Product Mix Optimization and System Analysis Using The Theory of Constraints Approach

Paper ID- AMA-09-04-2022-11293

The Theory of Constraints is a crucial management discipline that argues there is at least one limited resource in each production system, and a solution should be found to overcome this limited resource in order to increase the market share and profitability of firms. As the bottleneck in the system is identified and managed, production will occur on time and be available to the customer, since delays in the production process will be eliminated. Moreover, costs will be reduced as the efficiency at the bottleneck in the production line is improved, and thus the company can reach its profitability targets. The aim of this study is to determine the optimum product mix under the presence of limited resources in the system with the five-step continuous improvement process of the Theory of Constraints. Within this framework, research has been conducted to solve multiple bottleneck problems in a company operating in the metal processing industry. In this application, by analyzing the capacity utilization rates of the resources, the resources at the bottleneck in the system were identified and the optimal product mix was determined. As there is no throughput priority or mathematical method to production of subcomponents in current process, a new algorithm was proposed which is integrating the linear programming and fuzzy logic methodology with the theory of constraints approach. The problem was defined as an integer linear programming model and solved by an optimization software program called GAMS IDE.

Mechanization in Maize crop cultivation in Telangana, India - Energy Efficiency Indices and productivity

Paper ID- AMA-09-04-2022-11292

The field experiment and demonstrations were conducted at Agricultural Research Station, Karimnagar and in farmers fields in different mandals of Karimnagar district, Telangana, India from 2017-18 to 2019-20 on Mechanization in maize crop cultivation versus conventional /farmers method of cultivation to study various energy inputs and output energy equivalents, efficiency and productivity. The study consisted of two treatments 1.Conventional method 2.Mechanization in maize cultivation for sowing, spraying, harvesting and threshing operations. The results revealed that Cultivation of maize by mechanization requires significantly less input energy (36651 MJha-1) than compared to conventional farmers practice (37825 MJ ha-1) because of less labour usage under mechanization. The output energy in mechanized method of maize cultivation is significantly less (108089 MJ ha-1) over conventional farmers practice (122537 MJ ha-1) as energy accumulation in mechanization is only from grain yield, While in conventional method both grain and stalk yield contribute to significantly higher output energy and inturn higher net energy (84712 MJ ha-1). However energy efficiency and energy profitability is statistically on par in both methods of maize cultivation. The energy productivity (0.200 Kg ha-1) and energy intensity in economic terms (1.33 MJ Rs. -1) with mechanized method of maize cultivation resulted higher than conventional method indicating energy efficient sustainable production system with advantages of saving of labour mandays, reduction of cost of operation and time over conventional method of maize cultivation.

Assessment of Genetic Variability, Heritability and Genetic Advance of Okra Genotypes (Abelmoschus esculentus L. Moench)

Paper ID- AMA-08-04-2022-11291

The experiment was performed in Randomized Complete Block Design (RCBD) with three replications and germplasm evaluated at Vegetable Research Farm, Kalyanpur, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (Uttar Pradesh) during Kharif season of 2018-19. Analysis of variance revealed significant variability among the strains of okra for all character’s studied. Heritability estimates varied from (60.80%) for length of fruits to (99.70%) for number of seeds per fruit. It was partitioned as very high (above 90%), high (70- 90%), medium (50-70%) and low (less than 50%).heritability estimates were observed very high for number of seeds per fruit (99.70%), days to 50% flowering (99.0%), yield per plant (98.80%), number of fruits per plant (98.50%) and plant height at 45 days. High for diameter of fruit (89.20%), first flowering node (88.30%), Plant height at 90 days. Medium estimation of heritability was recorded for length of fruits. Phenotypic variances range between days to first flowering (4.67) and plant height at 45 days (20.08) The phenotypic coefficient of variations was highest for characters viz., plant height at 45 days (20.08%), number of fruits per plant (17.37%), and number of seeds per fruit (17.34%). and genotypic variances ranging between days to first flowering (4.63) and plant height at 45 days (19.79). High genotypic coefficient of variation was noted for plant height at 45 days (19.79%), number of seeds per fruit (17.38), number of fruits per plant (17.24%) and plant height at 90 days (15.56%). Genetic advance expressed as percent of mean was high (>20%) for plant height at 45 days (40.18), no of seeds per fruits (35.63), number of fruits per plant (35.25), plant height at 90 days (29.94), fruit yield per plant (27.97), diameter of fruits (27.55) and first flowering node (21.87). While the moderate genetic advance (<20 to 10%) was observed for fruit length (15.5) and days to 50% flowering (10.5).

Findings of cartap hydrochloride alternative to the monocrotophos against coconut black headed caterpillar, Opisina arenosella (Walker) using syringe method in coconut palm

Paper ID- AMA-08-04-2022-11290

The present study was conducted at Halebudanur village in Mandya district in Karnataka, India. The syringe method, a novel approach of insecticide administration into the coconut palm was applied using an eco-friendly, animal originated insecticide cartap hydrochloride 50% SP for the management of coconut black headed caterpillar, Opisina arenosella. The results of the study found that, all dilution of cartap hydrochloride 50% SP injected to base of the coconut palm effectively achieved 100% larval mortality of O. arenosella and protection lasted up to 90 days with no phytotoxic symptoms to the leaflets of treated palms. The syringe method has revealed quicker absorption of insecticides, easy to implement and no secondary infection or mechanical damage to the palm tissues and can be useful in coconut palm in managing O. arenosella population.

ICT in Agricultural Higher Education: Investigating the flowers and flaws

Paper ID- AMA-08-04-2022-11289

This study aimed to determine the impact of digital technologies on agricultural graduates of Indian State Agricultural Universities. An investigation into the effects of digital tools on academic development with the students was conducted. The sample consisted of 1438 undergraduate students and 327 faculty members belonging to ten State Agricultural Universities of India comprising twenty diverse agricultural sciences colleges selected through the Simple Random Sampling method. Data were collected with the help of a semi-structured interview schedule developed for the purpose, along with informal observation and discussions. The students under study agreed on the impact of ICTs in saving time, giving accurate information, easing the exchange of ideas, and keeping up-to-date information. Though ICTs are supposed to be associated with a positive impact, there are still some negative impacts of ICT as perceived by the students. Most of the students linked ICT with health problems/lack of physical activity, reduced personal interaction and a threat to security and privacy. Students are reluctant to attend classes, insufficient use of the library, wastage of time in net surfing, over-dependence on ICT, social media distraction, spurious information, duplication of research and critical reading and writing skills of students To attract students to attend classes, blended learning and innovative ICT methodologies should be used apart from PowerPoint Presentations.
