One of the major problems in Data Envelopment Analysis (DEA) is to determine the projection of inefficient Decision Making Units (DMUs) into the efficient frontier. In conventional DEA models, inputs and outputs of inefficient DMUs alter arbitrarily for reaching to the efficient frontier. Nevertheless, sometimes the ability of DMUs is defined and restricted. Moreover, there are situations in th...

decision support systems (dsss) are prevalent information systems for decision making in many competitive business environments. in a dss, decision making process is intimately related to some factors which determine the quality of information systems and their related products. traditional approaches to data analysis usually cannot be implemented in sophisticated companies, where managers need...

The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...

Second, it represents the fundamental architecture of an enterprise’s data, and as such is an ideal starting place for database design. To be sure, the final structure of a database may differ from the data model for good and valid reasons, but the closer it remains to the original structure, the more likely it is to be able to resist requirements for future changes. To the system designer and ...

This paper surveys the dominant models in the literature of positive Ethical Decision-Making Models (hereafter, EDMMs): an area in the academic sub-discipline of business ethics. While this group of eight models is not exhaustive, it is, I believe, definitive. The survey does not address other decision-making apparati, e.g., game theory. Neither does it address normative Ethical Decision-Making...
