in this research two models for pricing and inventory decisions of complementary products with and without deterioration assumption are developed. in both of them, we assumed that the demand function of each product is dependent on own price and the price of another one. the aim of this paper is to optimize the total profit of integrated system such that the optimal values for the price of each...

wheat production with the least use of chemical inputs is an important goal of modern farming to decrease of negative effects of the use of chemical inputs. this paper has estimated the virtual profit of organic wheat in transition period using a cross sectional data of 453 wheat producers of khorasan razavi province during 2007. a model introduced to this objective so that it has ability of es...

warranty as a kind of service contract today plays a role key in business and legal transactions. in this paper, we present a manufacturer, an agent and a customer's model under different service contracts suggestions. the manufacturer's profit is maximized by determining sale price, warranty period and warranty price. in addition we obtain optimal maintenance cost or repair cost for ...

We introduce a wholesale pricing strategy for an incumbent supplier facing with a competitive counterpart. We propose a profit function which considers both the present loss and future loss from a wholesale price and then study the optimal wholesale prices for different objectives about this profit function for the incumbent supplier. First, we achieve an optimal wholesale price for the incumbe...

producers and consumers’ price behavior were analyzed in chicken meat market in fars province. monthly average producers and consumers prices from june 1997 to july 2008 were taken into account. changes in the producer and consumer prices indicated that the prices follow an increasing trend with much fluctuations. marketing margin has an increasing trend of violent fluctuations. the result of g...

In some situations the producers desire to maximize total profit of Decision Making Units (DMUs) while the inputs and outputs prices of DMUs change from one time period to another. In this paper, the researchers develop productivity index when producers are going to maximize total profit when the price of inputs and outputs are known.The proposed method uses all price information about inputs a...

This article considers the deterministic singular optimal control problem of profit maximisation for inventory replenished at a variable rate and depleted by demand which is assumed to vary with price and stock availability. Optimal policies for the product order rate and price are derived using the maximum principle. Several initial inventory regions are identified as potential inventory state...

International data suggest that for-profit nursing homes tend to provide lower quality than not-for-profit nursing homes. In Germany, the relationships between profit orientation, price and quality of nursing homes have not been investigated. We performed an observational study using secondary data from statutory quality audits of all nursing homes in Germany. The relationships were analyzed bi...

Virtual power plant (VPP) can be studied to investigate how energy is purchased or sold in the presence of electricity market price uncertainty. The VPP uses different intermittent distributed sources such as wind turbine, flexible loads, and locational marginal prices (LMPs) in order to obtain profit. VPP should propose bidding/offering curves to buy/sell from/to day-ahead market. In this pape...
