Purpose - The purpose of this paper is to empirically identify the post-implementation impact of enterprise resource planning (ERP) systems on work and work-life of managerial-level end-users, in terms of problem-solving support, job discretion, management visibility and cross-functionality, authority and decision rights, and overall impact on organization, in Sri Lanka. Design/methodology/approach - Survey methodology was used and managerial-level end-users who fulfilled the selection criteria set for the study, responded. The hypothesized relationships were examined using structural equation modelling. Findings - It was found that "ERP system product performance" significantly predicts "problem solving support", "job discretion, management visibility and cross-functionality", and "impact on organization". However, the direct link between "ERP system product performance" and "authority and decision rights" is not significant. Originality/value - The literature suggests that the impact of ERP systems on individuals and organizations can be conceptualized in terms of individual users' perceptions and beliefs about the changes which occurred after the implementation. However, the main shortcoming of past studies is that they included a limited number of consequences of ERP adoption in a single study. © Emerald Group Publishing Limited.

Stress and Health | Year: 2010

The aim of this paper is to examine the moderating effect of coping strategies on the relationship between work-related dimensions (i.e. work routinization, role clarity, relationships with others and promotional opportunity) and job stress. For the study, a convenience sample of 385 white-collar employees, full-time employed in various types of private sector organizations, belong to different industries and ranked at different levels within the organizations responded. The factor analysis led to identify four broad coping strategies that individuals use, namely, individual positive coping, workplace initiatives, workplace informal support and individual destructive coping. It was found that both individual positive coping and workplace initiatives moderate the relationship between 'relationships with others' and job stress. However, none of the coping strategies have moderated the relationship between job stress and the other three work-related dimensions. Copyright © 2010 John Wiley & Sons, Ltd.

Waste is one of the most pressing problems faced by the whole world. Electronic waste is the latest in the Sri Lankan waste stream. Literature revealed many electronic waste management concepts, strategies and models implemented worldwide to counter the electronic waste menace, inclusive of electronic waste management policy developed in Sri Lanka to manage electronic waste generation. The purpose of this paper is to explore probable suggestions to improve existing electronic waste management practices, with special emphasis on enhancement of national policy of electronic waste management in Sri Lanka. The research problem was approached by case study method since it facilitates an in-depth investigation. Multiple case study design was applied by employing three case studies. Cases were selected considering major types of electronic waste which exhibit high penetration rates within country: namely (1) household appliances, (2) IT and telecommunication equipments and (3) lighting equipments. Cross-case analysis and code-based content analysis techniques were applied in data analysis phase of the research. Four expert interviews were conducted to further verify proposed improvements to existing electronic waste management practices. Case study findings revealed issues in electronic waste minimization and handling processes that need special attention. Empirical findings further revealed less government commitment and ineffective government procedures as critical issues in electronic waste management. Procedures of imports and exports, waste minimization, waste collection, storage, treatment and disposal, legal framework, capacity building and awareness, implementation and coordination mechanisms, monitoring, evaluation, reporting and resource mobilization can be identified as major areas for national policy enhancement. Consequently, the national policy of electronic waste management can be implemented as a national strategy to manage electronic waste generation in Sri Lanka. © 2012 Elsevier B.V.

The issue of subjectivity in assigning weights for the domains and aspects in sustainability rating systems has not received much attention, and is hence explored in this study. A survey carried out among building construction sector professionals in a particular national context sought relative weights for various domains and aspects. Both direct ranking and analytic hierarchy process (AHP) methods were used. Reasonable agreement, with some differences, was found among architects, engineers and quantity surveyors on the relative weights for the six domains of Site, Energy efficiency, Water efficiency, Materials, Indoor environmental quality and Waste & Pollution; and also for the aspects. The overall domain weights were compared with those assigned in eight other rating systems, originating from eight different countries. While the Sri Lankan survey assigned the highest weight for the Site domain (with Energy efficiency a close second), in most other systems the Energy efficiency domain was top ranked. Relevant national indicators were chosen for 3 of the 6 domains, and the values of these indicators for the 9 countries were compared with the varying weights for the corresponding domains in the rating systems originating from those countries. Good correlation was found between the indicators and the weights. © 2013 Elsevier Ltd.

Hybrid energy systems (HESs) are becoming popular for standalone applications due to global concern regarding green house gas (GHG) emissions and depletion of fossil fuel resources. Research in the optimal design of HESs is ongoing, with numerous optimization techniques giving special emphasis to Pareto optimization, incorporating conflicting objectives. The subsequent decision-making process including the non-dominant set of solutions has yet to be addressed.This work focuses on combining multi-objective optimization with a multi-criterion decision making (MCDM) technique to support decision makers in the process of designing HESs. Four different objectives, i.e., levelized energy cost (LEC), unmet load fraction, wasted renewable energy (WRE) and fuel consumption are used to obtain the Pareto front. A decision support tool based on Fuzzy TOPSIS and level diagrams is proposed to analyze the Pareto front and support the subsequent decision-making activity. A case study is used to illustrate the applicability of the proposed method. The study shows that the novel method is useful when determining the relative weights of objectives, providing a detailed picture of the objective space to the designer when coming up with the optimum system. The technique proposed in this study can be further extended to analyze similar problems in energy system design where MCDM is necessary after multi-objective optimization. © 2013 Elsevier Ltd.

