Stochastic Modeling Is a Mathematical Term Paper

… The optimal policy from such a model is a single first-stage policy and a collection of recourse decisions (a decision rule) defining which second-stage action should be taken in response to each random outcome [5].

Solution approaches to stochastic programming models are driven by the type of probability distributions governing the random parameters. A common approach to handling uncertainty is to define a small number of scenarios to represent the future. In such cases, it is possible to compute a solution to the stochastic programming problem by solving a deterministic equivalent linear program. These problems are typically very large-scale problems, and so, much research effort in the stochastic programming community has been devoted to developing algorithms that exploit the problem structure, in particular in the….

Tactical and Strategic Planning

The work of Rushton, Oxley, and Croucher (2000) entitled: "The Handbook of Logistics and Distribution Management" states that the scheduling problems of vehicle routing are "relatively complicated." P.422. The reasons for this are stated to be that first of all "the different types of problems that can arise each "needs to be understood and approached in a different way" and secondly "the many detailed aspects that need to be taken into account and the various methods of algorithms that can be used to produce solutions." (Rushton, Oxley and Croucher, 2000) p.422 Problems may be of the nature of:

(1) Strategic;

(2) Tactical or operational;

(3) Interactive; and (4) Planning. (2000)

Evolution Over Time of Network Parameters Multiple Chapters

… Evolution Over Time of Network Parameters

In this chapter, we present the definitions and background material on the topics covered in this thesis along with the relevant literature survey. In network environment, traffic analysis must be carried out in ongoing bases in order to account for surfacing applications, there effort on traffic, and their possible control. Some analyses are extensive, but most entities opt for monitoring and alarms alerting them when malicious applications have entered the network. Form General Interne traffic analysis, studies have shown that even though, many emerging application take advantage of non-connected oriented transfer mechanisms like the one offered by the User Datagram Protocol (UDP); the TCP is the dominant transmission protocol in terms of byte load. Thus, many studies concentrate on…. [read more]


Spotlighting Samplings 4 Qualitative Research Research Paper

… Magilvy and Thomas (2009) explain that "qualitative research data are usually text data, narratives, and stories told by people about their experiences recorded digitally, on tape, on film, or in photographs, or in notes taken by the researcher" (¶ 4). After being analyzed, described and explained, the ensuring retrieved data may offer a detailed account of the experience "as lived."

As explained earlier in the study, research design illustrates the entire research process from the first notion of the research problem, to creating the data, analyzing and explaining the findings and ultimately publishing the results. In addition to the phenomenology method, the survey method, the ethnography method, and the case study method, the methods the current study examines, research designs also include, however, may not….

Supply Chain Planning Under Uncertainty a Real Options Approach Research Proposal

… Supply Chain Planning Under Uncertainty: a Real Options Approach

In a manufacturer's quest to manage its supply and demand chains, one simple word aptly portrays a certain, common, contemporary concern that a company can count on having to cope with - uncertainty.

In light of uncertainty and operational needs in the supply chain realm, this qualitative case study presents a survey of the supply chain planning, and real options literatures, while it also explores the intellectual developments in these areas as they relate to supply chain management. The initial segment of this study reviews supply chain planning and uncertainty, along with the challenges these components pose for the supply chain planner, and the planning process. The researcher also reviews a number of the most popular…. [read more]

Distribution Planning for Make to Order Manufacturers

The work of Chang and Makatsoris (nd) entitled: "Supply Chain Modeling Using Simulation" published in the International Journal of Simulation states that the key factor for success in business in today's global market is the management of the "entire supply chain." (Chang and Makatsoris, nd) it is held that it is acknowledged in today's "World-class organizations...that non-integrated manufacturing processes, non-integrated distribution processes and poor relationships with suppliers and customers" are not enough for the success of these organizations as they have come to "realize the impact of an organization's plan on the other areas of the supply chain." (Chang and Makatsoris, nd) the following illustration is that of the 'typical supply chain'…. [read more]


Using Fuzzy Logic for Scheduling Multiple Chapters

… 315). Even when executives make the effort to plan their projects carefully, they may overlook the most important ones in their attempt to organize all of the enterprise's projects in a cohesive fashion. In this regard, Dinsmore and Cabanis-Brown point out that, "Most executives are aware of the need for drastic change in multiproject management practices, but many place the emphasis in the wrong place. Unfortunately, a great deal of such investment is misdirected into multiyear efforts to implement software tools and time sheets before dealing with the highest leverage points" (2011, p. 315).

