 This paper presents an inventory model with non-instantaneous receipt under the condition of permissible delay in payments. Certain items like volatiles deteriorate during production process. In this paper, we consider deterioration into two phases i.e. phase 1 and phase 2. The purpose of this paper is to determine the optimal replenishment policies under conditions of non-instantaneous recei...

Several procedures have been employed to examine the impacts of subsidies on different indices in an economy. This paper proposes a new approach enabling one to compare direct and indirect payments on households. To this end, the impact of government payments is examined on Gross Regional Products, Employment, Income Distribution and Inflation of Golestan Province in Iran through a Social Accou...

In this paper, Economic Order Quantity ( ) based model for non-instantaneous deteriorating items with imperfect quality, permissible delay in payments and inflation is proposed. We adopt a time-dependent demand function. Also, the effects of time value of money are studied using the Discounted Cash Flow approach. Moreover, we assume that orders may contain a random proportion of defective items...

Background: Informal payments can cause delayed access to health care services, forcing people to sell their properties for cost of treatment; and as a result, they lose trust in the health system. Considering the importance of this issue, this study was conducted in 2016 to identify solutions to reduce and eliminate informal payments in Iran’s health system.    Methods: Initia...

Therfore, this study was conducted to systematically review and meta-analyze the status of these payments in Iran's health care system.    Methods: Required data were collected through searching the following key terms: "Unofficial", "Informal ...

This paper is concerned with the issue of side payments between content providers (CPs) and Internet service (access bandwidth) providers (ISPs) in an Internet that is potentially not neutral. We herein generalize past results modeling the ISP and CP interaction as a noncooperative game in two directions. We consider different demand response models (price sensitivities) for different provider ...

We analyze the allocation of priority in queues via simple bidding mechanisms. In our model, the stochastically arriving customers are privately informed about their own processing time. They make bids upon arrival at a queue whose length is unobservable. We consider two bidding schemes that differ in the definition of bids (these may reflect either total payments or payments per unit of time) ...