HES (hybrid energy system)s are becoming energy systems of choice for standalone applications due to ever increasing fuel costs and global concern on GHG (Green House Gas) emissions. However, it is difficult to justify the higher ICC (Initial Capital Cost) of renewable energy components, especially for rural electrification projects in developing countries. This paper illustrates the modeling and simulation of HESs, and multi-objective optimization carried out in order to support decision-making in such instances. LEC (Levelized Energy Cost), ICC and GHG emission were taken as objective functions in the optimization and the sensitivity of market prices and power supply reliability was further evaluated. Results depict that Pareto front of LEC, ICC and GHG emission can be simplified as a combination of ICC-LEC and LEC-GHG emission Pareto fronts making the decision-making process simpler. Gradual integration of renewable energy sources in a number of design stages is proposed for instances where it is difficult to bear the higher ICC. Finally, importance of planning integration of renewable energy sources at early design stages of the project is highlighted in order to overcome the difficulties that need to be faced when coming up with the optimum design. © 2013.

Microgrids can operate in parallel with the grid or as a power-island. They are thus, expected to perform seamless transition from islanded to parallel operation and vice versa. This paper reviews the existing DG interconnection standards for microgrid resynchronization, investigates possible simple solutions for voltage balancing, and shows that the existing synchrocheck relay with a circuit breaker is sufficient to reconnect an islanded, highly unbalanced microgrid back to the utility grid. © 2014 Elsevier Ltd.

COLOMBO (Thomson Reuters Foundation) - An ambitious plan by the Sri Lankan government to outfit 100,000 homes with solar panels, to turn them into power producers for the national grid, may be too expensive for many families to afford, experts warn. Sri Lanka’s government this month launched a “battle for solar energy” that aims to add 220 megawatts of clean power to the country’s energy grid by 2020, or about 10 percent of the country’s current daily electricity demand. By 2025, the country hopes to boost its solar power output to 1,000 megawatts to meet fast-growing power needs, said President Maithripala Sirisena. The president, who launched the initiative, said the plan called for solar panels to supply all the energy needed at the president’s residence, and that the country was committed to meeting growing energy demand with clean energy. But shifting away from coal and other fossil fuel power to renewables – the country’s goal, according to Ranjith Siyambalapitiya, its power and energy minister – will be a challenge, the officials admitted. Solar power has the potential to meet 32 percent of Sri Lanka’s annual power demand of around 10,500 gigawatts – but so far just 0.01 percent of that potential has been developed, according to the Sri Lanka energy sector development plan for 2015-2025. Today about 3 percent of Sri Lanka’s energy demand is met by renewables such as wind and solar. Hydropower provides about half of the country’s electricity during the wet season but during the dry season, between August and October, 81 percent of the island's power needs are met by fossil fuels, over half of that from coal. "Solar is still not very popular because entry level costs are high and it does not make economic sense to low-end consumers," said Thusitha Sugathapala, an energy specialist at the University of Moratuwa. The cheapest entry-level home solar panel installation costs over 200,000 Sri Lanka rupees, or about $1,370. That’s because the materials must be imported, and face import duties, Sugathapala said. Even larger users of household power, by comparison, pay only around Rs 5,000 ($34) a month in electricity bills. Sugathapala, who previously worked on energy issues in the government, said household that use small amounts of electricity are also heavily subsidised by richer households. For the smallest-scale users, of 1 to 30 units of electricity a month, electricity costs Rs. 7.85 a unit, while large household consumers – those above 180 units - pay Rs. 45 per unit. The potential loss of that subsidy for poor households is one barrier to faster uptake of solar energy, Sugathapala said. Tharanga Dissanayake, a computer programmer whose household in Moratuwa, south of Colombo, uses an average of 200 units of electricity per month, said that investing several hundred thousands rupees on solar energy panels was not a smart option for him. “It would be at least four years before I recoup my investments. That is too long and I may have to spend on repairs,” he said. Under the current effort to promote household solar installation, the government has offered to buy electricity generated by household solar panels at about Rs. 22 per unit. The scheme also offers households low-interest bank loans to buy the equipment, with a repayment period of seven years. But experts like Sugathapala feel that more incentives will be needed to persuade families to shift to solar. "If we are to make solar attractive, then ideally there needs to be more attractive incentives,” he said, including things like cheaper costs for panels, free installation, government help in maintaining panels and a higher government payment for solar energy produced for the national grid. He said Sri Lanka has historically looked to the least expensive option to generate power, to hold down costs for consumers. Currently, because the cost of imported solar equipment is high and coal is relatively cheap, coal is the cheapest option – as long as issues like the environment and health aren’t taken into account. At current rates, a kilowatt of electricity generated using solar panels costs Rs 23 while an average coal-generated kilowatt costs Rs 15, according to Sugathapala and data from the Ceylon Electricity Board. Energy minister Siyambalapitiya said pressure to keep electricity prices low for consumers meant shifting to cleaner energy was unlikely to be cost-effective in the short run.
