Operational Research

What is Optimization? Optimization problem: Maximizing or minimizing some function relative to some set, often representing a range of choices available in a certain situation. The function allows comparison of the different choices for determining which might be “best.” Common applications: Minimal cost, maximal profit, best approximation, optimal design, optimal management or control, variational principles. Definitions of Operational Research ·          “OR is concerned with scientifically deciding how to best design and operate man-machine system usually requiring the allocation of scare resources.” – Operations Research Society, America ·          “OR is essentially a collection of mathematical techniques and tools which in conjunction with system approach, are applied to solve practical decision problems of an economic or engineering nature’’. – Daellenbach and George ·          “OR utilizes the planned approach (updated scientific method) a

Steps 1. Go to https://console.developers.google.com 2.  Create a new Project 3. Go to  API and select Analytics API  (used in this e.g.) 4. Go to Consent Screen and fill the appropriate product name and save 5. Go to credentials and creat a new client ID Make sure u enter the website URL properly 6. Now run the following R script R Script require(RGoogleAnalytics) client.id="xxxxxxxxxxxxxxxxxxx" client.secret="xxxxxxxxxxxx" token <- auth="" client.id="" client.secret="" p="">ValidateToken(token) query.list <- init="" p="" start.date="2014-01-01">                   end.date = "2014-02-10",                    dimensions="ga:date,ga:pagePath,ga:hour,ga:medium",                    metrics = "ga:sessions,ga:pageviews",                    max.results=500,                    sort="-ga:date",                    filters="ga:mediu

JavaBeans

JAVA BEANS JavaBeans can be understood as java classes that can be easily reused and composed together into an application. Any java class that follows certain design conventions can be used as a javaBean component. JSP directly supports javaBean components using JSP elements. One can easily create and initialize the value of the Beans and set their properties. ·        useBean:    A JSP action element <jsp:useBean> initiates a JavaBean object into the JSP page.    Syntax: <jsp:useBean id=”object_name” class=”class_name” scope=”page|request|session|application” | /> ·        setProperty:  The <jsp:setProperty> action tag assigns a new value to the specified property of the specified bean object. Syntax: <jsp:setProperty name=”obj_name” property=”prop_name”  value=”prop_value”/> ·        getProperty:  The <jsp:getProperty> action element retrieves the value of the specified property of the specified bean ob
