PROCUREMENT PROCESS IN POWER ENERGY ENTERPRISE

The supply and procurement processes are extremely important for properfunctioning of power plants, especially for continuous production process because anybreaks have negative effects on the costs linked to idle time.supply management, procurement process

Nash Game Model for Optimizing Market Strategies, Configuration of Platform Products in a Vendor Managed Inventory (VMI) Supply Chain for a Product Family

This paper discusses how a manufacturer and its retailers interact with each other to optimize their product marketing strategies, platform product configuration and inventory policies in a VMI (Vendor Managed Inventory) supply chain. The manufacturer procures raw materials from multiple suppliers to produce a family of products sold to multiple retailers. Multiple types of products are substitutable each other to end customers. The manufacturer makes its decision on raw materials’ procurement, platform product configuration, product replenishment policies to retailers with VMI, price discount rate, and advertising investment to maximize its profit. Retailers in turn consider the optimal local advertising and retail price to maximize their profits. This problem is modeled as a dual simultaneous non-cooperative game (as a Nash game) model with two sub-games. One is between the retailers serving in competing retail markets and the other is between the manufacturer and the retailers. This paper combines analytical, iterative and GA (genetic algorithm) methods to develop a game solution algorithm to find the Nash equilibrium. A numerical example is conducted to test the proposed model and algorithm, and gain managerial implications.supply chain management;nash game model;vendor managed inventory

Risk-Smoothing Across Time and the Demand for Inventories: A Mean-Variance Approach

The standard production smoothing model of inventory demand cannot represent the added incentives for smoothing risks or explain the impact of market shocks that independently affect expectations and uncertainty. Those limitations are overcome by modeling inventory demand as a problem in deterministic optimal control, with the risk-averse firm maximizing utility that is a separable function of the mean and variance of returns and the firm controlling on two decision variables, production and inventory investment. Support for the mean-variance approach comes from regressions using Survey of Professional Forecasters data to show how changes in the mean forecasts of the GDP price deflator and changes in the disagreement among deflator forecasts can explain changes in aggregate inventory investment over time. Further support comes from the ability of the model to explain the excess volatility of industry output over sales—a fact at odds with the production smoothing theory.

Learning from Prices, Liquidity Spillovers, and Market Segmentation

We describe a new mechanism that explains the transmission of liquidity shocks from one security to another (“liquidity spillovers”). Dealers use prices of other securities as a source of information. As prices of less liquid securities convey less precise information, a drop in liquidity for one security raises the uncertainty for dealers in other securities, thereby affecting their liquidity. The direction of liquidity spillovers is positive if the fraction of dealers with price information on other securities is high enough. Otherwise liquidity spillovers can be negative. For some parameters, the value of price information increases with the number of dealers obtaining this information. In this case, related securities can appear segmented, even if the cost of price information is small.Liquidity spillovers, Liquidity Risk, Contagion, Value of price information, Transparency, Colocation

The Future of Retail Operations

Retailing consists of all the activities associated with the selling of goods to the final consumer. In this article, we review the research on retail operations published in Manufacturing & Service Operations Research (M&SOM) since 1999. We then discuss the current retail landscape and the new research directions it offers, in which M&SOM can play a prominent role

Classification of Empirical Work on Sales Promotion: A Synthesis for Managerial Decision Making

Sales Promotion activities have gained strategic focus as markets are getting complex and competitive. Key managerial concerns in this area are budget allocation across elements of promotions as well as trade vis. consumer promotion, how to design individual sales promotion techniques and a calendar in face of competitive promotions, how to manage them and evaluate the short-term and long-term impact of the same. The objective of this paper is to present, through Meta-analysis, an overview of recent contributions appearing in scholastic journals relevant to the field of Sales Promotion, to classify them into different classificatory framework, report key findings, highlight the managerial implications and raise issues. The database used is the EBSCO host available on VSLLAN (Library)- Indian Institute of Management Ahmedabad). The selection procedure consisted of peer-reviewed scholarly contributions for recent five year period. Out of more than 700 articles 64 article were selected which were analyzed for classifying them into • Perspective addressed: Manufacturer, retailer or consumer. • Market [country where the research was undertaken] • Type of promotion activity addressed - coupon, contest, price cut etc. • Management function addressed: planning, implementation, control [evaluation] • It was found that majority of the articles addressed manufacturers perspectives ; almost all studies were done in developed countries ; coupon as a consumer promotion tool was widely researched; and more than half of the articles were addressing planning related issues. Finally attempt has been made to synthesize managerial implications of the studies under broad topic areas for guidelines for managers.

Monetary Policy, Corporate Financial Composition and Real Activity

This paper addresses two fundamental questions about monetary policy, credit conditions and corporate activity. First, can we relate differences in the composition of debt between tight and loose periods of monetary policy to firm characteristics like size, age, indebtedness or risk? Second, do differences in companies’ financial compositions matter for real activity of firms such as inventory and employment growth? The paper offers some evidence from firms in the UK manufacturing sector which suggests the composition of debt differs considerably with characteristics such as size, age, debt and risk, it also shows a significant effect from financial composition and cash flow to inventory and employment growth.Monetary Policy, Inventory Investment, Employment, Firm Type
