and maintain harmonious labour relations. This chapter is likely to provide insights into the Malaysian labour relations environment for international business operations.

Originality/value

In the context of Malaysian labour relations, studies on constructive dismissal are limited as it is considered as a new area and a specific area of study. This chapter therefore hopes to fill the existing gap in the literature, to highlight some of the recent awards and lessons to prevent constructive dismissal claims from taking place and generally to contribute to the constructive dismissal literature.

Abstract

Purpose

This paper aims to propose a comprehensive methodology for setting up rural electrifications for indigenous villages with minimum budgets and the lowest possible cost of electricity (COE). The electricity accessibility of rural area in Malaysia is not fully covered and the cost of extending the grid to these areas can be high as RM 2.7m per km. Lack of vigorous policies and economic attraction of the rural areas are also the main barriers to rural electrification. Electricity is an essential element of economic activities and the lack of electricity exacerbates poverty and contributes to its perpetuation. Therefore, a hybrid standalone power system can be an alternative solution for the rural electrification. A hybrid standalone power system is studied to investigate the potential of the implementation and the budget required.

Design/methodology/approach

A site survey has been carried out in a village in Peninsular Malaysia, namely, Kampung Ulu Lawin Selatan. A standalone hybrid system is modeled in HOMER Pro software and the data collected from the selected site are used to obtain the system configuration with the lowest COE. The load following and cycle charging energy dispatch methods are compared to identify the optimal system configuration that yields the lowest COE. The diesel generator-only system is chosen as a benchmark for comparisons.

Findings

The results show that the hybrid system constituted from the diesel generator, photovoltaic (PV), micro-hydro and energy storage using the load following energy dispatch method yields the lowest COE of RM 0.519 per kWh. The COE of the hybrid system is 378 per cent lower than that of the diesel generator-only system. The lead-acid energy storage system (ESS) is able to reduce 40 per cent of COE as compared to the system without ESS.

Originality/value

The results indicate that the COE of the diesel-micro hydro-PV-ESS system with load following dispatch strategy is RM 0.519 per kWh, and this value is 35 per cent higher than the average electricity price in Malaysia. However, it is important to note that the costs of extending the grid to the rural area are not taken into account. If this cost is considered into the electricity price, then the standalone hybrid power system proposed by this study is still a competitive alternative for rural electrification.

Abstract

Corruption has been defined in different ways by various scholars and organizations according to cultural, legal, or other factors (Organization for Economic Co-operation and Development, 2008, p. 22). The word “corruption” is derived from the Latin word corruptus and, according to the dictionary, it has six possible meanings: dishonesty for personal gain; depravity; undesirable change; corrupting of something; altered word or phrase; or rotting.1 However, the most useful typology of contemporary social science definitions of corruption is Arnold J. Heidenheimer's typology of three major types of definitions (Heidenheimer, 1970, pp. 4–6).

Abstract

Corruption was a serious problem in Singapore during the British colonial period and especially after the Japanese Occupation (February 1942–August 1945) mainly because of the lack of political will to curb it by the incumbent governments. In contrast, the People’s Action Party (PAP) government, which assumed office in June 1959 after winning the May 1959 general election, demonstrated its political will with the enactment of the Prevention of Corruption Act (POCA) in June 1960, which strengthened the capacity of the Corrupt Practices Investigation Bureau (CPIB) to combat corruption effectively. Indeed, Singapore’s success in curbing corruption is reflected in its consistently high scores on Transparency International’s Corruption Perceptions Index (CPI) from 1995 to 2012 as the least corrupt country in Asia. Singapore was ranked first with Denmark and New Zealand in the 2010 CPI with a score of 9.30. Similarly, Singapore has been ranked first in the Political and Economic Risk Consultancy (PERC) annual surveys on corruption from 1995 to 2013. Why has Singapore succeeded in minimizing the problem of corruption when many other Asian countries have failed to do so? What lessons can these countries learn from Singapore’s experience in combating corruption? This chapter addresses these two questions by first describing Singapore’s favorable policy context, followed by an identification of the major causes of corruption during the British colonial period and Japanese Occupation, and an evaluation of the PAP government’s anti-corruption strategy.

Abstract

Singapore is perceived to be the least corrupt country in Asia according to Transparency International's Corruption Perceptions Index (CPI) from 1995 to 2010. In 2010, Singapore was ranked joint first with Denmark and New Zealand among 178 countries on the CPI with a score of 9.3. However, this does not mean that corruption does not exist in Singapore, which has its share of corruption scandals too. Indeed, the scandal involving Teh Cheang Wan attracted a great deal of attention because he was the Minister for National Development in Singapore from 1979 to 1986.
