Logistics: The Missing Link in Blend Scheduling OptimizationAlkis Vazacopoulos
油
This document discusses logistics scheduling optimization for blending liquids. It begins by introducing blending and describing logistics scheduling as the "coarse-tune" that determines quantity and logic details, while quality scheduling performs the "fine-tune." It then provides examples of key logistics constraints like minimum/maximum run lengths. The document emphasizes that ignoring logistics leads to suboptimal schedules. It proposes various metrics to quantify non-compliance with logistics constraints. Finally, it presents a framework to trade off quantity and quality using "logistics isotherms" and argues explicit logistics scheduling can improve this trade-off relationship.
This document outlines three data analysis techniques checking, clustering, and componentizing utilized by Industrial Gorihm LLC for real-time decision-making applications. It details data checking routines that ensure data integrity, fuzzy c-mean clustering for identifying process modes, and principal components analysis for dimensionality reduction in data. Additionally, a new approach called principal component regression optimization (PCRO) is introduced to enhance the efficiency of regression analysis compared to traditional methods.
The document discusses the international expansion plans of Acme Manufacturing Company into either Germany or South Africa. It analyzes the advantages and disadvantages of creating a new manufacturing facility, or "Greenfield," in each country.

The document provides recommendations for project management including setting up frequent assessment and feedback, planning incrementally in small units, and using an agile framework with sprints, planning sessions, sprints for work, and retrospectives to continuously improve. It also recommends making small, frequent commits to source control and using test-driven development.
Advanced Production Accounting (APA) uses statistical data reconciliation and regression to clean past production data when processes are assumed to be at steady-state. It defines a simultaneous mass and volume problem with density. This is depicted in an oil refinery flowsheet using the unit-operation-port-state superstructure (UOPSS). Key differences from prior work are that UOPSS uses "ports" to represent flows, requiring fewer quality measurements. Industrial Modeling Framework (IMF) implements the mathematical formulations using IMPRESS modeling language and solvers like SECQPE and SORVE for data reconciliation problems. IMFs provide pre-configured models for industrial projects.

This document provides an overview of the Twenty First Century Science GCSE course, outlining the modules covered in each subject area of Biology, Chemistry, and Physics, as well as explaining the structure of assessment, command words commonly found in exam questions, and how the modules fit together across the different GCSE qualifications.
The document discusses human eye color and genetics. It begins by describing different genotypes for eye color such as homozygous dominant (BB), heterozygous (Bb), and homozygous recessive (bb). It then asks the reader to determine the phenotypes (eye colors) associated with these genotypes. The document goes on to explain how to use a Punnett square to determine the chances of offspring inheriting different eye colors based on the parents' genotypes. It provides an example of a heterozygous mother and homozygous recessive father and walks through setting up and solving a Punnett square to predict the ratio of offspring with brown vs. blue eyes.
Both parents are heterozygous for achondroplasia (Dd). A Punnett square shows that there is a 25% chance of a child being homozygous dominant (DD) and dying before age 1, a 50% chance of being heterozygous (Dd) and having dwarfism, and a 25% chance of being homozygous recessive (dd) and being normal.
This document provides an introduction to the Twenty First Century Science GCSE course, outlining the structure of the modules and assessments, including the topics covered in each module for Biology, Chemistry, and Physics, how the modules fit together, and the format and requirements of the GCSE exams. It also defines common command words used in exam questions to help students understand what is being asked of them.
The three articles discuss particulates in the air, genetic mapping, and observations of the night sky. Particulates are small solid or liquid bits that float in the air and come from both natural and human sources like burning fossil fuels. They can affect climate by scattering solar radiation and absorbing heat, and harm health. Genetic mapping allows prediction of future health risks but raises ethical issues about how to handle that personal genetic information. Early observations of the night sky helped discover that nebulae are galaxies and the universe is much larger than originally believed.
