and calculations. II. Background The Florida Motor Fuel Marketing Practices Act (MFMPA) determines motor fuel cost for non-refiners as the actual invoice price‚ including associated freight charges and taxes‚ plus direct labor and reasonable rental value of the outlet attributable to fuel sales. The invoice price by its nature can be directly attributable to each grade of gasoline at a per

Logic to Ladder Diagram There are some methods to do PLC programming. The programming methods can be with Logic Ladder Diagram‚ mnemonic (statement list)‚ and / or function block diagram. One of the PLC programming methods that are very commonly used programming using PLC ladder diagram. The method is practical and easy to understand. The programmer in charge of writing a program should describe an electronic switch circuit. It can be designed to perform the conversion of electronic circuits that

The Hertzsprung-Russell Diagram or‚ the H-R Diagram for short‚ is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern‚ which in fact is quite interesting. The H-R Diagram is named for the two astronomers‚ Ejnar Hertzsprung and Henry Russell‚ who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. <br><br>One key

Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

1. What was the utilization achieved by CRU in 1996? Utilization = Inventory on rent / Inventory owned Inventory on rent = 1‚000 units per week x 8 weeks = 8‚000 Inventory owned = 8‚000 + 500 + 1‚500 + 1‚000 + 905 + 500 + 2‚000 = 14‚405 Utilization = 55% (8‚000 / 14‚405) Customer Receiving Status 24 Status 40 Status 41 Parts (order forms in Que) Supplier (waiting for parts) Status 42 Status 20 Throughput (units/week) 1000 1000 700 405 405 405 405 405 1000 (1000 x 70%) [(1000

DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations

Before starting this homework assignment‚ please review the AIB simulation in this week’s Lecture. This simulation will provide you with an understanding of how to create a network diagram‚ and how to do a forward and backward pass to determine the ES‚ LS‚ EF‚ LF and slack (float). You will also learn how to determine the duration of the project‚ and the critical path. In this homework assignment‚ you will be working through four Activity In Box (AIB) problems. Using the activity‚ duration‚ and

Making Performance Appraisals Legally Defensible Lawsuits challenging the legality of the specific performance appraisal systems and resulting personnel actions have left scores of human resource manager asking themselves‚ “Will may organization’s performance appraisal systems stand up in court? Manager needs specific criteria for legally defensible performance appraisal systems. After studying the verdicts in 66 employment discrimination cases in the United States‚ one pair of researchers found

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

Using Data Flow Diagrams Data flow diagram is used by system analyst to put together a graphical representation of data processes throughout the organization. It depicts the broadest possible overview of system inputs‚ processes‚ and outputs. A series of layered data flow diagrams may be used to represent and analyze detailed procedures in the larger system. By using combinations of only four symbols‚ the system analyst can create a pictorial depiction of processes that will eventually provide
