The report takes an in-depth look at the technical elements and algorithms used in these protocols, such as Bellman Ford, DUAL, and the Dijkstra Algorithm; and how these algorithms are used to calculate the routing metric. The report also discusses the fact that EIGRP is the most desirable protocol to use on Cisco based routers, while OSPF can be used across different router manufacturers. While looking at the technical considerations that are needed in choosing a routing protocol for a desired network the report will also look into the CPU/memory requirements, and how difficult the protocol is to install and maintain...

...1. Introduction Routing Information Protocol (RIP) is a special type of protocol also known as routing protocol and the main purpose of the protocol. This protocol is to provide communication between different routers so they can exchange information or how to find the best path to a given destination. There is Routing Information Protocol version 1 (RIPv1) and Routing Information Protocol version 2 (RIPv2). RIPv1 uses classful and it sends routing updates as broadcast messages and does not support VLSM. Meanwhile, RIPv2 is created to overcome the RIPv1 problems which is uses classless and it can send multicast messages and also supports VLSM. It have many features between these two routing protocol. Other protocol is Enhanced Interior Gateway...

...Chapter 6 Allocating Resources to the Project This chapter extends the previous one on scheduling into the area of allocating resources among the activities of a project, or among multiple projects competing for the same resources. The chapter begins with a discussion of expediting project completion times and highlights that by selectively choosing which activities to crash and by how much, we can determine the minimum cost for all possible project completion time. The use of Excel’s Solver optimization routine to facilitate this analysis is also presented. Next, the chapter moves on to the topic of resource loading and in particular highlights the problems of over scheduling resources. The topics of resource leveling and resource allocation naturally follow in the subsequent sections. Finally, the chapter concludes with an overview of several of the concepts Goldratt raises in his provocative book Critical Chain. Cases and Readings A case appropriate to the subject of this chapter is: Harvard: 9-613-020 Space Constructors, Inc. This 3-page case involves a simple project where partial crashing has already been planned but more, and less, crashing is also to be considered. The network has some special characteristics that offer some worthwhile lessons for the student. Answers to Review Questions 1. Given the fact that a project’s resource requirements are clearly spelled out in the project’s action plan, why are PMs so concerned with resource...

...2. Discuss the red flags for a small business related to business failure and bankruptcy. The high failure rate of small business start-ups is a major concern for many entrepreneurs, reason why they should be sensible to red flags in the business and the environment that may be early warning signs of trouble. Before engaging in new ventures entrepreneurs have to make sure that they are choosing a profitable sector, have enough cash reserves, and anticipate the price, the competitors, and the changing behaviors of consumers. Also, it is important that the entrepreneurs pay close attention to following red flags because they can be signs of bankruptcies: Finances are becoming so lax that no one is able to explain how the money is being spent. Directors cannot document or explain major transactions. Large discount are given to customers to enhance payments because of poor cash flow. Contracts below standards amount are accepted to generate cash. Bank request subordination of its loans. Key personnel leave the company. Materials to meet orders are lacking. Payroll taxes are not being paid. Suppliers demand payments in cash or in advance. Complaints from customers regarding the quality of product, service, or price. When an entrepreneur sees any of these signs he should immediately seek the advice of a Certified Public accountant (CPA) or an attorney, because generally unrelated one problem often lead to another one. Many young entrepreneurs...

...Chapter 10 Product Liability I. Definition of Product Liability Manufacturers and anyone in the chain of product distribution can be legally liable for defective products that cause injury to the purchaser, a user or bystander, or their property. Most states have adopted strict product liability, whereby an injured person may recover damages without showing that the manufacturer was negligent or otherwise at fault without a contractual relationship. II. Theories of Recovery The primary theories on which a product liability claim can be brought are breach of warranty, negligence, and strict liability. A. Breach of Warranty In a warranty action, the question is whether the quality, characteristics, and safety of the product were consistent with the implied or express representations made by the seller. 1. UCC Warranties may be either express or implied for merchantability or fitness for a particular purchase, as set forth in Chapter 8. 2. Privity of Contract Breach-of-warranty is based on contract law. Generally, an injured person to recover for a breach of warranty, he must be in a contractual relationship (privity) with the seller (a consumer or buyer of the product) and prevents recovery from bystanders not in privity with the seller. B. Negligence To prove negligence in a product liability case, plaintiff must show defendant did not use reasonable care in designing or manufacturing its product or in providing adequate warnings...

