This paper proposes a new method to address a three-dimensional concurrent engineering (3D-CE) approach. It uses a Multi-Objective Linear Programming (MOLP) model integrated to the TOPSIS method in order to determine the best configuration product design, assembly process and suppliers of components. This method is able to involve various supply chain strategies by considering qualitative and q...

Service quality is widely taken as a driver of firms' marketing and financial performance. Evaluating service satisfaction is a multi-criterion decision problem which includes both qualitative and quantitative factors, and it needs more critical analysis. The aim of this paper is to identify and discuss some of the important and critical decision criteria for service satisfaction measurement ba...

We compare two methods regarding the factorization problem of binary, triadic, real and fuzzy data, namely Hierarchical Classes Analysis and the formal concept analytical approach to Factor Analysis. Both methods search for the smallest set of hidden variables, called factors, to reduce the dimensionality of the attribute space which describes the objects without losing any information. First, ...

Seawater desalination plants have been utilized to supply fresh water to the State of Kuwait since the early 50’s. In spite of the fact that there are several types of desalination technology that can be used more efficiently and economically, one type of desalination technology, namely multi-stage flash (MSF), has been used extensively in Kuwait. This work is an attempt to identify the most su...

Enterprise resource planning (ERP) systems are very costly and difficult to be implemented. Organizations need to be ready for implementing them. They require assessing their current readiness and then, they can perform a range of activities to improve their readiness. The ERP readiness is influenced by many factors which are interrelated and any improvement in one of them has direct and indire...

With the advent of dynamic website usually all business processes of a business organization are linked with the website of the organization. This is resulted in designing of a complex and gigantic website which may result in slow download and unfriendly navigation. Satisfying the end user need is one of the key principles of designing an effective website. As there are different users for give...

The proposed type of hierarchical fuzzy systems is based on the rule base hierarchy. A quite new algorithm for designing a hierarchical fuzzy system from a conventional fuzzy system is developed and implemented. The important part is the unification procedure. Redundant intermediate labels are found and subsequently unified. Basic requirements are fulfilled – subsystems of a hierarchical system...

In the real word, the decision-making problems are very vague and uncertain in a number of ways. Most of the criteria have interdependent and interactive features, so they cannot be evaluated by conventional measure method. Such as the feasibility, thus, to approximate the human subjective evaluation process, it would be more suitable to apply a fuzzy method in the environment-watershed plan to...

Sistan region is one of the most important agricultural areas in the province of Sistan and Baluchistan. Therefore, given the heterogeneity in agriculture and recognizing these differences, the aim of this study was to obtain the level of development of agriculture in the Sistan region. To obtain this purpose two Fuzzy Analytical Hierarchy Process (FAHP) and the numerical taxonomy was used in a...
