Heuristic approaches to determine base-stock levels in a serial supply chain with a single objective and with multiple objectives [An article from: European Journal of Operational Research] Overviews

Description:
This paper deals with the problem of determination of installation base-stock levels in a serial supply chain. The problem is treated first as a single-objective inventory-cost optimization problem, and subsequently as a multi-objective optimization problem by considering two cost components, namely, holding costs and shortage costs. Variants of genetic algorithms are proposed to determine the best base-stock levels in the single-objective case. All variants, especially random-key gene-wise genetic algorithm (RKGGA), show an excellent performance, in terms of convergence to the best base-stock levels across a variety of supply chain settings, with minimum computational effort. Heuristics to obtain base-stock levels are proposed, and heuristic solutions are introduced in the initial population of the RKGGA to expedite the convergence of the genetic search process. To deal with the multi-objective supply-chain inventory optimization problem, a simple multi-objective genetic algorithm is proposed to obtain a set of non-dominated solutions.

Great Price "iPhone Objective-C 2.0 Programming Exercises 2nd Edition" Today

Price : $4.95

iPhone Objective-C 2.0 Programming Exercises 2nd Edition Overviews

This 2nd Edition of these popular iPhone Objective-C 2.0 exercises are for you if you are either a newbie or an expert iPhone Objective-C 2.0 software developer, and you need to learn, practice, and improve your iPhone Objective-C 2.0 software development skills.

The approach taken here is unique. Every exercise focuses on a key and important skill. Using a clear, step-by-step writing style, each exercise shows the exact code you need to enter. The exercises were written for use with Xcode, the Objective-C 2.0 development tool included with the iPhone OS SDK.

Unlike books that focus on Mac OS X Objective-C 2.0, the exercises in this book were written from scratch to focus on iPhone Objective-C 2.0 programming.

NOTE: The 1st Edition of these exercises did everything from the command-line. This 2nd Edition now does everything using the Xcode development tool that is included with the iPhone OS SDK.

The only prerequisite for these exercises is an eagerness to learn. While it helps to have a background in object-oriented programming, that is not a requirement. The exercises explain new concepts when they are needed, in a step-by-step, easy-to-understand, manner.

If you are an existing C/C++, C#, Flash, Java, PHP, Python, Ruby or similar developer, then you'll enjoy how Objective-C 2.0 handles object-oriented programming. Objective-C was influenced by SmallTalk, one of the early object-oriented programming languages. In turn, Objective-C influenced the Java language designers, which in turn influenced the C# language designers.

iPhone OS uses Objective-C 2.0 as it's programming language, which is a superset of the C programming language. As you work through these exercises, the Objective-C 2.0 concepts will be covered as you come to them. It's OK if you do not have experience with Objective-C 2.0; just start Exercise 1 and work your way forward.

If you have access to a Mac OS X system, along with the iPhone OS SDK (Software Developers Kit), then you can read each exercise, and perform each step, using the iPhone OS SDK.

However, even if you do not have a Mac OS X system with the iPhone OS SDK, you can still read and follow along "in your mind". When you do have access to a Mac, you'll know exactly what to do.

Corporate optimal production planning with varying environmental costs: A grey compromise programming approach [An article from: European Journal of Operational Research] Overviews

This digital document is a journal article from European Journal of Operational Research, published by Elsevier in 2004. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
Corporate environmental and resources management has become more strategically oriented when many pollution charges, environmental taxes, and resources conservation fees have been gradually imposing to the industry. The need for explicit consideration and incorporation of varying environmental costs within production-planning program is becoming critical to corporate management. This paper attempts to assess an optimal production-planning program in response to varying environmental costs in an uncertain environment. The optimal production strategy concerning numerous screening of possible production alternatives of dyeing cloth in a textile-dyeing firm in terms of market demand, resources availability, and impact of environmental costs is treated as an integral part of the multi-criteria decision-making framework based on the grey compromise programming approach. It covers not only the regular part of production costs and the direct income from product sales but also the emission/effluent charges and water resource fees reflecting part of the goals for internalization of external cost in a sustainable society. In particular, all the crucial variables in the model are addressed by interval expressions, the same as they are frequently applied in the grey systems theory, in support of a vital uncertainty assessment, which is much better suited for this particular study than other approaches. Research results demonstrate the applicability and significance of such an approach based on a case study. Industry looking for the competitive advantage of environmental management must be aware of the potential benefits from such an integrated production-planning program once the trend of increasing pollution charges, environmental taxes, and resources conservation fees remains.

