Achieving and sustaining competitive advantage is a goal among firms, but it is increasingly challenging in a rapid changing and sophisticated environment. Most of the environmental management undertaken by firms in developing countries are not able to increase the competitive advantage of the product. Hence, this study investigates proactive capabilities that need to be developed in a dynamic environment where it involves green product innovation, environmental proactivity, alliance pro-activeness, and knowledge-based dynamic capabilities that impact on competitive advantage performance. This study involved a survey of 157 manufacturing firms with ISO 14001 certification throughout Malaysia. By implementing structural equation modelling approach, the results provided evidence of positive and significant direct effects of green product innovation and environmental pro-activity on firm’s competitive advantage. The relationship of alliance pro-activeness was fully mediated by the presence of knowledge-based dynamic capabilities as a condition to survive and prosper in a competitive market.

Firms are finding it increasingly important to leverage social media to facilitate knowledge access, get valuable feedback, and improve innovations to cater for emerging markets. However, using social media without integrating other key factors does not seem to add value to innovation efforts. Therefore, this study investigates the potential of social media usage (SMU) in enhancing green product innovation (GPI) and how two types of environmental collaboration may affect that relationship, which is a subject that has been under-explored. First, the literature on the expansion of the use of social media in enhancing GPI was reviewed to develop the theoretical framework and hypotheses. Then, data collected from 211 manufacturing firms were analysed using structural equation modelling to examine the proposed relationship. The results revealed that SMU does not directly influence GPI. Rather, internal environmental collaboration (IEC) and environmental collaboration with suppliers (ECS) fully mediate the relationship between SMU and GPI. The results further disclosed a positive relationship between IEC and ECS, where both types of environmental collaboration seem to be key factors in improving GPI. Hence, this study highlights the importance of knowledge sharing through environmental collaborations for the generation of ideas to improve products in order to remain competitive in the market.

Encountering a problem or error in the final stages of providing products or services increases costs and delays scheduling. The key task is to ensure quality and reliability in the early stages of the production process and prevent errors from occurring from the beginning. Failure mode and effect analysis (FMEA) is one of the tools for identifying potential problems and their impact on products and services. The conventional FMEA technique has been criticized extensively due to its disadvantages. In this study, the concepts of uncertainty and reliability are considered simultaneously. The processes of weighting risk factors, prioritizing failures by using the stepwise weight assessment ratio analysis (SWARA)–gray relational analysis (GRA) integrated method based on Ζ-number theory and complete prioritization of failures are implemented. Crucial management indices, such as cost and time, are considered in addition to severity, occurrence and detection factors along with assigning symmetric form of the weights to them. This, in turn, increases the interpretability of results and reduces the decision-maker’s subjectivity in risk prioritization. The developed model is implemented on solar panel data with 19 failure modes determined by the FMEA team. Results show that the proposed approach provides a more complete and realistic prioritization of failures than conventional FMEA and fuzzy GRA methods do.

This paper deals with the problem of transportation and quality within a Just-in-Time (JIT) inventory replenishment system. Formerly, transportation and quality problem are often modelled separately in most integrated inventory lot-sizing models. Hence, this paper develops an integrated vendor-buyer lot-sizing model by considering transportation and quality improvements into a JIT environment. The model is developed for minimising a total vendor–buyer system cost by optimising decisions such as delivery quantity, production batch, number of shipments, and process quality. Numerical examples and sensitivity analysis are provided to illustrate the proposed model. The developed model was also compared with an enumeration method to analyse the effectiveness of the proposed model to find the optimum solution. The results emphasise that the proposed model contributes to a new approach and obtains a near optimum solution for inventory replenishment decisions. The results are also beneficial to JIT practices as the model can improve the transport payload and reduce the chance of defective products and improving quality-related costs.

Establishing an effective eco-innovation strategy requires the firms to embrace changes and adapt to a dynamic environment, thus contributing to a competitive advantage. In this case, internal factors have a greater influence in forming a fit and effective business model. Nevertheless, internal factors can only be adapted with efficient capabilities responding to changes in the business environment. This situation rationalises why the internal capabilities of a firm need to be deeply explored and comprehensively developed. Literature indicates that most previous reviews concentrated on broad internal factors. Thus, this study complements the papers by specifying the particular capabilities on top of the wide factors. Through a systematic literature review, this study aims to present the lack of current research regarding the internal capabilities of manufacturing firms in enhancing eco-innovation. The literature was classified accordingly, presenting a framework with recommendations for future research. The results show that further study on internal eco-innovation capabilities is necessary by providing more attention to organisational culture and structure dimensions, specifically on the most crucial capabilities, dynamic, and integration. The findings also suggest that there is a need to measure the social, product development, and environmental performance. The situation presents an opportunity to investigate further internal capabilities that provide values to firms in managing resources and strengthening their ability to enhance eco-innovation performance.

