A new genetic algorithm for the tool indexing problem

Diptesh Ghosh

The tool indexing problem is one of allocating tools to slots in a tool magazine so as to minimize the tool change time in automated machining. This problem has been widely studied in the literature. A genetic algorithm has been suggested in the literature to solve this problem, but its implementation is non-standard. In this paper we describe a permutation based genetic algorithm for the tool indexing problem and compare its performance with an existing genetic algorithm.

Intention to Participate in Cause Related Marketing:
Influence of Cause

Sonal Kureshi and Sujo Thomas

The most widely accepted definition for CRM is provided by Varadarajan and Menon (1988) and it defines CRM as "a process of formulating and implementing marketing activities that are characterized by an offer from the firm to contribute a specified amount to a designated cause when customers engage in revenue-providing exchanges that satisfy organizational and individual objectives". Several organizations in India like Dabur, Marico, P&G and ITC have implemented this form of social marketing practice.
In the view of the growing significance of CRM in countries like India which have been facing numerous social challenges, it becomes crucial to understand what factors lead to effective implementation of CRM. This study will provide insights into both type and scope of cause and their bearing upon consumer CRM participation intention.
Consumer data was collected using a structured questionnaire from the western region of India. Reponses pertaining to two aspects about the cause of the initiative, 'type of cause' and 'scope of cause' were collected. Results showed that consumer's interest in participation were found to differ significantly across both type of cause and scope of cause.

Intuitionistic Fuzzy Model of Discrete Choice

Manish Aggarwal

The discrete choice models yield a decision-maker (DM)'s choices on the basis of the criteria values. In practice, however, the choices depend on the degree of enjoyment that an evaluating agent derives from a criterion, and which varies from individual to individual. To this end, we introduce an intuitionistic fuzzy variant of multinomial logit model of discrete choice that is able to explicitly consider the imprecision in the utility value, a DM associates with a criterion.

Simulation of Expected Value Method in Project Risk Management in Two Different Construction Projects

Goutam Dutta

In this paper, we discuss the application of the expected value method of risk management. In the expected value method, there are two possible state of activity - as planned and risky. In a risky state, an activity will require additional time or cost, known as corrective cost and time, over and above the basic cost estimate or basic time estimates. We simulate two different construction projects - a metro construction project and a rural tourism project. The time and cost of an activity have been assumed to follow four different distributions - beta, uniform, normal and triangular. The simulation is performed on the basis of EVM and the expected cost and expected times are computed. We compare and contrast the project completion time and project cost of these four distributions.

FRIW: Free Radicle Inspired Walk
Capturing Social Bonds for a Realistic Human Mobility Model

Kavitha Ranganathan

Studies on mobile applications for ad-hoc networks predominantly rely on simulations to evaluate various distributed algorithms. This has given rise to the need for realistic mobility models that incorporate social characteristics of human mobility. Based on basic properties of user movements captured via GPS traces and user interviews, we propose FRIW (Free Radicle Inspired Walk). FRIW leverages the free radicle concept from chemistry and social network theory to model social ties and group mobility in a campus setting. We find that FRIW is successful in generating realistic mobility patterns that can be used for modelling user movements in ad hoc network simulations.

Nonlinear 0-1 knapsack problem with capacity selection

Sachin Jayaswal

We study a nonlinear 0-1 knapsack problem with capacity selection decision, as it arises as a part of facility location/service system design problems with congestion. The capacity selection decision gives rise to a non-convex objective function. We present two cutting plane based solution approaches: one based on Generalized Benders decomposition based, and the other based on a reformulation of the problem using additional auxiliary variables, followed by outer linearization of a resulting simple concave func-
tion in the constraint.

Classification Shifting: Impact of Firm Life Cycle

Neerav Nagar and Kaustav Sen

Purpose - This paper examines whether firms in the decline stage of life cycle manipulate core or operating income through misclassification of operating expenses as income-decreasing special items.
Design/methodology/approach - Our sample comprises of firms from an emerging market, India with data from 1996-2011. We use the methodology given in McVay (2006) and multiple regressions.
Findings - Managers of Indian firms also engage in classification shifting, primary incentive being desire to avoid reporting of operating losses. Further, the use of classification shifting is dependent upon the stage of life cycle in which firm is in. Specifically, firms in the decline stage of life cycle are more likely to use classification shifting to avoid reporting of operating losses.
Practical implications - The paper sheds light on a critical phase of the firm life cycle-decline, which increases the possibility of use of classification shifting-an earnings management technique which auditors, investors and regulators find tough to detect.
Originality/value - We extend the literature on classification shifting, and present first evidence that such shifting is more likely to take place during the decline phase of firm life cycle.

A Game Theoretic Approach to Community based Data Sharing in Mobile Ad hoc networks

Premm Raj H. and Kavitha Ranganathan

Government interventions on usage of free speech
for communication has been rising of late. The government of Iraq's ban on the Internet, ban of mobile communications in Hong Kong student protests highlight the same. Applications
like Firechat which use mobile ad hoc networks (MANETs) to enable off the grid communication between mobile users, have gained popularity in these regions. However, there have been limited studies on selfish user behavior in community
data sharing networks. We wish to study these data sharing communities using game theoretic principles and propose a normal form game. We model selfishness in community data sharing MANETs and define the rationality for selfishness
in these networks. We also look at the impact of altruism in community data sharing MANETs and address the issue of minimum number of altruistic users needed to sustain the MANET. We validate the novel model using exhaustive
simulations and empirically derive important observations.

Soft Information Set and its Application in Multi Criteria Decision Making

Manish Aggarwal

An information source value is perceived
differently by different agents. In this paper, we present a new knowledge representation structure, termed as soft information set (SIS), to provide a parameterized representation of the information values, as perceived by an agent. The properties of SIS are investigated and the
notion of relations in SIS is devised. SIS has potential to facilitate multi-criteria decision making (MCDM) under uncertainty, involving different information source values and agents. Its usefulness as a uncertainty representation
tool in MCDM is illustrated through case-studies.

Information Utility based Decision Support Framework

Manish Aggarwal

We introduce a novel entropy framework
for the computation of utility on the basis of an agent's subjective evaluation of the granularized information source values. A concept of evaluating agent as an information gain function of this entropy framework is proposed, which takes as its arguments both an information source value and the agent's evaluation of the same. A method to determine the agent's perceived utility values is also developed. Based on these values, several
new utility measures are designed for the valuation of the information source values, perceived utilities, and the evaluating agent.
