A GA based optimal generation scheduling strategy is developed to solve the profit maximization problem for GENCO in the day ahead market. It is a multi objective formulation that includes the forecasted demand, forecasted market clearing price, startup cost and profit functions, besides the generating limits and demand constraints. The proposed GA approach is investigated on three unit and ten...

The relationship between the quality of finishing works, costs, market value, and profit, is presented and explained for residential buildings. The results show that the higher quality of finishing works increases profit for investors. As the maximum market price is limited, there is a limit when the investment in finishing work is no longer cost-effective as, after increase in costs, the marke...

It is assumed that in an n-firm single-product oligopoly without product differentiation the firms face an uncertain price function, which is considered random by the firms. At each time period each firm simultaneously maximizes its expected profit and minimizes the variance of the profit since it wants to receive as high as possible profit with the least possible uncertainty. It is assumed tha...

This paper evaluates the pricing and ordering policies of a retailer, facing a price-dependent stochastic demand, within a newsvendor framework, under different degrees of risk tolerance and under a variety of optimizing objectives. These are (i) maximizing expected profit, for a retailer who may be risk-seeker, riskaverse or risk neutral; (ii) deriving a maximin strategy of maximizing a minimu...

A fuzzy inventory model is proposed to maximize the profit in a two stage supply chain model. In this paper joint total profit of both buyer and vendor are calculated. Shortage for the buyer is allowed and it is completely backlogged. Number of shipments, selling price and order quantity are taken as decision variables. Graded mean integration representation method is applied for defuzzificatio...

Consider a retailer announces both the regular price and the post-season clearance price at the beginning of the selling season. Throughout the season, customers arrive in accord with a Poisson process. In this paper we analyze the impact of two types of customer purchasing behavior and two common in-store display formats on the retailer’s optimal expected profit and optimal order quantity. We ...

Search for structure in the financial markets has recently become an active field of research by scientists from different areas of expertise. The Efficient-Market Hypothesis states that the markets reflect all publically available information within their price. This also means that no profit higher than the average market returns allow can be gained using only the price information. However, ...

In reverse supply chain of e-waste, collectors (collecting e-waste from all kinds of resources) and processors (disassembling and disposing e-waste) play key roles and have connections based on interests. We present a Stackelberg leader(collector)follower(processor) dynamic game model with profit maximization purpose. When the supply and demand are relatively clear, major risk for the processor...

This paper deals with the coordination of pricing and order quantity decisions for two seasonal and substitutable goods in one firm. We assume that the customers are price sensitive and they are willing to buy the cheaper products, which is known as one way and customers-based price driven substitution. First, a mathematical model is developed for one firm, which contains two replaceable produc...

We compare welfare and profits under price and quantity competition in mixed duopolies, in which a state-owned public firm competes against a private firm. It has been shown that price competition yields larger profit for the private firm and greater welfare if the two firms move simultaneously, regardless of whether the private firm is domestic or foreign. We investigate Stackelberg competitio...
