Lean Manufacturing can be considered as a business strategy which was originated and developed in Japan. It tries to identify waste and eliminate it. Thus it leads to improvement in productivity and quality and companies can achieve a competitive advantage over others. Sri Lankan industries, especially apparel sector have attempted to implement this, but a little research work is carried out in regarding its suitability. This research is an attempt to identify a suitable Lean model for the apparel industry in Sri Lanka. As the initial stage of this study, a literature review is carried out to study about the Lean Manufacturing. It starts by looking at how Lean Manufacturing first began. Then it seeks to identify the core principles, tools and techniques and how those tools and techniques are currently being used worldwide. After studying the global scenario the next step is to look at the Sri Lankan context using real world data. This was undertaken by means of structured surveys, observations, and on site interviews. Also the study will reveal period of Lean implementation, suitable implementation methods, order of implementation, tools which are avoided, sustainability of different tools, challenges faced, ways of overcoming challenges and benefits achieved after applying Lean Manufacturing concepts in the apparel sector of Sri Lanka. The findings state Lean Manufacturing can be applied to mass production apparel industries and has created a positive mindset on employees. As implementation of Lean concepts is still in developmental stage, the full benefit is not yet achieved. But current situation suggests that the industry can go forward with Lean and capitalize on its full potential. In this research the authors have proposed a model which can be used to implement Lean in a systematic manner and each manufacturer must develop their own Lean system through training, experiments, employee empowerment, right leadership and kaizen mindset. Originality of the research— The research builds up a Lean Model which is not yet developed for the apparel sector in Sri Lanka. It can be further modified to suit the global apparel industry and other industries as well.

Abstract This paper prepared for 2018 OTC Offshore Asia explores the current history of electrically driven functionality for subsea production systems. It is expected that co-existence of hybrid electrohydraulic and all-electric functionality will dominate the market for subsea tree and manifold control short term. Electric choke and manifold valve actuation offer many advantages as proved successfully during the last 16 years, e.g. related to modularity and flexibility, with zero discharge, with high operational speed and high positioning accuracy, along with CAPEX and OPEX benefits. Performance of systems such as Statoil's Asgard Subsea Gas Compressor is a game changer that will make all-electric valve control base case also for future subsea processing plants. Reliability & Availability concerns were the major concerns by many operators for not switching to all-electric technology. The excellent reliability of trickle charged batteries in subsea systems, combined with modern safety electronics eliminate the traditional actuator spring as failsafe mechanism power source. All of this has simplified the equipment, reduced the size, and enables continuous equipment status monitoring. Competitive all-electric systems are expected to be introduced in stages, starting with infill wells. This will eliminate the risk of new technology for the best business cases, being long distance gas fields, water injectors and deep water systems. Subsea all-electric solutions benefit from general technology developments in other industries. Full utilization is however slow in the subsea market, hampered by current rules and regulations, risk aspects and conservative mindsets. All-electric solutions need Champions and a continued successful staged development initiatives to realize their full potential for significantly reducing subsea field development capital and operational cost.

Growing consumerism and population worldwide raises concerns about society’s sustainability aspirations. This has led to calls for concerted efforts to shift from the linear economy to a circular economy (CE), which are gaining momentum globally. CE approaches lead to a zero-waste scenario of economic growth and sustainable development. These approaches are based on semi-scientific and empirical concepts with technologies enabling 3Rs (reduce, reuse, recycle) and 6Rs (reuse, recycle, redesign, remanufacture, reduce, recover). Studies estimate that the transition to a CE would save the world in excess of a trillion dollars annually while creating new jobs, business opportunities and economic growth. The emerging industrial revolution will enhance the symbiotic pursuit of new technologies and CE to transform extant production systems and business models for sustainability. This article examines the trends, availability and readiness of fourth industrial revolution (4IR or industry 4.0) technologies (for example, Internet of Things [IoT], artificial intelligence [AI] and nanotechnology) to support and promote CE transitions within the higher education institutional context. Furthermore, it elucidates the role of universities as living laboratories for experimenting the utility of industry 4.0 technologies in driving the shift towards CE futures. The article concludes that universities should play a pivotal role in engendering CE transitions.
