IT521 Decision Support Systems
Kaplan University

Introduction

Decision support system methodologies have existed for almost 50 years, originating in 1965 (Sprague & Watson, 1993). The evolution of what is now more commonly referred to as decision support, sans the ‘systems,’ began with research by Michael Scott Morton (Sprague & Watson, 1993). Decision support can encompass computer systems, or management information systems (MIS), or just work systems that involve people and processes, and the improvement of everyday operations (Sprague & Watson, 1993). What began as an unstructured science of facilitating organizations to make decisions has evolved into newer concepts called automated decision systems (ADS) (Turban, 2011). Decision support systems are used by organizations to facilitate decision-making by management that is either strategic, tactical or operational (Turban, 2011). Within the decision support systems arena, there are three main types of decision support systems: structured, semi-structured and unstructured. By definition, there are 4 phases that evolve in the identification of determining whether a decision support system is unstructured, semi-structured or structured (Turban, 2011). These phases include intelligence, design, choice and implementation (Turban, 2011). In addition, there are five main types used to facilitate the decision-making process within a decision support system model. These include decisions that are driven by communications, data, documents, models and knowledge (Turban, 2011).
This document will assess two cases studies to determine the management type of decision support system, whether the decision support system is unstructured, semi-structured or structured, and what drives the decisions within the decision support model.

Case Study 1 The first case study is related to a business

...placed under construction on 10/28/2015. The construction area was from mile marker 213 to mile marker 236 with significant crashes causing interstate blockage daily. There was a major increase in the number of crashes documented due to various issues within the construction area. After consulting with the area supervisor, I was authorized to develop a crash reduction plan for this section of highway. I identified issues within the construction zone and met with personnel from TxDOT, Texas Sterling, Webber and various other contractors to address the problem issues; to include: water drainage, tapers, extruders, speed limits, lane closures, and worker safety. A HEAT map and crash data was pulled. Day patrols were increased, a UCRP (Drone Unit) was strategically placed, surge operations and multiple laser task forces were conducted. In turn, major crashes were reduced, construction zone safety was increased, and traffic flow was improved; while teamwork and overall area morale were strengthened. During a declared disaster in Navarro County due to major flooding, I was selected to serve as the contact person for field operations. I advised the Chain of Command as it became necessary to close Interstate 45 due to Richland Creek flooding at the 220-milepost. I placed Troopers south of the creek due to the next crest. I informed the command post of locations to station Trooper so that traffic on the interstate could be shut down. I was able to give the Chain of Command alternate...

By reviewing this window System Properties, you will learn the exact Operating System the computer runs. The Operating System is listed under “Windows edition”. Then you will see the title “System”, the speed of your processor is listed, the amount of Installed memory (RAM), and then the System type. Then you will have the title “Computer name, domain, and workgroup settings”. All of these details are very important when using the computer. The Operating System (OS) is the most essential software on the computer. The OS manages the hardware and software. The Operating System gives direct access to the storage, central processing unit (CPU), and memory, so that different programs can work properly. Without the OS the Computer will operate properly. The operating system determines what your computer can or cannot actually do because each OS has different features, options, applications, compatibilities and even the user interface may change. My current computer has Windows 8.1 as the operating system. Within Windows 8.1 the user interface is much different than the previous Windows 7. After, the first initial installation of Windows 8 certain programs did not work and had to be updated in order to be compatible with the system, even though they originally worked in Windows 7.

...Unit 1 Assignment 1 Integrated Circuit Technology A motherboard is the backbone of the personal computer, it transfers information and power to all the other components. The motherboard is the largest board inside of the computer that contains the basic input and output system that allows every component to communicate with one another. Attached to the motherboard is a chip comprised with dozens of pins called the central processing unit. Along with the CPU attached to the motherboard is the dual-inline memory modules a part of the random access memory. RAM is the most common type of memory used another type is ROM, read only memory, which stores data onto metal disc within the device. The operating system manages the hardware resources and provides a place to run programs. The last components of the personal computer are the tower and the human interface devices. The tower holds all the components that make up the computer except for the HID which are located outside of the computers tower. The main purpose of the HID’s are to help us interact with the computer, a few examples are the keyboard, mouse, monitor, video camera and speakers. You put together the Motherboard, CPU, RAM, ROM, OS, Tower, HID’s add a power supply and you have a basic personal computer.

