The present study was focused on supply chain analysis of fresh guava in order to evaluate existing marketing supply chains (SC1: Producer - Consumer, SC2: Producer - Retailer - Consumer, SC3: Producer - Commission agent - Retailer - Consumer, SC4: Producer - Commission agent - Wholesaler - Retailer - Consumer) for two variety (allahabad safeda and apple guava) of guava. The gross marketing pri...

Objective: Market anomalieschange with economic conditions, stock markets, selected samples, time periods and differences between industries. Revision of past forecasts leads to forecast error. The revisions result from new information. On the other hand, some managers slowly revise their forecasts in responding to new information. Therefore, the purpose of this research is to investigate the r...

Today's large scale networks such as the Internet emerge from the interconnection of privately owned networks and serve heterogeneous users with different service needs. The service providers of these networks are interested in maximizing their profit. Since the existing pricing scheme cannot satisfy their needs, the service providers are looking for new pricing mechanisms. However, designing a...

the effects of cutting subsidy on broiler production in kerman province were investigated after privitization. in this regard a random sample of 32 poultry farms in kerman were chosen and the farmers were interviewed. the unit- output - price profit function model was used to determine the supply and demand elasticity of broider products. the results show that the profit of poultry farms increa...

We study a risk-averse newsvendor problem with quantity competition and price competition. Under the Conditional Value-at-Risk (CVaR) criterion, we characterize the optimal quantity and pricing decisions under both quantity and price competition. For quantity competition, we consider two demand splitting rules, namely proportional demand allocation and demand reallocation. Although competition ...

We study an inventory system that supplies price-sensitive demand modeled by Brownian motion. The optimal pricing and inventory replenishment decisions under both long-run average and discounted objectives are derived, and related to or contrasted with previously known results. In addition, we emphasize the interplay between pricing and replenishment decisions, and the ways in which they react ...

In this paper we use the Generalised Population Based Incremental Learning (GPBIL) in order to find profit-maximizing strategies for the Artificial Payment Card Market (APCM). The artificial market has modeled explicitly a multidimensional consumers’ and merchants’ demand for payment instruments. Given the complex shape of the demand, we have found that the GPBIL effectively explores the areas ...

This study explores the problem of optimally dynamic joint decisions: replenishment quantity, retail price and depletion time, in a vertically decentralized single-retailer and single-supplier supply chain over a dynamic multi-period planning horizon, subject to multivariate demand function and deteriorating goods with shortages allowed and with no consideration of fixed costs. This research us...
