Power allocation across users in two adjacent cells is studied for a wireless Code Division Multiple Access (CDMA) network with mixed voice and data services. We assume that each user has a utility function that measures the user’s satisfaction, or utility, as a function of the received Signal-to-Interference-plusNoise-Ratio (SINR). Each particular service (voice or data) is associated with a d...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

Taking into account competitive markets, manufacturers attend more customer’s personalization. Accordingly, build-to-order systems have been given more attention in recent years. In these systems, the customer is a very important asset for us and has been paid less attention in the previous studies. This paper introduces a new build-to-order problem in the supply chain. This study focuses on bo...

When evaluating of the senior manager’s performance is based on the achieving to budget and they have responsibility to report the capacity of resources which are in their part too; it is possible to create budget slack and effect on their performance evaluation by providing pessimistic and conservatively estimates or manipulated information of income and expenses. So, Senior Manager and Budget...

In this article, we present a cross-layer adaptive algorithm that dynamically maximizes the average utility function. A per stage utility function is defined for each link of a carrier sense multiple access-based wireless network as a weighted concave function of energy consumption, smoothed rate, and smoothed queue size. Hence, by selecting weights we can control the trade-off among them. Usin...

Multi-hop random access networks have received much attention due to their distributed nature which facilitates deploying many new applications over the sensor and computer networks. Recently, utility maximization framework is applied in order to optimize performance of such networks however delay is not limited and proposed algorithms result in very large transmission delays. In this paper, we...

We introduce a new interpretation of two re­ lated notions conditional utility and utility independence. Unlike the traditional inter­ pretation, the new interpretation render the notions the direct analogues of their prob­ abilistic counterparts. To capture these no­ tions formally, we appeal to the notion of util­ ity distribution, introduced in previous paper. We show that utility distributi...

Multi-hop random access networks have received much attention due to their distributed nature which facilitates deploying many new applications over the sensor and computer networks. Recently, utility maximization framework is applied in order to optimize performance of such networks, however proposed algorithms result in large transmission delays. In this paper, we will analyze delay in random...

This paper reexamines the role of money demand for the local dynamics of a sticky price model where money enters the utility function and monetary policy is either conducted according to a Taylor-type interest rate rule or to a Friedman-type constant money growth rule. It is shown that activeness, which is commonly recommended as a device for a stabilizing interest rate policy, leads to stable ...

OBJECTIVE To determine the cost effectiveness of total laparoscopic hysterectomy (TLH) versus total abdominal hysterectomy (TAH) in early stage endometrial cancer alongside a multicenter randomised controlled trial (RCT). METHODS An economic analysis was conducted in 279 patients (TLH n=185; TAH n=94) with early stage endometrial cancer from a societal perspective, including all relevant cost...