...740 words. Question 3: “Describe the function of the following Docker commands and briefly explain the purpose of each of the parameters. docker run –d –p 8080:5000 –v $(pwd)/data:/data –name container1 lab4 Docker is a software containerization platform, that runs processes in isolated containers. The docker run command is used to define the containers resources at runtime. When the command is run, the container process is isolated. It is separate from the host itself. The –d command is an option run by Docker to communicate whether the container should be run in “detached” mode or in the “default mode”. The –d command signifies that the container should be run in detached mode, meaning the container will be run in the background. The next option used is –p. This is used to publish all exposed ports to the host interfaces. Docker, in turn, ‘binds’ each of the exposed ports to a host port, addresses of the published ports are 8080:5000. The –v command mounts the current working directory into the container. The –v command can be used multipule times to mount datat volumes. Here it is mounted once. The pwd command prints the working directory i.e. data:/data. The –name command assigns the name container1 lab4 as the container name. docker exec –it A637jd9dja /bin/bash The docker command docker exec runs a new command in an already running container.

...Part 1 Question 1: What is computer architecture? Computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. The area includes in computer architecture has the fundamental physical components that constitute a computer system (hardware), the kind of instructions or language the computer can understand, and the underlying computer technology that manipulates these instructions (sometimes referred to as microarchitectures). Question 2: How does data represented / stored / processed in computer? Computer use binary digit as 0 and 1 to store data. Binary digit or called bits is the smallest unit of data in the computing. Not only that, all data represented by made up of binary digits. For example, 01000001 could be a number 65, or character as ‘A’ or a color in an image. The data processed through Boolean Logic. It is a form of algebra in all values are reduced to either TRUE or FALSE as 1 and 0. So that can be formed up a group of binary digit.

The previous owners landscaped part of the backyard, but she would like help in landscaping the rest of it. Andy has the potential to be a great landscaper, but isn’t very good at math and will need Jourdan’s help before he can get started. Jourdan’s yard is 200 feet long, and its width is 75% of its length. The portion of her yard that does not need to be landscaped is along the shortest part of the yard and is 10% of the width of that part of the yard. Jourdan would like to put in grass, but does not want it to take up more than 1/25 of the space in her yard (space is in ft2). What is the largest area the grass can take up? If Jourdan’s grass takes up that much space and each grass piece 4ft wide, how long are they? Jourdan would like to add some brick to her patio. If each of those bricks is 6 inches long 3 inches wide. She only needs to cover 15 square feet, how many bricks does she need? We have discovered that the length of her yard is 150 feet.

There are some minor competitions but don’t stay on the market for long. The system bus for the CPU is also known as the Front-side bus as it inserts the CPU and has a 64 bit data pass. In the CPU theirs a controller that controls communication between the motherboard and other components with the CPU. The ALU is responsible for performing complex calculations. Communications between the controllers and the ALU’s uses a 32 bit wide internal data bus. A processor is usually measured in GHz. A system Bus is usually measured in MHz and has limiting factors of speed. The multiplier is the ratio between processor and the System bus. The system bus speed x multiplier equals the processor speed. CPU manufactures have come up with different ways to make the CPU work faster. Two multi-processing requires multiple processors (In other words your system must be designed to support more than one CPU on a single motherboard). Dual Core Processors have been recently developed, that means incorporating multiple processors with multiple ALU’s inside a CPU. These ALU’s process their information individually. There’s two cache memory’s which are SRAM and DRAM. SRAM is also called Static RAM, it is faster and more expensive then DRAM, it holds memory without being refreshed and DRAM must be refreshed. There are three types of RAM which are L1 cache, L2 cache, and L3 cache...
