In this work, minimum energy based interpolation has been done for an optimal well path and effects of energy and fitting coefficients have been studied. An optimal well path also maintains the given radius of curvature and satisfies drilling requirements. Interactive incremental design concept has been used in this work which, controls length and other geometric properties of well path. In the first part of the research, whole well segment has been taken for optimization. Geometric constraints are put to satisfy the drilling requirements. In the second part of the research only the curved portion of well segment has been taken for optimization. Geometric perspective of the well has been considered in this formulation.

The purpose of this paper is to determine the heat transfer and fluid flow characteristics of an internally finned tube for different flow conditions.

Numerical investigation have been performed by solving the conservation equations of mass, momentum, energy with two equation-based k-eps model to determine the wall temperature, outlet temperature and Nusselt number of an internally finned tube.

It has been found from the numerically investigation that there exists an optimum fin height and fin number for maximum heat transfer. It was also found that the heat transfer in T-shaped fin was highest compared to other shape. The saw type fins had a higher heat transfer rate compared to the plane rectangular fins having same surface area and the heat transfer rate was increasing with teeth number. Keeping the surface area constant, the shape of the duct was changed from cylindrical to other shape and it was found that the heat transfer was highest for frustum shape compared to other shape.

The present computations could be used to predict the heat transfer and fluid flow characteristics of an internal finned tube specifically used in chemical and power plants.

The original contribution of the paper was in the use of the two equation-based k-eps turbulent model to predict the maximum heat transfer through optimum design of fins and duct.

This study presents the development of a supply chain (SC) observatory, which is a benchmarking solution to support companies within the same industry in understanding their positioning in terms of SC performance.

A case study is used to demonstrate the set-up of the observatory. Twelve experts on automatic equipment for the wrapping and packaging industry were asked to select a set of performance criteria taken from the literature and evaluate their importance for the chosen industry using multi-criteria decision-making (MCDM) techniques. To handle the high number of criteria without requiring a high amount of time-consuming effort from decision-makers (DMs), five subjective, parsimonious methods for criteria weighting are applied and compared.

A benchmarking methodology is presented and discussed, aimed at DMs in the considered industry. Ten companies were ranked with regard to SC performance. The ranking solution of the companies was on average robust since the general structure of the ranking was very similar for all five weighting methodologies, though simplified-analytic hierarchy process (AHP) was the method with the greatest ability to discriminate between the criteria of importance and was considered faster to carry out and more quickly understood by the decision-makers.

Developing an SC observatory usually requires managing a large number of alternatives and criteria. The developed methodology uses parsimonious weighting methods, providing DMs with an easy-to-use and time-saving tool. A future research step will be to complete the methodology by defining the minimum variation required for one or more criteria to reach a specific position in the ranking through the implementation of a post-fact analysis.

Strategy.

The case can primarily be used for a Strategic Management course for teaching the revival strategies for financially weak plants. The case highlights the need to shift from a product manufacturing perspective to a market orientation perspective and, hence, may add value as an add-on case in a Strategic Marketing course. The case also covers the topic of benchmarking which may be of use in an Operations Management course.

DJSL Ltd. is the largest engineering and manufacturing enterprise in India in the energy-related/infrastructure space in the public sector. Its Lucknow unit, manufacturing porcelain insulators and wear resistant ceramic lining (CERA LINING), has started reporting losses. A change of management took place in October 2015, whereby Mr. S P Singh was appointed as the Head of the Lucknow Unit. Mr. Singh had rich functional experience of 30 years, mainly in the domains of strategy, project execution and commercial aspects. He was asked to come up with a revival plan for the Unit by the top management of DJSL. The case highlights the importance of operational issues in turnaround management.

Students may be encouraged to debate the benchmarking practices that are best suited for the Lucknow unit. They can also discuss the impact of benchmarking efforts upon turnaround strategy. Students are also encouraged to understand the constraints which may limit the success of initiatives impacting operational improvements. Students need to develop the understanding of marketing strategy to perform a SWOT analysis of each product of the Lucknow unit and to sense the business opportunities in and around the environment. Students need to discuss how productivity may be improved with the adoption of appropriate people development strategies. Students are encouraged to discuss the revival/turnaround strategies and to identify the influence of improvement in operational efficiency/productivity upon revival plan.

CSS: 11: Strategy.

The case is intended to be used by post-graduate students of Management in the courses of Marketing Management and New Product Management. This case may also be used in other courses like Consumer Behaviour and Strategic Marketing.

Indian fast-moving consumer goods (FMCG) sector set to reach an astonishing INR165.62 trillion (US$3.6 trillion) by 2012 gave a tremendous opportunity to Hindustan Unilever Limited (HUL) to establish its footprint in all consumer packaged products. Dove, a brand of HUL, primarily catering to the premium segment of the market, launched Dove Elixir Hair Oil in November 2012 priced at INR185 (US$3.41) for 90 ml. This was five times higher than any other light hair oil in the market. The case brings out facts that describe market situations at that time and questions if a substantial market at higher end, for Dove hair oil, was available.

