Through the application of learning analytics and educational data mining, a large dataset of 1039 students was analyzed to gain insights into factors leading to a successful examination.

In the event of disruptions such as machine failure, the original flow-shop schedule needs to be revised and/or rescheduled. In such a scenario, rescheduling methods based on right-shift rescheduling and affected operations rescheduling work very well. Here in this study, the deviation of the make-span of the revised schedule from the original schedule is used as a performance measure. We have proposed three rescheduling methods. There are multiple factors that influence the performance of the rescheduling methodology. One of them is the make-span deviation of the schedule, and the factors influencing it are optimality of the initial solution, failure duration, deviation of make-span, rescheduling method, size, and instant of failure. The initial schedule and problem size depend on the flow-shop manufacturing system for which scheduling is perf...

Supply chain ensures improved efficiency and effectiveness of not only product transfer, but also information sharing between the complex hierarchies of all the tiers. The literature on SCM that deals with strategies and technologies for effectively managing a supply chain is quite vast. In recent years, organizational performance measurement (PM) and metrics have received much attention from researchers and practitioners. Performance measurement and metrics have an important role to play in setting objectives, evaluating performance, and determining future courses of actions. Performance measurement and metrics pertaining to SCM have not received adequate attention from researchers or practitioners. There is no systematic grouping of the different performance measures in the existing literature. The development of a framework for PM in supply chains requires generalised performance measures. This paper seeks to provide an extensive literature review for identification of performance measures, which in turn forms a basis for establishing a framework for performance measurements in supply chains.

After a set of processes has been selected for all the features of part, the sequencing task begins by searching and analysing relationship between features. This is done by rule to detect geometrical interactions and the appropriate precedence relationship in knowledge base. For deciding sequence of operations precedence relationship among the different operations is developed using decision rules. CNC program is generated based on the process plan of a given component. The generated CNC program is then validated by simulation software before giving it to CNC machine.

The literature on SCM that deals with strategies and technologies for effectively managing a supply chain is quite vast. In recent years, organizational performance measurement (PM) and metrics have received much attention from researchers and practitioners. Performance measurement and metrics have an important role to play in setting objectives, evaluating performance, and determining future courses of actions. Apart from the common criteria such as cost and quality, ten other performance measurements are defined, visibility, trust, innovativeness, delivery reliability, flexibility and responsiveness, resource utilization, cost, assets, technological capability, service and time to market, so total twelve criteria and fifty eight subcriteria are used to evaluate the performance in supply chain. So, for evaluating and selecting supplier a multi-attribute decision-making technique, an analytic hierarchy process (AHP), is used to make decision based on the priority of performance measures. This paper describes a decision framework for evaluating and selecting supplier performance in a supply chain. A case study from the automotive industry is used to demonstrate the AHP technique.

It can improve efficiency and effectiveness of product transfer and information sharing between complex hierarchies of all the tiers. Supplier selection is an important step in the supply chain design. In many existing decision models for supplier selection, only quantitative criteria are considered. However, supplier selection is a multi-objective problem containing quantitative as well as qualitative factors. It is difficult to map human perception to particular number or a ratio due to vagueness in the decision making process. Fuzzy Analytic Hierarchy Process (FAHP) therefore helps the decision makers to deal with imprecision and subjectiveness in pair-wise comparison process. This study aims to provide a systematic approach towards the application of FAHP to supplier selection problem. FAHP is applied to find the importance degree of each criterion as the measurable indices of the supplier. From an extensive analysis of the results, it is observed that selection of an appropriate supplier would result in improving effectiveness of supply chain. Thus, the overall rank ordering of alternatives as identified by fuzzy AHP seems reasonable and consistent with managerial preferences and judgments.

Moreover, microscopic examination of cross section of work samples eroded by AJM shows that, for brittle materials, material removal is due to intersection and propagation of cracks produced by adjacent impacting particles on target surface. An analytical model has been developed based on the above observations for predicting the material removal in abrasive jet machining process. The model also suggests the critical value of mass flow rate which has been substantiated experimentally. In addition, the influence of velocity and mass flow rate of abrasive particles on material removal rate is briefly described.

Most traditional cell formation procedures ignore any changes in demand over time caused by product redesign and uncertainties due to volume variation, part mix variation, and resource unreliability. However in today's business environment product life cycles are short, volumes and product mix can vary frequently. Thus cell design needs to address these issues. In this paper, Dynamic Cellular Manufacturing Systems (DCMS), Virtual Cellular Manufacturing Systems (VCMS) and Hybrid Cell Layout are discussed along with CMS. Based on the CMS methodologies, classification and comparison few suggestions are presented regarding possible future research directions for the CMS problem for both newly and already established researchers.