Great Price "The Cassini-Huygens Mission: Overview, Objectives and Huygens Instrumentarium" for $125.56 Today

Price : $252.00

The Cassini-Huygens Mission: Overview, Objectives and Huygens Instrumentarium Overviews

The joint NASA-ESA Cassini-Huygens mission to Saturn is the most ambitious planetary mission since the VEGA mission to Venus and Halley in 1985/86 and the Viking arbiters and landers to Mars in 1976. Perhaps Cassini is even more ambitious than these earlier missions, or at least more daring, as it is being attempted as a single launch unlike early missions such as VEGA, Viking and Voyager that benefited from the security of a redundant spacecraft. This volume describes the mission, the orbiter spacecraft, the Titan atmospheric probe and the mission design in articles written by its project scientists and engineering team. These are followed by five articles from each of the discipline working groups discussing the existing knowledge of the Saturnian system and their goals for the mission. Finally, each of the Huygens entry probe instrument teams describes their instruments and measurement objectives. These instruments include an atmospheric structure instrument, an aerosol pyrolyser, an imager/radiometer, a gas chromatograph, a surface science package and a radio science investigation. This book is of interest to all potential users of the Cassini-Huygens data, to those who wish to learn about the planned scientific return from the Cassini Huygens mission and those curious about the processes occurring on this most fascinating planet. A second volume is in preparation that describes the instrumentation carried by the orbiter.

Great Price "Beginning Mac OS X Snow Leopard Programming" for $21.87 Today

If you are an experienced programmer desiring to master developing software on Mac OS X, then this book is the one to start with. The book is particularly well written and covers all the basics of both Mac OS X application and script programming. I can't think of a better way to get starting with Mac OS X than this book for a broad understanding of programming on the Mac.

The book is particularly well written and very easy to follow (that is if you are an experienced programmer). Better "how to" dev writing than I have see in a long time. Michael and Drew are to be commended. And I am very picky about technical book readability.

These guys make the quirky Objective-C easy to understand and master.

There are more in-depth Mac OS X dev books, but, by all means, start here first.

Beginning Mac OS X Snow Leopard Programming Features

Useful Book But Too Much Fluff at the Start - Maros -
All in all, this is a OK book for a beginner. The (major) problem is this is one of those books that throws the theory of the OS, frameworks, components, etc at the beginning.

This takes up a good amount of pages without letting the user get their hands dirty. Not only that, more fluff is taken up with images of how to work Xcode, Interface Builder, and other tools. Still, without the user really getting their hands dirty.

In the end, You'll be trudging through a total of just over 144 pages before you get to Chapter 6: C Programming. Now to be fair, once you get there the book starts to shine. After a quick delve into 'C', Chapter 7: Objective C begins on page 229. Then Cocoa & Doc-Based & Core-Data (pg 291).

A (short) Overview of Scripting Languages begins on page 389, which leads into BASH (pg 425). Lastly, AppleScript (pg 487) & (Dashboard) JavaScript are Discussed (pg 553). The Appendix (etc) begins on pg 591.

I think the best audience for this book are the ones with some programming experience who won't freak out over a different GUI API/OS. (Like myself.) These are the people that will immediately go to the sections they need and make the most of it. (And then read the fluff if desired.) Because it's divided into multiple programming languages the handling is somewhat (understandably, IMO) cursory, but fairly passable.

It's more at a 3.5 rating if taken in this context. However, dropped to flat 3 because of the overload of fluff at the beginning.

iPhone SDK Programming, A Beginner's Guide

Great Price "iPhone SDK Programming, A Beginner's Guide" for $19.01 Today

I would like to say that this book is great. It's definitely a great book for beginners.
The book teaches how to do the basic stuff such as navigation controllers, table views and simple stuff such as buttons, images, view controllers, etc.
However, I noticed this book seemed to be rushed...for example, the author teaches how to make the navigation bar disappear
using the viewWillAppear method but then doesn't tell you how to get it back and where to place code (PAGE 178).
I found out that you must incorporate setNavigatioBarHidden:NO animated:YES to view didLoad method in the second view controller just to get the Navigation Bar back.
It was frustrating to search through the net and then figure it out on your own.

I recommend this book for absolute beginners, who would like to tinker but not for production.
Although the author has written a decent book, I hope that the author realizes that improvements are needed such as:

1) Completing methods when they are introduced.
2) Help the reader understand why they are doing some things introduced.
3) Check the book for logical reasoning in the reader's perspective, such as the aformentioned navigationbar.
4) If a publishing company rushes the author to print an unfinished book, then the author needs to find a new publisher.

Fun Intro to iPhone Programming. - David House - San Francisco, CA
Easy to understand introduction to iPhone programming. Along with coding, Interface Builder is utilized in the examples and exercises to give the reader a better sense of how it can be used in development. Overall I've learned a lot from this book.

No Easy Access to Table of Contents in Kindle for iPhone Version - Web Phillips -
I am giving the Kindle for iPhone version of this book a low review, because it lacks an easy access to the Table of Contents.

You cannot easily navigate to the Table of Contents of this book using the "Go to" feature in the Kindle for iPhone app, because it states that no Table of Contents is available for this book.

However, a Table of Contents for the Kindle for iPhone version of this book does exist, but you have to manually flip through the pages on your iPhone or iPod Touch to find it.
