Novel Approaches For Demand Forecasting In Semiconductor Manufacturing - Kumar, Chittari Prasanna
Accurate demand forecasting is a key capability for a manufacturing organization, more so, a semiconductor manufacturer. Many crucial decisions are based on demand forecasts. The semiconductor industry is characterized by very short product lifecycles (10 to 24 months) and extremely uncertain demand. The pace at which both the manufacturing technology and the product design changes, induce change in manufacturing throughput and potential demand. Well known methods like exponential smoothing, moving average, weighted moving average, ARMA, ARIMA, econometric methods and neural networks have been used in industry with varying degrees of success. We propose a novel forecasting technique which is based...

Deterministic Scheduling Of Parallel Discrete And Batch Processors - Venkataramana, M
Scheduling concerns the allocation of limited resources to tasks over time. In manufacturing systems, scheduling is nothing but assigning the jobs to the available processors over a period of time. Our research focuses on scheduling in systems of parallel processors which is challenging both from the theoretical and practical perspectives. The system of parallel processors is a common occurrence in different types of modern manufacturing systems such as job shop, batch shop and mass production.
A variety of important and challenging problems with realistic settings in a system of parallel processors are considered. We consider two types of processors comprising...

Impact Of Option Introduction On Different Characteristics Of Underlying Stocks In NSE, India - Joshi, Manisha
Financial Derivatives are one of the most popular and emerging innovations in the field of financial engineering. Since their inception, there has been a phenomenal growth in the volumes of derivatives traded all over the world. Financial markets are known to be extremely volatile and derivatives provide a way of eliminating or reducing the risks involved in these markets. Since these instruments derive their value from some underlying asset, trading in these instruments is bound to affect the underlying assets. Thus it becomes important to examine what these effects are and whether they have been favourable or detrimental to the...

Dynamic Control Mechanism For Customer Buy Down Behavior - Girirengan, S
Revenue Management (RM) has become one of the most successful application areas of
Operation Research. What started off as an obscure practice among few airlines in U.S
in early seventies, has attained the status of mainstream business practice, thanks to
the major success enjoyed by companies applying RM. Over the same period, academic
and industrial research on the methodology of RM has also grown rapidly. Despite the
vast technical literature on the subject of revenue management, relatively few papers
explicitly model the customer’s choice behavior. Such a behavior of customers could
have major impact on revenue realized by an organization. Motivated by this, we focus
on addressing the...

Cellular Services Market In India : Predictive Models And Assessing Interventions - Shrinivas, V Prasanna
The Objective of this thesis is to address some interesting problems in the Indian cellular services market. The first problem we address relates to identifying important change points that marked the evolution of the telecom market since Indian Independence. We use the data on per-capita availability of telephones in India to this effect. We identify important change points that mapped to the computerization move in 1989, the liberalization and globalization policies starting from 1991 and subsequently the introduction of NTP 1997 and NTP 1999. We also identify the important change points that mark the growth of cellular services subscriber base...

Performance Evaluation Of Skill-Based Routing In An Inbound Call Center Using Stochastic Petri Nets - Mazumdar, Chandra Sen
Call centers have become a preferred and prevalent means for companies to communicate
with their customers. As a consequence of this, the call center industry has seen a huge growth in both volume and scope in the last couple of decades. Operations managers
are challenged with the fact that personnel costs, especially staffing, account for over
65% of the cost of running the typical call center. The trade-off between service quality
(marketing) and efficiency (operations), thus naturally arises, and a central goal of ours is to contribute to its understanding.
We present here a server switching policy for routing of calls to Customer Service
Representatives (CSR)...

Collaborative Boundary Crossing Behaviours Of Product Development Teams : Role Of Direct And Indirect Factors - Randhir, R P
Emerging markets are fraught with uncertainty, diverse global players, rapid technological change, wide-spread price wars, and seemingly endless reorganization (Ilinitch, 1996). These changes have presented challenges to organizations in the form of shorter product cycles, increased segment fragmentation, blurring industry boundaries, breaking corporate hierarchies, and increased interdependence of world markets (Ozsomer et. al., 1991). Organizations are responding to competition by capitalizing on global policies and adopting self-directed teams and horizontal structures that enhance external activities. To do this organizations are getting conscious of the boundaries they are operating in. With hyper competition and globalization organizations blur boundaries to gain maximum...

Heuristic Methods For Job Scheduling In A Heat Treatment Shop To Maximize Kiln Utilization - Srinidhi, S
Scheduling in the context of manufacturing systems has become increasingly impor-
tant in order for organizations to achieve success in dynamic and competitive scenarios.
Scheduling can be described as allocation of available jobs over resources to meet the
performance criteria defined in a domain.
Our research work fo cuses on scheduling a given set of three-dimensional cylindrical
items, each characterized by width wj , height hj, and depth dj , onto parallel non-identical rectangular heat treatment kilns, such that the capacities of the kilns is optimally used. The problem is strongly NP-hard as it generalizes the (one-dimensional) Bin Packing Problem (1BP), in which a...
