Identification,
Analysis and Solution of
the Information Gaps in the Production Planning and Control
Function in a Manufacturing Set-up
-- Arnab
Saha
In
this paper, the author presents a methodology to analyze the
information gaps in any of the business functions of an organization,
and arrives at a methodology to bridge those gaps. The key
point here is to firstly arrive at the information gaps and
then understand the root causes for these gaps. Then the root
causes are solved, thereby bridging those information gaps.
The author also presents how IT is an effective and practical
tool to solve these information gaps.

On
the Strategy of Supply Hubs for CostReduction and Responsiveness
-- Earl
Barnes, Jim Dai, Shijie Deng,
Doug Down,Mark
Goh,
Lau Hoong Chuin, Moosa Sharafali
A
supply hub is a location close to a manufacturing facility
where all or some of its supplies are warehoused with the
agreement that the materials will be paid for only when consumed.
Supply hub is an innovative strategy employed by especially
the electronics industry to achieve cost reduction. After
tracing the developments leading to the establishment of supply
hubs, the paper describes the dynamics of the operation of
supply hubs. Case examples are provided to highlight the current
practices and finally, some research issues are identified.

Optimization
of Warehousing with Correlation Analysis
-- Ramani
VV, Dheeraj Akula
This
research paper concentrates on the optimality of warehousing
in various industries, in particular the fertilizer industry.
Many industries, mainly the fertilizer industry, experience
irregular demand during the year. This makes warehousing a
critical function for the distribution department. A model
of analysis warehousing has been suggested here. This model
has been tested by application on the warehousing operations
of a fertilizer company.

Evaluating
Technical Efficiency of Visakhapatnam Port: A Data Envelopment
Analysis
-- Mukesh
Kumar , Vijayalakshmi
In
a world where structures are changing rapidly, it is vital
for an organization to monitor their performance continuously.
The quest for greater efficiency is never ending as managers
are always under pressure to improve the performance of their
organizations. In this paper, the technique of Data Envelopment
Analysis is used to study the efficiency trend of Visakhapatnam
Port during the period 1977-78 to 1999-00. The results reveal
that the port was experiencing very low level of technical
efficiency till 1990-91 due to underutilization of labor as
well as different cargo handling equipment. However, the efficiency
has improved significantly since 1990-91 onwards and this
port turned to be fully efficient since 1995-96 through 1999-00.
This improvement in efficiency was found after liberalization
mainly as a result of increase in the trade activities as
well as mechanization of port.

Measurement
of Technical Efficiency: Issues and Applications
This
paper tries to measure Technical Efficiency (TE) in one of
the India's largest complex of spinning units (consisting
of four plants) using Data Envelopment Analysis (DEA). This
is a non-parametric technique of estimation, optimizing on
each individual observation and in the process constructing
a discrete piece-wise frontier determined by the set of Pareto
efficient units. By using this technique for measuring technical
efficiency, many limitations of the conventional method of
estimation can be avoided. And it also provides information
about the efficient use of different inputs in the production
process. By using DEA in this study, it was possible to identify
the reasons for relative technical efficiency across the four
plants and in the process, the input slacks were also recognized.

Research
and Development of a Hybrid Rapid Manufacturing Process
-- F W Liou,J Choi, RG Landers, V Janardhan,
SN Balakrishnan
and S Agrawal
This paper presents the research and development of a hybrid
rapid manufacturing process being developed at the University
of Missouri-Rolla. This process include a laser deposition
and a 5-axis CNC milling system. By combining laser deposition
and machining processes, the resulting hybrid process can
provide greater build capability and better accuracy and surface
finish. The hybrid process can build some features that are
difficult to build in using a purely deposition process. The
issues and related approaches in the research and development
of the hybrid deposition-machining process, including laser
deposition process, system design and integration, process
planning, and sensor selection and control, are discussed.

Summary
Integrating
Closed-loop Supply Chains and Spare Parts Management at IBM
-- Debanjan
Bhattacharya
As
more companies recognized the benefits of closed-loop supply
chains that integrate product returns into business operations,
IBM had been among the pioneers seeking to unlock the value
dormant in these resources. The research paper developed an
analytic inventory control model and a simulation model to
address the issues like choice of recovery opportunities to
use, the channel design, and the coordination of alternative
supply sources in a project exploiting product returns as
a source of spare parts.

Summary
Critical
Chain
-- Debanjan
Bhattacharya
Critical
Chain, the book written by Eliyahu M Goldratt is one of the
books on project management. In the book he applies the theory
of constraints, and the scheduling in a project. In this book,
he describes the effects of the constraints and the scheduling
on any project. Critical Chain addresses several key problems
in project scheduling. Critical Chain project management uses,
primarily, deterministic calculations. The book has been written
in a very lucid form where each and every step associated
with the project and its repercussion is explained.
