1.

Over a three week (21-day) scheduling period, each unit will be scheduled for seven days. Normal staffing requires 186 firefighters to be on duty every day. Thus, each unit needs to provide staffing for 7*186=1302 firefighter days. During a three week period, each firefighter provides 6 days of service. Therefore, Base no of firefighters needed by each unit=1302/6 = 217 Base no of firefighters needed by each unit=217.

2.

Using the normal distribution, Z value corresponding to probability of 0.3548= - 0.3722 Optimal no of additional firefighters based on given distribution: Q*= μ+Ζσ μ=20 σ=5 Ζ=0.3772 Thus, Q*=20-0.3772(5) =18.14 Using minimum cost criteria, 18 firefighters should be added in each unit in order to cover daily absences.

3.

On a given day, what is the probability that Kelley-day firefighters will be called in to work overtime? Optimal probability that demand will exceed Q*: P (Demand>Q*) =1-((Cu/ (Cu +Co)) P (Demand>Q*) =1-0.3548 = 0.6542 the probability that Kelley-day firefighters will be called in to work overtime=0.6542

4.

Based on the three-unit organization, how many firefighters should be assigned to each unit? What is the total number of full-time firefighters required for the River City Fire Department? Firefighters for each unit=Base no of firefighters + Additional firefighters =217 +18 =235 2

...Quantitative marketing research is the application of quantitative research techniques to the field of marketing. It has roots in both the positivist view of the world, and the modern marketing viewpoint that marketing is an interactive process in which both the buyer and seller reach a satisfying agreement on the "four Ps" of marketing: Product, Price, Place (location) and Promotion. As a social research method, it typically involves the construction of questionnaires and scales. People who respond (respondents) are asked to complete the survey. Marketers use the information so obtained to understand the needs of individuals in the marketplace, and to create strategies and marketing plans.

...BUSN311-1302A-02 Quantitative Methods and Analysis Unit 3 DB Leah Murray May 13, 2013 While determining a sample size, the researcher would first need to know how many people, otherwise how many animals would be required because if you do not have enough sample size then it will have an cause on the general study conclusion (2006). The arithmetical power, P level as well as the treatment including the error variability is the factors otherwise; it would be the parameters in order to aids the researchers with choosing the correct sample size for the study (2006). The arithmetical power informs us how powerful the contributing people otherwise the animals in the study is going to be affected with the treatment that will be given to each of them. The P level will assist the researchers in determining the probability for any variation within the topic throughout the study (2006). At last, the investigators have determined the accurate sample size established as to whether or not the remedy predictability for the study is larger than the error predictability. In which it means that some more participants might be needed for the study if the researchers determine to facilitate the affect of the treatment that would happen to be smaller than the error variability (2006). Creative researcher systems as well as the raosoft are survey system companies that provides calculators in order to decide the model size intended for the research investigation. However, for a sample size...

It’s mean that the relationships between Cousework mark and Exam mark is weak. For example, if a student got a high mark on his/her Cousework, it does’t represent that he got a high exam mark. Sheet 2c I have used the function “SUMIF”, in order to show how many students are coming from Africa, Asia, Europe, North America, Oceania & South America. This funtion can help me to choose those data I would like to summarise.Choosing a pie chart to represent my findings because a pie chat can shows the percentage of total for each category. Pie charts are good when we are showing the relative proportion of numbers that add up to a total. They are good for a single series of data and show a good qualitative view of the data Sheet 3c In spreadsheet applications, absolute reference is a reference to a particular cell or group of cells that does not change, even if you change the shape or size of the spreadsheet, or copy the reference to another cell. Absolute cell references are particularly useful for referencing constant values. Relevant references is use when we are calculate formula with a side by side value, then relevant references will be very useful in this stage. Sheet 4c According to the diagrams, the price...

National, Corporate and Functional Influences. This paper aims to establish the analysis of a unique international data set in four host countries like Canada. Ireland, Spain and UK. The study examines the argument that various, rather than single, proof are required to understand the factors promoting or retarding the diffusion of human resource practices within multinational companies. Multinational companies are progressively powerful and effective in Europe and worldwide. They are the main factor of the world and regional economies. MNCs are familiar with the sharing of organizational practices to foreign subsidiaries with the rest of the company. Organizational practices can be shown as important resources and abilities to produce and develop through the firm. “The key part of MNC’s is the diffusion of human resource practices to develop at the international level at the diverse capabilities and knowledge that they possess at subsidiary level.” The article examines the diffusion of HR practices from the......