This study proposed the use of an LCA supported by a design efficiency evaluation based on Design for Assembly principles to reduce the environmental impact of a product. To illustrate the methodology, a water leakage alarm (WLA) was selected as the object for a case study. Based on the identification and evaluation of the LCA results, it was inferred that the stage with the highest environmental impact was the manufacturing stage (75.35%), followed by the use stage (23.88%), the disposal of the WLA (0.64%), and finally, the disposal of the batteries (0.14%). For the manufacturing stage, the most interrelated categories were the hazardous waste and human toxicity, while the use stage was the main contributor to ozone depletion and acidification. Moreover, the disposal of the WLA and batteries contributed to the bulk waste. Furthermore, from the assembly evaluation, the design efficiency of the product was 14%. Two recommendations for improving the design of the WLA were: (1) to reduce the number of screws from three units to one unit, and (2) to eliminate the use of a cable and to replace it with a wireless component. By implementing both the proposed recommendations, the design efficiency was improved by as much as 34%. From the environmental perspective, there is not much difference between the wired alarm and wireless alarm. The wired alarm was considered to be more environmentally friendly in terms of product manufacturing but the wireless alarm has an advantage in terms of design and energy efficiency. By combining LCA and DFA design evaluation, a more comprehensive perspective of the product life cycle can be achieved.

Purpose The purpose of this paper is to investigate the implementation of sustainable manufacturing practices in Malaysian palm oil mills (POMs) by comparing the status of their current achievements and the levels of priority placed on their practices. Design/methodology/approach A questionnaire survey was used to collect data about 20 sustainable manufacturing practices from 51 POMs located in Malaysia. A five-point Likert scale was considered for recording variations in priorities and current practices with regard to sustainable manufacturing. A Cronbach’s α reliability test and a binomial test were undertaken to assess the internal consistency and the validity of the survey data. Spearman’s ρ correlation analysis was employed to determine the linear correlation between each of the sustainability practices identified. Factor analysis was conducted to reduce the number of sustainable manufacturing practices based on factor loading and to derive a clustering of these factors. Findings The results showed that employees’ well-being has the highest level in terms of both priority and current achievement. However, for other sustainable manufacturing practices, there was a difference where the current achievement of these practices in the Malaysian POMs was seen to be slightly lower than the priority given to them. Strong correlation of significant value was observed between the minimization of production waste and pollution prevention practices. From factor analysis, 15 practices of high factor loading were grouped into a proactive sustainability strategy and a preventive sustainability strategy. Research limitations/implications The study was still relatively exploratory. Future studies could investigate the barriers to the implementation of sustainable manufacturing practices at Malaysian POMs. The sample, which consisted of 51 Malaysian POMs, represented an important sector of the Malaysian economy. Reliance on stated, rather than revealed, preferences may limit the implications of the analysis undertaken for this study, but it does represent a major step forward in understanding the past in what was a highly recommended sector for investigation due to the paucity of extant data. A more broadly based, random sample of POMs from other countries would provide a better understanding of issues related to sustainable manufacturing practices. Practical implications The results of this study can be used by practitioners to adjust the sustainable manufacturing practices currently applied and further studies may go on to examine the reasons and implications for discrepancies between priorities and desired sustainability goals in more detail. Originality/value The survey conducted about sustainable manufacturing practices amongst Malaysian POMs was focussed on the three dimensions of sustainability, namely, the economic, environmental, and social elements involved.

Inventory replenishment decisions in supply chains usually benefit from economies of scale to minimize logistics costs; however, this approach may create a conflict between truckload utilization and economic ordering decisions. This paper proposes two Joint Economic Lot Size models that incorporate logistic costs (a function of shipping weight and distance) with two transportation modes: truckload (TL) and less-than-truckload (LTL) shipments. Additionally, a heuristic model is proposed to provide the solution when the mode of transportation is limited to TL and LTL shipments. The procedures for solving each model are developed based on two challenges in transportation: incapacitated shipments and capacitated shipments. Moreover, numerical examples are given to illustrate the proposed models based on four aspects: total costs, order quantity, the number of deliveries, and production batch quantity. The three proposed models are subsequently compared to reveal results for managers to consider for improving the performance of their supply chain.

The worldwide automotive industry sector has been experiencing a period of noticeable growth and success, especially since overcoming the financial crisis in 2008; however, this success is accompanied by remarkable erosion in the sales profit margin, causing automakers to invest in the after-sales and product–service system (PSS) sectors. The purpose of this review is twofold. First, it establishes an understanding of the automotive PSS concept by summarising and discussing the objectives, methodologies and findings of these studies. Second, it develops a framework to classify 102 articles analysed in depth and dating from 1999 to 2015 according to their adopted methodologies with an extended analysis of the most-used data collection instruments and analysis tools. It is evident that there is a tendency to utilise quantitative methods despite the expediency of implementing mixed methods in recent studies. This paper provides meaningful insights into the research methodologies, and for an audience consisting of general researchers and practitioners with an interest in conducting research in the automotive PSS and production disciplines, it represents a guideline to choose the appropriate research methodology, taking into consideration the advantages and disadvantages of each one.

This paper analyses the importance of embedding the importance of commercialisation of University’s research in the Engineering education in Malaysia. By conducting courses or program about this commercialization aspects by the engineering faculty, the commercialization process for the university will be sustained in future. The literature so far reviewed shows that engineering education processes have been extensively studied to study the best mechanism and model for engineering education in Malaysia. Aiming to contribute to such literature, we look at the current practice of Engineering Faculties under the Malaysian Research Universities in order to see to what extent aspects of commercialization of university’s research are incorporated in their syllabus. We found that the aspect of the commercialization of university‘s innovation are less exposed to engineering students in Malaysia. This paper suggests that it is vital to incorporate the commercialization of university’s research aspects into the engineering syllabus to develop the culture of entrepreneurship among engineering students which eventually assists the university to commercialize its’research.