This case has been documented to help students understand the concept and applicability of brand extension strategy. The students shall learn the dynamics of this strategy in the market by answering the following questions: What are the factors that contributed to the growth of FMCG market in India? Evaluate HUL's decision to extend the brand Dove into other product categories? Was the market for Dove hair oil available at the higher end? What strategies should Dove use for its hair oil?

Increasing trends of climatic risk pose challenges to the food security and livelihoods of smallholders in vulnerable regions, where farmers often face loss of the entire crop, pushing farmers (mostly men) out of agriculture in destitution, creating a situation of agricultural making agriculture highly feminization and compelling male farmers to out-migrate. Climate-smart agricultural practices (CSAPs) are promoted to cope with climatic risks. This study aims to assess how knowledge related to CSAPs, male out-migration, education and income contribute to the determinants of male out-migration and CSAPs adoption and how they respond to household food security.

Sex-disaggregated primary data were collected from adopter and non-adopter farm families. STATA 13.1 was used to perform principle component analysis to construct knowledge, yield and income indices.

Yield and income index of adopters was higher for men than women. The probability of out-migration reduced by 21% with adoption of CSAPs. An increase in female literacy by 1 unit reduces log of odds to migrate by 0.37. With every unit increase in knowledge index, increase in log-odds of CSAPs adoption was 1.57. Male:female knowledge gap was less among adopters. Non-adopters tended to reduce food consumption when faced with climatic risks significantly, and the probability of migration increased by 50% with a one-unit fall in the nutrition level, thus compelling women to work more in agriculture. Gender-equitable enhancement of CSAP knowledge is, therefore, key to safeguarding sustainable farming systems and improving livelihoods.

The enhancement of gender equitable knowledge on CSAPs is key to safeguard sustainable farming systems and improved livelihoods.

This study is based on the robust data sets of 100 each of male and female from 100 households (n = 200) using well-designed and validated survey instrument. From 10 randomly selected climate-smart villages in Samastipur and Vaishali districts of Bihar, India, together with focus group discussions, the primary data were collected by interviewing both men and women from the same household.

Food manufacturing supply chain systems are the most relevant wheels of the world economy since they provide essential products supporting daily life. Nevertheless, various supply inefficiencies have been reported to compromise food safety in different regions. Sustainable supplier management and digitalization practices have become cornerstone activities in addressing these shortcomings. Therefore, this paper proposes an integrated method for sustainability management in digital manufacturing supply chain systems (DMSCS) from the food industry.

The Intuitionistic Fuzzy Analytic Hierarchy Process (IF-AHP) was used to weigh the criteria and subcriteria under uncertainty. Second, the Intuitionistic Fuzzy Decision-Making Trial and Evaluation Laboratory (IF-DEMATEL) was applied to determine the main DMSCS sustainability drivers whilst incorporating the expert's hesitancy. Finally, the Combined Compromise Solution (CoCoSo) was implemented to pinpoint the weaknesses hindering DMSCS sustainability. A case study from the pork supply chain was presented to validate this method.

The most important criterion for DMSCS sustainability management is “location” while “manufacturing capacity” is the most significant dispatcher.

This paper presents a novel approach integrating IF-AHP, IF-DEMATEL, and CoCoSo methods for sustainability management of DMSCS pillaring the food industry.

To study the situation of alcohol relapse and to investigate the relationship between psychological factors and alcohol relapse in persons with alcohol dependence in Thai Nguyen hospitals, Vietnam.

A correlation study was conducted among 110 patients. Data were collected through structured interviews and were analyzed using descriptive statistics and Spearman's correlation coefficient (r_s).

More than two-thirds of the participants were found to relapse more than once (X¯ = 2.04, SD = 0.86). Positive outcome expectancies, cravings, negative emotional states, and maladaptive coping were positively associated with relapse (r_s = 0.550, 0.522, 0.497; p = 0.000 and r_s = 0.217, p < 0.05, respectively). While, motivation to change with three subscales had a negative correlation to relapse including recognition (r_s = −0.199, p < 0.05), ambivalence (r_s = −0.331, p = 0.000), and taking steps (r_s = −0.606, p = 0.000). Adaptive coping, self-efficacy, and social support were also found to be negatively correlated to relapse (r_s = −0.535, −0.499, −0.338; p = 0.000, respectively). However, negative outcome expectancies (r_s = −0.024, p = 0.805) and positive emotional states (r_s = 0.081, p = 0.399) were not significantly related to relapse.

The findings of this study are significant implications for relapse prevention strategies. It suggests that the essential parts of relapse prevention are through: changing alcohol expectations, increase drinking refusal self-efficacy, coping skills training, enhancing motivation to change, managing alcohol craving and expanding social support.

This is the first study in Vietnam which investigated the relationship between psychological factors and alcohol relapse in individuals with alcohol dependence.