There are three discrete roles that organizations must formally define in order to develop an effective project portfolio management system as follows:

Game of Deception Game Theory Research Proposal

… ¶ … Game of Deception (Game Theory)

Developing a Game of Deception using Game Theory

Game theory is the theory of independent and interdependent decision making that is concerned with organizational decision making wherein the outcome involves the types of decisions made by two or more autonomous players, one of which may be nature itself, and in which no single decision-maker has complete control over the outcomes (Kelly, 2003). As this author points out, "Obviously, games like chess and bridge fall within the ambit of game theory, but so do many other social situations which are not commonly regarded as games in the everyday sense of the word" (Kelly, p. 1). Although game theory has been extended into a number of human endeavors in an…. [read more]


Exchange Rate Volatility and International Term Paper

… There are many factors that the PPP model fails to consider and it appears that the PPP model only works in long-term, highly inflationary economies. Even these applications have been criticized. There are many later versions of this theory that consider nonlinear and linear economic models. The PPP theory continues to suffer from a lack of conclusive empirical evidence. Therefore this theory is perhaps the least widely accepted of the economic models for predicting exchange rate volatility.

Further work needs to be done on real exchange rate behavior as opposed to theoretical exchange rate behavior in order to devise a better and more realistic working model of the PPP. In addition the proper circumstances must exist in order to apply the PPP model. It is…. [read more]

Golden Ratio:

The golden ratio is acknowledged as the divine proportion golden mean, or golden section is represented as a number mostly confronted while considering the ratios of distances in simple geometric diagrams like pentagram, decagon and dodecagon. It is indicated by the symbol 'phi'. The concept 'golden section' was first used by Martin Ohm in the 1835 in his book Die Reine Elementar-Mathematik. The first ever English use was seen in the article of James Sulley in 1875 which appeared in the 9th edition of the Encyclopedia Britannica. The symbol 'phi' was first used by Mark Barr at the inception of the 20th century in commemoration of the Greek sculptor Phidias, who was an extensive user of golden ratio in…. [read more]


Music Education or Cross Platform Development Term Paper

… Music Education or Cross Platform Development

Pitch is commonly mistaken for being a term which is analogous to frequency; however, pitch is actually based on perception. Pitch is the human perception of the frequency of a musical note. (Heresiarch 2005) While pitch is related to the frequency, or physical rate of vibration in a sound wave, it is distinctly different.

The current standardized relationship between pitch and frequency is that the note a above middle C. sounds like a 440 Hz tone. In a musical context, the exact frequency of a note is far less important than its relationship to other notes. Numerous systems exist for defining the relationship between notes in a scale, usually involving a fixed frequency ratio between successive notes. The chromatic…. [read more]


Nonlinear Aerostatics Stability Analysis of Suspension Bridges Literature Review

… Su, Luo & Yun (2010) performed an aerostatic reliability of bridges with long spans. According to their study, the response surface Monte Carlo method (RSMCM) is suggested to be suitable for the analysis of the reliability of both the aerostatic stability and the aerostatic response for various types of long-span bridge structures. In these bridges, the nonlinear effects that come about as a result of the geometric nonlinearity as well as loads that are dependent of deformation are taken into due consideration. In their study, the geometric parameters, aerostatic coefficients of the girders used on the bridge as well as the parameters of the materials used are treated as random variables. The response surface Monte Carlo method (RSMCM) is pointed out to possess a higher…. [read more]

The work of Applegate, Bixby, Chvatal and Cook (2007) entitled: "The Traveling Salesman Problem" states the following: "Given a set of cities along with the cost of travel between each pair of them, the traveling salesman problem, or TSP for short, is to find the cheapest way of visiting all the cities and returning to the starting point. The "way of visiting all the cities" is simply the order in which the cities are visited; the ordering is called a tour or circuit through the cities." (2007) This exercise which sounds modest according to Applegate, Bixby, Chvatal and Cook (2007) however it is

Designing Good Deceptions in Defense of Information Systems Term Paper

… Designing Good Deceptions in Defense of Information Systems" by Neil C. Rowe

Although computer systems and their security procedures have become more sophisticated in recent years, so too have those who would seek to attack these networked systems. One of the fundamental features of past computer-based systems has been the ability of the hacker to rely upon the information the computer system provided; in other words, computers may break down or they may be programmed incorrectly, but "computers never lie." The author, though, suggests that it is time for them to start lying, at least when it comes to dealing with those who would try to overcome the system's security. In fact, Rowe makes the point that the hackers' own interactions with the computer system…. [read more]
