When technology uses in education and other activities, there may be some communication barriers. And also, quality process has an important role in higher education institutes. If a higher education institute tries to pursue a quality management system, ...

by developing the level of life in societies, the need for new resources of energy becomes more important. in almost all cases, the aim is to convert one form of energy to the electrical form. with advances of technology and use of new electric and electronic devices and gadgets, the need for electrical energy is increasing and providing stable and continuous electric power becomes very importa...

Staffing and Control of Many-Server Service Systems Itai Gurvich This dissertation considers large-scale service systems with multiple customer classes and agent types. Customers are classified according to their processing requirements, service-level guarantees, or both. The customers are served by agents of different types. These are classified according to the subset of customer classes that...

In the variable supply auction considered here, the seller decides how many costumers with unit demand to serve after observing their bids. Bidders are uncertain about the seller’s cost. We experimentally investigate whether a uniform or a discriminatory price auction is better for the seller in this setting. Exactly as predicted by theory, it turns out that the uniform price auction produces s...

In modern society, many companies have large data records over their individual customers, containing information about attributes, such as name, gender, marital status, address, etc. These attributes can be used to link costumers together, depending on whether they share some sort of relationship with each other or not. In this thesis the goal is to investigate and compare methods to predict r...

in designing a product designers should take in to consideration several factors such as customers’ needs and opinion as well as the designing features and the relationship between these two.since each designer has his own idea, it is worth for both designer and producers to find a way for combining the customer needs and the designing of the product increases with the rate of customer satisfac...

We describe the development and implementation of a Java-based, multi player, multi-group, distributed simulation and game. The Supply Chain game described here is based on the famous "Beer Distribution Game" (Sterman, 1989). Group, synchronous, distributed Java-based applications are both feasible and useful for gaming and management simulation processes in both learning and research capacitie...

As the world population increases, the sustainable usage of natural resources becomes an issue that humanity and technology are urgently asked to face. Energy represents a relevant example from this perspective and the strong demand coming from developed and developing countries shoved the scientists worldwide to intensify their studies on renewable energy resources. At the same time, due to th...

Economical harvesting of electrical energy on a large scale considering the environmental issues is a challenge. As a solution, Microgrids (MGs) promise to facilitate the widely penetration of renewable energy sources (RESs) and energy storage devices into the power systems, reduce system losses and greenhouse gas emissions, and increase the reliability of the electricity supply to the customer...