...Quantitative Methods in Management is generally a practical field and can be applied in different areas like Manufacturing, Environmental Planning, Engineering and Construction which is the field of my profession as an Architect. The subject offers a scientific and systematic approach to problem solving and decision making. The use of mathematical analysis helps a decision maker like me, to be able to understand the problems I’m facing and provide a tool in making informed and reasoned judgments. One example on how the subject can help me is for putting mark ups on BIDS which we normally use in construction. The different methods shown in the subject especially in chapter 4 sample problem(4-13) in the book thought me on how to evaluate expected value of profit on different values of additional cost and evaluate which value can give me the best probability of winning the bid and getting the highest profit possible. Since one of the objectives of the subject is to develop analytical frame of mind, it will be an essential tool in project management which includes decision making. It will make Project Managers like me to be explicit in analyzing conditions associated with future decisions and in determining the outcome of different alternatives. For example in my case, I can now evaluate the pros and cons of renting exhibitions stands against building our own for the company. I can now consider which will be more profitable for the company considering all the factors......

...Question 1: After consider the requirements, we decide to use Mean-Variance preferences method to calculate the utility we can get from investing four stocks: DBS, SPH, GE, SIA. We know the equation: Ur= μ-γ2 Varri=μ- γ2σi2 We can decide weight of four stocks by maximizing the utility of the portfolio. (N=4, T=232) So we suppose: 1. The best portfolio is the one that satisfy owner most, which means have the maxi utility. 2. The owner is afraid of risk, and the risk aversion is measured by γ, γ=3 3. The portfolio will be hold for one year. From equation: Rate=R1-R2R1 We can get return rates of four stocks in different periods since Jan-96 (See sheet 1), and the mean return rates μ for the four stocks are: DBS=0.10814638, SPH=0.0733264, GE=0.12002196, SIA=0.06982988 And we can get the Covariance Matrix: 0.105279399 0.041817263 0.05022109 0.0565126810.041817263 0.062596535 0.025656805 0.0373403140.05022109 0.025656805 0.109059667 0.0386166250.056512681 0.037340314 0.038616625 0.065556537 A= 21.372.

...Jet Copies Case Problem Alex B. Wilson Professor Henry Grimm Quantitative Methods-MAT 540 February 12, 2012 Strayer University-Allentown Campus Jet Copies Case Problem 1 If you assume that the number of days needed to repair a copier is random, you can generate a random number using the Excel RAND function which I denoted r2 between 0 and 1. If 0 < r2 < 0.2 then it takes 1 day 0.2 < r2 < 0.65 then it takes 2 days 0.65 < r2 < 0.90 then it takes 3 days 0.9 < r2 < 1 then it takes 4 days 2 The probability distribution of the random variable varies between the times of 0 to 6 weeks, with the probability increasing as time goes on. This can be approximated by the function f(x) = x/18 for 0 < x < 6 Therefore, the distribution function is f(x) = x-square divided by 36 for 0 < x < 6 If we set this equal to another random number r1 that is between 0 and 1 then R1 = x-square divided by 36 which results to x = 6√ r1 3 Since the number of copies sold per day is a uniform probability distribution between 2000 to 8000 copies, I made r3 a random number between 2000 to 8000. To get the amount of business lost on a particular day, I take r3 X (repair time), and the lost revenue is then equal to 0.1 X r3 X repair time, since they charge $0.10 per copy. 4 After running the simulation, I got the following results: Repair Distribution P(x) | Cumulative | Repair time | 0.2 | 0.000 | 1.000 | 0.45 |......

...James W. Taylor February 2012 Imperial College EMBA 2012 Quantitative Methods Individual Assignment This assignment consists of two parts. Part A is worth 50% of the marks, and Part B is worth the remaining 50%. Your report for the two parts should consist of no more than 1,500 words. Part A – Blanket Systems Blanket Systems is developing and testing a new computer workstation, OB1, which it will introduce to the market in the next 6 months. OB1 will be sold under a three-year warranty covering parts and labour. The company has decided to subcontract the service support for the warranty and has entered negotiations about the support contract with Fixit Inc. Fixit has proposed two different pricing schemes for the subcontract. The first involves the payment of a fixed fee of $1,000,000 and the second a variable fee of $250 per workstation sold, subject to a minimum fee of $350,000. Under both schemes, the payment will be made one year after the introduction of the workstation to the market at which point the product will be replaced by newer models not covered by the warranty service subcontract. At the moment, there is uncertainty about the sales potential of the new workstation. Sales of OB1 are expected to come from two sources: (i) the successful closure by senior management of a major purchase of 2000 units by a long standing customer, (ii) the efforts of regional sales offices. Given the state of the negotiations with the long-standing customer, the current estimate......
