...Running head: RWBFC Scheduling at Red, White and Blue Fireworks Company Shelia Iceson Operations Management Dr. Kyle Peacock December 12, 2011 Develop a staffing plan for RWBFC in accordance with the constraints stated in the case. This staffing plan recognizes the significant commitment of human resources necessary to accomplish the job and its requirements. It also recognizes that the Red, White and Blue Fireworks Company (RWBFC) must continue to provide a high level of service and maintain the same level of productivity while this project is underway. The Red, White and Blue Fireworks Company’s staffing strategy is to minimize labor costs by staffing only what is needed for current production due to its inability to expand at the current facility. Staffing levels are rebuilt or contracted as determined by production schedules and as reflected by staffing requirements and constraints. To minimize the potential for over or under staffing, hiring should be based on a review of RWBFC’s production schedule and a review of at least 2 to 3 months forecasting. In order to develop the staffing plan for RWBFC the basis of estimate analysis needs to be used, considering the following constraints: * RWBFC needs to operate ten hours a day * RWBFC needs to operate seven days a week * Employees must have three consecutive days off * The manufacturing process requires a minimum of 20 employees The following table represents a simple schedule...

...Chemistry behind Fireworks Did you know that when you see a commercial fireworks display you are looking at chemistry in action. You may have asked yourself “I wonder what is going on to make all those pretty colors and patterns” It is controlled chaos!! I tell you. Let us break this down to the basic we will start with a typical shell. Starting at the bottom we have a lifting charge which contains good ole black powder. The lifting charge gets the party started by creating an explosion after it is ingnited by the fuse. An explosion occurs which produces hot rapidly expanding gases . This is an example of the “Law of Volumes” which is an experimental gas law which describes how gases tend to expand when heated. Since all the kenetic energy is contained in a tube the shell has no place to go but up. This is Newton’s third law in action which states (in laymans terms) “for every action there is an opposite and equal reaction”. The next two stages in the process happen almost simultaniously the bursting charge, explodes out ward dispersing the pellets or stars which give us our colors and patterns. This happens when the ariel shell is at the apex of its climb via a time delay fuse. Chemical Agents Oxidizer, what is an oxidizer? The word "burning" describes the oxidation of a fuel in air. A campfire, for instance, uses oxygen from the air to turn wood (cellulose) into steam (H2O) and carbon dioxide (CO2), among other things. So why do fireworks need an oxidizer...

...As I walked down the boardwalk on the 4th of July in Ocean City, New Jersey I was trying to take in as much as possible at 8 years old. I was listening to the thousands of footsteps, looking at all the different American flags hanging everywhere, and everyone dressed in red white and blue, just as I was. My 6 year old sister walking next to me in a dress similar to mine, along with my 3 year old brother in a stroller, with my oldest brother pushing the stroller and my parents walking behind us, all of us here together on vacation. My grandma would rent a house in Ocean City every summer for my family to stay at with her for a few weeks, always including the 4th of July, so we could witness the fireworks on the beach. We were looking for a place to eat dinner before the fireworks, it was a little before sunset and we wanted to have a spot on the beach before the show started, and before the louder groups of people came to the beach, which were usually college kids renting a house together for the summer. After walking up and down the boardwalk more than a few times, we finally decided on Prep’s Pizza, one of my dads favorite places to eat in Ocean City. While sitting in a bright orange booth at the walk in restaurant, I watched...

...The Chemistry of Fireworks A firework is an incendiary device or material that can be used for signaling or entertainment. There are chemicals located in the nose of the rocket that explode, producing the colors seen. Fireworks were originally created for the purpose of entertainment and today they are still widely used in celebration to mark special occasions. The thrill and excitement generated by fireworks, brightening the night sky and immersing it with vivid displays of color and technicality, is what makes them a crowd pleaser. But behind all the excitement of fireworks, chemistry plays an important role in creating the vivid colors we witness lighting up the sky. The actual chemical reactions that take place in the explosions require the use of oxidizers, reducing agents and binders. While the production of light in fireworks, rely on basic chemical principles such as redox reactions, combustion and the excitement of electrons in metal ions when heated. Redox reactions are chemical reactions in which both oxidation and reduction take place. Oxidation is a process where oxygen is gained, or hydrogen lost and reduction is where oxygen is lost and hydrogen is gained. In order for the reactions to take place in a firework, oxidizers such as nitrates produce the oxygen to burn and reducers such as sulfur reduce the oxygen into hot gases. NO3 (s) + S (s) → NO (g) + SO2 (g) With any explosive device, combustion occurs. Combustion is a process of rapid oxidation of...