...CHAPTER 6 Allocating Resources to the Project In this chapter we consider the problem of allocating physical and human resources to projects.* The physical and human resources are granted to and used by the project in order to meet the project’s performance objectives. The amount of resources that can be allocated, of course, depends on the timing of the allocation as well as on the total supply of resources available for allocation. Mainly, resource allocation concerns how we allocate specific, limited resources to specific activities (or projects) when there are competing demands for the same limited resources. Projects compete with each other for the same resources in two different ways. First, consider a resource that is limited but is not consumed when used, the services of a specific technical specialist for instance. The problem here is which project gets to use the resource first and which must wait. Second, consider a resource that is limited and is consumed when used, a specific chemical reagent for instance. In this case, the second project may have to wait until more of the reagent can be purchased and delivered. In both cases, the project that must wait may suffer a schedule delay that makes it late. Just as projects may compete for resources, different activities of the same project may compete. Two or more concurrent activities might require the same personnel, or equipment, or even work space. One activity will be given priority, and the other(s) must wait. In...

...Case study An analysis of 3M, the innovation company Introduction Any review of the literature on new product development and innovation management will uncover numerous references to 3M. The organisation is synonymous with innovation and has been described as ‘a smooth running innovation machine’ (Mitchell, 1989). Year after year 3M is celebrated in the Fortune 500 rankings as the ‘most respected company’ and the ‘most innovative company’. Management gurus from Peter Drucker to Tom Peters continually refer to the company as a shining example of an innovative company. This case study takes a look at the company behind some of the most famous brands in the marketplace, including Post-it® Notes. It examines the company’s heritage and shows how it has arrived at this enviable position. Furthermore, the case study attempts to clarify what it is that makes 3M stand out from other organisations. Background Originally known as the Minnesota Mining and Manufacturing Company, with its headquarters in St Paul, Minnesota, 3M was established in 1902 to mine abrasive minerals for the production of a single product, sandpaper. From these inauspicious beginnings, the company has grown organically, concentrating on the internal development of new products in a variety of different industries. The latest review of the company’s position reveals that it manufactures over 60,000 products, has operations in 61 countries, employs 75,000 people and has achieved an average year-on-year growth...

...evaluation and review technique) and CPM (critical path method), are available to assist the project manager in carrying out these responsibilities. These techniques make heavy use of networks (as introduced in the preceding chapter) to help plan and display the coordination of all the activities. They also normally use a software package to deal with all the data needed to develop schedule information and then to monitor the progress of the project. Project management software, such as MS Project in your OR Courseware, now is widely available for these purposes. PERT and CPM have been used for a variety of projects, including the following types. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Construction of a new plant Research and development of a new product NASA space exploration projects Movie productions Building a ship Government-sponsored projects for developing a new weapons system Relocation of a major facility Maintenance of a nuclear reactor Installation of a management information system Conducting an advertising campaign PERT and CPM were independently developed in the late 1950s. Ever since, they have been among the most widely used OR techniques. The original versions of PERT and CPM had some important differences, as we will point out later in the chapter. However, they also had a great deal in common, and the two techniques have gradually merged further over the years. In fact, today’s...

...HEALTH EDUCATION RESEARCH Theory & Practice Vol.21 (Supplement 1) 2006 Pages i19–i32 Advance Access publication 31 July 2006 Improving measurement in health education and health behavior research using item response modeling: comparison with the classical test theory approach Mark Wilson*, Diane D. Allen and Jun Corser Li Abstract This paper compares the approach and resultant outcomes of item response models (IRMs) and classical test theory (CTT). First, it reviews basic ideas of CTT, and compares them to the ideas about using IRMs introduced in an earlier paper. It then applies a comparison scheme based on the AERA/APA/NCME ‘Standards for Educational and Psychological Tests’ to compare the two approaches under three general headings: (i) choosing a model; (ii) evidence for reliability—incorporating reliability coefficients and measurement error—and (iii) evidence for validity—including evidence based on instrument content, response processes, internal structure, other variables and consequences. An example analysis of a self-efficacy (SE) scale for exercise is used to illustrate these comparisons. The investigation found that there were (i) aspects of the techniques and outcomes that were similar between the two approaches, (ii) aspects where the item response modeling approach contributes to instrument construction and evaluation beyond the classical approach and (iii) aspects of the analysis where the measurement models had little to do with the analysis or outcomes. There...
