Rolling Ingot

To improve productivity and profitability in Aluminium continuous casting industry the main action is to reduce losses due to defects resulting into revenue losses. Improving Rolling Ingot Recovery is possible by reducing the rejections & using the resources effectively (resources MAN, MACHINE, MATERIAL & CAPITAL) by applying TQM technique. This study presents a case about minimizing defects in aluminium continuous casting using Total Quality Management (TQM) techniques in which why-why analysis, Standard Operating Procedures (SOPs),and Cause and Effect analysis is used. It can be concluded from study that rejections, shell zone & inclusion can be reduced by, Continuous monitoring the health of the moulds, quality & quantity of water, the metal casting temperature, metal head in mould, water impingement angle, use of Ceramic foam filter plates, awareness & the adherence towards the guidelines

Remanufacturing has gained attention from industry, but the literature lacks the scientific comprehension to realize efficient remanufacturing. This hinders a company from commencing or improving remanufacturing efficiently. To fill this gap, the paper proposes a set of practical success factors for remanufacturing. To do so, it analyzes remanufacturing practices in industry through interviews with staff from remanufacturing companies with long experience. The practical success factors are found to be (1) addressing product and component value, (2) having a customer-oriented operation, (3) having an efficient core acquisition, (4) obtaining the correct information, and (5) having the right staff competence. Next, the paper further analyzes remanufacturing processes theoretically with both cause and effect analysis and means-ends analysis. Since the factors show that, among other things, the product/service system (PSS) is highly relevant to remanufacturing in multiple ways, theories on the PSS are partly utilized. As a result, the distinctive nature of remanufacturing underlying in the processes is found to have high variability, high uncertainty and, thus, also complexity. The obtained insights from practice and theory are found to support each other. In addition, a fishbone diagram for remanufacturing is proposed based on the analysis, including seven m's, adding two new m's (marketing and maintenance) on top of the traditional five m's (measurement, material, human, method, and machine) in order to improve customer value. The major contribution of the paper lies in its insights, which are grounded in both theory and practice.

Sustainable office building indoor environment design is a challengeable issue for professionals in thermal comfort, satisfaction, health, and energy fields of research. The professionals intensively need a comprehensive list of office indoor environment design features to promote the level of performance and productivity of staff. One of the most effective factors dealing with staff performance and productivity is physical and psychological health which has not yet been investigated in depth is open-plan office design. In this regard, the current research aimed at establishing a comprehensive list of Open Plan Offices Design (OPOD) features affecting physical and psychological health and well-being of the staff at office buildings. Research methodology engaged two phases corresponding to two objectives. Phase one was to investigate OPOD features and sub-features through a critical literature review using fishbone cause-and-effect analysis technique. Phase one has clustered the OPOD features into two; positive and negative classes. The cause-and-effect analysis determined 3 positive features and 5 negative features involved in the positive and negative classes, respectively. The Efficient Workflow and Performance, Flexible Design, and Cost Efficient were identified as positive OPOD features which involves a number of sub-features. The Distraction, Decreasing Work Feedback, Job Dissatisfaction, Illness, and stress have been determined as OPOD features which impact negatively on staff’s health. The second phase conducted a content analysis on reviewed literatures to indicate the popularity of citation of each OPOD feature in previous studies. The content analysis determined in the Positive cluster, the sub-feature “Facilitate Communication”, under Efficient Workflow & Performance was investigated more than other sub-features. In addition, in the Negative cluster, the sub-feature Auditory Distraction under Distraction was highly investigated. The research asserts that undertaking the research outputs will promote performance and productivity of staff in office buildings. Architects, facility managers, design consultants, and authority may use the output as a decision support checklist for future office design and/or renovations.

Cause And Effect Analysis

Sustainability is a growing concern for manufacturing companies, as they are major contributors to pollution and consume a substantial portion of the world´s natural resources. Sustainable manufacturing can reduce waste, conserve energy and increase resource efficiency. However, one of the main challenges facing manufacturing organisations to put sustainability into practice is the lack of understanding of the cause-and-effect relationships between critical indicators of sustainable manufacturing. To overcome this challenge, a novel, rigorous and integrated framework, composed of four quantitative methods, is proposed to analyse critical indicators of sustainable manufacturing. The analysis is based on responses from both academic and industry experts. These four methods including DEMATEL (decision-making trial and evaluation laboratory), the MMDE (maximum mean de-entropy) algorithm, ISM (interpretive structural modelling) and SEM (structural equation modelling) are uniquely integrated to present statistically validated relationships between critical indicators using information on varying degrees of relationship between them. The final cause-and-effect models for the respondent groups (i.e., researchers and industry experts) are further validated through gathering the viewpoints of a researcher and an industry practitioner for its robustness. The novelty of our research lies in: (1) proposing a novel and integrated rigorous quantitative framework combined with qualitative research method; (2) applying the proposed framework to analyse contextual relationships between critical indicators of implementing sustainability, in the manufacturing sector as a whole, which to the best of authors’ knowledge is the first of its kind; and (3) comparing and contrasting results of researchers and industry practitioners’ groups along with a check of their validation and robustness.

This paper analyses factors that might cause accidents to the container ships due to containers stacked on deck, and propose applicable actions to minimize these factors. The number, capacity, and speed of hatch-coverless container ships worldwide have increased significantly since the latest decade due to the increase of world trade. There is also a trend of stacking more containers on deck in order to increase the capacity of the ships. This phenomenon makes the number of container ship accidents also increasing; particularly capsize or sink. Even though merchant ships have to comply with safety rules and regulations, but the number of accidents still significantly high. The accidents usually cause great loses to the cargo and damage the overall logistic system. The sources of container ship accidents can be categorized into the ship itself, the environment, human factor, and management. In this study, accidents data and related information were gathered through literature study, on the spot observation, and direct interviews with relevant parties. Causes of accidents were then identified using cause and effect analysis. Based on the findings from the analysis, options for overcoming them were simulated to obtain the most applicable solutions that would minimize the accidents.
