Decision making for supermarket food purchase decisions are characterized by network relationships. This paper analyzed factors that influence supermarket food selection and proposes a supplier evaluation index system based on the whole process of food production. The author established the intuitive interval value fuzzy set evaluation model based on characteristics of the network relationship ...

Most of data in Multi-attribute decision making (MADM) problems are changeable rather than constant and stable. Therefore, sensitivity analysis after problem solving can effectively contribute to making accurate decisions. In this paper, we offer a new method for sensitivity analysis in multi-attribute decision making problems in which if the weights of one attribute changes, then we can dete...

We propose a clustering framework that supports clustering of datasets with mixed attribute type (numerical, categorical), while minimizing information loss during clustering. Real world datasets such as medical datasets and its ontology have mixed attribute type datasets. However, most conventional clustering algorithms have been designed and applied to datasets containing only single attribut...

In this report, we first discuss the modeling context that is suitable for the multi-attribute negotiations in the Navy detailing process. Then, we present the model based on a novel negotiation protocol for automated multi-attribute negotiations. The negotiation algorithm, negotiation strategies and the mediator’s problem are included in this model. Based on the discussions in this report, we ...

A functional dependency describes the relationship between attributes in a database relation. It states that the value of an attribute is uniquely determined by the values of some other attributes. It serves as a constraint between the attributes and is being used in the normalization process of relational database design. Therefore the discovery of functional dependencies from databases has be...

Stigma is considered to be a social process that gives a mark or attribute to individuals and is characterised by exclusion, rejection, blame or devaluation. Goffman defined stigma as an “attribute that is deeply discrediting and that reduces the bearer from a whole and usual person to a tainted, discounted one”. 1 Considering the literature, it can be clearly seen that patient groups with AIDS...

Purpose This research investigates when and how brands influence attribute importance weights. Most past studies modelling consumer decision processes treated the brand of a product as an parallel to price, color or size product, result, those assigned equal (i.e. non-contingent) weight across for each attribute. In contrast, this study introduces brand-contingent attribute-weighting process, i...

The material and manufacturing process selection problem is a multi-attribute decision making problem. These decisions are made during the preliminary design stages in an environment characterized by imprecise and uncertain requirements, parameters, and relationships. Material and process selection decisions must occur before design for manufacturing can begin. This paper describes a prototype ...

Data classification is a process which groups objects with common properties into classes and produces a classification scheme over a set of data objects. Data classification is useful for understanding and organizing database data and building hierarchical schemes in databases. We investigate data classification in relational databases and develop a method for data classification by concept-ba...
