This document discusses aggregate production planning, which involves determining optimal levels of key decision variables like production rate, inventory, and backordering over time to adjust for demand fluctuations within constraints. The planning horizon of one year for a case study company was divided into three periods. A mathematical goal programming model was formulated and solved using a computerized technique to obtain decision variable values for all planning periods. This would help the company optimally meet non-constant demand across periods and minimize total relevant costs.
This document is a dissertation submitted in partial fulfillment of a Master of Technology degree in Mechanical Engineering. It discusses using a goal programming approach to solve production planning problems in engineering industries. Goal programming is a mathematical optimization technique that is well-suited for solving multi-objective production planning problems. The dissertation formulates a production planning problem as a goal programming model and solves it using a computer-based simplex method. It analyzes the output to demonstrate how goal programming can effectively handle the complex trade-offs involved in production planning.

This chapter provides an expanded view of performance management that goes beyond the traditional I/O psychology focus on performance measurement. It discusses performance management as including what happens before and after performance is measured, considering the role of time and context. It also notes the divide between the topics academics research and those practitioners are interested in, with academics focusing more on measurement and practitioners more interested in talent management and leadership development. The chapter argues this divide needs to be addressed to better help practitioners implement research-based performance management.

This document presents a genetic algorithm approach for mission and safety planning with unmanned aerial vehicles (UAVs). It combines two existing genetic algorithm architectures - a hybrid genetic algorithm (HGA4m) for mission path planning and a multi-population genetic algorithm (MPGA4s) for replanning paths under critical situations. The proposed approach embeds both architectures into a single hardware system called MOSA (Mission Oriented Sensor Array) for mission supervision and IFA (In-Flight Awareness) for safety supervision. Computational results show the approach can find good solutions for both path planning and replanning within hardware limitations of onboard processors.

Distance learning has several advantages over traditional in-person learning including increased communication between students and instructors, easier collaboration between classmates, and more flexible post-course support. However, distance learning also faces challenges such as some students experiencing technology anxiety and the need for software to support dynamic data exchange across networks. Effective distance learning requires both students and instructors to have prior computer experience and technical support.
The document discusses the need to reform and improve vocational education in India. It notes that currently, vocational education makes up a small percentage of the education system and is not aligned well with industry needs. The document outlines several problems with the current system, including a lack of private sector involvement, rigid regulations, and few opportunities for career progression or skill upgrading. It also discusses government initiatives to establish a National Vocational Qualification Framework and compares vocational education frameworks in other countries like the UK, Australia, and China. The goal is to make recommendations to help introduce higher-quality vocational education programs in India.
The document lists 24 institutions and their vice chancellors who are confirmed participants in the Shastri Delegation of Vice Chancellors. The institutions include central universities, national law universities, IITs, IIMs and other prominent universities across India.
The document outlines 10 essential steps needed to improve higher education in India, which faces serious challenges from increasing student numbers and declining quality. These include: 1) conducting manpower planning to ensure relevant education and employment opportunities, 2) improving quality to rank Indian institutions globally in the top 100, 3) overhauling the examination system, 4) reforming administrative practices, 5) regulating the number of educational institutions, 6) promoting teaching as a respected profession, 7) increasing support for rural students, 8) fostering creativity and innovation, 9) enhancing collaboration, and 10) making India a provider of trained global manpower. It calls for an action-oriented roadmap to address these issues within the next 12 months.

Assessment and Planning in Educational technology.pptxKavitha Krishnan
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
