In  white box classification techniques are used to predict the dropouts. Decision trees and rules induction algorithms and evolutionary algorithms are mainly used as the “white box” classification techniques. White box classification algorithms obtain models that can explain their predictions at a higher level of abstraction by IF-THEN rules. A decision tree is a set of conditions organized in a hierarchical structure. An instance can be classified by following the path of satisfied conditions from the root of the tree until a leaf is reached, which corresponds to a class label.
It is basically a graphical representation of what is going on in a process. It is a graphical tool used to distinguish between inherent & assignable variation. The SPC system incorporates the control chart with center line, upper limit, & lower limit functions which can be manipulated by the user. The control chart basically shows changes in data pattern as well as the causes of the changes in data. The control charts have a center line, upper limit line & lower limit line.
This pattern, represents an episode. It is similarly learnt as weight adjustments on the connections between F2 layer and selected category of F3 layer. An episode can be recognized based on the selected node in F3 layer and can be reproduced by a readout process. The corresponding events can be read out from F2 to F1 layer. Thus encoding, storing and retrieval of events is performed based on computational principles and
High quality and low quality companies have unexpected cost curves and they do not have the same minimum efficient scale. This causes to the alteration of outcomes which the low quality firms can be working at Minimum Efficient Scale which is appropriate to their quality level. In contrast, high quality companies still assumed to achieve Minimum Efficient Scale even though they are much bigger than low quality companies and operate in the same entire
So could supplies, orders, or cash. Constraints control output whether we acknowledge them or not. When properly recognized and managed, constraints can provide the fastest route to the significant improvement and form the foundation for constant growth. When organization ignored it, the constraint may lie idle, wasting large amounts of company’s capacity. A loss control constraint may also cause disorder on delivery schedules and cause unexpected delays.
Association Rule Learning (Dependency modeling) is a method that describes associated features in data, searching for relationships between variables. As an example, Web pages that are accessed together can be identified by association analysis. Anomaly Detection (Outlier/change/deviation detection), this class identifies anomalies or outlier data records which cause errors, or might be of interest and requires further investigation. Another class is Clustering, which is the task to discover groups and structures in the data which in some aspect is “similar” or “dissimilar”, without using known structures in the data And the last class, Summarization, attempts to provide a more compact representation of the data set, including visualization and report
This led to the difficulty in deciding which product process was appropriate, jobbing or mass process. Moreover, vague goal also resulted in unclear kind of customers, so it would make some obstacles determining the product portfolio, leading the surplus due to wrong anticipation. Therefore, inventory would increase, costing more expense of storing.
When considering the varying application of technology in the workplace, the middle and lower skill roles remain subject to the most replacement. Their routine information processing, calculations, and decision making make them the most susceptible in the advent of cheap, powerful computers and greater access to data (Gibbs 5). Labor market polarization is creating a gap in job availability between lower and middle skill tasks against those of higher skill sets; however, the question remains as to how job availability may shift as a result of automation. While “manufacturers operating in a high-wage country commonly seek to reduce cost through large automated equipment,” a high utilization of such methods makes it impossible to synchronize production with demand (Ketokivi et al. 2).
A. Problem Formulation In preparing this paper, various statements related to the major problem are constructed on succeeding problem formulations: in doing a business, several firms start from preparing resources, including IT resources, afterward, they organize those resources in order to achieve a superior performance. Nevertheless, to do the business, a firm can also begin from determining required performance in terms of planning the resources with the intention of accomplishing a cost advantage, which is one of the categories of competitive advantages . However, the firms occasionally have not paid attention to the cost efficiency resulting in a waste of resources. In other words, the process of value engineering, namely the acquisition
Because of lack of experience of the personnel. It may result in low output at higher cost. 2. Labour inefficiency : When a firm expands it production capacity , work areas may became more crowded leaving little space for each worker to work efficiently , moreover over specialization and division of labour creates over dependence on workers. Which increase the long run average cost of