The document discusses counting particles in atomic nuclei and describing radioactive decay. It provides examples of carbon-14 and carbon-12 isotopes and asks the reader to count the protons and neutrons in each. It also discusses alpha and beta decay and asks the reader to write nuclear equations showing how each type of decay changes the nucleus.
The document discusses radiation safety and properties of different types of radiation. It explains that people working with radioactive materials should follow the ALARA principle to keep radiation exposure as low as reasonably achievable. Alpha radiation has a short range but is very ionizing, while gamma radiation can travel farther but has low ionizing power. Gamma radiation is used to sterilize surgical equipment and food because it kills living cells.
Radiation is found naturally all around us in background radiation from sources like rocks, buildings, food, and drink. Certain rocks contain radioactive elements like radon that produce ionizing radiation, which can damage living cells by leaving them unaffected, slightly damaged but self-repairing, causing DNA damage and cancer, or causing cell death. The average yearly radiation dose a person in the UK receives is about 3 millisieverts, which measures the amount of radiation exposure. Irradiation occurs when a radiation source is outside the body, while contamination is when the source enters the body.
Radioactive decay occurs when the nucleus of an unstable atom decays and changes. There are three types of radioactive decay: alpha decay which emits a helium nucleus, beta decay which converts a neutron to a proton and emits an electron, and gamma decay which emits electromagnetic radiation without changing the nucleus. Radioactive isotopes are used in medical scans and treatments but are produced artificially in nuclear reactors since they decay naturally over time.
Nuclear fission occurs when an unstable nucleus such as uranium splits after absorbing a neutron, releasing energy and more neutrons. These neutrons can trigger further fissions in a self-sustaining chain reaction. A nuclear power plant controls such a chain reaction to generate heat from uranium fuel rods, using this heat to boil water and drive turbines to produce electricity, without producing greenhouse gases. However, nuclear power also produces long-lasting radioactive waste and risks accidents that can kill people.
Primary energy sources exist naturally, like fossil fuels, while secondary sources are produced from primary sources, such as electricity from burning fossil fuels. Generating electricity is inefficient and releases carbon dioxide, worsening climate change. Governments are promoting alternative energy sources like wind and solar that produce electricity without carbon dioxide emissions.
This document discusses different ways of generating electricity including fossil fuels like coal and gas, nuclear fuel, and renewable sources like solar, wind, and tidal power. It outlines some key advantages and disadvantages of each energy source. It also explains how power stations use primary energy sources to boil water and create steam to drive turbines that generate electricity. The efficiency of this process can be illustrated using a Sankey diagram that shows how much of the original fuel's energy is lost versus how much is converted to electricity.
The document provides a review of key concepts for the P6 Exam on radioactive materials. It covers three types of radiation (alpha, beta, gamma), how efficiency is calculated, units of radiation dose, contamination vs irradiation, how radiation affects cells, renewable vs non-renewable energy sources, fossil fuel and nuclear power station diagrams, fission and chain reactions, half-life, types of radioactive waste, and health considerations like ALARA and risk analysis.
Rutherford designed an experiment to investigate the structure of atoms using alpha particles. Geiger and Marsden fired alpha particles at a thin gold foil and observed them with a microscope and detecting screen. They found that although most alpha particles passed through the foil with little deflection, some were deflected at large angles or even bounced straight back. This provided evidence for a small, dense nucleus at the center of atoms, contradicting the prevailing nuclear model. The experiment revealed the existence of the atomic nucleus.
This document provides a sample scheme of work for a 13 hour unit on radioactive materials for GCSE 21st Century Science Physics. It includes 7 topics: radioactive materials, atomic structure, discovery of the nucleus, types of radiation, half life, dangers of radiation, uses of radiation, nuclear power stations, and nuclear fusion. Each topic lists the key concepts, suggested teaching activities, resources, and points to note. The goal is to teach the key required content and skills in an engaging hands-on manner using practical demonstrations and group work wherever possible.