...There are many different classes of fireworks from the ones that you see on the fourth of july to sparklers. Even though these two fireworks are completely different they are very close to the same on a chemical level. The chemistry behind fireworks is a series of oxidation and reduction reactions which result in the desired sound and light. This happens as propellants push the firework into the sky. Oxidation reactions ensure that the oxygen needed to burn the mixture of reducing agents and excite the atoms in the light-emitting compounds is produced. Oxidizers used such as chlorates and nitrates and reducing agents such as carbon and sulfur are available off the shelf for people who make their own. Black powder, which mainly contains nitrates, is the most commonly used oxidizer. A look at an explosion under the use of potassium nitrate to provide nitrate ions (NO3-) after decomposition can be represented as, Potassium nitrate potassium oxide + nitrogen gas + oxygen gas. The reaction is more controlled since when reacting, nitrates only release two in every three oxygen atoms, the reaction is not vigorous since not all the oxygen atoms are actively used up. But the nitrates do not provide enough power to propel the firework into the sky and also ignite the package. So they cannot be used in star explosions since they cannot produce temperatures high enough to energize most color metal salts. Star reactions need a temperature ranging from 1700 to 2000°C. This was found by the...

July 4th, 2011: It started out as any other normal day, flags flying through the wind, children laughing and playing, fireworks booming through the air. It was almost as if it had started out being the perfect 4th of July. Carson cried, " Marco, get off of me!" "Relax, he's just playing with you," explained Maddie. "Whatever. Hey Maddie do you want to go to the dock to watch the fireworks?" Carson asked. "Sure," she replied. "Me too, I want to come too!" screamed Marco. "Oh no, you're NOT coming!" they yelled back at the same time, as if they had read each others minds....

...topped only by legalizing marijuana and Kasich running for president. This forward thinking festival shows how Columbus have evolved and become tolerant of all people. Ohio Comic Con also invites everyone to see a different kind of people. Every year tons of people dress up and "cosplay" as their favorite comic book characters. This unique experience shows how obsessed people can become! Quite possibly the biggest event in Ohio is Red, White and BOOM! WNCI 97.9, NBC4, and Pepsi on the waterfront in Columbus host this all day event. There are streets lined with food, drink, apparel, and Fourth of July accessory vendors. WNCI 97.9 has speakers on every corner playing music to keep the party going. Many people camp out and party all day long in their taped off squares. I, personally, love to walk around and experience everything this day has to offer. A fun parade displays different sponsors and public figures while handing out candy to the kids. The end of the night is by far the best part of this event; it features a countdown to the biggest fireworks display in Ohio that is truly breathtaking. I do not believe there is a more powerful event in Ohio and maybe even the...

...The winter sky smothered the earth with a spotless white blanket. I shivered, tightening my lint infected hoodie around my torso. A wave of excitement and fear rushed through me all at once, like a torrent of emotions throwing me overboard. Joe had to be here soon, the more I thought of her the more I began to sweat. I pushed my thoughts aside and look at the sky above which was overflowing with tumultuous, dark, ragged clouds. Cars weaved their way around everyone, their frustrated horns echoing in my ears. The traffic was like a never-ending row of dominoes. Frost covered the edges of the windows in the shops and snow was falling gently from the gloominess, clouded sky. The crowd rushed past me, like a swarm of bees and died away. It was bitter and cold, my teeth clattered and my body quivered as a gust of wind swept past me. The clouds coughed out great gouts of white cotton balls and balloons of sopping moisture. It was an unending cataract of snow sluicing...

...Chinese New Year. Sometimes it is called the Spring Festival. We are going to learn why it is so important to the Chinese people and we will explore some of the cultures and traditions of this holiday. I will point to the world map posted in the classroom and ask the children if they know where China is? The students will respond by saying and pointing to where they think China is on the map. Teacher: We are here and China is all the way over here. China is a country on the continent of Asia. It is the biggest country in Asia and has the largest population in the world. Let’s take a look at this poster I brought in. Here is a picture of the Chinese Flag. Does it look like the American Flag? Students: No, the American Flag is red, white and blue.

...We were passing up through the Atlantic going north across Africa and Europe and arcing down through Asia to come out east of Australia and New Zealand into the Pacific. I do not know exactly where we were but it was already night when I positioned myself at the docking compartment window. I think it was the one facing more starboard. I always get myself mixed up when I go into that module; I can never easily find the hatch again. It is completely night. There are thunderstorms across Africa and lightning is everywhere; bright flashes are going cloud to cloud illuminating the clouds as it arcs from one to the other. It is a private fireworks show. The storm is large and very spread out and at any moment you see 4 or 5 flashes occurring at one time, each one only lasting a moment. The colors range from something orange-ish to blue-white. Some are more like balls of light while others have that characteristic streak shape that you can observe on Earth. It goes on for several minutes. Occasionally a city goes by with lights shining brightly against the backdrop of flashing pulses of light. The cities come in all shapes, sizes and colors and light patterns. Some cities have clouds over them and all that can be seen is a haze of light. For the cities with clear skies, street patterns are apparent...
